It has been awhile since my last post in this group. But the other day a new item arrived via mail, found it here in Norway. Not to many of these around I think. I have now 2, do I need 2?

A Kowa Set I owned. It is a hard camera to find in working condition or repair. As it is one of the few leaf shutter SLRs with interchangeable lenses.

The Zeis Icon and Kodak Retina SLR are another two with leaf shutters. This arrangement is so complex, that it is no wonder it was dropped. The shutter has to be open to look through the lens, so a blocking plate has to shield the film. Then, on shutter release, the lens shutter has to close before the blocking plate is lifted, then finally the shutter opens for the required time before shutting and allowing the blocking plate to swing down. Once that happens, the shutter can open again so the cycle can repeat. At least that is how I understand it.

I need to check. The rechargeable batteries are long gone, and cannot be bought new, but the last find have a holder for AA type batteries included. So I will try for sure.

The Zeiss SLR made this complex system work well, primarily because the camera itself was a very convenient compact size, and the f2.8 Tessar was an excellent lens for general photography. Consequently the various manifestations of the Zeiss remained in production for a long time. The other SLR that successfully used leaf shutters was, obviously, Hasselblad. The leaf shutters were valued by fashion photographers for using big studio strobes, and editors liked having the big 21/4 square chromes spread out on a lightbox. There was no instant return mirror, which somewhat simplified the film-shield shutter mechanism. Hasselblad did experiment with a focal plane shutter, but that model was not successful.

Which is, of course, the one that the Soviets decided to copy.

Could be because the mechanical design was much simpler, especially because there's no instant-return mirror.
