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 Aneta Jagieliska ᠌

Consistently good picture quality. With appropriate camera settings and lighting, of course. Gorgeous photos outside during the day. did not disappoint for six months. With its pros. Cutting Solid (I shoot weddings on a canon 600d, with such a lens no one looks at the camera model) Softly blurs the background by 2.8 Cons: I'm going to switch to full frame, it's a pity that the lens will not fit. When shooting against the sun, sometimes I caught round glare, but this may be from a protective filter, I'm not sure.
