The Sony Alpha a7S Mirrorless Digital Camera features a full-frame 12.2MP Exmor CMOS sensor and BIONZ X image processor to enable notable video and still image quality with an expansive dynamic range, low noise, and extended sensitivity to ISO 409600. At the sensor level, this full-frame sensor features a unique on-chip gapless lens design, which incorporates small lenses between neighboring pixels in order to increase light-gathering efficiency and promote greater image quality across the entirety of the sensor plane. The sensor and processor combination also avails a wealth of speed throughout the camera system, including a top continuous shooting rate of 5 fps, support for 4K video recording, and a fast 25-point contrast-detection AF system with sensitivity to -4 EV.

Beyond its still image performance, the a7S is also quite adept in regard to recording video. It is able to output uncompressed 4:2:2 UHD 4K video to an optional external recorder over HDMI, as well as record full HD 1080p video in the high-quality XAVC S format at 50 Mbps in multiple frame rates. Extending the video recording capabilities is support for S-Log2 gamma, which helps to expand the effective dynamic range during recording, as well as picture profile options, time code, and zebra marker display aids. Sound can be recorded in the AAC/Linear PCM format via the internal stereo microphone, with a built-in headphone jack for on-board monitoring, or via an external microphone.

Rounding out the a7S's imaging capabilities, both a 3.0" 921.6k-dot tilting LCD monitor and 2.36 million-dot OLED electronic viewfinder are available for image monitoring and review. Built-in Wi-Fi connectivity, with support for NFC, is available, too, for instant sharing of imagery from the camera as well as remote camera control from a linked mobile device.

Full-Frame Exmor Sensor and BIONZ X Image Processor
Incorporated within the sleek body design is a 12.2MP full-frame Exmor CMOS sensor and BIONZ X image processor, which work together to enable an expansive dynamic range with minimal noise and notable sensitivity. The a7S features a native sensitivity range from ISO 100-102400, which is further expandable to ISO 50-409600. Coupled with the large individual pixel size the 12.2MP sensor affords, this camera is well-suited to use in low-light conditions.

The sensor's design also features a new-generation RGB color filter array, as well as a gapless on-chip lens design. Together, these two technologies enable truly efficient light-gathering abilities that further reinforce the low noise, high-sensitivity design. Furthermore, an anti-reflective coating has also been applied to the seal glass of the image sensor to minimize surface reflections, glare, and ghosting for contrast-rich, color-neutral imagery.

The sensor and processor combination also avail a wealth of performance-related benefits to still shooting, including a Speed Priority continuous shooting rate of 5 fps, or a 2.5 fps shooting rate with continuous AF. The contrast-detection AF system employs 25 distinct points to quickly and precisely acquire focus in light levels as low as -4 EV to support working in a wide variety of shooting conditions.
Full Pixel Read-Out with Clean HDMI Out for 4K Recording
Line-Skipping has been the Achilles Heel of video recording DSLR and Mirrorless cameras since video recording was first introduced. Most full-frame and APS-C still cameras have extremely high pixel counts, which is great for still photography, but makes utilizing the whole sensor technically infeasible when recording video since scaling down, say a 36 megapixel image in real time would require a much more expensive image processor and generate more heat than such a compact body could handle. So traditionally these cameras skip lines when recording video, leading to major aliasing and moiré from the large sample gaps as well as decreased resolution and increased noise. However, the lower resolution sensor of the a7S is designed for video recording and features a full sensor readout without any line skipping. This means you will see a sharp image devoid of major aliasing and moiré whether recording internally at 1080p or externally in UHD 4K.

For times when the high quality 50 Mbps XAVC S Codec is not enough the a7S is able to output uncompressed UHD 4K (3840 x 2160) at a 4:2:2 color depth over HDMI to compatible third party recorders. Or, if recording internally to a memory card the HDMI can output 1080p at 4:2:2 for external recorders or HD monitors that don't support 4K inputs. The full list of supported HDMI output signals is:

