Sony a7 IV: Beyond Basic
An all-arounder that pushes beyond basic, the Sony a7 IV does double duty with strong stills and video performance. An advanced hybrid mirrorless camera, the a7 IV has the resolution and AF performance that appeals to photographers along with robust 4K 60p video recording for filmmakers and content creators.
Sensor and Processor
33MP Exmor R BSI CMOS Sensor
Newly developed 33MP Exmor R full-frame sensor features a back-illuminated design that promotes high clarity, low noise, and vivid color rendering. This design benefits working in low-light conditions and works in conjunction with a broad sensitivity range of ISO 100-51200. The sensor's design also achieves an impressive dynamic range of approximately 15 stops and files can be recorded in raw, JPEG, or the 10-bit HEIF format.
BIONZ XR Processor
Using the flagship-class BIONZ XR engine, high-speed image processing capabilities are available for fast continuous shooting, 4K video recording, and advanced AF tracking performance. 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, using either the mechanical or electronic shutter and with AF/AE enabled. Also, the buffer permits recording up to 828 consecutive uncompressed raw + JPEG frames when using a CFexpress Type A card.
Video Recording
4K 60p Video Recording in 10-Bit
  • Making full use of the high-resolution 33MP sensor and fast processing capabilities, UHD 4K 30p XAVC HS 10-bit recording is possible using the full width of the sensor, offering 7K oversampling for impressive sharpness and realism.
  • There is also oversampled 4K recording, via a 4.6K capture area, with a Super 35 crop, that offers UHD 4K output up to 60p in 10-bit.
  • No recording time limit allows for unlimited clip lengths and the camera's physical design features an improved heat-dissipating structure to promote longer possible recording times; longer than one hour of continuous 4K 60p 10-bit 4:2:2 recording, for example.
  • The a7 IV employs a pair of codecs to suit different workflows: XAVC HS, which uses HEVC/H.265 encoding to retain more detail at smaller bitrates and XAVC S-I, which is an intraframe codec for consistent performance and quality at bitrates up to 600 Mb/s.
S-Cinetone, S-Log3, and Other Color and Gamma Controls
  • S-Cinetone can be used to deliver distinct colors and healthy-looking skin tone rendering that matches the FX9 and FX6 cameras, along with the a1 and a7S III, and is based on technology from the professional Cinema Line cameras, such as the VENICE. This color profile offers natural mid-tones, soft colors, and especially well-controlled highlights.
  • 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 15+-stop dynamic range with increased grading control in the shadow to mid-tone regions of the image.
Fast Hybrid AF System
AI-Based Autofocus
Covering approximately 94% of the image area, a Fast Hybrid AF system incorporates 759 phase-detection points for quick and precise focusing in a variety of lighting conditions with sensitivity down to -4 EV. This focusing system is available for use in all recording modes, to benefit both video and stills applications.
Real-time Tracking and Real-time Eye AF
Borrowing from the flagship AF system, the a7 IV has tuned tracking and subject detection capabilities that lock onto subjects quickly and refines focus accurately on recognized eyes and faces of subjects:
  • Real-time Tracking is an AI-based subject recognition system that recognizes color, pattern, and subject distance information for high accuracy and focusing speed.
  • Beyond just tracking subjects, Real-time Eye AF fine-tunes the focusing accuracy and recognizes human, animal, and bird's eyes for critical sharpness. Real-time Eye AF even maintains focus on a subject's eye when they leave and re-enter the frame, allowing for working in more spontaneous shooting situations.
AF During Video Recording and Additional Focusing Modes
  • Real-time Eye AF is fully supported during video recording, for subject detection and tracking of human, animal, and bird eyes while shooting.
  • For more control over how focus shifts appear during recording, seven-step AF transition speeds and five-step AF subject shift sensitivity controls let you refine how quickly focus shifts from point to point and how smoothly focusing shifts occur.
