so - in the end of the day, if it is not the camera that's to blame (I still do..), but me, and the students, what camera(s) in medium format would you recommend?
Mamiya Press or Super 23's! Built like brick shit houses, swapable lenses. Ok, so it isn't an slr, but so what, parrallax correction is a usefull thing to learn about! So is filter compensation! Students won't be able to break them, not easily at least, students will learn more by using them. Get 2 or 3 6x7 backs for them, they can shoot 6x7 or 6x6 or 6x4.5 all on one back if you have the masks for the backs. For that matter you can also get some 4.5x4.5 masks for them, then they can make super slides!
