I just got this camera this morning and the mirror was up the batteries corroded.
After some fiddling I got the mirror down but its not firing anything like normal.
You can wind on for forever and a day its not locking in although the rear shutter comes up
I think its behaviour changes with the bottom panel off or on
With it off if I wind the shutter on hold the winder out run the self timer wait for a click and then release the winder the rear shutter comes down if I havent been holding it nothing happens pressing the shutter button has no effect.
with the bottom on if i wind on the mirror comes up and the shutter releases when i let go of the winder.
I think when winding on a little piece is supposed to drop into place on the take up spool and get pulled out when the shutter release is pressed.
On the plus side it came with 2 pentax lenses one of which wasn't mentioned in the auction that turns out to be a 50mm m f1.7
as well as a 80-200mm f4. It did have it's eyepiece cover which none of my other camera's have and 2 flash guns a pentax af200s and a franka 214M but the flashes also had very corroded duracells inside so may never work at least 1 battery spring terminal has corroded off.
And a bonus halina automatic super8 movie camera (in a fairly sad state. Which i'm unlikely to ever use, It's £48 to develop a film!
Any suggestions as to a possible fix to the ME shutter or should I just be happy with the lenses.
