I think the lens is more than worthy for its money. The rest is either "unlucky", or chatter . There were canons with a fleet of optics . I refused because the lenses simply did not become (f. F., B. F.) It turned out soap. I took D 90 from 18-105 - I enjoy life . Then I bought more: 70-300; 50(1.4), 24-70(2.8). And all from NIKON. I'm glad, and I wish you all the same. Got pros: Focal lengths, focusing speed and volume, Stabilizer, X. A., sharpness, equipment . With its cons. Desire for more for the same money: bayonet, aperture ratio, etc. .
