Review on Sigma 17-50mm f/2.8 EX DC OS HSM FLD Lens: Large Aperture Standard Zoom for Canon DSLR - International Version (No Warranty) by Ada Szwed ᠌

Aperture + stub = power! The lens allows you to shoot without a flash in conditions in which you would not have tried before. Previously, due to lack of money, I used a used Sigma AF 28-300mm f/3.5-6.3 DG MACRO. When I got better with finances, I thought about buying a better lens and changing my Canon 1000D to 600D. When I purchased this lens, I realized that the old carcass would still live. Pleased with portraits taken at 50mm and a viewing angle of 17mm.