  • Focus Map is a unique way of visualizing depth of field and functions in a similar way to peaking with a colorful overlay of the scene that indicates which parts of the scene are in front of and behind the focus point depending on the chosen aperture.
  • A feature carried over from the FX6 digital cine camera, AF Assist lets you intuitively switch over to manual focus control for adjusting focus position when working with AF. This is a quick way to shift selective focus between various subjects in a scene while recording.
  • A unique solution to compensate for how certain lenses perform when racking focus, Focus Breathing compensation will automatically smooth focus transitions and maintain a consistent field of view when changing the focus position during a shot. This mode crops into the image slightly and corrects for any detected shifts in composition when focusing is happening. This function is compatible with select E-mount lenses, check Breathing Compensation lens compatibility here.
Body Design, Connectivity, and Streaming
Viewfinder and LCD Screen
  • An improved QVGA OLED Tru-Finder EVF features a 3.68m-dot resolution that is approximately 1.6x higher in resolution than its predecessor for sharper, clearer viewing. This viewfinder supports both standard 60 fps and 120 fps frame rates for smooth motion rendering and its physical design has a long 23mm eye point, 0.78x-magnification, and 37.3° field of view.
  • Perfect for vlogging or other self-recording needs, the side-opening 3.0" 1.03m-dot vari-angle articulating screen can be used in a front-facing orientation or can be tilted up or down to suit working from high or low shooting angles. This LCD is a touchscreen, too, for intuitive shooting control and menu navigation.
Ports and Interface
  • Full-size HDMI A port offers a more reliable connection when working with external recorders.
  • A USB 3.2 Gen 2 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 or powered from the host power source while connected.
  • Both 3.5mm headphone and external microphone ports facilitate greater control over audio recording.
  • 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.
  • USB Type-C port can be paired with an optional Ethernet wired LAN adapter to provide 1000BASE-T connectivity, wired remote shooting, or FTP transferring.
5-Axis SteadyShot INSIDE Image Stabilization
  • Enhanced 5.5-stop effective 5-axis SteadyShot INSIDE image stabilization system compensates for five different types of camera shake encountered during handheld shooting of stills and video and allows users to confidently use any lens, even adapted lenses, for critical shooting 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.
  • Additionally, specifically for video, there is also an Active IS mode that adds even more precise stabilization methods for even smoother footage straight out of camera.
Advanced External Flash Control
Suiting working with flash while photographing fast-moving subjects, P-TTL flash metering is possible in between each exposure when working with lo, mid, or even hi-speed continuous shooting modes. This helps to maintain stable illumination if making low-light bursts and greatly benefits working in changing light or low-light conditions. The updated flash control system also helps to reduce flash trigger lag, uses the camera's AWB information for natural color rendering, and supports adjusting select flash and transmitter units directly from the camera's interface.
Wireless Connectivity and Streaming
  • 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.
  • Supports Visual Story for easy cloud-based deliver of photos and videos immediately after shooting.
  • Live streaming is possible directly from the camera simply by connecting the camera to a computer or compatible mobile device via USB, allowing the camera's video and audio capabilities to be used for live social media and video conferencing.
  • 4K 15p, FHD 60p/30p, and HD 30p recording settings are available and there are also internal Creative Look and Soft Skin effects for a refined image quality straight from the camera.
  • Internal recording is supported to a memory card while live streaming.
  • UVC and UAC standards are supported for improved picture and sound quality during streaming.