  • 3840 x 2160 (30p/24p)
  • 1920 x 1080 (60p/24p)
  • 1920 x 1080 (60i), YCbCr 4:2:2 8-bit/RGB 8-bit
Up to 120 fps High Speed Video Recording
In addition to the standard 24p/30p/60i recording formats the a7S is also able to record at much higher frame rates for slow motion playback, albeit at lower resolutions. 1080p video can be recorded in up to 60p using the entire sensor. And 120 fps is possible at 720p using an approximately APS-C sized center crop of the sensor. 120 fps recording allows for about 5x slow motion when played back in 24p.
Customizable Color Profiles and S-Log2 Gamma
To make sure the a7S is able to use its extensive dynamic range while recording video it incorporates extensive customizable color and gamma controls. Users can adjust the gamma, black level, knee, color level, and more. Also users can use the same S-Log2 Gamma Curve that is found on high end Sony Cinema cameras that squeezes up to 1300% more dynamic range into the video signal then traditional REC709, for increased post-production flexibility.
Flexible Timecode Options
The a7S has multiple timecode recording options to meet different workflows. It has the standard 'Record Run" mode that only advances the timecode when recording, as well as "Free Run" timecode that advances the timecode even when not recording, which can be great for syncing multiple cameras at live events. It can also record timecode in both drop frame and non-drop frame modes. When recording internally the a7S is also able to output timecode via HDMI. Timecode output is not supported when outputting 4K over HDMI.
Live Video Overlays
The a7S features many of the same real-time visual overlays and aids that professional video users have come to rely on. These include focus peaking to aid in manual focusing, zebra markers to help judge overexposure, and an audio level overlay for mixing audio. Also focus magnification is available for checking critical focus. These are available in both viewfinder and LCD display.
Audio Input & Headphone Jack
The a7S features a 3.5mm microphone input jack for compatibility with external microphones. And for users needing more the a7S is also compatible with the Sony XLR-k1M XLR Adapter for recording professional balanced XLR audio signals with phantom power and adjustable mic/line inputs.
For monitoring audio the a7S features a 3.5mm headphone jack as well as real time audio levels for a visual reference.
Body Design
Revolving around a compact, sleek body design, the a7S features both a large rear LCD monitor as well as a bright electronic viewfinder. The rear 3.0" 921.6k-dot Xtra Fine LCD features a tilting design (up 90° and down 45°) to benefit working from both high and low angles. Also benefitting visibility with the rear monitor is the incorporation of WhiteMagic technology, which noticeably increases brightness for easier viewing in sunlit conditions. When shooting at eye-level, the 0.5" XGA OLED electronic viewfinder features a high 0.71x magnification and a 2.36 million-dot resolution for precise monitoring capabilities.
Built-In Wi-Fi Connectivity with NFC
Built-in Wi-Fi connectivity enables the a7S to instantly share imagery to mobile devices for direct sharing online to social networking, via email, and to cloud storage sites. NFC (Near Field Communication) is also supported, which allows for one-touch connection between the camera and compatible mobile devices; no complex set-up is required. Once connected, the linked mobile device can also display a live view image on its screen and remotely control the camera's shutter.

Additionally, PlayMemories Camera Apps are also supported via the built-in Wi-Fi connection, and allow you to personalize the camera's features depending on specific shooting styles. Apps are available to suit creating portraits, detailed close-ups, sports, time lapse, motion shot, and other specific types of imagery.

    Hello, my name is Gerardo Campos of Geco Films.
    We have been one of the few that have had the chance of testing the new photo and video camera SONY A7S. You can find our test in vimeo under this name: "sony A7s test geco english subtitles"
    This is the new camera that has a 4K sensor, with a 4K output
    It does NOT record internally in 4K
    One of its main features is its light sensibility.
    There are some reviews going around on internet, but we wanted to do our own testing.
    We filmed simple shots on the street, since we didn´t have the camera for much time.
    We also tested its slow motion performance, since this camera can work up to 120 fps in 720p mode.
    The camera is small and very light
    Easy to maneuver
    The Menu is fairly well distributed.
    This camera´s light sensibility is phenomenal
    We have some images here. I will show you what we captured on the screen and how the camera delivers the image.
    This camera reaches 409.000 ISO, which is insane.
    We tested it in 409000 ISO, but the truth is that we didn´t find anything dark enough to shoot in that setting without burning.
    I´ll show you some nighttime images of buildings
    The image can be recovered since the camera has a very wide dynamic range
    More than 15 stops points of dynamic range
    You can notice this when recovering the scene.
    When you have a burnt or clipped image, although it seems to be unrecoverable. In post production, as you reduce brightness and highlights you will see how much information is held within the image.
    You can recover invisible image data which may be useful.
    Obviously the camera is noisy in 409.000 ISO, inappropriate for high quality use. However the image could be usable up to 50.000 ISO or maybe even 102.000 ISO, if it were later filtered with Denoise or Neat Video.
    It could be useful in a wide range of instances. Such as documentaries were the camera is used in night vision avoiding infra red. In scenes were animals or insects are photophobic.
    This camera would be great for those circumstances.
    It is a small camera, so its transportation is optimum.
    It is light weight and you can use which ever lens you chose.
    You would only need a small tripod, nothing sophisticated and you would be set to work in scenes with no light at all. It is impressive!

