My problem is with the look of this camera and the feel which will obviously result somehow from that look. As others already mentioned, this is FF and once you use FF lenses, especially telecoms, then it becomes immediately important how easy such a camera can be held and operated. The Leica S has that, the Leica R8 and R9 had it, as well as the Leicaflex SL from 1960's. So Leica definitely knows how to build ergonomic and also good looking cameras!
And now this??? This is why I am upset. And this could have been the differentiator for me against Sony and their FE line of cameras. Which would mean much more to me than having the greatest and latest sensor with most MP and most AF points - I actually do not care so much.
So I was actually expecting a kind of a mini S, maybe if the wanted to do something nostalgic give it a bit more the look of a mini S on Leicaflex SL steroids. But not another tiny body with obviously tiny battery and hence short battery life.
But maybe I am just wrong and the new camera turns out to be the all singing and dancing queen and handles even superbly albeit the look we have so far, but my hope is not high ....
