hdcamteam spotted a curious detail about the Canon EOS M. Before releasing the EOS M to the general public, Canon removed the 3x-10x digital zoom from the firmware. This feature was available with the Rebel T3i/EOS 600D and is no longer available on the Rebel T4i/650D. The digital zoom feature was available only for video mode, same on the Canon EOS M (price & specs). Among other reviews on the web, this is confirmed by dpreviews hands-on preview on a pre-production model (still online here), see image below.
Reason for the removal? Who knows. What do you think?
