I have been searching everywhere for the perfect stealth canvas bag. Loved the Crumplers but longed for a zipper and something for MUCH less cost. I wanted that worn canvas look, soft yet sturdy, so I decided to go to my local Army/Navy store and WOW... Plenty of opportunities for awesome bags. Inexpensive too!
Found this insert on Amazon for $28. It's called the DSLR Paddy by BB Bags; The zippered heavy canvas bag from the army/navy store cost about about $20. It was a perfect fit. Holds 7d with 50mm on, and room for at least 3 more lenses. Big outside zippered pockets hold flash and misc gear. Side pockets for phone, wallet and keys too!
So, for about 1/3 the price of a Crumpler or similar, I have something really soft, very protective and comfortable to wear. No logos, total stealth. Very happy! It also has a slit pocket on the reverse that will carry my Ipad. The whole thing together is about the size of the 7 Million. Maybe even a bit smaller.
