Originally posted by Rondec If you could find a F50mm f1.7, that would probably be the cheapest auto focus option. The DA 50mm f1.8 is pretty reasonable, but certainly will be more than the 100 dollar price tag, even used.
The DA 50 1.8 sells now used for about 130-140, and the F50 1.7 for 180+. That's for nice, clean copies.
If you find the latter under 100 dollars, please let me know where...

I have the Auto Sears 50 1.7 which is really a Rikenon XR 50 1.7 rebadged. It's alright wide open, sharp at 2.8 and pin-sharp at f4. The f2 is supposed to be even sharper, but I see nothing wrong with my 1.7.
I also have the XR 50 1.4. Super-dreamy at 1.4, ok at f2, and from f4 on it's a match for the 50 1.7 and the SMC Pentax-M 50 1.7.
None of these lenses cost me over 40 dollars...
