Aperture pin not being worked? If it's an Exakta/Exa-mount Flektogon like my 20 mm, with a shutter button mounted on the lens, you have to push the button to get the aperture to close down to whatever you've set it to. Other lens mounts often have a pin of some sort that has to be pushed.

I'm not familiar with that camera, but there is a pin or some kind of mechanism on the lens that stops down the aperture when you press the shutter on the camera - nearly every SLR has such an automatic diaphragm including yours (http://www.praktica-users.com/cams/six/pentaconsixmanual.html). When you set the lens to a small aperture and push that pin or mechanism on the lens, what happens?
