Originally posted by stevebrot Perhaps I misread your original post. I understood you as saying that your camera delays releasing the shutter for several seconds after the button is pushed (sort of like a self-timer). This type is issue would have nothing to do with the aperture coupling or metering. Unless, of course, you were really saying that with an adapted M42 lens mounted, the camera always does an unrealistically long exposure regardless of the metered value.
The delay after I press shutter release button only happens when I have an M42 adapter and M42 lens installed. When I have a K-mount lens installed, obviously without the adapter, everything works correctly (no delay after I press shutter button).
It is consistent in this regard. I have tested countless times with different k-mount lens and M42 lens.
The meter works normally with both k-mount, and M42 lenses.
I just had a roll of film developed. The photos that were taken with M42 lenses came out fine, which means beside the delayed shutter release, the camera works fine with M42 lenses installed?
Quote: So, the question is...What exposure setting does the meter indicate and does the camera actually expose to that setting?
The meter works fine with both. The exposures were fine, even with the delay.
I have tried both Auto, Manual, and 125X modes on the MES. It doesn't matter what shutter speed I set the camera to in manual mode. As long as an M42 lens adapter is installed, I get a delay after I press shutter release button, before I hear the mirror and shutter firing.
The camera is not taking long exposures, but rather the shutter delays firing after I press the button, only when it has M42 adapter installed. The delay does not occur when k-mount lenses are installed.
Quote: And...I may have missed it, but what does your camera do when no lens or adapter is mounted?
the shutter works fine. no delay.
