I have a Canon Rebel T3i and an extended battery pack I want to keep on my camera. I tug and tug and tug to get it out of my current bag. (Some reason it goes in easily) A case logic, with a top opening to slide in the camera lens for separate keeping with my base. I typically keep a 18-200mm as my walk around lens, and would love to keep that attached as well. It's pretty much impossible to see if any cameras have battery packs on, in images provided while I online bag shop. Any bag I buy MUST be zip shut to keep out dust and dirt! Thank You!
