Canon EF-S 18-135mm f/3.5-5.6 IS - Review / Lab Test Report
29 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. Large aperture settings should be generally avoided at 18mm and beyond the middle range - the borders/corners are plain soft here. However, to be fair the lens is actually quite usable at f/8 (18mm) and f/11 (70mm+).
Summary: The Canon 18-135 mm is provided with an effective stabilization, and due to the wide zoom range practical in use. The speed is limited and in terms of resolution, vignetting and distortion, this lens performs only very moderately. The Canon 15-85 mm and Sigma 17-70 mm offer more but at a higher price. The low price of the Canon 18-135 mm ensures a reasonable price/quality ratio.
