I've got a small Tamarac (bought at "Ace" - see link above) for MF, but now with LF 4X5, it "works" but I have to carry the tripod and geared head separately. Basically, if I load the car and don't go far, it's fine. But the car has a shopping bag of other stuff. So I need more space and would love away to attach a tripod + head. I'm liking the bags that have a waist strap as that helps shift weight off the shoulders. The real answer is to carry less... duh. I do that when I'm shooting. Even replaced the shopping bag with another camera shoulder bag... bought used but almost new condition. It's the tripod carry that I"d love to solve to free up my hands.,
So what Alan says about the F64 bags rings a bell... they look old and without much of a frame to even the load. I'm resisting that option. My small bag is fine. It's the 4X5 + tripod thing I"m trying to solve.
FWIW, I think "urban landscape photography" is under appreciated. Living in a picturesque town offers lots of possibilities, and I can see this.... so some of my photo hikes are 'round the burb. Yet much the same needs apply. Civilized carry perhaps if you will: Don't need to carry food, or water or clothes.... just my gear.I'll get it figured soon enough maybe. Or at least get another bag that gets closer to the right one.
