Given that there is a 22 a 22mm & a 28mm already isn't it somewhat ridiculous that the next prime available in EF-M could be a 32mm.

Surely a 50-60mm f/2 (IS, maybe) to pair up with the 22 f/2 would make for a more balanced approach.

I'm with you on that. A 50ish prime would also pair nicely with the 11-22 zoom. On the other hand, there is already the 50 f1.8, which can be adapted, and some people who post here feel quite strongly that the 28mm f3.5 doesn't meet the need for a fast normal prime. Then there are those who feel the need for lots of fast primes of unspecified focal length and resent Canon's failure to provide them.

I think they're both pretty important. Obviously, 50mm equivalent is a key FL.

And, the 50-60 would be your 85mm equivalent, so that

*is* an important FL, with the benefit of the 50mm optical formula that's very space efficient (ie we can have a small, fast, EFM prime). Just look at the glass size of the first and last elements on a 50/1.8, and imagine that without all the plastic around it and a narrower barrel -- then reduce the diameter!

I'm suppose the Canon approach is to start wide, and work towards tele, and my only guess is that Canon thinks that a big chunk of the EF-M crowd prefers zooms, so those primes are a lower priority.
