Leaked specs from the internet (assuming true COULD BE WRONG).
- All-new sensor with no anti-aliasing filter and Expeed 4 image processing engine. A lot can be done with sensor design and not just noise: sharpness could improve too. The sensor in the D800/D800E is at least two if not three years old; a newfangled Sony sensor could be hot.
- Higher resolution 1229K dot rear LCD. Presumably the ugly mangled Live View is fixed, but that is to be seen. Where is the Apple-style Retina display though?
- ISO from 32 to 51200 (ISO 32 particularly interesting... I’ve long lusted after ultra high quality low ISO, but it seems to be the the usual Nikon “Lo” mode non-ISO one nominal stop below a true base ISO of 64).
- Electronic first curtain shutter for ZERO VIBRATION exposure mode in Live View (Canon already has this in the 5D Mark III). Maybe Sony can take a lesson here. A zero vibration shutter is a big deal for super teles and high magnification macro work.
- Still no 4K video., but 50/60p video.
- Quieter stronger shutter with kevlar good for 200K cycles.
- (glaring omission) Apparently no EVF or even EVF option. Quaint.
- Same focusing system as Nikon D4S: multi-cam 51- point. Configurable in 9/21/51-point coverage settings. AF points clustered towards the centre of the frame; so DX offers nearly 100% coverage.
- Faster frame rates.
A nice upgrade, but disappointing for the lack of an EVF, my #1 wish.
Still, practical featurs hold promise: a sensor delivering 14-bit images that is as good or perhaps better than the Sony A7R sensor (see limitations) will be welcome, as will the vibration-free EFC shutter and (hopefully) improved Live View.
