In my experience, it can be difficult to get the aperture correctly in grip, when mounting the adaptor to the lens first. It's often easier to mount the adaptall to the camera first to ensure that the aperture simulator gets it's grip correctly. (This is often described at the correct prosedure for converters - but in practical life, it's more convenient to have an adaptor on each Tamron lens, so changing lenses is the same procedure as for a normal, dedicated lenses). AFAIK the Adaptall-2 mount makes it possible to trasfer info through A-contacts (for shutter priority AE). Adaptall (1) is K-mount compatible - not KA.
If you have a Adaptall mount for screw mount bodies as well as a Spotmatic - what is your problem?
