Harvey one of the guys on UHH told me that it was like using a 1.4X converter so u will loose some light. So a 50mm 1.4 would be like a 1.7. I do have one adapter w/o glass that work ok buy for close ups only. I am going to buy the new ones with glass & I will try to let you know how they work when I get it. Do the same for me will you.

As went thru the 2 camera cases from my friend this is the total of lens as well as a Pro Pentax Spot meter:
24mm 1:1.8 sc F1.8 - F16
50mm 1:1.8 sc F1.8 - F16
35 - 70mm 1:3.5 F3.5 - F16
70 - 150mm 1:3.8 F3.8 - F22
500mm 1.8
I feel this cash of lens deserves a second chance even if it is on a amateur/hobby basis.
