Rokinon 12mm f/2.0 overview

  • 1Description

The black, Canon EF-M mount Rokinon 12mm f/2.0 NCS CS Lens is a prime wide-angle lens designed specifically for use with APS-C sized image sensors. Providing a 35mm-equivalent focal length of 19.2mm and a broad 98.9° angle of view, this lens is well-suited for architectural, interior, and landscape images. Its fast f/2.0 maximum aperture is further beneficial to working in low-light conditions.

Three extra-low dispersion elements and two aspherical elements have been incorporated into the optical design to minimize chromatic aberrations and distortion in order to produce sharper images. Additionally, a Nano Coating System (NCS) has been applied to the lens elements in order to reduce surface reflections and prevent lens flare and ghosting for improved light transmission and more contrast-rich imagery

    Rokinon 12mm f/2.0 reviews

    12mm f/2.0 NCS CS Lens for Canon EF-M Mount (Black) is rated 4.7 out of 5 by 11.
    Rated 5 out of 5 by from Great lens at a great price I bought this to use on my Canon EOS M5. I just shot an event and used it for 50-60 shots. It worked great. Don't be concerned about the manual focus and manual exposure. At this focal length almost everything is in focus plus the camera has a focusing aid that makes precise focusing easy. Exposure can be set many differant ways. I mostly used the TV setting with the speed set at 1/60. I stopped down the aperture to 2.8 and let the auto ISO adjust for correct exposure. No problems. The lens is very sharp and the construction seems good. This is a cost effective high speed add on lens. The M5 with the 18-150 zoom and this lens just became my travel kit. I'll leave the big DSLR at home.

    Rated 4 out of 5 by from Nice Quality - Needs Custom Set Up I'm giving thanks I ordered this lens. Just got it. Love the way it looks & feels on the EOS-M3. Nice M form-factor. Outstanding depth of field (it's a super-wide!). And f2.0! I have the 22mm f2.0, and I'm glad I went with this faster wide prime vs. the new 11-16 zoom. Metal construction, feels nicely heavy, solid. Focus ring is tight, but this is good. There is a very slight play in the lens-to-camera mount you can feel when focusing. I wish it were totally solid, but doesn't seem to affect performance. Lens hood is ok. The twist-and-click bayonet mounting is not the most secure, but it clicks home solidly for a plastic hood. The M3's focus peaking works great!!! I'll post some pics soon. NOTE: You must change a custom setting for the camera to work with this lens. Not only should you go full manual (M), but you must also set the camera to Release shutter w/o lens. It took me awhile to find the setting. Here are the steps: Turn camera on. Set mode to M manual. Hit the MENU button. Go to the 3rd menu (camera icon w/dots underneath). Scroll down to C.FN III: Others and hit the SET button. You should land on page 1. Use the > button on the touch screen or click the right side of the scroll wheel to go to page 2. (It took me forever to find this!) Enable: Release shutter w/o lens! Exit MENU. HAPPY SHOOTING!

    Rated 5 out of 5 by from Excellent Product I am using the Rokinon 12mm f/2 lens on a Canon EOS M5. I was a little apprehensive about buying a manual focus lens but as it turns out I had virtually no trouble achieving accurate focus using the M5's focus peaking feature and Rokinon's smooth focus quality. The images from the lens are pin sharp with pleasing color and contrast and show little distortion. I would not hesitate to buy another fast, manual focus lens from Rokinon or some other manufacturer. Thanks, Rokinon and B&H for providing us Canon mirrorless camera users with an excellent fast wide angle lens at a very reasonable price.

    Rated 4 out of 5 by from worth the money Had read lots of good things about this lens for other mounts, so it actually was a factor in buying an EOS-M, since Canon only has 2 lenses in the USA. Not disappointed. Light, sharp and fast. Accurate distance scale allows me to use it for most shooting. When I need critical focus I use the manual focus zoom on the camera. Slight barrel distortion, but not as bad as the wide angle zooms I have been using. I use this lens on the EOS-M around my neck as a 3rd body/superwide lens combo when using fast primes on the other 2 cameras for available light situation.

