Sony a7R II Mirrorless Camera Body, Black {42MP}

Sony a7R II: 42.4MP full-frame BSI-CMOS with 5-axis stabilization.

The a7R II puts a 42.4-megapixel back-illuminated full-frame sensor in a weather-sealed magnesium alloy body, and the BSI architecture gives it a measurable low-light advantage over front-illuminated sensors of comparable resolution. ISO extends from a native 100 to 25600, with expanded settings reaching 102400, and the Bionz X processor keeps noise well-controlled across that range. The 5-axis in-body stabilization is rated to 4.5 stops CIPA, which means every lens you mount gets that benefit, native FE glass, A-mount glass via adapter, legacy manual-focus primes, all of it.

The 399-point focal-plane phase-detection AF covers roughly 45% of the frame and performs reliably in continuous mode at 5 fps. Face detection and Eye AF are both available, with Eye AF assignable to a custom button for quick access during portrait sessions. Video runs to 4K UHD at 30p internally via XAVC S, with full-pixel readout and no pixel binning. The clean HDMI output delivers YCbCr 4:2:2 8-bit to an external recorder, and S-Log2 is accessible through the Picture Profile menu for shooters who need latitude in post. A 3.5mm microphone input and headphone monitoring port round out a genuinely capable hybrid production setup. At 625g with battery, this body gives you full-frame resolution, stabilization, and 4K in a package that fits a coat pocket, a combination that still holds up as a serious working tool.

Who It's For

Landscape and architecture photographers get a 42.4MP RAW file with enough resolution to support large prints and aggressive cropping, paired with 5-axis stabilization that keeps handheld long exposures recoverable. Portrait shooters benefit from Eye AF in continuous mode alongside a phase-detection system fast enough to track slow-moving subjects at shallow depth of field. Documentary and interview videographers will find 4K internal recording with on-sensor phase-detection AF, capable of refocusing during a take without hunting, genuinely useful on a full-frame body. Travel photographers carrying adapted legacy glass get in-body stabilization on every lens they own, which changes the math on what's shootable without a tripod.

FAQ

What's the advantage of a back-illuminated sensor on the a7R II?

BSI architecture collects light from the rear of each photosite rather than the front, reducing obstruction from circuitry. This gives you better low-light performance and cleaner shadows compared to front-illuminated sensors at the same 42.4MP resolution.

Can I use the 5-axis stabilization with older lenses?

Yes. The stabilization works with any lens you mount-native FE glass, Sony A-mount lenses via adapter, manual-focus legacy primes, all of it. The camera needs focal length data to optimize compensation; native lenses pass this automatically, while adapted lenses may require manual entry.

How does the autofocus perform in continuous shooting?

The 399-point phase-detection AF system maintains focus during 5 fps continuous shooting with moving subjects. It performs reliably with native lenses and can track cyclists or other moderately fast movement across roughly 45% of the frame. In low light with bright lenses (f/2 or faster), it can focus down to -2EV.

What video formats does the a7R II record internally?

4K UHD at 30p, 25p, or 24p in XAVC S at 60 or 100 Mbit/s; 1080p at 24p, 30p, or 60p; 720p at 120p. All record internally without pixel binning, pulling full-width resolution before downsampling. You also get a clean HDMI output for external recording in YCbCr 4:2:2 8-bit.

Is Eye AF available in continuous mode?

Yes. Eye AF is assignable to a custom button and works in both AF-S and AF-C modes. In continuous AF, holding the button keeps focus on the nearest eye to your selected AF area, useful for portrait work with subject movement.

How long will the battery last on a full charge?

Roughly 290 shots through the viewfinder or 340 through the LCD per NP-FW50 battery (CIPA standard). For video, expect about 50 minutes continuous recording. The camera ships with two batteries, and you can charge via USB or external power source-a feature that lets you power the camera indefinitely for time-lapse work.

Does the a7R II have a touchscreen?

No. The 3-inch tilting LCD (1,228,800 dots) is not touch-sensitive, though it tilts up roughly 107 degrees and down 41 degrees for low and high-angle framing.
