>>2719162>FA 28mm/2.8I have the M and A series of this lens, and they are nice. They were probably mu favorite walkaround lens back when I shot film.
There was a time recently when I was progressively updating my A and M glass to A series or newer, but it was watching the prices get jacked higher and higher by collectorfaggots on ebay that put a stop to that bullshit. Then I realised the newer zooms are better anyway.
The 28mm/2.8 i lurk on ebay has been presenting for ~300USD lately, which is fucking ridiculous

http://www.pentaxforums.com/lensreviews/SMC-Pentax-FA-28mm-F2.8-Lens.htmlA few months ago I decided to spend 400AUD on the sigma 17-50mm/2.8, and have been very plesantly surprised. Now I have no inclination to want to 28mm at all.
the 17-50/2.8 effectively replaces all 3 of my favorite film-era lenses:
Sigma 16mm/2.8
M-series 28mm/2.8
M-series 50mm/1.2
So yeah, the F and FA 28/2.8 are nice.. but not worth what people typically demand for them now.
