A New World of Photographic Expression

Moving to an even higher resolution realm, the Sony a7R IVA continues the noteworthy series of highly capable full-frame cameras, characterized by impressive stills and video performance and versatility. This fourth edition of the a7R sees the inclusion of an updated 61MP sensor along with faster processing, improved AF performance, and a more well-rounded feature-set for both high-end photo and video applications.

Sensor and Processor

61MP Exmor R BSI CMOS Sensor

Featuring a back-illuminated design, the newly designed full-frame 61MP Exmor R CMOS sensor offers a mixture of incredible resolution with high clarity, low noise, and a wide 15-stop dynamic range. The sensor's structure promotes impressive image quality and a copper wiring layer dramatically improves data transmission speed for creating 14-bit, high-resolution 61MP stills with a native sensitivity range from ISO 100-32000, which can be further expanded to ISO 50-102400.

BIONZ X Image Processor

The BIONZ X engine's high-speed image processing enables fast continuous shooting, 4K video recording, and advanced AF tracking. The quick processing also helps to reduce rolling shutter and other motion distortions for clean rendering of moving subjects.

In terms of shooting speeds, the sensor and processor enable up to 10 fps shooting, at full resolution, for up to 68 consecutive frames, with full-time AF/AE.

Pixel Shift Multi Shooting

This unique compositing mode allows you to achieve even greater resolution than the 61MP sensor affords. Working in conjunction with the sensor-shift image stabilization, this mode shifts the sensor while making 16 consecutive exposures in order to acquire approximately 240.8MP of information for greater color accuracy and detail than possible with a single exposure, along with an impressive image size of 19,008 x 12,672-pixels. These files can then be merged together during post-production by using the Sony Imaging software suite.

Fast Hybrid AF System

An updated Fast Hybrid AF system now employs a combination of 567 phase-detection points, which cover approximately 99.7% of the height and 74% of the width of the frame, along with 425 contrast-detection areas for reliable and quick autofocus and subject tracking performance. This focusing system also achieves especially quick speed and reliable tracking, as well as enhanced low-light focusing response down to -3 EV.

The apt focus system also lends itself to a variety of focusing functions for refined accuracy:
  • Lock-on AF maintains focus on moving subjects throughout the use of a configurable frame that is set over the desired moving subject
  • Expand Flexible Spot employs neighboring focus points to retain focus on moving subjects even if the originally selected point loses focus
  • Eye AF can be used to base focus on recognized human subjects' eyes for portraits and is available in both AF-S and AF-C modes and for both stills and video. Eye AF can be used when photographing animal subjects, too, with any focusing mode when shooting stills.
  • The Focus Magnifier function can be used for critical focus when homing in on minute subject details
  • Rear touchscreen can be used for Touch Focus control and a Touchpad Focus Control mode lets you use the rear screen intuitively while keeping your eye to the viewfinder

Video Recording

UHD 4K Video Recording in XAVC S Format

  • Internal recording of UHD 4K video is possible in multiple frame rates up to 30 fps using the full width of the sensor with 8-bit 4:2:0 color sampling using the 100Mbps XAVC S codec.
  • Oversampled 4K recording is also possible, which uses a 6K capture area with a Super 35 crop for greater detail. This full pixel readout is void of pixel binning for higher quality imagery with reduced moiré and aliasing.
  • Full HD 1080p recording is also supported in frame rates up to 120 fps. The high-speed, 120 fps recording also enables 4x and 5x Slow& Quick Motion (S&Q) movie recording with the frame rate set to either 30p or 24p.
  • In addition to high-resolution internal recording, uncompressed HDMI output also enables the use of an optional external recorder for clean 4K recording with 4:2:2 sampling.
  • 4K video recording also avails the ability to produce 8MP stills during playback by taking a frame grab from a movie and storing it as a separate file.

S-Log3 and HLG Color Control

  • HLG (Hybrid Log-Gamma) support permits recording within a wide color gamut for producing HDR-ready content directly from the camera.
  • S-Log3 is also available for producing a 14+-stop dynamic range with increased grading control in the shadow to mid-tone regions of the image.

Body Design and Connectivity

Viewfinder and LCD Screen

  • Updated OLED Tru-Finder EVF has a 5.76m-dot resolution for bright, clear viewing in rich detail
  • Dedicated High quality setting enables a 120 fps refresh rate for especially smooth playback of moving subjects.
  • The 3.0" 2.36m-dot rear LCD has a touch panel design for intuitive operation and focusing control.
  • Screen tilts upward 107° and downward 41° to benefit working from high and low angles.

