Sorry, did you mean you returned the Sigma or the Pentax?

I brought the Pentax 16-45mm yesterday,i compared it with the sigma
18-50mm EX f2.8 in the shop, i found the 16-45mm more sharper than
18-50mm EX f2.8 and the sigma show me slightly back focus at
f2.8,f3.5 and f4, the Pentax 16-45mm show me correct focus and more
sharp pic. ,so i brought it back.
