Tamron 18-250mm Zoom Lens

Tamron has unveiled its new AF18-250mm F/3.5-6.3 Di-II LD Aspherical (IF) Macro (Model A18), a lightweight, compact and ultra high power zoom lens designed exclusively for digital SLR cameras with APS-C sized imager sensors.

The new telephoto lens offers the longest focal length of 250mm among those that start with an 18mm wideangle.

Tamron said Di-II lenses are not designed for use with 35mm film cameras nor digital SLR cameras with image sensors larger than 24 x 16mm. The ratio Tamron uses to convert 35mm focal length equivalents is 1.55X.
