I don't buy special edition lenses or camera bodies, that is my one rule. Because special editions are worth more in mint condition and if you know me at all, lenses I use (
especially if they are good) don't stay in mint condition or long.
Pentax K5IIs - Pentax SMC-K 50mm f/1.2 @ f/1.2
Originally posted by pinholecam Curious to know if there a difference optically from the A50/1.2?
Pentax would have to use lead free glass, as the limited edition LX and 50mm f/1.2 lenses were produced circa 2000. So there probably are a few
minor differences in the optical formula to compensate for the different refractive Indices of the individual lens elements. This had to be done so the production of the cameras was compliant with ROHS - a policy that swung into action in the same year.
