Originally posted by CFWhitman The lenses are all the same. I don't really have a good explanation for the price variations. I just look for what I can get for the least money. I have never seen one of the new generation of Samyang lenses (the lenses released starting with the 85mm f/1.4) for Pentax which did not have an 'A' setting, so them all having it should be a safe assumption.
That is what I thought. B&H has them priced that way whereas Adorama has them priced a different way with the Samyang version being the lowest, if I remember correctly. These are all APS-C designed right? So, I will get vignetting if I slap it on one of film bodies?
