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 Md Aadam Ali ᠌

Bought together with 7D (separately), with my first DSLR. Accordingly, the lens is the first and there is nothing to compare with. I have been using it for a month, happy as an elephant! It is only unclear whether the focal millimeters written on the lens should be multiplied by 1.6 or not, if, as it is written, that it is only for cropped cameras? And about the leaving tube under its own weight. There was advice from a professional photographer. When buying a lens, if you take it vertically in your hand and turn it over sharply, the tube should not pop out. If it jumped out, then the lens is after repair. Like this. I don't drive myself)