    I professionally shoot high school, club, and collegiate sports. I own the Sony a99 and a7. I love the size, WiFi capability, and everything about the A7. However, on both of my above body's, the 24MP sensor is too noisy above ISO 3200. When I shoot sports, especially indoor sports, such as swimming and diving, I often want to use an ISO of 3200+ to achieve the highest possible shutter speed and lowest noise for a given aperture.When I read about the low-noise, high ISO capability of the a7S, with its large photo site, 12MP sensor, I couldn't wait. When the a7S became available for pre-order, I immediately ordered one. It finally came in, and it met my every expectation except one: When placed in "Continuous Auto Focus" (AF-C) mode, using any of the new FE mount lenses, the camera takes from 1 to 3 seconds to focus. This makes the camera useless for indoor or outdoor, high speed action photography and videography.I spoke to Sony several times about this problem. They agree that the camera's focusing system hunts some before it focus locks on the target. Two different Sony reps said that this is a product of "Contrast Only" autofocus used in the a7S and a7R. My a99 and a7 use "Phase and Contrast" autofocus and they both focus much, much, much faster that the a7S or a7R.Now I can see Sony using "Contrast Only" autofocus in the a7R which is designed more for studio or landscape photography, but why Sony didn't take the slow "Contrast Only" slow focus into consideration for the a7S — a camera that could have revolutionized low-light, high ISO action shooting, is beyond me. What a major shame!If you want to see this for yourself, it's easy. Go to any Sony dealer, mount any Sony FE autofocus lens on an a7S or a7R, select "AF-C" in the Focus menu, and watch how much it hunts and how long it takes to focus when the shutter is depressed half way down.I sent the camera back. If this problem can be fixed with firm-ware, I will buy another one, and update my review to 5 stars. Otherwise, two stars is all it deserves, as I shoot moving subjects. The a7 currently is a much better choice over the a7s or a7R for action shooting.

    Comments about Sony Alpha a7S Mirrorless Digital Camera:

    I recently upgraded to the Sony A7s from a canon 60D. I loved the 60D like a son and found it hard to part with it after all these years. Lately I've been getting more and more DOP work and it was time to upgrade.

    The A7s is a powerhouse of a camera built into a small and compact body. Before I get into the video functions which I mostly use this camera for I also have to say that I love the way it feels for photography. After taking a picture using the viewfinder the frame holds so you don't need to take your eye away to look at the LCD screen. Genius.

    The video from this camera is stunning. I've slowly been figuring out how to properly expose Slog-2 which was a learning "curve" for me.

    My favorite part about this camera is that it is fully customizable. I read some complaints that the ISO can be changed by accident because its set to the wheel in the back. Not a problem you can change that.

    All around this camera is a great buy for any filmmaker. My only advice is to pick up some extra batteries. They charge fast but if you going to be outside for a day of shooting your going to want to bring 3-4 batteries with you.

    Comments about Sony Alpha a7S Mirrorless Digital Camera:

    This is a great camera for narrative work. It is incredibly versatile with its ability to switch between full frame and super35 sensor readout, E-mount can be adapted to pretty much everything, and the dynamic range is second only to an Alexa or Amira. It makes a great "B" cam for bigger budgeted projects and an amazing "A" cam for lower budgets.The rolling shutter is a bit more prevalent than I expected, but its easy to shoot around.The batteries are not the longest lifed, so I would recommend buying extras or an external battery.If you are going to shoot S-Log2 outside, high NDs are needed.

    Comments about Sony Alpha a7S Mirrorless Digital Camera:

    I shoot landscapes, portraits, abandoned buildings and I shoot by day and now I shoot by night. A7s opened up a whole new way to be creative. Before I really had to plan my shoots, time of day, locations etc, now I drive and just shoot when ever I see something great.Everything the Sony has designed in this camera is great, does it need improvement? Yes it has it's quirks, but so does Canon, Nikon and the rest. But none of it are show stoppers. The 12MP sensor is more than enough unless you print huge building size posters. The shutter operates fast enough for most action shots, but I think wildlife photographers might have an issue. The lack of FE lens choice is a little stumbling block but that's why you buy the adapter for your A mount lenses. Sony's new lens line up is much anticipated in early 2015.Video from this camera is awesome, with low light features, you just can't go wrong. The only complaint is the record button, Sony could of found a better spot for that but it works and I don't see issues other than getting used to its location. Battery life well every camera has this complaint, solution: Buy more batteries.Light weight, compact and easy to pack when traveling.Controls and menu, same as the A77 and A58 for the most part. Sony is good in that regard trying to keep everything relatively the same through out.