Professional Body Design

  • Magnesium alloy chassis assures rigidity, durability, and stability while remaining lightweight. The lens mount has also been improved to better support heavy lenses and the grip rigidity has been improved for more comfortable hand-holding.
  • Extensive weather-sealing, including enhanced sealing around the battery cover, terminal cover, and chassis joints, has been employed to resist dust and moisture for reliable operation in harsh weather conditions.
  • Using the same NP-FZ100 battery as its predecessor, the a7R IVA's battery life is rated for approximately 530 shots per charge with the EVF or 660 shots with the rear LCD.
  • Dual SD memory card slots allow for flexible file saving and handling and can be configured to partition raw and JPEG files or can be used for overflow recording. Both of the card slots are rated to support UHS-II memory cards for faster transfer speeds.

Ports and Interface

  • USB 3.2 Gen 1 Type-C port has been added, in addition to a micro-USB port, for faster, more reliable tethering support. The USB Type-C connection allows the camera to be charged from the host power source while connected.
  • Updated Multi Interface Shoe supports working with the optional ECM-B1M Shotgun Microphone or XLR-K3M XLR Adapter Kit, which provide improved, clear audio recording sound by sending a digital audio signal to the camera, opposed to an analog signal.
  • Both 3.5mm headphone and external microphone ports facilitate greater control over audio recording.
  • HDMI micro (Type D) connector offers a clean signal out for working with optional external recorders.
  • Integrated PC sync terminal for wired flash sync with strobe packs or wireless radio remotes.

Wireless Connectivity

  • Built-in Wi-Fi enables the remote camera control and instant sharing of imagery to mobile devices for direct sharing online, and support for both 2.4 and 5 GHz bands also enables wireless tethered shooting support. This connectivity also provides remote camera control.
  • Use of the Imaging Edge mobile app is benefitted by Bluetooth to maintain a reliable connection between the camera and mobile device.
  • Bluetooth connectivity also allows for location data acquisition.

5-Axis SteadyShot INSIDE Image Stabilization

Packed into the robust a7R IVA is a 5.5-stop effective 5-axis SteadyShot INSIDE image stabilization system that compensates for five different types of camera shake encountered during handheld shooting of stills and video. This allows users to confidently use any lens, even adapted lenses, for critical imaging without encountering blur from camera shake.

For long focal lengths, the system will correct for pitch and yaw adjustments. Macro and high-magnification imagery, on the other hand, will benefit from the inclusion of horizontal and vertical shift compensation. All shooting styles will get usage out of the roll compensation. All 5 axes of stabilization will function at all times, even when used with third-party lenses and adapters or lenses with built-in optical stabilization.

Dedicated Accessories from Sony

Complementing the camera body is a trio of accessories to increase battery life and enhance audio recording capabilities when shooting video. The VG-C4EM Vertical Grip is the dedicated battery grip, which accepts up to two more NP-FZ100 batteries for extended shooting times. Its ergonomic design also enhances handling when shooting in the vertical orientation.

For improved audio recording, and making use of the a7R IVA's updated Multi Interface Shoe and digital audio interface, there is the ECM-B1M Shotgun Microphone, which delivers a digital audio stream directly to the camera for cleaner quality with low noise. For even more advanced audio control, there is also the XLR-K3M XLR Adapter Kit, which is a dual-channel digital XLR audio adapter for connecting external microphones to the camera while still benefitting from the digital audio interface.

I am an eclectic user who shoots Canon, Nikon, Fuji and Sony as the mood takes me and I therefore do not have a foot in any particular camp. This is 5th Sony I have owned, having started with the A7R III and then upgrading to the A7R IV (both of which I traded) and now own an A7C (my wife and I's 'pick up and go' for ad hoc shooting), A7IV (my wife's main camera) and an A7R IVa. Sony camera's take some getting used to, with their confusing menu system (that is marginally better in the A7 IV) and somewhat angular ergonomics. However if you invest the time to get it setup the way you want and you adapt to the angular and less than ideal ergonomics the results are outstanding. Pro's: 1. Autofocus is fast and accurate (lens choice will affect this, but we use, predominately, Tamron lenses and they are super fast and accurate). 2. JPGs are excellent if you spend some time tweaking the color, saturation etc. to your liking, though the out of camera standard settings can be very good. 3. RAW pictures contain a lot of detail that can easily be recovered from the highlights and shadows. 4. Very good dynamic range (see 3 above). 5. Excellent detail. That 60+ MP sensor is very, very good. 6. Low noise in low light, up to a point, and only deteriorates significantly when you crank up the ISO to levels that are really quite ridiculous (25,000 iso). 7. Small and light body. Easy to carry and pack. 8. Because Sony made available their lens mount information along with interface details there is a number of very high quality lower cost options from the likes of Tamron and Sigma. This is a definite negative for Canon and Nikon who do not make available their lens mount information, so you are stuck with their lenses which are often larger, heavier and much costlier or have unacceptable compromises to hit a price point. 9. Excellent battery life. I easily get around 900+ shots from a fully charged batter. Cons: 1. Expensive for an 'older' camera (~$3,500 when not on offer). 2. Not exactly super comfortable in the hand (the Canon R series is very good but feels much bigger). It is however significantly better than the A7R III. it is identical to the new A7 IV. 3. Sony lenses are very, very expensive and quite large, but you do have alternatives that are smaller and lower cost. 4. Complex software update procedure (A7 IV changed this but the A7R IVa still uses the process of connecting directly to the camera using a driver from the computer that needs to be installed and that is unnecessarily complex on a Mac). Summary: A extraordinarily good camera that has some initial usage challenges but once setup and in the hand can product some superb, highly detailed results. Fast and accurate auto focus, excellent dynamic range, small body and available range of excellent lower cost, smaller lenses from alternative manufacturers. Still worth buying even with the rumored possibility of a replacement due in the near future (not confirmed and, with the parts shortages, could be delayed for some time).

