Yup, more pancakes would be nice.
I don't see the point of a CSC without them. Would be good to see canon follow Pentax's lead.
What focal length pancakes? Fast UWA prime? Short Tele?
I've actually rediscovered 35mm equivalent as a nice perspective, in my early days I was eager for drama and perspective, so pooh pooh'd boring established FL's like 35. But it's nice. Especially with the fast aperture.
I like my 22 EF-m a lot.
And I WAS kidding about the other stuff.
35mm is a great focal length, and the reason why I like the M/22mm combination for a compact walkaround. I'm actually more partial to the 35mm focal length than the standard 50mm.
