Review on Enhanced Canon EF 70-200mm f/4L USM Telephoto Zoom Lens for Canon SLR Cameras - Lens Only with Improved SEO by Jhalak Mehra ᠌

Very convenient tele-zoom. I use with 7d. Shows himself great. Very sharp. Unlike 17-40L, it does not require any sharpening in post-processing. Very fast and quiet USM. The lens hood still protects the lens from rain and snow. Despite the low aperture, you can shoot even in the evening - there would be a desire and straight arms. Pros below: Lightweight, durable, comfortable, beautifully paints and washes the background, but sharp, predictable, the focus switch (3-infinity) is very helpful when shooting sports. Affordable accessories. Has some cons Sometimes (very rarely) the focus misses. And considering that here it is quite long, refocusing takes some time.
