GMCPhotographics said: I'm surprised that Canon haven't announced a range of pancake primes for Rf mount yet...those would be a sweet addition to the Rf mount. It's a lens design very much suited to the benefits of the Mirror-less mount Click to expand...

First, I think that some portion of EF-M bodies are sold to people heretofore using EF FF SLRs, and Canon wants such people to continue buying EF-M bodies even after switching to much more compact RF MILFFs. If they had pancakes available for the RF, that would tend to allow people to do without an EF-M body entirely going forward. Likewise, if RF cameras could mount EF-M lenses, you may choose to forego an EF-M body. (In fact they made the RF film-flange distance 2mm longer than EF-M. I can't think of why, except to keep you from doing this.) If I'm wrong, we'll see a truly compact RF lens or two soon. But my guess is not. (The 35/1.8 is pretty big for a mirrorless 35mm of modest aperture, thx to IS and macro capability.)Second, I don't think a pancake is an ideal size when the handgrip already extends past the body front as far as it does. For practical purposes, a pancake doesn't make the camera any less deep than a lens sticking out as far as that handgrip. Further, I have no interest in a pancake lens with f/2.8, which would be perhaps portable at times, but bring no extra capability when you have your trinity zooms at hand. Any small portable lens should still expand the envelope in some interesting way, optically, so I'd be much more interested in a 50/1.8, 35/2, 28/2 or some such.In the meantime I'm using a Leica 35/1.4 ASPH on the R and have taken more shots with it than with the RF lenses, since I always have the R and Leica lens with me.
