It's a black G2 and lens, so hopefully it's repairable. Like I said it works great without the lens mounted. I read a thread about a similar problem here, so I thought maybe someone can help shed some light. however once I turn it off, it once again becomes unresponsive when turned back on. Sometimes I can get it to work by fiddling with the dials/lens, or removing the batteries for an extended period. The shutter button is unresponsive, and the viewfinder display doesn't turn on. It turns on, and the top left LCD display comes on, however that is it in terms of functionality.

HOWEVER, when I mount my lens, it becomes unresponsive.

The camera acts normal without the lens on, it autofocuses, the viewfinder display lights up and displays properly.

I have a problem with my Contax G2 and 35-70mm lens (my only lens).
