I have been shooting with the all-metal Canham JMC 10x8 camera for about 7 months now. While I absolutely love the slow, methodical working process and the detail from shooting with the big camera, I'm not sure how much I like the camera itself. It bothers me that it doesn't seem as stiff as it should be. The rear standard, especially, seems to sway towards the front and back pretty easily, as in when inserting a film holder, etc. I have not been unhappy with the results, but have noticed a few random negatives that don't seem as sharp as they should be, and I always focus carefully with a loupe and I use a huge gitzo tripod with majestic geared head. I guess what I am asking is this: to people who have used or seen the canham, how does it compare to other 10x8 portable cameras? I'm not interested in a wood field, but other cameras I was considering are the arca swiss f-metric and the toyo 810mII. I shoot mostly in the field, but usually not far from the car. I don't mind a camera that weighs more than the canham, but I want to feel confident in the camera's stability. However a full studio monorail would be too big. To a lesser extent, I would also be happy if the movements were a bit more precise, but mostly it's stiffness I'm interested in. I've never used any other 10x8 cameras, so maybe all of them are similar and I should just stop complaining and keep the canham. I shoot mostly color fine art work, portraits, suburban landscapes, etc. Any help would be greatly appreciated.
