Nikon made a 750 exposure back, too. It takes a full 100 foot roll.
Thanks for all the comments everyone. I reckon I'll be keeping this one and running a role of film through it at some point soon.
It's a heavy lump of metal though. I can't see myself carrying it around on a regular basis.
Those things are built tough - and they leave quite a mark when dropped on one's foot. :o
I kind of like the mechanical-age construction of the Topcon bodies; it inspires confidence, and feels like it might also damp mirror vibrations. You do have to be careful not to get sucked into the camera's gravity well, though.
The only thing I did notice, is that that rewind lever is a bit wobbly (up and down). It is very smooth and seems to function well, but I'm wondering whether this is a potential problem?
Be careful when buying lens, Topcon made 2 lines of cameras, the RE 2 used the same lens mount as the Super D (a side note the Super D was used the Navy for a few years in the 70s) and a consumer level with leaf mount shutters, the lens are not interchangable.
There are lenses for early Topcons like Topcon B 'Auto Topcor'
There are lenses for the RE Super/Super D and RE-2/D-1 'RE Auto Topcor'
There are lenses with leaf shutters for Auto 100/Unirex 'UV Topcor'
The Topcons were/are great cameras and deserve more recognition than they get.
