In reply to Only a hill:
Nice thread, though it appears I'm a little tardy! The previous recommendation of the pentax forums is a good one, as it's an excellent rescource. I sport a Pentax SV, (similar to the Spotmatic but without a meter; though I have a Gossen Profisix for that), with the GDR Pentacon 30mm f3.5, (great perspective in most situations), and a Super Takumar 55mm f1.8. I've been looking at the following wide angles:
Tamron 17mm f3.5
Tamron 24mm f2.8
MIR 20mm f3.5 (though is allegedly heavy).
Super/SMC Takumar 17mm or 24mm (if money was no object!).
