Hi Folks! Just after some suggestions for a new camera kit bag. I am currently using a Lowepro AW100 and it's bit of a tight squeeze for all the kit. The new bag will need to hold the following : DSLR, 17-70, 75-300, 100 macro and 50mm prime lenses, external flash, plus pockets for flash cards, filters, etc. Don't want to spend more than £50 really. Any suggestions? Crumpler perhaps?
