Pentax FA100mm f2.8 macro
The FA100/2.8 macro is available at
I have this lens and the D-FA version. This one is better as a regular 100mm lens, and at least as good at macro distances (I think it is actually a bit sharper, with better bokeh, but this is an impression based on examining the many frames I've shot with both - I haven't rigorously tested it). The seller is unimpeachable - I am among the 100% of their buyers who think so - and I've never seen a price as low as the current offering.
Disclaimer - I have no connection to the seller, other than as a (several times) satisfied buyer.
