Review on Canon EF-S 15-85mm f/3.5-5.6 IS USM UD Lens: High-Quality Standard Zoom for Canon DSLR Cameras by EN Tien ᠌

This miracle of technology from Canon washed the lower left corner, but the effect did not always appear, but only at focal lengths from 15 to 35mm, and at any aperture value. But the most interesting thing is that not on all frames. In general, some kind of floating defect. I contacted the service, they said "even though everything is within the tolerance of Canon, but we have adjusted it a little." As a result, I only lost time, because they did not adjust anything and everything remained within the "tolerances". Well, in general, I don’t like such “tolerances” at all. By the way, I’ll say that I didn’t have a single Canon lens that was perfect (I had several of them, including fixes and even one L-ka). Someone may say that I don’t know how to take pictures, that I don’t need to look for jambs, but to make masterpieces. But I want masterpieces to be made with the technique you love. But this is poetry. After understanding the attitude of this company to their products, I sold all the lenses and the body and switched to another system.
