Excerpt: I use his lens mainly for landscape and candid portrait work. I do most of my work on the coast of the north shore of Long Island. I need a lens with good mid range and the 18-200 fits the bill, It produces sharp images at all focal lenghts.
Excerpt: I have had this lens for several years and use it almost exclusively, forgoing most of my fixed length lenses except for "super telephoto". The lens is fast, versatile and provides clear sharp images, while zooming quickly and steadily. I seldom use the autofocus, so I can't really comment on that, but otherwise I would recommend this lens for almost any use short of full professional.
