I'm looking to buy an 8x10 for street portraits, but I don't want any movements at all -- I just want to throw it on the tripod and shoot. No rise, no fall, no shift, no tilt, no nothing. I want to reduce the amount of time from unloading out of car, until I'm shooting the first frame, to a very short time. I want to shoot full length or tighter, with a 300 or 360. I'd love to never worry about the front standard EVER getting out of parallel with the rear standard. I just wanna shoot pictures. Is there such a camera. I've owned Deardorff 8x10 and it's just too inaccurate to set up quickly, in the field. What about the Wehman? Or is there something even more simple? Thank you.
