A few nice dodge camper van images I found:
6. Free Willie (Front)
Image by 12th St David
Mamiya C3
Mamiya-Sekor 105mm
Fuji Pro 160S
f5.6 1/60
I note that this is not as sharp as some other shots, especially the far side of the bus. I think that’s due, at least in part, to the slowish shutter speed. According to the old reciprocal rule, with a 105mm lens, I should not go slower than 1/100th for handheld shots.
Also, the bus is just so big, and I was relatively close, so at f5.6, there might not have been enough depth of field to get everything in focus.
