Sony a7R IV Mirrorless Camera Body, Black {61MP}

Sony a7R IV: 61MP full-frame resolution with 10fps burst tracking

The a7R IV pairs a 61MP back-illuminated Exmor R CMOS sensor with Sony's BIONZ X processor, producing files that resolve enough detail to output prints five inches wider at 300dpi than a 42MP predecessor. The 15-stop dynamic range at low ISO gives landscape and studio shooters significant latitude in post, and 14-bit RAW output is maintained even in silent mode. The Pixel Shift Multi Shooting mode composites 16 frames into a 240.8-megapixel file using Sony's Imaging Edge software, making it a credible option for product, archive, and still-life work where medium format costs are prohibitive.

The AF system covers 74% of the frame with 567 phase-detection points, and Real-time Tracking with Eye AF for both humans and animals holds focus with enough consistency that photographers who reviewed it described rarely needing to intervene during single-shot continuous AF work. Burst shooting tops out at 10 fps with full AF/AE tracking. The 5.76-million-dot OLED viewfinder at 0.78x magnification gives manual focusers a level of detail that makes critical confirmation reliable. Five-axis in-body stabilization is rated at 5.5 stops CIPA, which meaningfully extends handheld shooting at the pixel densities this sensor demands.

Dual UHS-II SD card slots, USB 3.2 Gen 1 Type-C, FTP background transfer, and wireless tethering via 802.11ac make the a7R IV a workable primary camera in commercial workflows where speed of delivery matters as much as image quality.

Who It's For

Commercial and studio photographers working large-format print jobs get direct output from 61MP files with 14-bit gradation, plus PC tethering over USB 3.2 and FTP background transfer for tight delivery deadlines. Wildlife photographers benefit from Real-time Eye AF for animals combined with 10 fps burst shooting and 567 AF points covering 74% of the frame, keeping erratic subjects in focus across a sequence. Portrait and wedding photographers gain from the dependable Real-time Tracking that transitions between face and eye detection without manual AF-point repositioning. Landscape and fine-art shooters who need maximum ground-resolution from a weather-sealed body can work the Pixel Shift Multi Shooting mode for 240.8-megapixel composites when conditions allow tripod use with static subjects.

FAQ

How does the 61MP sensor compare to previous Sony full-frame models in terms of output size?

The a7R IV's 9,504 x 6,336 pixel output allows you to print roughly five inches wider at 300dpi than the 42MP a7R III (7,952 x 5,304 pixels). The pixel density demands careful technique, but the 5.5-stop CIPA stabilization helps offset that.

Can the a7R IV track moving subjects reliably during burst shooting?

Yes. Real-time Tracking with Eye AF for both humans and animals holds focus with enough consistency that you can fire continuous AF work and rarely need to intervene. The 567 phase-detect points across 74% of the frame give the system plenty of data to work with.

What file formats does the a7R IV output, and is RAW lossless?

The camera outputs 14-bit RAW, but Sony does not offer lossless compressed RAW. Continuous compressed RAW files are 12-bit. JPEG options are Extra Fine, Fine, and Standard.

Does Pixel Shift work in-camera, or does it require a computer?

Pixel Shift requires processing on your computer using Sony's Imaging Edge software. The 16-frame mode composites into a 240.8-megapixel file, but you'll need a tripod and static subject for best results - think product, archive, or still-life work.

What are the connectivity options for professional workflows?

The a7R IV includes dual UHS-II SD card slots, USB 3.2 Gen 1 Type-C, FTP background transfer, 802.11ac Wi-Fi, Bluetooth 4.1, and NFC. You can tether via Imaging Edge software or transfer RAW and JPEG files over FTP during and after shooting.

How many shots can you expect per battery charge?

CIPA-rated battery life is approximately 530 shots (viewfinder) or 670 shots (LCD monitor). In practice, burst shooting extends this, and you can charge over USB if needed.

Does the viewfinder provide enough detail for manual focus?

Yes. The 5.76-million-dot OLED viewfinder at 0.78x magnification resolves enough detail that manual focusers can confirm critical focus reliably. The display refreshes at up to 120 fps.
