Re: Anyone planning to use EF-S Lenses?
 

I also find the IS of the 17-55 exceptional. I am a very bad hadnhelder, but with this lens I have shot hand held for hours with excellent results.

The problem is that Canon's APS size sensor (as in 7D) is smaller than other manufacturers. It will be ironic but Nikon's DX lenses may not vignette as bad as Canon's EF-S lenses.

Anyway I hope both will understand that AF(or at least motorized wireless focus), IS, servo zoom, should be given even for the cinema pro lenses.
