design flaws? I don't know if I would call them flaws, but the way the camera works is a little bit different than most other field cameras.
One thing i've found handy, is when adjusting front swing, I don't loosen the front standard all the way, I make it just loose enough so that I can nudge it to rotate the standard with my thumb (using a bit of pressure), but not loose enough so that it is easily moved by accident. This makes adjusting swing for very fine adjustments quite easy, without adjusting shift in the process. I usually set my front shift (if needed) with the standard loose, then tighten down the standard until it's starting to get snug, then I can nudge the standard with my thumbs to adjust swing. Sometimes I tighten the standard down farther after I've made my adjustments, but usually I just leave it like it is, cocking the shutter never moves the standard when it's lightly snug, at least it hasn't for me.
Rear standard adjustment (for swing/shift) is a little tricky (or different, maybe is a more accurate description) compared to other camera designs. I don't have any tips on using this, once you've used it a few times, you'll get a feel for how it moves.
I've also found that when switching from a wide lens to a longer lens, you don't always need to re-position the front standard into a screw hole farther out. The focusing knob can move the standard out a good ways, this may save you some time when switching lenses, if you know you don't need to un-screw and re-position the front standard when switching between certain lenses. Depends on how much of a jump in focal length you're making.
Also, I keep a small allen wrench with me (1.5mm I believe?) incase some of the small allen nuts get to loose or are to tight. Particularly on the thumb latches that stop the rear standard's tilting to 90 degrees, and the front standard's tilting. When I first got the camera those thumb latches were to tight to move comfortably, but then after making them more loose, they were to loose after a while. So I found a happy medium later on. But I keep that allen wrench with me, just in case they get to loose again (they haven't so far). I always try to keep at least a small allen wrench, small phillips & flathead screwdrivers with me when shooting though (with any camera), you never know what might need some tightening
Good luck, enjoy! It's a great camera!
