Sigma 70-200mm f2.8 EX APO IF HSM

Review Date: Feb 17, 2005 Recommend? yes | Price paid: $600.00 | Rating: 10 

Pros: Excellent optical quality, particularly wide open. Focusing speed. Build quality.
I really can't find any without nitpicking, I guess I would like it to have metal filter threads instead of plastic.

I was leery about purchasing this lens because for an additional $200 I could have had the Nikon 80-200mm 2.8. However after taking some pictures with this lens and comparing them to pictures from the Nikon I can actually say that the Sigma is sharper. I must have an exceptional sample because I shot a test series of shots from f2.8 to f11 and only noticed a few lines per inch drop in sharpness, basically not perceptible except in the largest enlargements. Contrast on the other hand is noticeably worse wide open, but I can live with that, as it is easily fixable in Photoshop. I am very pleased with this lens optically and am glad that I did not purchase the Nikon. I am not afraid to use this lens at f2.8, something I canít say of other 2.8 zooms I have used.
