My latest toy, a fast prime with very good image isolation capability for 3D rendering. Purchased the lens as a birthday gift to myself. It’s currently my most expensive and the  fastest AF lens in my collection. I had to purchase it locally so that I can have it fixed for any front or back focus problems which are very common to any AF lens – specifically coming from a third party supplier such as  Sigma.  Here’s the first picture that came out from my Kx when the lens was fixed after being adjusted for back-focus problem:


As can be seen from the pictures, the Sigma has more of a blue rendition compared to Pentax lenses. More pictures below:
