The 18-200mm f/3.5-6.3 XR Di-II is a high power zoom lens designed exclusively for digital SLR cameras using the more compact (APS-C) digital size image sensors. The focal length of this lens is equivalent to approx. 28-300mm in 35mm format.Designed as an "all-in-one" lens, it will meet almost all photographic opportunities without changing lenses. The 18-200mm zoom lens realizes an MFD (Minimum Focus Distance) of 1.5' (45 cm) over the entire zoom range by the employment of a new optical/mechanical design configuration. Since the maximum magnification ratio at f=200mm is 1:3.7, you can enjoy close-up photography easily and conveniently.
