Speed has received a major boost with a 40% increase in speed over its predecessor. The AF system received its own massive upgrade with the use of 399 phase-detect points and 25 contrast-detect points for a speedy Fast Hybrid AF system which will offer extremely accurate tracking. The phase-detection points even extend to A-mount lenses when used with the LA-EA1 and LA-EA3 adapter.
Designed to last, the updated magnesium alloy body has improved weather sealing and a robust lens mount for working with large lenses. Also, the shutter has a reduced-vibration design, cutting down shutter vibrations by about 50%. Also, it now uses an electronic front curtain shutter and is rated for 500,000 cycles. Silent shooting is also available for a quiet shooting experience when needed.
Onto video, the major addition is internal UHD 4K 3840 x 2160p recording at 30 or 24 fps with the XAVC S format at 100 Mbps. This is possible using either the Super 35 crop mode, with no pixel binning, or the full-frame readout. Full HD 1920 x 1080p is still readily available at up to 60 fps and HD 1280 x 720p is possible at up to 120 fps. Additionally, the a7RII benefits from the inclusion of the S-Log2 Gamma and S-Gamut settings as well as fully customizable picture profiles.
Composing and reviewing your images as you work is handled with either the 0.5" 2.36M-dot XGA OLED Tru-Finder electronic viewfinder or the 3.0" 1,228.8k-dot tilting LCD monitor. The viewfinder offers 0.78x magnification and a 4-lens system with double-sided aspherical elements for comfortable viewing. The monitor helps in odd positions by tilting up 107° and down 41°. And, to stay connected, the a7RII packs in Wi-Fi connectivity with NFC for remote operation and transfer of images to a smartphone, tablet, or computer.
