Hello. I have tons of bags, but for small day trips and family I am tired of lugging around my different big backpacks when I only want to carry my 5d or my 7d with a 24-70. I am looking for a small bag i can wear around my shoulder where I can heavy easy access to the camera. What are the bags big enough to hold a 5d or a 7d with a 24-70 (with its hood in reverse)? Thanks.
