Review Date: Oct 30, 2006 Recommend? yes | Price paid: $700.00 | Rating: 8 

 
Pros: sharp at smaller apertures; excellent color reproduction; well built (heavy metal base; magnesium tripod collar); quiet/fast AF motor
Cons:
poor exterior paint quality; slight off-focusing at higher focal lengths and larger apertures when mounted on the Canon 10D body

I was somewhat diappointed with the off-focusing effect at focal lengths from 135-200mm and using apertures from F3.5-F2.8 (on a Canon 10D body). A review of several internet forums revealed that other users have experienced similar off-focusing effects when using the larger apertures, longer focal lengths. With a little experimenting (to avoid sending the lens to Sigma for inspection), I found the best results come with focusing manually and compensating for the slight off-focusing. It takes some practice, but the practice pays off. After a year of use, I can confidently say that this lens performes very well, producing very detailed and sharp images at the smaller apertures. Colors are reproduced accurately, and the bokeh resulting from this lens can instill unique qualities to portraits; highly recommended for the price, image quality, and build quality.
