Conclusion: Overall, for the price of the lens, it is an adequate performer although the over reliance on autofocus and the all-plastic construction do raise a few concerns. At the short end, and focussed on infinity, there is virtually nowhere to grip the extending part of the barrel for manual focussing.
Pros: Light weight and simple construction, Good control of aberrations and distortion
Cons: Poor build quality, No dedicated manual focus ring, Plastic construction throughout, including mount., No lens hood supplied.
Excerpt: The Canon EF 55-200mm f/4.5-5.6 II USM Lens is very light and compact , focuses fast , has a good focal length range and is inexpensive . There is a Canon Lens Chart floating around that lists the 55-200 II as weighing 3.4 lbs.
Excerpt: Originally posted 2006-02-07 on Optyczne.pl The kit lenses that come with most DSLR cameras have focal length ranges starting from 17-18 mm and finishing at 55-70 mm. Most photo amateurs come to the conclusion that it is worth upgrading and getting a zoom lens.
Cons: the lens is not completely sharp for f/8 diaphragms, poor aperture, visible chromatic aberration at 55 and 200 mm focal length, for a USM motor-equipped lens, it missed too many times
Summary: Oczywiście za tą cenę nie należy oczekiwać cudów. Duże pole widzenia osiągnięto kosztem dużej dystorsji i komy. Sposób umocowania i ułożenia pryzmatów powoduje ogromne odblaski. Winietowanie przejawia się przez bardzo jajowate źrenice wyjściowe.