Sony A7 IV Reviews

Big step up

By Peter
Rated 5 out of 5
Date: 2022-09-28

This is a surprising step up from the A7iii. Pretty much all functions are better, particularly the focus tracking. One thing I have not seen elsewhere is that it is quite a bit bigger than the A7iii. With the 35/2.8 the A7iii became a small point-and-shoot type camera - not so with the A7iv.

Overheats! (Yes I changed the menu setting for high heat)

By Michael
Rated 2 out of 5
Date: 2022-09-19

The A74 overheated indoors on a cool evening, not even while recording, but while learning and setting up the menus (~40 minutes), and was hot to the touch well before then. This is my job. Am I supposed to film in 1080? Wrap my camera in an icepack? Ask interview subjects to speak faster, or take a break till my camera is ready again? I'm going to give it a couple days of field testing and a firmware update, and if it overheats one more time (in northern NY in mid-September) it's getting sent back to B&H.

Solid All Around Camera

By Thomas
Rated 5 out of 5
Date: 2022-09-17

From the perspective of an enthusiastic amateur photographer. This is the first ILC camera that I've owned myself. Any other shooting I've been doing over the years has been afforded to me by people or companies that let me borrow their gear from time to time. I got this with the Sony 50mm F1.8 with the slow auto-focus, and the Tamron 28mm-75mm F2.8. I've enjoyed both lenses for what they're good at. I've shot a lot of different scenarios, and have been really thrilled with the results. Shot a bunch of high school sports, a bunch of local church events, couple portraits, some group shots, sunsets on the lake, candids at some corporate events, and other numerous things that I can't specifically recall at the moment. The video it creates is beautiful, and captures moments better than anything I've used previously. There were a few times where I wish I had a longer telephoto lens while shooting some sports, but otherwise I don't feel like the gear is ever holding me back. Any time I've missed a shot, it's either been a really challenging scenario that I think any existing auto-focus system would struggle with, or it's been me not using the camera effectively, or forgetting something in my technique. I've never really been in a situation where I felt like the camera failed me in terms of its performance. This camera isn't perfect. There's cameras that shoot faster, cameras that have more megapixels, cameras that are better at low light, cameras that do 4K60 without a crop, and cameras that have less rolling shutter. But this camera is really great at a lot of shooting situations while minimizing its weaknesses. I find myself really liking the layout of the camera. Having the Photo/Video/S&Q on its own dial is fantastic. I think Fuji is the only other one who's does that right now, and I think every other company should copy that feature, because it's a huge quality of life improvement if you need to switch quickly between photos, videos, and custom settings between the two. I know many say, and continue to say that Sony's handling and/or menus are bad in comparison to the Canons, Nikons, Fujis, and Panasonics of the world, and they might be right. But since I haven't used any one brand at great length, I honestly haven't found the menus of the Sony A7IV really difficult or troubling. There's a ton of settings there, and after having the camera for many months, I still feel like I'm merely scratching the surface of what can be done with the settings, but I don't really feel like I'm left overwhelmed by option paralysis or that the menus are too confusing or disorganized to find the thing I need to adjust. Some of the other brands may have better menus, but in my case, ignorance is bliss. I've enjoyed the amount of customization that can be done with the buttons and dials. Just about everything can be remapped to my liking, and there's so many different functions that can be mapped to those buttons and dials. I really feel like I can mould the camera around the way I want to use it. I bought a second battery for the camera as I figured I'd probably need it. However, I have yet to need to switch to the second battery any time I've gone out shooting with the camera. The battery life has been really solid for me. Still glad I have that second battery if I ever need to do a marathon shooting session. In all the shooting I've done with this camera, I've never really needed the speed of CF Express cards. I've only outrun the buffer like two or 3 times since purchasing the camera, and the recovery was fast enough that it wasn't a problem for me. I'm using dual 128GB ProGrade UHS-II/V90 SD cards shooting redundantly, and have been very happy with that setup. This is completely subjective, but I prefer the fully articulating screens like what is in the Sony A7IV. I like being able to hide/protect the LCD screen when I'm not using it, I like being able to put it off to the side facing forward if I'm trying to check something about a scene while in the scene, taking a self portrait or filming myself. It works for me. In conclusion, I like the camera, the battery life, the lens lineup and third party lens support, the quality of the images and video. I like the files I get straight out of the camera. It does everything that it does well enough to make me happy. I know I should have a list of cons, because no product is perfect, and that's the case with the A7IV too, but when it comes down to it, I'm having fun using the camera. There's nothing about this camera that leaves me saying, Man, I can't believe this camera doesn't do that. or I wish this camera would do this....It should be able to do this. I pull the camera out of the bag, I stick a lens on it, and I start taking photos. I'm having fun when I'm using the camera. I'm not finding myself frustrated with the camera after using it for several hours. It's doing for me what I hoped it would do. Now maybe I'd be just as happy with a Canon R6, or a Nikon Z6II, but I'm having too much fun with my Sony A7IV right now to worry about those what ifs. This is a really good camera. If you've got the budget for it, I think you'll be pleased with what you can accomplish with it.
