After much research and a number of tests, this bag is the best that I could find! It holds in its main pocket, my EOS 650D with grip and 18-135 mounted my 50mm f / 1.8, and one or another object (or a single telephoto) and my flash. On the flap of the main pocket, two memory card inserts avoid losing them in larger pockets. The bag "tote" serve me carry my protectors filters and possibly a booster housing (it is really VERY large). Little more, the protective cover against rain integrated and the flap to transport tripod. Remove the unit, leaving the bag on one shoulder is very easy. Yes, the bag is slightly bulky, but my case, my goals, my flash and all my accessories are well protected.