The sensor on this thing is awesome. I only wish it had slightly better low light performance but then again, that's where fast primes come into play. Awesome battery life. Had the choice of this or a new a7iv and I'm glad I chose this. I am primary a stills photographer so this was ideal over the a7iv.

Almost perfect, but one unacceptable flaw

By Joseph
Rated 3 out of 5
Date: 2022-05-06

To be fair, I'm not 100% the flaw is the camera or the Sony lenses, but while I love virtually everything about this camera, I don't love the weather sealing. Sensor dust is a HUGE issue on this thing. Even when I change lenses in controlled conditions, it's like there's a vacuum in the body sucking in dust particles. It's wild. I've got 5 other camera bodies (2 Nikons, 2 Fujifilms), and none of them suffer the way this one does.

A small full frame light weight very high performance camera

By Peter
Rated 5 out of 5
Date: 2022-04-06

I have had an on and off love affair with Sony cameras. I have, at present, a Nikon Z7, Canon R5, Fujifilm X T4 and this Sony. This may sound as if I have a bad case of GAS (gear acquisition syndrome) but I have been using all 4 makes for some considerable time and I find that each make satisfies some different picture taking moods at different times. So, I have I never abandoned them, just making incremental improvements as they make changes that seem to make sense. I purchased the Sony A7RIII when it first arrived since that was the first time that they had a usable high resolution version of their A7 series. I quite liked it but was put off by the overly obtuse menus and the angular handling of the camera. It was not an easy camera to use and love. I immediately upgraded to the A7RIV because it was higher resolution and had much better handling (deeper hand grip) but those obtuse menus prevailed, although I was getting used to them. I was getting good pictures without the camera getting in the way and the autofocus was superb. But then I tried a Nikon Z7 and fell in love with the handling and excellent menu structure. However I did not like the pictures I took. I am not sure why but the camera kept failing me or getting in the way at crucial times (usually autofocus issues). However the new Canons came out (and I was a dedicated Canon shooter in the film days and early DSLR era) and decided I had to try one and bought the R6. I immediately sold my Sony and all the lenses and went back to Canon in a big way. I upgraded to the R5 which is a great camera, except for two significant things: size (it feels big to me) and RF lens availability. Canon lenses are either way too expensive or cheap and feel nasty with mediocre performance and you are restricted to what Canon produces and when they produce it. Which brings me back to Sony and this camera. Sony has two major things on its side: Size and available lens options. So I decided to buy back into the Sony ecosystem and bought this A version of the A7RIV. I am aware of the fact that they are probably going to replace it in the near future (although parts issues look as if this may be delayed for a while). And I love it. I have bought the odd Sony lens, but have bought into the Tamron f/2.8 lenses for this camera which makes for a relatively low cost hight performance full frame camera system. I easily slipped back into the arcane menu structure and set it up. It is no longer the king of autofocus (the R5 is just as good for me) but it is still in the top 3 and it is generally the camera I have with me due to its compact size and weight. I use the R5 to satisfy my speed needs and the Nikon Z7 languishes on the side while I decide what to do with it. My Fuji X T4 is used when I want that old shooting experience. That is my fun camera. Pros: 1. Compact size and weight. 2. Excellent battery life. 3. High resolution and dynamic range. 4. Excellent lens options from many manufacturers. 5. Excellent autofocus, although no longer the best. 6. Excellent out of camera JPGs (if set up to your taste). 7. High resolution sensor allows you to crop in for those subjects out of reach with the lens you have on at the time. Cons: 1. Still not the best ergonomics (angular body with buttons in odd places). 2. Arcane and obtuse menu structure that has a longer than necessary learning curve (now updated in the A1, but still not that good). 3. A little expensive for an older design, although the camera still performs in the top tier which is a tribute to its advanced technology. 4. Sony software update process is unnecessarily complex. 5. High resolution produces large sized images (you just need to be prepared for this). 6. Sony lenses are really expensive (some of them are really good, but some of the older ones are slow and not that sharp). Overall I am back in love with this camera and despite its many flaws, it is my goto camera when going out. It does not get in the way of making good pictures.

Asked by: Amanda
No. APS-C/Super35 mode disables approximately half of the sensor, basically giving you less megapixels but because it's still the same pixel density and signal, you'd end up with the same noise with larger grain.