    Rated 5 out of 5 by from Magnificent image quality. (EOS M3) I am not a photographer but in the arts and design fields and have needed to take publication-level photographs since the mid-1980's. This lens can produce really great images on the EOSM3. The wide angle doesn't really distort the image much as a wide angle can do (not to my problem at least) and the images I get are real crisp and full of color, compared to many previous lenses that sometimes would have a dullness or lifelessness to the image. Lots of possibilities with this lens and it is compact enough that I'll bring it along. Having said that, please note this is a completely MANUAL lens: You have to adjust the focus, aperture and speed. Which is great fun but can be a challenge for those who are used to point-and-shoot. In other words, this can take beautiful photographs on a tripod, in a studio and where you set-up your image. Going shooting around-town means you make time for adjustments for the first shot, then some to the following ones, depending on the sky cover or time of day etc. For me that is part of the art of photography. For someone raised in the instant photo sharing world it will be a learning curve. Very happy with the quality! Other minor things: -My lens cover tends to be on the loose side and has fallen off while on the camera while in a shoulder bag. -For setup: When this lens is on, you adjust the dial to M and from there you can go in the menu to bypass the automatic functions. -Most of my images are shot beyond the +/- 120cm (3-4 ft) focusing distance, so focusing is not a problem. However as with many other lenses, the full distance is NOT at the very end of the turn, but slightly short of it. Check by testing. -For close-ups, I prefer an eye piece on the camera for proper focusing. -Comes with a nice padded (tight fit) lens-bag.

    Rated 5 out of 5 by from Small, wide, fast, and Sharp! I bought this to replace my Rokinon 16mm f/2.0 that I had been using on my EOS-M mirrorless via a tube-adapter. The 16mm is a fantastic lens, but the 12mm is even better. I love primes because they are so much sharper, faster, and smaller than zooms, and this lens is no exception. I don't shoot charts, but I am a chronic pixel-peeper, and this lens exceeds my expectations for something this wide. It's tack sharp wide open, and absolutely stunning when stopped down to f/4. At f/2 the vignetting is pronounced and decreases as the lens is stopped down, but I usually like some vignetting for wide angle shots. In any case, vignetting is easy eliminated in post-processing, so I consider this a non-issue. In areas of sharp contrast around the edges of the photo, you do get some purple fringing, which is annoying, but it's really not too bad for something this wide. Over all, the image quality from this lens is impressive. The DOF with this lens is amazing. When stopped down to f/11 I can be perfectly focused on something a few inches away and still clearly see the background at infinity, or when focused at infinity, the foreground is only slightly out of focus. The option of f/2 gives impressive background blur for something this wide. At f/2, the bokeh is round and pleasant, and when stopped down just a bit, the 6-blade aperture still creates a well rounded bokeh. On my EOS-M, it has the same FOV as a 19mm (full-frame equivalent). The angle of view is just wide enough to stand in the corner and capture the entire room. Combined with the low-light capability and the sharp optics, this is definitely a go-to lens for anyone who shoots a lot of interior spaces. The build quality is pretty good - mostly plastic, but feels sturdy enough. The aperture ring is crisp but easy to turn - no complaints here. The focus ring is smooth, but much more sluggish than I am used to in manual focus lenses. It feels like they used a high viscosity grease in the helicoid. At first it was a little disconcerting how hard it is to turn, but once I started using it, I never found myself needing to turn the focus ring nearly as fast as with some longer focal-length lenses, and I really did not notice it when in use. Part of the reason for this is because it can focus as close as 4, and about half the rotation of the focus ring is for distances <1', so most of the time you are only going to be rotating the ring a small amount. Some people might find the stiff focus ring a little off-putting at first, but with this much DOF, you never need to turn the focus ring all that much. It's not difficult to turn quickly, just stiffer than most lenses. I have actually grown to enjoy the solid feel of the focus ring, as it's buttery smooth and easy to turn when you move it slowly. I think it would be very nice for video. Probably the best feature though (other than the image quality), is how small it is. Other than the very front of the lens, most of the barrel is the same diameter as the EF-M 22mm f/2, which is the smallest interchangeable camera lens I've ever used. I honestly don't use a wide-angle all that often, so i'm glad this one is small enough to always have with me for those times when I just need something wider. It easily fits in a coat or cargo-pants pocket for walking around, but it's also small enough that I can fit it, the camera, and several other lenses in a 1200 pelican case for when I go kayaking or caving. I won't have to make the tough decision of whether or not to take it with me. The lack of autofocus is really not a big deal with a lens this wide, and stopped down a bit, everything's in focus anyway. I almost always shoot with aperture-priority, so the manual aperture is kind of a non-issue for me. With optics this sharp, fast, and wide, the minor drawbacks are kind of trivial, especially when you consider most lenses this good cost more like $2000. I really like this lens and would recommend it to anyone needing a sharp wide angle on their mirrorless camera. This is definitely my new go-to lens for cave and astro-photography.

