I recently purchased a pentax lx film camera. It had a decent lens on it so I wasn't that concerned if the camera didn't work. And of course it didn't. There is no indication that the light meter is working.
The battery compartment has no corrosion and seems to be "all there". However it has a contact for the plus side of the battery along the side of the compartment and as far as I can tell does not have a negative contact. The bottom of the compartment where the negative part of the battery(s) contact is a rubber or flexible plastic membrane. The membrane is not conductive. This is a lot different than any other pentax film camera that I've seen.
In the photo above the + contact is at about 5 o'clock.
If a viewer has an LX and could let me know what the battery compartment looks like it would be appreciated. Better yet a photo of the open compartment would be a great help.
Thank you,
John.
