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

In general, in my opinion, Canon created a series with an EF mount and aperture ratio of 4 and higher for FF as budget optics. In terms of picture quality, it is no different from the EF-S analogues in nature, in bright light. This is amateur optics, and you need to treat it accordingly. More advanced lenses come in at f/2.8 and below (not counting those that aren't L). After all, this 70-200 can really be replaced by 18-135 or 55-250 with a gain in zoom. In aperture they are all dark. I used it on my camera, I took it from a friend. There is no stub - a huge minus in the room, f is rather weak. I would advise everyone to save up at least for 70-200 f / 2,8 usm, otherwise switch from a whale 18-135 - spend extra money for nothing. I do not recommend third-party analogs at all. After all, as they say, only the new Canon can be better than Canon. :) Choose, friends.
