On the list of obscure cameras is this 35 mm half frame rotary shutter Mercury. The aluminum body tends not to age well.

I think the Olympus PEN series has the same. From what I gathered, it's still a focal-plane shutter, but instead of a pair of curtains that follow one another, it's something that literally rotates to expose the film. And I take it the speed of the rotation determines the exposure time (or, inversely, the shutter "speed").

I used to have a Super D with a 58 mm f1.4 and a 135 f4. Built like a brick, I liked this camera better than Nikon I replaced it with but the availability of lenses and accessories in 1983 even in L.A. was poor. Franks Camera in LA were the only ones that had any Topcon gear.

Actually, they're two different things. Not that I grasp it that well.

It's basically a rotary analogue of Leica's curtain shutter. Here's it's two metal disks (hence the arc on top of the camera). The first one starts to move. Then with the gap varying depending on shutter speed, the second starts to move.
