Here's my bag. Some Promaster model. Cheap but very roomy.
20D on the left
17-40L
50 f/1.4
Elan 7NE, soon to be EOS 3
580EX
35mm 100 T-Max B&W film
My girlfriend has my 10D and 28-135 but that usually resided next to the 17-40. When receive my 85 f/1.8, that'll have to bunk with the 50mm lens.
On top there is my remote timer and switch TC-80N3
On the bottom I have a red, yellow, and polarizing filter in 77mm thread. 58mm warming ciruclar polarizer. Cleaning fluid and a lint-free micorfiber wipe cloth.
Isn't it funny how saturated the colors are from the point and shoots? This one is the Canon PowerShot S400
