Hi all, I'm having a problem with my newly bought 159. The mirror gets stuck in upwards position when shot with a lens on. It shoots without problems without a lens on. It's not a battery problem. Once I remove the lens the mirror returns. The foam looks good and there doesn't seem to be any mirror slip. I'm thinking there is some problem with the coupling between the body and the lens. Has anyone heard of a similar problem, or have any clue as to a fix?
EDIT: actually there might be some mirror slippage. Should the mirror sit flush with the holder edge?
Thanks!

Hello cantaloupe and welcome to the Forum! You have correctly diagnosed the issue - a classic Contax mirror slip. The mirror is held in place by double-sided tape and under certain conditions, the glue can melt resulting in the downward slide of the mirror such that it's no longer flush with its mount. It takes very little displacement to foul a lens in which the rear element is flush or slightly beyond the plane of the mount. There are quite a few online suggestions as to how to resolve the issue - a classic method is to use a hairdryer to melt the glue again and then push the mirror back into its frame, after which you pace the camera on its back in such a way that the mirror is vertical and left overnight. The mirror should have re-seated itself nicely and the camera can be used safely again BUT the glue may have 'memory' and over time will travel forward again. I'm aware of people that have used heat to re-melt the glue and then applied a dab of superglue in addition to pushing the mirror back into its frame. As the height of the mirror in its frame is a critical part of the focusing system, it is inadvisable to remove the tape unless you can be confident of replacing like-with-like. If you are uncomfortable blasting the mirror-box with heat, any competent camera repairer should be able to help - at a price...
