Sony 42.4MP Full-frame A7R mkii 4K capable Digital Camera (Body).

Description

The camera can capture 4K (UHD) video at 30p/25p or 24p in the XAVC S 4K format. The 4K video can be taken either from the full sensor width or from a Super 35 crop. Even this smaller crop over-samples by around 1.4x. The a7R II also gains 5-axis image stabilization that is rated at 4.5 stops, according to CIPA standard.
Sony says the on-sensor phase-detection AF can be used with A-mount lenses using the simpler LA-E3 adapter, rather than the LA-E4 that had an SLT mechanism built in. At the press launch in New York we even got a glimpse of the a7R II autofocusing Canon EF lenses using a Metabones electronic adapter. Focus appeared to be on par with OVF focus on a native Canon body, and the AF experience itself didn’t appear to be limited simply because you’re using a third party lens (full coverage and tracking are available).
On-sensor phase detection elements cover 45% of the sensor, which may sound small but actually translates to around 67% coverage in each direction. While this is some way behind level of coverage offered on Samsung’s NX1 (or even Sony’s APS-C cameras), it’s still a considerably larger area than that covered by any full frame DSLR’s focus sensor.
It also gains an electronic first curtain shutter option to eliminate shutter vibration, which was a problem with the original a7R at longer focal lengths. It also offers a fully electronic silent shutter.
