Camera Lenses

This ultra-telephoto lens has a fast maximum aperture, and also features a new super multi-layer coating, which optimizes the characteristics of digital SLR cameras. Two ELD glass elements in the front lens elements reduce chromatic aberration to a minimum and also ensure sharp, quality images of high contrast.

User Reviews about Sigma 500mm f 4.5 EX DG IF HSM APO Telephoto Lens for Pentax and Samsung SLR Cameras

I am surprised at the performance. I also own the Sigma 300mm f2.8. It is pretty good also. The 500 is excellent in a light weight 500 super telephoto. And not to cheap anymore. Kinda pricy. If i had it to do over again i would buy the canon or nikon version. They have many features that are better. But I already owned the Pentax K-7 and 1.4 and 2.0 T.C. 's. So as not being one to make a living shooting wildlife it is just exceptional for me. Don't listen to the guys that say Sigma is second best in IQ. It is almost there with them now...

Update:
After shooting with the lens and using a dedicated Sigma 1.4 T.C. I can say that in good light I cannot tell the difference between this and the Canon or Nikor counterparts. It really is that good. It is exactly where it should be with the MTF chart readings I think. This is one product i can recommend without any problems. It is extremly sharp. -- So far so good
