B series Prakticas have bright viewfinders in contrast to the L series. I would guess there is oil on the aperture blades. Working the lever on the back of the lens back and forth might make it usable for a while.I just got a Praktica BMS electronic with a 135F2.8 lens. I am a lont time Nikon user but I read some interesting reviews about praktica and pentagon and I decided to give it a try.
The shutter and advancing seems to work fine (I haven't bought the batteries yet) but the viewfinder is very dark, to the point that I am able to focus only in full light. As I only have that one lens I wonder whether it could be a lens issue or a viewfinder issue, and if it's a known problem.
Update: I found the lens being stuck to the smallest aperture, I will try to see if I am able to release the aperture mechanism, but any suggestion will be more than welcome
