I currently have the Lowenpro Flipside 300. At first, it was a perfect bag, which fit everything. I had a T2i body, 18-55 w/hood, 100mmm macro w/hood, 85mm w/hood, 420ex flash, and some misc wires, cleaners, etc.
I recently bought the 7d, 16-35L w/hood, 28-70L w/hood, 580 ex II, and will also be carrying the 100mm w/hood, 85mm w/hood. It fits everything tightly, with the exception of the 28-70 hood, which probably can fit if I force it in slot, but I would expect it to break eventually doing so.
I will be planning to get a battery grip and a 50mm 1.4 w/hood, and a 70-200L IS II. I was wondering if anyone knows of a decent size backpack that will carry my gear?
