Or the identical Ansco version, the Super Speedex. A while ago I had a Super Isolette which was excellent. For some reason I sold it; I kicked myself for a couple of years over that stupid decision. Then a few years ago I found a Super Speedex with a locked up focus helical for a decent price. Got that sorted out myself. I'm not selling this version, even though I don't use it all the time.

The other folder with a coupled range finder I have used is the Zeiss Super Ikonta 532. It's an excellent camera, but a bit bulkier than the Super Speedex. It also has a fast f/2.8 lens. And they only shoot 11 frames on 120 film. Still highly recommended for the price. I'm tempted to sell mine since I haven't shot it in years, but for some reason I still hold onto it.
