Sony ups the ante with the A7RVI and FE 100-400mm f/4.5 GM OSS

[AlanF]

Sony has officially announced the 66.8MP back-illuminated stacked sensor A7R and their new telephoto lens 100-400mm f/4.5 lens. The lens weighs in at 1.84 kg, which will be about 2 kg with hood. I would be using such a lens most of the time with a 2xTC on it to give a 200-800mm f/9, which would be heavier than the RF 200-800mm f/6.3-f/9, and narrower through the shorter focal lengths.

That's a truly remarkable camera with a lot of possibilities, from landscape t wildlife to portraits and fashion.

I wonder if it will kill some of the Alpha 1 II sales?

Maybe, the main difference is the rolling shutter speed: 19.6ms versus 3.8ms for the A1 II (versus 6.3ms for the R5 Mk II).

Jan Wegener, one of the much better YouTubers, has done a review. https://www.youtube.com/watch?v=KNZJjKR0LeI
The main problem is that the detail of the images starts to drop at isos greater than 1600, and is significantly down at iso 6400.

The 100-400/4.5 is pretty long. Slightly longer than the RF 200-800 fully retracted, and some 4.5-5" longer than the RF 100-500.

More info. Rolling shutter, readout time appears to be about 20 µs, more than 3x slower than the 6.3 µs of the R5ii and slower than the good old R5's 16..3 µs.
