Have the opportunity to buy these lenses. Primary use will be ist-D but Z1 and others also (see signature). What do you think of these?
* Sigma 28-70mm 2.8EX Asph * SMC Pentax-F 28mm 2.8 * SMC Pentax-F 20mm 2.8 How are these doing on the D? I seem to remember that the 20mm wasn't all that... I do not currently own any 2.8 zoom. Of course 28-70mm on a D is not that interesting... 28mm makes a 35mm (more or less) and a 20mm makes a 30mm. My Only AF prime is FA 50mm 1.4. I also have the DA 18-55anf the F 70-210 but a couple primes would be cool ;) ---------------------- Thibouille ---------------------- *ist-D,Z1,SFXn,SuperA,KX,MX, P30t and KR-10x ...
