I have an OM-D with the 12-50 telephoto lens almost always mounted on it. I also have three other lenses (and adding more) plus I have the flash and cables. I also have an XZ-1 with an extension tube on it (basically making it look like another "SLR". I've been looking at the Tamrac bags and they look pretty good. But there are TOO MANY to choose from! Any advice?
