Can anyone advise me between these lens -Canon EF-S 10-22mm f/3.5-4.5 USM Lens vs Sigma 10-20mm f/3.5 EX DC HSM???


I had tried my hands on theSigma 10-20mm f/3.5 EX DC HSM. It was absolute gorgeous. The fixapertureis a great feature too. However, I notice because it is not a Canon, I cannot use certain feature of the DPP to correct the photos taken with this lens (such as CA correction & lensdistortion). This is a minor setback but I might be wrong.





Please advice.
