AF performance remains much like the A7: fast enough under most situations, but slowing noticeably when the light level drops, or with a slower lens. Accuracy is fine when there’s enough light, but again – when it gets darker, you’d better get a second shot for insurance. The camera has a tendency to pick a different distance every time you refocus, especially if the background and foreground distances aren’t that different. It has PDAF pixels on the sensor, but the reality is it still won’t track as well as a traditional DSLR. There are pre-focusing options as well as eye-sensor triggered AF start, but they don’t really speed things up that much and have quite a noticeable effect on battery life. Viewfinder and LCD refresh rates are both fast enough for most uses, but you might be aware of some lag if you’re shooting rapidly moving objects. On the subject of the EVF – both monitor and LCD use OLEDs; there’s nothing wrong with the panels themselves, but the optics used for the EVF could be better; a bit more magnification would help, and there’s too much distortion unless your eye is dead center. It’s not as bad as the GH3’s EVF, but nowhere near as good as the E-M1 or X-T1, either.
.....
No matter how much technology is packed into the rest of the camera, if the sensor does not deliver – then we might as well go home. I am still not happy with the crippling 11+7 bit raw compression: you can still run into posterization fairly easily in highlights and shadows, especially if adjusting color balance under mixed lighting. Watch carefully for clipping, too – it doesn’t roll off nicely in the highlights like the D810. ISO for ISO, lens for lens, the D750 delivers a better quality file – with about 1-1.5 additional stops of usable (i.e. clean, manipulable in postprocessing without artifacts) dynamic range – in addition to slightly more transparent color, and surprisingly, about a stop less noise. There seems to be a little more ‘bite’ in the A7II’s files, though – I don’t know if this is because Nikon is cooking their raw files to have less noise at the cost of fine detail, or whether Sony is presharpening with no NR, or whether the AA filter in the Sony is simply a bit weaker. Or perhaps it’s a combination of all three.

Браво на Sony, че се намесиха в пазара, иначе още щяха да не правят на луди и да ни продават фул фрйми по 5000 парчето
