I use a 35 2.0 IS on my 70D and have and M/22. A 50mm "M" lens would complete my package and make my EOS M a complete kit for travel. I like 50 a lot for portraits.A 50mm "M" lens would solve all of my problems.What propblems?? 50mm is too long for general use and too short for portrait. How does it solve your problem??
And I think that would solve my GAS problem since I think I'd prefer an M/22 & 50 to the G7X or any other compact.
