I took this bag to complement my backpack mode output for 'slight' or the SLR, an objective and a backup battery. For that it is perfect and everything goes perfectly, for cons I have a doubt as to the zipper that is in the bag above, I anyway lest it eventually scratch the surface, this is someone has already had the problem? So I put the screen down reflex and is the top of the lens, so the cap, which comes into contact with the device, which is much less disquieting. Too bad, otherwise it was perfect
