Bill, my Novoflex (expensive) Pentax to Leica adapter has a ring. So it can be used in at least two different ways:
1. The ring is at its close-most position. Then the lens would behave like regular K-mount lens (no A-position) - you click, the aperture closes right away, you focus, aim and take a shot. Camera measures with closed aperture. 2. You set the lens at certain aperture, including, but not limited to, the A position. Then you rotate the ring on the adapter thereby setting any effective aperture you like. The shooting is the same except that you control the aperture with the adapter ring. Since you see what you get on the EVF - it should be rather easy, at least in theory. The downside - the ring on the adapter has no markings, so you close aperture to _some_ value, without really knowing what it is. Generally I shoot by controlling the aperture on the lens, and not on the adapter. I suppose that technically my Novoflex should be no different than yours except the target mount.
