The shift/rise is only up like a Roundshot, the cameras are similar. They're set up to shoot 120/220 and 70mm, 70mm doesn't work well because the cassettes don't sit properly in the mag. 120 is hopeless so the only real choice is 220. My camera was modified and had a full speed range from 1/250s down to 1s. It shot significantly better than an unmodified camera but was still not a good as a Roundshot 65. The Alpa has reflex viewing.
