Dunno if it helps but: * range of the DA* is quite bigger * DA* is full frame as well ;) * Sigma is HSM-only (but true version, not micromotor like SDM). * I beleive the DA* is less heavy.
Either lenses are, it seems, excellent if I beleive what I read about those. AFAIK the converter (1.4 or 2X from sigma are not available in HSM version for Pentax). If that's the case, using the converter would set you back to manual focus ... -- Thibault Massart aka Thibouille ---------------------- Photo: K10D,Z1,SuperA,KX,MX, P30t and KR-10x ;) ...
