Hi all,

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.
Thank you for all of your advised.