    Almost perfect

    By Obed

    from Houston, TX

    Comments about Sony Alpha a7S Mirrorless Digital Camera:

    I decided to try and give a full Sony lineup a shot. I got rid of my mark 2 and canon lenses and switched to the a7s and Sony lenses. I came to hate the Sony lenses so I got the metabones mark 4 smart adapter and bought canon lenses again and the results couldn't be better!I haven't had an issue filming with the adapter. It's only when I try and use a flash for photo that the adapter stops working correctly. But I just take it off and put it on and that fixes the problem. The flash is also a canon and not a Sony. I don't know if that could have anything to do with the adapter messing up. But my main thing is video so I hardly mess with photo and the camera is perfect as you can get with this lower line of camera. The camera took a lot of getting used to but worth it. This would be a 5 star camera if there was a better option for lenses.

    Comments about Sony Alpha a7S Mirrorless Digital Camera:

    For MY NEEDS, this is almost... ALMOST the perfect camera. Anyone who has been considering this camera probably already knows what it can do and is familiar with it's features. I know I was - until I purchased it. It's an amazing camera however, there are some features this camera doesn't have that other cameras have and vice versa. 1. I wish it would bracket 7 exposures instead of just 5 2. I wish it would auto bracket with a 02:sec timer delay 3. I wish it would meter the exposure while moving the focus point. 4. A longer battery life? (no wonder they included 2) 5. I wish I could do a manual white balance while I was in a Custom mode setting 6. I wish it had the very cool articulating LCD like the Sony A77 or Panny GH4 (THAT I already knew) 7. I wish it had better seals and was waterproof instead of water resistant. I'm sure I'm missing a few more points but I absolutely love the high ISO quality and gorgeous photos it produces. I won't go on and on why I love this camera but the pros outweigh the cons. The only reason I purchase new cameras is to make my job easier. For now, this one is a keeper.

    The best thing out there for low light, the Sony A7s is very good for video with a lot of pro-camcorders features like peaking, zebras and audio levels. Great Slog2 capability. Its 12mp is not amazing for stills, but there is a huge dynamic range and beautiful colors in the RAW files. Great camera overall!

      I am a film maker who was tired of having to a settle for a shallow depth of field while in low light situations. the Sony A7s solved this problem for me,You can shoot 4k video and shoot at ISO speeds up into the 50,000's and still have great looking video. It is new so there are not many lenses (which are expense) but you can circumvent that by buying a lens adapter ring like I did so I can use my dads old F series Nikon lenses

      Comments about Sony Alpha a7S Mirrorless Digital Camera:

      I just purchased the sony A7s as a video production and photography camera. I can tell you already from only spending about 48 hrs with it and just toggling through the menus and the settings that this is a very powerful and compact camera. As far as video goes it has tons of great abilities including lowlight, 60fps @ 1080p, zebras, focus peaking, evf and more. Things that aren't so great about it are the size can actually be too small and cumbersome to deal with if you aren't used to it. I am moving from a another camera system so figuring out which buttons do which for quick access is a little difficult at first but I believe you can customize those functions which is also great. Overall I know this camera is going to be a solid production camera in the video market as well as for shooting portrait, landscape, and studio photography. Definitely not a sports camera as it doesn't shoot high speed photos at all though.

      SONY A7s Videographer's review

            Comments about Sony Alpha a7S Mirrorless Digital Camera:

            i've been using two of these cameras for 2 months in professional situations. I shoot photos, but am primarily a videographer--run and gun and studio situations.one camera works awesome--a dream come true. the other one had problems out of the box. Focus magnifier goes crazy all the time, HDMI firmware was all funky--would only put out a few frame rates under only a few conditions. also the sensor that switches between monitor and view finder couldn't decide which way to go.i sent the one camera back, and got another one with the same problems.the good camera is still going strong.the only other gripe i have is that these cams are really built for DSLR Video, not so great with stills--lacking in pixels, obviously, and you can tell. Sharp video (lighting optional), but the stills are lacking detail.in all other ways i love the __ out of these cameras. really dream machines.

