VladM's comment about the SMC-A 70-210 is IMO correct, it is probably the best value Pentax zoom on the Second Hand market. In the UK they often sell for less than £75, which for a fixed F4 maximum aperture through the whole zoom range coupled with excellent quality makes it a great buy. You could take the view that it is the
"poor mans 60-250" - same aperture, slightly reduced range, solid build, and there's a theory that it has the FREE (Fixed Rear Element Extension) that was usually reserved for high quality primes - so the only thing missing is AutoFocus.
Hi SyncGuy - I'm afraid that my "letting go" of the A 28mm f2 has already happened
- I only post my For Sale lenses on the UK forum (as I only ship within the UK) and that one went a few months ago. I have just updated my profile with a more accurate list of lenses, and most of the A's will go in the near future.
