He probably likes the quieter AF (probably speed too)

I had been debating back and forth between the Sigma and DA*, both are very good lenses, and I finally decided to pull the trigger on the DA*. For me personally, I'm not too concerned about SDM--I'm an owner of a DA* 16-50 and have had no problems so far... However, the biggest consideration to me was the slower AF on the DA*, but I still decided to go for it because of a number of reasons... Some of which are-- bokeh (yes, I am pulled in by it's fascinating nature), size (both body and filter), and SMC coating (I can tell the difference, Pentax just has it figured out).
AF may be sluggish on the DA* but it's dead on accurate, according to users (I'll confirm this when I receive my copy in a few days). However, the Sigma, though fast AF, is unpredictable. You may just turn out fortunate and get a stellar copy and not have any such issues. ;)
Anyway, I wish you well... And do let us know how this next copy turns out! :D My reasoning is to give a lens three tries and if the third isn't good, then defer.

Are you talking the Sigma 30mm f/1.4? If so, that is in PK mount... At least afaik.

if you just keep getting bad copies (like the one you have)(btw, don't settle for something that you're not happy with), then you could ditch Sigma and get the DA* 55mm...
Just a thought anyway.
