Harperc, Here's one of several packs I've used. This one is probably 15 years old and has only been out on one trip in the Adirondacks back in the 90's. The rest of the time it's been a closet decoration.
It is a LowePro (model # unknown) that was quite comfortable when fully loaded considering the weight. I used to carry 2 camera body's (Nikon F3's), 3 to 7 lenses from 20mm to 300mm, plus a collection of filters, flash gear, reflectors, macro ext. tubes, motor drive and other stuff. I would then strap several pouches and cases with bigger lenses and tripods plus camping gear to the outside. The up-side to having all this gear was that it was available to use in the boonie's and not back on the table at home. The down-side to having all that gear was that one must carry it.
There are a couple more divider panels not in the pictures and there is a rain fly attached and tucked into a pocket on the bottom. There are no rips, tears or abrasions in any of the fabric that I could see this morning.
PM me and we'll work something out if you're interested.
Pete
