Originally posted by Docrwm No, that is not what has happened in the past when the 50/1.8 was more reasonably priced as it is now. The 50/1.4 is both faster and fully Full Frame ready, plus it has an aperture ring. They are different lenses and the 50/1.4 price is significantly higher now new. All of which will likely continue to support a higher price for the FA50/1.4.
FA50/1.4 was used to be $200+ NEW a few years ago.
I saw there are couples of used copies selling here, asking around $250 can't go quickly. I also watched on my local used market, lots of FA50/1.4 asking $200~$250 have been there for weeks and weeks.
btw, my copy of FA50/1.4 has very poor performance at aperature 1.4~2.0. I am only confident of using over f/2.8 for good sharpness.
Full Frame? I think it's a joke for Pentax! ooops, now for Ricoh!
