I am trying to understand how to use the aperture ring on FA lenses (the 43/1.9). I set the aperture ring to anything other than "A", and the camera mode to AV. The aperture size in the viewfinder reads "F--", which is understandable. Now, I set the aperture on the lens by rotating the ring. I was expecting the shutter speed to change automatically. Unfortunately this did not happen. Also, no matter what the aperture ring setting, the photo is taken with the aperture fully open. Even the DOF preview doesnt seem to close down the aperture (though it does make a nice click sound).
If I set the camera to M mode, things work as expected - I set the aperture on the ring, press the green button, and the camera closes down the aperture and figures the required shutter speed. The captured photo has the right aperture setting and shutter speed.
Am I missing something here? Is it not possible to use the AV mode with the aperture ring?
Update: Okay, I really need to learn how to use search before posting a question here.
This thread basically answers the question I asked above.
