Tamron AF 18-250mm F/3.5-6.3 Di II LD Pentax Mount

Di II: Lenses are designed for exclusive use on digital cameras with smaller-size imagers and inherit all of the benefits of our Di products. These lenses are not designed for conventional cameras and digital cameras with image sensors larger than 24mm x 16mm.

Tamron's new high-power zoom lens is a photographer's dream come true — it is the result of Tamron's continuing mission to develop the world's most unique "one-lens-does-it-all" zooms to satisfy our customers' desire. While conventional 35mm film cameras required two lenses to cover 28-388mm, Tamron's new zoom is 13.9X, the world's most powerful zoom delivering enormous photographic freedom in a single compact lens. The life of a digital photographer has never been better.
