Excerpt: Bundled often as a kit with the Canon EOS 7D and 50D, this APS-C format zoom ($450, street) is for shooters who want more than a bare-bones 18–55mm kit lens without paying $575 (street) for the extra reach of Canon’s 18–200mm IS superzoom.
Summary: It's also a sensible move for Canon to introduce what's effectively its first intermediate EF-S kit lens. Previously it was a big jump in price from the basic EF-S 18-55mm IS to either the EF-S 17-85mm IS USM or its successor the EF-S 15-85mm IS USM.
Pros: Flexible 7.5x range zooms 2.5x closer than basic kit lens., Effective Stabilisation with 3 stops in our tests., Metal lens mount and non-rotating filter mount., Affordable step-up from basic kit lens.
Cons: Soft in extreme corners, especially at larger apertures., Noticeable vignetting and geometric distortion., Loud AF motor, and MF ring rotates during AF., Some creep between 20 and 85mm (actual).
Excerpt: Originally posted 2010-10-18 on Optyczne.pl Canon resisted the megazoom trend for quite a long time; its competitors’ strategy has been quite different though. Nikon has offered its customers the 18-105 mm VR, the 18-135 mm models and two version of a 18-200 mm device.
Cons: lack of ultrasonic autofocus motor (USM),, unsatisfactory image quality on the edge of the frame at the maximum relative aperture and longer focal lengths,, vignetting particularly bothersome at the both ends of the focal lengths range,, significant distortion at the widest angle,, work against b...
Canon EF-S 18-135mm f/3.5-5.6 IS - Review / Lab Test Report
19 October 2009
Conclusion: The Canon EF-S 18-135mm f/3.5-5.6 IS may be somewhat better than the EF-S 18-200mm f/3.5-5.6 IS but it's not exactly a good lens either. The resolution makes a rather wild roller coaster ride through the different quality levels.
