Hi all
I know that carting around your 4x5 (etc.) gear can sometimes be a real PITA so I thought I'd share my success with finding a backpack that fulfills my needs beautifully (and comfortably too)!
The Mountainsmith Paragon camera daypack
In the top (padded compartment) I can carry my Shen-Hao, 3 lf lenses mounted on boards, meter, loupe, plus my dSLR with short zoom attached as well as a telephoto lens. In the bottom compartment (not padded) I can carry a Fuji quickload film box with a few film packets and the film holder, a 6x12 roll film holder, 3 regular sheet film holders and my dark cloth. The various other pockets hold my filter wallet, notepad, lens cleaning cloth as well as other essential gear. Handy to note are the side mesh pockets (perfect for a water bottle) and the two zippered pockets on the waist strap where I carry my car keys without fear of loosing them in the field. I strap my tripod to the front via bungee cords (not included which is my only gripe about the bag).
It is sooo much more comfortable than my Lowe Pro Photo Trekker AW II (which I'm selling by the way), lighter and cheaper too.
Oh, and I can personally recommend Snow Leapord if you want to buy one. Their customer service is just great!