              Comments about Sony Alpha a7S Mirrorless Digital Camera:

              Though I'm not a professional shooter, I have been snapping away for 50 years. I had a long love affair with Nikon that ended 9 years ago when I discovered Leica. I moved back to film and proceeded to develop and scan my BW film. I was in heaven.Then my dedicated film scanner (KonicaMinolta 5400 II) died and I replaced it with an Epson 700. It was okay but not the same quality. And I missed the flexibility of digital as well as the post processing options. And while I bought an M8 and used it for about six months, it was an "epic fail": noisy files above ISO 1250, slow, and digital files that were just sort of "meh." So I sold the M8 and kept shooting film. And though I keep hoping for a different outcome, Leica has yet to make an affordable and reliable digital M.So a month ago I bought a Sony A7s along with Sony's 55mm prime and an adapter for my Leica M glass. And I've discovered heaven on earth.The A7s quiet shutter is silent - quieter than my Leica. I can shoot street photography easier than with my MP. I've shot with my 35mm Summicron, my 24mm Elmar-M, and Sony's great 55mm. Super stealthy. I've walked into places that you could hear a pin drop and captured amazing images . . . absolutely silent. And with the super sensitive sensor and fast glass, I just never think about "how much light is there?" If I need to, I just move the ISO up . . . last night I wandered the neighborhood and captured images at 25,600 and there was no discernible noise. A.M.A.Z.I.N.G.And though I never thought I'd do this, I find myself holding up the body with the LCD screen in view, using focus peaking, and firing off a frame or two. It's great to be able to adjust the rear LCD downward, hold the Sony above my head, and using Leica glass, capture a scene. That's simply not possible with an M body unless you move into hyperfocal shooting. But with the Sony and focus peaking, I can open my lens wide (f 2.0 on my Summicrons), use focus peaking to isolate the subject, and capture a perfectly focused image from a position over 9 feet above the ground (I'm a tall guy).The Sony A7s body is small and lighter than my MP. And the sensor: OMG. If there's but one photon of light in free space, the Sony's sensor will find and capture it. In fact using the 7s is like shooting with a night vision scope in full color. It's so sensitive that I have to reduce the image's brightness in post to restore the darkness of the original scene.The manual focus peaking works like a charm. The buttery smooth manual focus Leica glass works great and I shoot wide open at f 2.0 all the time. And for rangefinder purists, the EVF of the Sony enables me to actually SEE what's in the frame of my long throw Leica glass. I'm even going to drag out my 50 year old 135mm f 4.5 Hektar lens because now I can focus it! And if I have any question about the accuracy of the focus peaking, all I need to do is press one button, bring up the magnification frame, adjust focus if required, and shoot.I use the WiFi file transfer capability all the time. Combined with Sony's somewhat clunky "Play Memories" app on my iPhone and iPad, I transfer only those images I want to post process. Then using Lightroom Mobile, Snapped, or anything else I have available, I process the images and post to my favorite photo or social media sites. No hardware adapter needed . . . just connect peer to peer to my mobile device and transfer the images.And the video? Honestly I'm a stills shooter. I'll be capturing some videos of my granddaughter shortly and it'll be fun but I'm the wrong guy to ask about the capabilities. And for post processing? I use Tonality Pro on my Mac to produce phenomenal monochrome images. Is it exactly like Kodak Tri-X or TMax? No. But it's pleasing and fun.Is there room for improvement? Sure I'd like to see more pixels but the sensor in the A7s is so sensitive I don't even think about "low light." If there's a photon, there's a picture for me. Sony's A7s is incredible. I'll continue to shoot with Leica glass but for the body, it's going to be Sony.

              Comments about Sony Alpha a7S Mirrorless Digital Camera:

              There are a lot of things to like about this camera. It does video beautifully, and the S-LOG 2 flat profile is quite useful. The first time I took a picture in complete darkness, I was amazed at how well it picks up even tiny amounts of light -- even compared to the 5D3. I found the EVF to be quite fast in comparison to others, and the technology is definitely getting better -- although it's still not perfect. For low-light situations and video, this camera excels. Astrophotography? Heck yes. However, it's not an all-around workhorse like the 5D/1D series and other professional DSLRs.There are downsides, of course. It's slow, and the lag makes it basically unusable for sports and action photography. But then again, it's not really made for that. My biggest problem is that fact that it has very little, if any, weathersealing. Sony initially claimed it did, but then online camera blogs found out the a7 series does not, and Sony removed the text stating they do from their documentation and website. It's not built like a professional -- multi-thousand dollar DSLR. Especially the tilt-screen feels quite fragile on the hinges. It has quite a lot of purple amp glow, especially at higher ISOs and long exposures, EVEN with LENR and High ISO NR turned on. Using APS-C mode fixes this issue, but then what's the point in buying a full-frame camera? Battery life is completely unacceptable. Be warned, you basically have no choice but to carry multiple batteries around.Overall, it is a step forward for Sony. Their cameras are getting better. However, they need to build their professional cameras at an acceptable quality for their price range. Professionals put their cameras through a lot of punishment, and I don't feel the a7S would be able to stand up to it. So, I can't see people selling their Canon L glass for these quite yet. The Alpha series is improving, though. Keep going, Sony.

