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

Loving this upgrade

By Nathaniel
Rated 5 out of 5
Date: 2022-05-17

I had just recently purchased an a7iii which I had barely used but was loving when the a7iv came out with massively increased video capabilities in addition to a more resolute sensor and other upgrades. For the increased video capabilities alone, I decided to trade in and buy the a7iv. And massively happy I did! Great camera.

Great camera with small annoyances

By Petar
Rated 4 out of 5
Date: 2022-05-17

For point of reference: I'm a hobby photographer and upgraded from a7 to a7 IV. I also shoot with RX100 VI. I have big hands and usually struggle to hold smaller cameras in a comfortable grip in my hands. At the same time, I don't wish to buy a big and heavy camera. This is what drew me to the a7 in the first place. Great performance from a reasonably sized camera. The a7 IV is noticeably larger and heavier than its older sibling. But in my opinion, the tradeoff is well worth it. The a7 IV fits so much better in my hands and the added controls make using the camera so much better. This, coupled with the updated menu system is by far the biggest upgrades in my opinion. It makes shooting more comfortable, easy and enjoyable. When it comes to the results, the biggest difference I've noticed is improved dynamic range and AF system. Improved dynamic range allows me to shoot higher contrast scenes without having to bracket my shots. Which in turn makes my post production workflow smoother too. The vastly improved AF system allows me to shoot spontaneous photos and capture moments that I otherwise might have missed. As someone who enjoys shooting urban environments, this is golden! One often underrated feature is the new USB-Webcam mode. It cannot be stated enough how great it is to have this natively built in to the camera, instead of having to rely on programs to enable such functionality. Specially since said programs tend to be buggy, unreliable and easily get outdated with new operating system releases (looking at you Sony and GoPro!). There are however some annoyances that I believe could be improved upon. They're not that critical, and I believe that many of them could be fixed by firmware updates. 1. The built in guide is not very helpful. Instead of describing what an option in the menu does, it just says the same thing with more words. 2. The mobile apps for controlling the camera and downloading picture to the camera are quite bad. 3. Missing video options. Why can't I shoot h.265 (XAVC HS) in 30p? The only options available are 24p or 60p. 4. Unclear consequences of picking different RAW formats. The camera can shoot 10fps with compressed RAW but only 6fps in lossless and uncompressed RAW. I wish this was detailed in the RAW format options. 5. Unclear image formats. When shooting RAW, you can choose between Compressed RAW, Uncompressed RAW and Lossless Compressed RAW. Why would anyone pick Uncompressed RAW instead of Lossless Compressed RAW? The only reason I can think of would be that Lossless isn't ACTUALLY Lossless, just less lossy than regular compressed. 6. Wish one could rename the picture profiles instead of just having them numbered. Other than that, I wish the camera had the following: 1. Built in GPS. 2. Built in theft protection. 3. Ability to shoot 4k 60p in full-frame mode (limited to Super-35 today). 4. Ability to shoot Lossless/Uncompressed RAW in 10fps. 5. Built in radio flash controller. To round it up: If Sony would update the firmware and improve on some smaller details, I'd easily give it five stars! But before that, it will have to do with four. My opinion is largely influenced by price, as it's not a cheap camera. In the end, it's a great camera that's easy and comfortable to use.

Fantastic Dream Camera!

Hello! I would like to say this camera has proven to be a great camera, with amazing photo and video capabilities. I have seen countless online video reviews and blogs about this camera, and although some of the short comings like the 4k 60 crop, over heating (with some un-lucky ones), and rolling shutter performance. I feel like these aren't a deal breaker for me, especially since I am coming from a APS-C body. The 33mp is plenty, and is what I would consider a sweet spot for photography, 10-bit color modes for extra flexibility in post video editing, new CF-express slot, and dual UHS-2 card slots is perfect and a welcome upgrade from my previous set up. Overall, I am ecstatic with my purchase, and I have paired this with Sigma's 24-70 2.8 DC DN Art series lens to give me flexibility, it being my first lens, I wanted to cover some of the more common focal lengths in one lens. I have spoiled myself with this camera, and it will be one I will have for many more years to come!

Powerful camera with great autofocus

One of the things I photograph most, day-to-day, is my very fast dog. Both the autofocus and the auto focus area do a good job when I want them, and the controls are very customizable, so when I do want to do everything manually, everything is just where I want it.

The perfect hybrid shooter mirrorless body from Sony

Date: 2022-05-17

I've owned a couple Sony bodies in the past couple of years and I can say the Sony A7IV is now my favorite. I find that the 33 megapixel sensor is the perfect sweet spot for photos and the ability to shoot 10bit 4:2:2 4k video is incredible. As to be expected from Sony the dynamic range of this camera is incredible as is the autofocus performance. I was thrilled to see B&H had it in stock and I jumped at the opportunity, couldn't be more thrilled with my purchase!
