Cool, how about image quality, any change?
Higher iso is slightly better, file depth is slightly better, file size is much better, tethering is much better, lcd much better, menus 1 million times better, focus is better, more solid feel etc.
You can set in camera parameters even black and white. The black and white function is very cool.
Tethering, even usb is much improved. The Canon software is somewhat disjointed, but will do about everything that any software does, it just takes a new learning curve.
the preview time is fast. I saw reports where everybody said it was about 7 seconds for a raw file to preview but I see it in less than 1/2 of that in OSX.
The one standout is the viewfinder. For once manual focus is actually easy on this camera.
I put the 4:3 mask in and the viewfinder is still big.
File look is different than my phase backs, probably because of the AA filter. It starts out softer, though sharpens ok, though it's just different. Not bad different, just different.
It may be my imagination, but the camera seems just slightly smaller than the 1ds2 or slightly more compact. Other than the Leica, I'm not that wild about small cameras.
Given all of this it is the very well built camera and in a lot of ways reminds me of that robust feel of the contax, where it's solid and rattle free.
Regardless, if I could have a p back, especially the p21 that went to 800 iso clean, I would have gone that direction.
The Canons are interesting in that some people love them, some are the opposite, but nobody can dismiss how much of an impact they have on professional photography.
I wouldn't say it produces the best file in the world, (that's very subjective), but it is a very versitile camera.
