Hmm. I'm really liking the EOS-M with 90EX acting as master and 580EX II off-camera as slave. What would be a good bag, not too big, that will fit EOS-M, EF-M 22mm, 90EX, and 580EX II?
The 580 pretty much screws the "not too big" bag selection. How about carrying your flash in a pouch on your belt? Think Tank and Lowepro make some nice ones.
Digging through my closet, I found an old "M Gear" bag that used to be too small for DSLR but perfect for EOS-M + 580EX II. In the spirit of bargain-priced EOS-M, I shall refrain from buying yet another bag
