Fotodiox had a sale on their Bronica lens adapter. So I picked one up and found a PG lens on the bay,
The adapter is well made and the inner surfaces aren't as reflective as previous adapters. It fits both camera and lens well. I did add flocking inside to make it even less reflective.
The Bronica PG lenses were made for the last Bronica SLR - the 6x7 GS-1. The lenses have leaf shutters that do not function with the Pentax 645. The 150 lens is the smallest of all PG lenses. Many Bronica users praise the bokeh.
Using the Pentax 645 with the Bronica isn't difficult. It does require stop down metering. There is one small hitch. The adapter has no way to stop the lens down. It is always wide open. The lens has a button for depth of field preview. It doesn't lock. I use a wire zip tie to keep the button depressed.
I think the lens performs nicely. It has nice bokeh and F4 gives a little more depth of field than the Pentax 165 F 2.8.
Here are a few pictures processed in my normal fashion.
Thanks for looking,

Tree full of blooms was shot at F4. Tree trunk at F8. Both on tripod.

Reason: Fixed error. Tamron owned Bronica, not Tokina. Lenses were designed and built by Bronica.
