I have a Contax 645. I have the battery grip for it so I power it with 4 rechargeable AA batteries.



The problem: sometimes without any explanation the yellow exposure scale in the viewfinder goes blank. The f/ numbers and shutter speed info disappear in the viewfinder and the whole camera goes blank. I try to press the shutter button but all I can hear is a clicking noise. I keep trying and all of the sudden the viewfinder is back and I can see the exposure, shutter speed, etc. I have tried to change the batteries and replace them with freshly charged ones but I don't think that the low battery is the problem. I have another Contax 645 and that works without problems with the batteries.



Did this ever happen to you? How can I fix it? I can't rely on the camera if it just decides not to show me exposure, shutter speed, etc info. It always comes back but some times it takes 4-5 minutes... What to do?



Thanks for helping!

Pardon me for suggesting you go elsewhere but historically i've not seen many contaxt users on photozone. However, I know quite a few current and former users can be found @

I agree. There are not too many users around, unfortunately. I have tried other forums as well but it is the same there as well. I just hope that there is somebody here in this forum who once used this camera and would be able to help me...

well, i'm no contax user, but your description sounds like some electrical failure, you describe it as if the camera goes dead, i.e. looses power. Given that the body most be old, a simple point where electric equipment fails is poor contact with the batteries, the contact points may be corroded. Clean them, use even sanding paper. I have a remote control that fails occasionally, until I rotate the batteries a couple of times (which rubs the contacts), and it works again.
