[langtitle=pl]Pentax 67 TTL Prism Problem[/langtitle]

I Have problem wyth my new P67. Well I can't turn the TTL off. When I put my lenses on the TTL is working great (meatering). But puting the lever to OFF on the prism isn't doing anything. Is there a way of repayring it or should I send back the prism to the seller ??

The camera is in great shape but after fiew hours of working wyth the camera the battery is dead maby I'm dooing something wrong ?? I read that after 10s the prism should turn off but using my time knob I can still see the TTL working...

Later P67 TTL prisms do have automatic off with a lightly spring-loaded switch that centers itself after a momentary contact to one side for ON and the other way to OFF.

But early TTL prisms have a two-position switch that clicks one way to ON and stays there, and the other way to OFF and stays there. If you have this sort, you need to manually turn it off when not in use.

I have the later TTL Prism wyth the center position of switch but it stays always on... If I take the lens of the camera than using the On switch turns the TTL of and using Off switch turns the TTL ON ... backwords. But when the Lenses are on camera can't turn the TTL OFF

After not using for fiew second's the camera should the TIP of the indicator go down to zero position at the bottom or should be in working using time switching ??
