the two 100/2.8 macros in that list are exceptional lenses. neither rotate
the front when focusing. the FA 100/2.8 macro is very heavy, while the D-FA
100/2.8 is much lighter.

Subject: question about primes: 100/2.8 and 135/2.8 FA (D)
Pentax SMC (AF):
FA 100/2.8
D FA 100/2.8
FA 135/2.8
F 135/2.8
Any comments on comparative optical (and otherwise) quality of them?
Any difference in AF speed and accuracy?
Do D-FA and FA 100 have the front element rotating?
