Show me exactly where I stated 'M42 adaptors do auto-aperture'. I didn't. As far as I'm concerned, the metering stop down button IS the auto aperture feature. They're directly (and physically) connected on M42 SLR's that feature that capability. That's exactly what I was referring to when I commented on the metering stop-down button, since it's all the same basic mechanism.
You don't need a metering stop-down button if the body doesn't do auto-aperture and you do if the body does do auto-aperture. There's no other reason for the stop-down button to exist. -Adam J. C.
