Yeah, but D-FA implies it has an aperture ring. D* would be a new line perhaps? Or maybe DF/DF* (DF 35/2.4, DF* 200/2.8)
You should send a note to the DFA100mm WR since it's missing one

Hrm...how peculiar. In that case, since D-FA bears no real implication, that'd be much simpler.

Isn't that Pentax language where D(A) stands for digital (APS-C) and F for film (35 mm Full Frame)? Hence DFA lenses are suitable for FF.

D FA would make sense for FF digital. Which means Pentax will probably call them DQ or something.

I was always told an FA implied it had an aperture ring, for use on older K-Mount bodies. Maybe the 100mm Macro is a one off?(I mean, it's a weather sealed prime that isn't DA*...)

I can confirm this based on film shots, though you can see slight softness in the corners wide-open.
Could it be some field curvature?

You know, they could have just made a nice 1.4 or 1.7 TC that would work on the DA*300 and that would have given the average person a nice 5.6 or so 500 mm lens on an APSC camera for less than 2 grand. But no, they make something that the average person isn't going to buy just to say they made it. Silly. It would only take 14 $500.00 TC's to equal the price of this lens, and I bet they would have sold a TON more TC's than they every will this beast. But, on the other hand, now no one can say Pentax doesn't have long glass in their lens line up.

DA 1.4x TC is on the road map. http://www.pentaximaging.com/files/pdf/lens_roadmap.pdf

WR is less sealing the AW (all weather) that the DA* lenses have.

About the FA i believe so but this is DFA so different series?

But no way am I gonna make that one. I am young enough that it is at least theoretically possible for me to live long enough to see the TC though.

I guess I spoke to soon. Some of the film shots looked perfectly fine, but the vignetting sky test did show very dark corners. Stay tuned to the homepage for a full investigation.
