44 x 33 medium format: what each focal length frames

Every camera on this page has a 0.79x crop factor, so whatever the brand, a lens frames like its focal length times 0.79x on full frame. A 50 mm lens frames like 40 mm on full frame on all 5 of them.

To see any of these focal lengths live, Prospekt (Lens Simulator: Prospekt on the App Store) turns your iPhone into a viewfinder for your camera body: pick the body and a focal length from 14 to 300 mm, point the phone, and the screen frames what that lens would. iPhone app, $3.99 once, no subscription.
