I'm even thinking about taking ONLY my EOS M next trip
Been there, done that. Will NOT do this again. Japan in June/July: I had the 22, and th3 nice small zoom, as well as samyang 14/2.8 and nikkor 50mm 1.4.
All great.. wonderful night shots.. but for general street shooting, I missed way too many opportunities.
As a second body, sure, but never again as the sole option. During the last few days I was so frustrated that I kept thinking of going to yodobasi and picking up a kiss/rebel to hold me over.
