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

Sony a7R IV: 61MP full-frame resolution benchmark for serious image-makers.

At 61 megapixels, the a7R IV sits at the top of what a full-frame BSI-CMOS sensor can deliver in a mirrorless body. The 35.7 x 23.8mm Exmor R sensor pairs with the BIONZ X processor to produce 15 stops of dynamic range and 14-bit RAW files that give landscape and commercial photographers the latitude to push files hard in post. Pixel Shift Multi Shooting takes it further still, compositing 16 frames into a 240-megapixel result that rivals medium format for still-life and architectural work, at a fraction of the cost.

The AF system is built around 567 phase-detection points covering 74% of the frame, with subject tracking algorithms that identify and lock onto human and animal eyes during both stills and video. Wildlife photographers shooting through foliage or working tight sequences will find the continuous tracking dependable across the full burst run of up to 68 compressed RAW frames at 10 fps. Even at full resolution, AF and AE track throughout the burst. Crop to APS-C mode and you still retain 26 megapixels, useful for bird work where extra reach matters more than full-frame coverage.

The 5.76-million-dot OLED viewfinder at 0.78x magnification is one of the finest tools for manual focus confirmation available in this class of camera, and 5.5 stops of sensor-shift IBIS backs up that precision during handheld work. Dual UHS-II card slots, USB 3.2 Gen 1 Type-C, wireless tethering over 5 GHz Wi-Fi, and FTP background transfer make this a genuinely production-ready tool for studio and editorial photographers who need fast delivery pipelines. For anyone whose work depends on file integrity and resolution headroom, the a7R IV remains one of the most thoroughly proven full-frame options in the Sony E-mount system.

FAQ

Does the a7R IV really deliver 61 megapixels in burst shooting?

Yes. At 10 fps continuous shooting, the a7R IV captures full 61MP frames with real-time AF and AE tracking throughout the burst - up to 68 compressed RAW or Extra Fine JPEGs before the buffer fills. This holds true even when using uncompressed RAW, though the burst depth drops to 30 frames.

How does the autofocus handle wildlife and tracking?

The 567 phase-detection AF points cover 74% of the frame, with real-time tracking and eye AF that works on both humans and animals. The AF system locks onto subject eyes from distance and maintains tracking through complex movement or foliage - critical for wildlife where you're often shooting through branches or tall grass.

Can I get a 26MP crop without losing resolution?

Yes. Switch to APS-C crop mode and you retain 26 megapixels at 6,240 x 4,160 - useful for bird and wildlife work where you want extra reach but don't need full-frame coverage. The AF coverage actually improves in crop mode, covering the entire frame instead of 74%.

What makes Pixel Shift Multi Shooting worth using?

Pixel Shift composites 16 exposures into a 240MP file (19,008 x 12,672 pixels) by shifting the sensor in half-pixel increments. For still-life, product, and architectural work where the subject won't move, it effectively delivers medium-format-level detail at a fraction of the cost. You process the files in Sony's Imaging Edge software on your computer.

How practical is the 5.5-stop IBIS for handheld work at 61MP?

The stabilization is tuned to the high pixel count - it reduces camera shake enough to shoot handheld at slower speeds than you'd expect at this resolution. The redesigned shutter mechanism adds dampers and a fast-response motor to suppress vibration further. Still, for absolute maximum sharpness, use a tripod and silent shooting mode.

What's the battery life like in the field?

Expect 530 shots with the viewfinder or 670 with the LCD monitor (CIPA rating). In actual bursts and continuous work, many shooters exceed these figures. The optional VG-C4EM vertical grip holds two NP-FZ100 batteries, roughly doubling shooting capacity.

Does the a7R IV handle 4K video as well as stills?

It records 4K (3,840 x 2,160) at up to 30 fps in XAVC S and AVCHD formats, with S-Log3 (14-stop dynamic range) and HLG support. Real-time Eye AF now works in video mode. Super 35 mode oversamples from 6K data to 4K for cleaner results with less moiré. There's no 10-bit codec or 4K 60fps - if those matter to you, look at the A7S series.
