why 40? that's 40 on FF and 65 on crop. huh?
and what are you going to use it on? consumer DSLRs have that ugly prism/flash thing protruding from the body and a pancake would look real ugly on them
a 5D or 1D is so large that a 50/1.8 already looks like a pancake (i.e. no advantage using an even smaller lens)
why 2.8? I understand the 24 and 28, they have IS, they are wide angle. but 40 is in the "normal" range, f/2 would help. even if not the best quality, who cares.
I hope that this is going to be cheap at least.
Unless they are actually planning a EOS-mount mirrorless camera like the new pentax thing. (uhhgly) so a pancake would make sense. still, 30/35 would have been better.
Seems very similar to the existing Pentax 40mm 2.8 limated pancake thats been sold for use on DSLR's not much smaller than a 5D.
The prism and the grip still don't add that much more lenght to a 5D beyond the mount so a slim 40mm 2.8 will potentially save space, the same with most Canon DSLR's.