    Rated 5 out of 5 by from Amazing Sharpness The only lens I've owned that requires little or no sharpening straight out of the camera. Lightroom adds a small amount of sharpening when importing RAW files but even that's not needed. I like the back to basics manual everything with this lens. Put this same lens on a Sony A6000 and the playing field is leveled as far as image quality is concerned since AF is not possible.

    Rated 4 out of 5 by from First Impression of the Rokinon 12mm Just received my Rokinon 12mm f/2 in the mail today from B&H. To start this review, let me provide a preamble about about this lens: I've been very excited about the debut of this lens since it was first announced. I have previous experience with the original Rokinon 8mm f/3.5 fisheye for Pentax and found it to be a fantastic lens with a lot of value. I've since moved on to other camera bodies and lenses, but still pull out the old fisheye on the occasion I need it. Now, Samyang offers up a new rectilinear wide-angle in this roughly 20mm equivalent (18-19 for ASP-C and 24mm for Micro-Four-Thirds) lens. This particular combination has been somewhat of a dream configuration for me. It's the best of both worlds - a bright fast aperture allowing for fast shutter speeds and low light photography combined with a pleasingly wide (arguably ultra-wide) lens. As of right now, I'm not aware of a 20mm f/2 offered for ANY camera system; at least not within the range of the average consumer. Caveat: Yes, I know that crop sensor will make the f-stop equivalents into something more along the lines of a f/2.8 or a f/3.5 as far as depth of field is concerned --depending on your camera system--, but for the purpose of shutter speed and photographing in low light, it still remains an f/2; if that doesn't make sense, just don't worry about it and be happy with the lens!. So, this lens is somewhat ground breaking as far as the range of possibilities it offers. A word about Samyang: Most already know this, but it bears keeping in mind that Samyang is market under different brand names including Rokinon, Bower, Bell, Vivitar, Pro-Optic, and likely many others. Look for deals. The company has built a reputation on offering completely manual lenses (No auto-focus, no aperture control, no EXIF data, and depending on your camera, maybe not even focus assist) with glass optics that rival or even exceed offerings from name brands like Canon, Nikon, Sony, or Ziess for a fraction of the cost of big name brand lenses. No joke, look at the reviews. Now, all that goodness usually involves a compromise, and the signs of compromise are usually present, but for the most part they are things that are easy to live with, especially with an extra $500 to $1000 dollars in your pocket). I'll look at the cost-saving measures employed in this lens shortly. Overall, Samyang lenses function best as slow, thoughtful devices for considerate photography. The also work well for cinematography on the cheap as you don't have to fight ugly auto-focus mechanisms to manual focus. They're going to be a poor choice for fast action shots unless you're experienced at pre-focusing. A word about this type of lens: If you've never used a prime lens before, this is not a bad place to start. I'm not opposed to zoom lenses, but my heart is invested in prime lenses since I grew up in the camera world using them. For some people, the inability zoom is a big turn off, and in the case of ultra-wide lenses, this limitation is even more obvious. Framing is difficult because the lens literally brings so much of your surroundings into the picture. This lens will reward the diligent, however, and provides some brilliant pictures when everything lines up. This lens is also a bright lens, meaning that it has a large aperture opening available. As I previously said, this allows for low light photography and fast shutter speed but it also means that wide open the lens optics are typically compromised in some way (otherwise we would all run around with 10mm f/1 monsters that sell for 50 bucks). More on that later. Now, on to the lens itself. I happened to obtain the Rokinon badged version on the lens in the Canon EOS-M Mount. This lens is very exciting if you happened to pick up an Canon EOS-M for a multitude of reasons. For starters, it's only the third lens offered for the system in the US (there is a wide angle zoom available overseas, and supposedly Canon will continue to support the EOS-M system with other lenses later this year). Secondly, it is the only wide angle offering available in the US for the EOS-M with the exception of some other Samyang lenses that are also offered in the M mount. And lastly, since it is manual focus only, the whole auto-focus issue of the original EOS-M camera becomes a moot point. Users of other systems may have focus-peaking or other means of assistance available. First impressions: It comes in a simple white box with a simple plastic mould to protect it from damage in shipping. A chintzy felt bag is also included in the box, and it will probably stay there until I sell the lens to increase resale value. The lens itself feels hefty for its size and well machined. It maintains a small-ish form figure, although once mounted to my EOS-M most of the size benefit to a mirror-less camera is negated. The outside is plastic with clearly marked values for the aperture a traditional focus scale is