              Comments about Sony Alpha a7S Mirrorless Digital Camera:

              I got and use this camera mostly for it's video functions. Coming from Canon DSLR setup, this was a significant upgrade. Comparing HD footage from the A7S and 5DMIII is just completely different, the Sony footage is ALLOT sharper. Coupled with good control of the S Log2 (PP7) profile, you are really given allot more dynamic range. The colour-grading ability is also much higher. Although it does not record 4K internally (and not externally in a user-friendly way yet), this is a huge step forward for me.There is a bit of a learning curve regarding shooting in S Log2. Personally, I get the best results by over exposing, without blowing highlights, then bringing the footage down in post.Focusing in S Log2 is a challenge, with the super flat profile, it can be very hard to see where you set the focus. The peaking feature is very helpful here. I do find myself double checking, zooming into the area to check before hitting record. You can actually also zoom into the footage during recording, without the outcome being cropped.Native ISO on S Log2 is 3200. So no matter what lens or aperture you plan on using, a ND filter setup is a must in my mind. I keep referring to S Log2, that is really the only profile you should record in. You are not using the cameras full potential otherwise.The ISO performance of this camera is just insane. That only applies if you over expose the video and bring the footage down in post. Bringing up a underexposed scene will end up quite noisy, that also applies to base iso 3200 for S Log2.Looking forward to unlocking the 4K feature!

              Got this camera a week ago at B & H and had a couple of quick tests, it took my breath away, such crisp clear image up to almost 20.000 ISO and I can dare to say more, the noise isnt as bad as you might think. This is a camera made mostl y for video purposes obviously because at pictures the MK III from canon blows it away, the S-log 2 is so awesome, too bad you need to be at 3200 ISO in order to use it but nothing a good ND filter cant fix! Battery life is a meh, you need at least a couple of them but hey, it's not so bad just turn off wifi.

              Comments about Sony Alpha a7S Mirrorless Digital Camera:

              Soy usuario de la gama alta de Canon hace varios años. Abandone el formato ASP-C por los problemas de ruidos, baja profundidad de campo y latitud. Hace años de desembarque en el Full Frame de la mano de Canon 1D MIII (1,3x) y recientemente Canon 5D Mark III con 24-70 f2.8 L y 70-200 f2.8 L. Estaba contento con los resultados de mi cámara, muchas veces acudía a un flash de apoyo y recientemente comencé a usar 50mm 1.4 buscando lenes mas luminosos en condiciones de poca luz. ¿El problema? El peso y la poca discreción de un equipo tan grande y pesado. Finalmente pensé en adquirir una segunda cámara para viajar mas liviano y llamar menos la atención y B&H me recomendaron la SONY a7S. Seguí el consejo y para mi sorpresa hoy es mi cámara principal. Más latitud, más ISO, menor peso y discreta. Una cámara que con el 24-70 f4 solo pesa 980g con Full Frame y saca fotos en la oscuridad. La resolución de 12,2 MP no es problema en absoluto. La probé en NYC recorriendo sus calles con más de 10.000 disparos y en el 99% de los casos fue efectiva.Puedo remplazar con está cámara a las Canon 5D MIII, no en todos los frentes, pero es lo que buscaba para viajar liviano sin perder calidad.

              Everything I wanted. I only wish that you could tell during the purchase that a 64Gb sd card it's needed for better quality videos.

              Comments about Sony Alpha a7S Mirrorless Digital Camera:

              I was trully impressed with low noise and exceptional low night capability of this camera. I compare this with my Nikon D800e and even Hasselblad H4D 50MS. The picture quality is on par with the big boys providing one use a quality lens. I bought the Voigtlander 50mm F1.1 and to try out on this and it picture quality in wide open is very close to my Nikon 50mm f1.4 (or I would say a little sharper). Comparing with the Hasselblad 100mm f2 is still a bit lag of overall corner sharpness but is close.
