I'm sort of wondering the same thing. Some people seem to advocate backpacks but the idea doesn't seem right to me. I thought I'd found the perfect bag at the local luggage shop but it's only 24" long and it won't fit. It's a sports bag. Not a real big one that you could fit half your life in but if it had been a little longer it would have been perfect IMHO. Nice shoulder strap. Side pockets big enough for film holders etc. The main pouch big enough for a tripod and camera. I figured I would line the main pouch with foam but I guess I could just wrap the camera etc up in bubble wrap.
congrats and welcome to the dark slide! Pun intended http://apug.org/forum/html/emoticons/biggrin.gif Did you get a field camera or a monorail? I go without a case / bag and prefer to just leave my 4x5 on the tripod (asking for trouble) and cary a small gear bag with my lenses and holders / loupe, focus cloth, bandaids, etc.
If the arthritis necessitates something with wheels, f/64 makes some nice lightweight suitcase-style hard cases with wheels and a handle built in. B&H often has them in the used section--not actually used but overstock or demo models. They also make some nice backpacks suited to LF.
For my 8x10" Gowland, which is ultralight and packs thin, I use an ordinary knapsack designed for laptop computers.
For my folding 4x5", right now I'm using a padded shoulder bag that seems designed to carry a laptop and a printer. I've been looking, though, at a Domke F-802E reporter's satchel, which looks nicely laid out for my setup, with two wide pockets on the outside that should hold two Grafmatics each. When I last checked at B&H it was out of stock, but I'll check back.
There are several bags on the market with wheels. THey look like the pull on luggage seen all over the world. One can configure the internal spacing as you wish. Well padded .THey are not cheap. I have one for my 35 mm equipment, but have been thinking about switching out all systems to this type bag , as I am not as strong as I use to be (aging and arthritis too; which doesn't make my ego happy http://apug.org/forum/html/emoticons/smile.gif).
I've got a relativly small Kelty day-pack that fits my 4x5 and extra lens, several film holders, filters, cable, cloth, etc. It's a normal pack for backpacking, but I really like it (of course, I do a lot of day hiking when I shoot tho...). I always take it with me as a carry-on when I fly (several times a year, fits nicely under the seat, never really tried putting it in the overhead bins for fear of it getting squashed by everyone bringing their roller bags on that I can't imagine fit the maximum size allowed), and have never had a problem with it. To me, it's super light, and even has a waist belt strap thingy on it for heavier loads. No wheels, but I'm usually shooting in places that I think wheels wouldn't survive the trip or help you out very much. Also, in some places like certain wilderness areas you can't bring wheeled things in, including carts/bags with wheels.
I have a Lowepro S&F Rover Lite. Doesn't seem like much, but it takes:
Linhof Color 4x5
6 lenses on lensboards (90,120,135,150,210,360mm)
Gossen SBC meter
6 film holders
2 boxes of film + an empty one for exposed sheets
Polaroid holder, 10 sheets polaroid (not the box)
Dark cloth (T-shirt)
3/4 liter thermos of coffee
What more do you need?
I want one those Lowepro Trekker AW's. I was with a fellow this summer and he had one. It has the ability to open in the front. My old bag is a top load and everythng I need is always at the bottom and requires emptying it every time it seems.
