Many Years ago I owned a Penti II, but didn´t use it. So I sold it. Now I found a Penti I one on a flea market and got a brick of Orwo NP 20 film in SL cassettes. On the first walk with the Penti the shutter got stuck and something rattled inside the body. Ever tried to open a Penti for repair? Forget it!
The lens of the damaged Penti is still in use on my Lumix G1
