I recently came across a Tamron CONVERTO lens, 128/2.8, with an SR/MD converter mounted.

It has ~12 aperture blades, and pre-set aperture rings.
Mine has a chunk of the filter thread broken off.

Someone else has one on eBay right now in better condition, for a lot of money, with pictures:

Note to anyone interested in one that the Converto 'T-mount' may not be the modern one. It may be a T2 37mmx0.75mm; see Tamron Converto 135mm | The Camera Collector
