The first comparison test results I am sharing are from the absolute top left corner of the frame out of a As a generalization, CA is worst at 17mm and slowly improves through the balance of the focal length range. The Sigma 17-50 is slightly more expensive than the Tamron 17-50 VC, but the better-optically-performing Tamron 17-50 non-VC is considerably less expensive. Expect a relatively small amount of focus breathing from this lens - the subject/framing changes size a small amount when focusing.

As I mentioned in the beginning of this review, the Sigma 17-50mm f/2.8 EX DC OS HSM Lens has very good build quality. The Sigma 17-50mm f/2.8 EX DC OS HSM Lens is available in Canon (reviewed), Nikon, Pentax, Sony/Minolta and Sigma mounts. There are, however, many 17 to 50mm (or 55mm) f/2.8 lenses available from other manufacturers - I'll reference some of these later in this review.Use our percentage calculator to work out increases, decreases or percentage differences.

The Sigma 17-50 OS' fixed f/2.8 max aperture across the entire focal length range provides 4x as much light in the wind, on unstable footing, on a boat ... and in other situations where holding a camera steady is difficult and a tripod is not being used.

The longer focal length lenses frequently sacrifice image quality to obtain their range and most do not offer the fixed f/2.8 max aperture across the entire range.The relatively small lens hood is large enough to help keep fingers and other objects from touching the front element.

The Sigma 17-50 focuses smoothly, but with a relatively short 42° rotation and low rotation resistance, precise focusing is touchy.
