Sigma 17-50mm f/2.8 EX DC OS HSM Lens

Completing my migration from Canon lenses to Sigma EX DC lenses is the Sigma 17-50mm f/2.8mm f/2.8 EX DC OS HSM lens. So, my lens lineup now consists of the two Sigma zooms which give me focal lengths from 17mm to 150mm and the 10mm fisheye, all with a fixed maximum aperture of f/2.8 together with the 30mm f/1.4 lens.

Because of the change to third party lenses I will have to learn how to use Lightroom as the lens correction tools in Canon's DPP software only works with Canon lenses. I have dabbled a bit and have successfully fixed some purple fringing with Lightroom so it'll just be an adjustment period while I learn all the controls.

Here are two shots illustrating the focal length range of the 17-50mm zoom which has the field of view of a 27-80mm lens on a full frame camera These were made from Lock 4 looking toward Lock 5 on the Champlain Canal in Waterford, NY.
