With my adapter the lens pin is not pushed in, nor is it when placed on the body.
There are flanged and un-flanged adapters, of course. With the Taks, you usually don\'t need a flange because they have the \"Man.\" switch which forces the blades closed.
The OP\'s lens is a \"preset\" lens, which came long before the days of auto aperture. Hence, no pin and no switch.
One aperture ring is used to preset the desired shooting aperture and the secondary ring is used to stop the lens down just before shooting. When this lens was made, stop-down metering was all the rage.

I would think it is a manual version only. On canon, using M42 adapter, the pin is going to be \"IN\" all the time.
