Product description

The revolution in the zoom

Because of its wide focal range, this 18-200mm is perfect as a standard lens for virtually any shooting situation. Especially in travel, ultra-compact and lightweight design allows you to enjoy photography. From wide angle to telephoto, this goal can master many photographic situations. The objective 18-200mm Di II is part of the tradition of the legendary Tamron megazooms range and provides a zoom equivalent to 11.1 X 28-300mm full format.

Aspherical lens elements

The aspherical objective virtually eliminate the problem of sagittal comma aberration and other lens types - even when used with the wider aperture. They are particularly useful in correcting the distortion in wide-angle lenses. Also, the use of aspheric objectives contributes to a lighter and more compact lens design.

Di II

Di II lenses are designed exclusively for digital SLR cameras with a sensor of 16 x 24 mm maximum (APS-C). The image circle of these objectives is therefore smaller, so it can not be used with full frame cameras, since vignetting will occur. This smaller image circle improves technical balance between the lens and the digital camera.
