I have seen the aperture ring-less Tamrons. Basically how it works is the
lens is permantently set to 'A'. Fine while using a camera like the PZ-1p
where you can adjust the aperture on the body, but the MZ-5n and ZX-M (my
camera) don't allow this, so you are stuck with the modes you can use while
the lens is set to 'A'. On a manual body like the K1000 you are simply
screwed.
I learned the other trick from the list. IIRC this is how Tanya was able
to use the Tamron 135mm with KA Adaptall on her ZX-50, the KA adaptor
electronically makes the minimum aperture setting into the A setting, but
on the aperture ring you still see 32.
