This morning, I got up early for a sunrise shoot at Montreal's Old Port. Gorgeous sky.
One of my lenses is a Super-Takumar 85mm/1.9. I have had it for six months and used it many times without a problem. This morning, when I put it on my DL2, the camera started behaving weirdly.
Normally, screw-mount lenses default to Av mode. They can also be used in M mode. But when I turned the camera on today, the camera defaulted to Tv mode.
Wha--? The scroll wheel was controlling shutter speed, when the camera should have been in auto-exposure mode. It should not even be possible to put the camera in Tv mode with a screw-mount lens attached. The lens itself was stuck wide open.
I removed the lens and checked that there was nothing mechanically wrong, and there was not. I switched the lens back and forth between Auto and Manual aperture control. I turned the camera on and off. My DA lenses worked fine, but the Super-Tak did not.
I have since reset the camera, and everything is working fine again. But I am in the dark as to what could have caused this odd behaviour, and I don't know if it will happen again. Any ideas?
