My wife has a T4 Super (they don't make this one anymore--the one with the Zeiss 35/3.5 Tessar), and you can use it high up with the angle finder, if that's what you had in mind, but the finder is quite small, so it's not so easy to see what's going on in the finder if you're up much higher than arm's length.

I like shooting overhead with a medium format camera and a waist level finder, as in this shot (Bronica S2A, Nikkor 50/3.5, f:3.5, 1/15 sec., TX, EI 800, Acufine)--
