Interesting read, and interesting to read everyone's thoughts and experiences on these different cameras!
How about Z Cam? A huge, huge range of resolutions, crop modes, no crop modes, codecs, frame rates. ProRes in camera.
The noise is very good, and the dynamic range is very good.
Mounts - lots of changeable mounts - EF, PL, MFT, E and I think more.
It depends on which model you go for, but all of the main range could suit budgets and deliver a body that is modular, buildable and a great image. I have the F6, and while getting a kit together to make it usable cost about 5,000 (4200 ex VAT) I'm sure making a DSLR style body more filmable would cost similar. Or does it?
Thanks again!
