Thanks. I was wondering about lenses. I couldn't see which ones cropped the sensor to a smaller format and which didn't.
The thing that attracted me was the high (50 mp equivalent) resolution, which according to a well known pro over here is medium format worthy. He printed a shot at 80x53" and said it easily matched a 50 MP medium format.
No DoF preview wouldn't worry me, I never use it. Or am I missing a deeper point here?
My use would be landscapes and aerial, and 1/4000 would be ok for aerial.
I say this not to argue in any way, just to say what my use would be. Most cameras are a compromise in some area.
I think I spotted that one doesn't want to go over 400 ISO. That may be a limit as on a dull day I need to push the ISO to maintain the shutter speed for aerial work. Having said that, in WA there's rarely a day when this would affect me :-).
Also sigma software is too slow so it's best to get ding files out to use anywhere, and these are large.
