Diaphragm is intact

and you're in the market for a 25mm viewfinder

but shutter speeds are correct

it's obviously [this other kind of glassware]

Imagine a camera the size of a point & shoot with a large sensor

Voigtlander Turnit 3 35/50/100mm Viewfinder vision3 Diaphragm is intactThe Turnit 3 (model 339 50)is a clever viewfinder that switches between 35mm, 50mm, and 100mm focal lengths with a quick rotation (and or a little door flip.) The 50mm field of view is accomplished with a mask over the 35mm, but the 100mm is thankfully not: the whole optical system spins around to change magnification, and that's why they call it a Turnit. In excellent condition, with light finish wear.
