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 Chasmod Ray ᠌

I wanted to buy a good lens at an adequate price to replace the whale lens, I read a lot of forums, and settled on this sigma. I bought the first copy without testing, came home, started taking pictures, revealed a strong front focus, handed it over to the store, bought a second copy, the image quality turned out to be worse than on a whale lens, and a strong front focus. Nobody does the alignment in Hong Kong, so I had to return it, I checked the tamron 17-50, which is also a strong front focus, passed it, took another copy of the sigma, it hits right on target at 50mm. This lens makes me happy so far. A little yellow, but if you set the bb correctly, then everything is fine. Sharpness compared to whale is simply flawless. This lens is worth the money, but the main thing is to check the quality in the store, do not be too lazy to test, if you are a beginner, do not trust the opinion of the seller, it is better to call a knowledgeable person with you to help test. For this money with such a focal length it is difficult (even impossible) to find an analogue of this lens
