This will hold a 70-200, or 17-55 plus a some snacks, or any combination of similar-sized stuff. The bottom zips up so you can fit larger stuff into it, if needed. Bag is as new and unused. Bought because I thought I was going to be doing a lot of running around, but turns out I didn't, so I stuck with my Urban Disguise. Great
Shown next to 70-200 for comparison (70-200 is, alas, not included).
