Thanks to its high focal range, this 18-200mm lens is a flexible zoom suitable for all shooting situations. Especially when traveling, its exceptional compactness and lightness prove to be particularl espandi...y satisfying. From wide angle to telephoto, most photographic situations can be successfully tackled with this lens. The 18-200mm Di II lens is in the best tradition of Tamron's legendary megazoom range, with an 11.1x zoom factor and a focal length equivalent to that of a 28-300mm lens for full frame cameras. The 18-200mm Di II uses the innovative XR (Extra Refractive) glass with a high refractive index to optimize optical performance over the entire focal range. Its optical design minimizes aberrations while allowing for a more compact construction. In addition, three hybrid aspherical elements were used to minimize spherical aberration, while two LD (Low Dispersion) glass elements were used to compensate for chromatic aberration. The result is a versatile zoom with outstanding optical quality. It achieves a magnification ratio of 1: 3.7, making it suitable even for macro shooting, with a minimum focusing distance of only 45cm. Everything to try this zoom with performance in relation to its category and also with a fantastic price / performance ratio.
