Originally posted by paperbag846 Apparently old lenses with set aperture rings would always have their lever fully pulled during shooting. With A lenses, the lever is pulled according to the aperture setting in the camera.
Therefore, pre-A cameras always fully pull the lever, bring the lens to it's minimum aperture.
That sounds right. Thank you.
I just tried fitting DA lenses to my old ME and what happens is I get an open aperture preview through the viewfinder but the camera meter shows a shutter speed that corresponds with the lens' minimum aperture.
So, it would appear that a DA lens acts just like an A-lens with the aperture ring set to the 'A' position (or a M-lens set to minimum aperture).
It's interesting that the old camera 'knows' what the DA lens' minimum aperture is.
