Hi, I'm sorry if this is the wrong place to post this. I do a lot of hiking and carry with me my t2I along with a 100-400, 24-70, and 100mm macro. All cannon lenses. I was wondering what the best belt or harness would be best for carrying the different lenses. I have a slingback but that doesn't really allow for quick changes. The 100-400 came with a nice belt case but I don't have anything for the other lenses. If I went with a lowe pro utility type belt would my canon case that I do have work with that or would I need the belt with 3 or 4 new cases to attach to it? Id appreciate any help!