also provided. The mount for the camera is solid metal. It clicks into the camera nicely but with ever-so-slightly more play than my name brand Canon 22mm f/2. It wobbles just a tad if I force the issue (to be fair, some Canon lenses do this, too). The aperture ring clicks at half-stops between all values. It feels solid, silky, and quality. A shiny red ring sits between the aperture and focus scale. It allows me to pretend I've bought an expensive L series lens, but provides little value beyond looking nice. The focus ring itself is made of ribbed plastic that feels to be of quality. The focus ring is heavily damped, even more so than my old Rokinon 8mm fish-eye. The front element has a bulbed glass front recessed behind a plastic filter ring. The 67mm filter ring is very convenient for adding affordable filters. Many lenses with angles this wide have extremely inconvenient (i.e. expensive) filter sizes. A plastic detachable lens hood is also included. The hood is flat plastic (no flocking on the innards), and clicks into place. It bends with pressure, and I wouldn't be surprised if the hood were to break if the camera were dropped onto concrete from carrying height. It feels a little cheap compared to the thicker plastic used in the rest of the lens. Still, it's nice to have it included Ahem, Canon. The included lens cap is a modern front-pinch style, and it surprisingly nice. In Use: Mounted, the lens feels nice and doesn't get in the way. I've already mentioned the stiff focus ring. It' a tad unfortunate because it makes the play in the mount a little more glaring and also because it makes switching focus quickly more difficult. On the plus side, you are not likely to bump the focus out of place, which can be a problem on a lens this small. On the EOS-M I was able to stack two regular thickness filters without any vignetting; although with a regular UV filter and a old-school thicker-than-usual polarizer stacked I did start to get hint of vignette in the corners. In the past, Samyang lenses have had a reputation for miscalibrated focus rings. You can manually recalibrate them with the help of several websites, but it's still pretty inconvenient and irritating. Happily, my copy seems to be spot on, and I was able to get a sharp shot of a water tower at infinity at f/2 with the focus moved to its hard focus stop position. At the other end of the focus scale, the minimum focus distance provides reasonable close-ups of objects at 0.2m (.66 ft). I tried throwing a close-focus filter on the front of the lens and it only slightly decreased the minimum focus distance; an extension tube from official parties is not available yet for the EOS-M system as far as I'm aware. Third party extension tubes are probably made by someone somewhere (or will be soon I'm sure). The aperture ring ranges from f/2 to f/22 and doesn't get in the way during use. The Optics: In short, the optics seem to live up to Samyang's reputation of making quality lenses. I'm by no means a professional lens tester so take this review with a large grain of salt. The lens is appears very sharp in the center and mid center at f/2. It does seem to lose a small amount of quality in the far corners; this is not particularly concerning in a lens this wide, especially at an aperture this large. The lens continues to sharpen up in the corners when stopping down, although the corners don't seem to catchy up with the awesomely sharp center. Diffraction stops maximum sharpness somewhere around f/8-f/11. Flare appears well controlled. The biggest optical caveat is going to be chromatic aberrations (pink/purple edges) visible at all edges and corners of the frame in high contrast areas. Stopping down helps but they're still visible even at f/11. It's by no means a deal breaker, and the aberrations are easily correctable with most photo programs. Just be aware that it's the price you'll have to pay for having an f/2 ultra-wide angle. I haven't tested for coma (bright light sources that become smears in the corner), I'll save that for professional testers. I haven't owned any other ultra wide angles besides the Voightlander 20mm f/3.5 (Hey, sorry I like primes) and to my eye this lens beats it handily in overall image quality. My Canon 24mm f/2.8 IS on full-frame is not as wide, but has better image quality overall. Overall, I'm pleased with what I see, especially for the price I paid. A couple of other thoughts: The Bokeh (out-of-focus rendition) on the lens is awesome. At you can get some really nice blurs with pleasing highlights at minimum focus distances. The six bladed aperture is less pleasant, but functional. Most modern lenses include 7 , 8, or 9 blades to get better bokeh at intermediate apertures, and to provide better star highlights when photographing at night. 6 blades are present on Canon's 14mm f/2.8 lens for what that's worth, and they're certainly not evil, just not exciting. Conclusion: For the money, I'm very pleased. There are a variety of good reasons NOT to buy this lens, but if you can live with the cons, this lens really does represent some awesome value. After the use I put it through so far, I would buy this lens again. I plan to give it some more extensive testing in the next several weeks. ---Summary--- Good For: Sharp pictures, Prime Lens junkies, Astrophotography, Budget Photography Bad For: Action shots, Name brand aficionados, Best Image Quality Only
