For years I've made do with an old camera bag that was "The" bag...25 years ago but despite the faded appearance, downright ragged look and relatively small size I couldn't bring myself to part from it simply because I was unable to find anything functional yet affordable that came closs. Recently I changed camera's and purchased a few new items which meant I had to break down and purhcase a new bag - the other was simply unable to fit the new camera with grap plus lens.
I started out buying a Tamrac messenger 7 thinking it would work - I only have three lens, the camera plus grip and the typically assorted misc. Unfortunately, as soon as it arrived it became obvious the Tamrac was not meant for a camera with grip attached. I fiddled with the inserts every way possible to no avail - the fit was bulky at best and left me fearful of an inadvertent breakage.
Trying to make it work I purchased a "fanny pack" to switch all the accessories to plus a couple of lens packs/case to provide extra cushion. While both were a good deal and provided the protection I needed the entire situation was gettting out of hand - too much to keep up with and difficult to access.
Finally, I decided to try out this Lowepro...great choice! It provides much more protection than the Tamrac bag, is easy to access, actually fits my camera - with grip, 3 lens (1 zoom, 2 prime) plus assorted misc. Easy to organize, easy to carry, easy to access and easy on the budget.
Wish I had bought this one first. Actually has a little room to grow if needed - or just enough space to put in a few extras without having to wrestle every time you access the camera or want to change a lens. All in all an excellent value!
