Tamron develops high-power zoom lens from 16mm to 300mm for APS-C SLRs

Tamron announced the development of an advanced new all-in-one zoom lens (Model B016) exclusively for digital SLR cameras with APS-C size image sensors that provide an amazing 18.8X zoom ratio. With a minimum focal length of 16mm (35mm film equivalent: 24.8mm) at the wide-angle end of the zoom range, and a maximum focal length of 300mm (35mm film equivalent: 465mm), this remarkable new lens provides a zoom ratio of approximately 18.8X. The new lens provides a minimum focus distance of 0.39 m over the entire zoom range, with a maximum magnification ratio of 1:2.9. This makes it possible to get right up close to the subject of the photo to enjoy easy, stress-free macro photography.

This includes three Molded-Glass Aspherical elements, one Hybrid Aspherical element, two LD (Low Dispersion) elements, one XR (Extra Refractive Index) glass element, and one element of UXR (Ultra-Extra Refractive Index) glass, which has greater refractive index than XR. The full use of specialized glass elements in the design contributes to thorough compensation of optical aberrations. The lens sample will be on display at the Tamron booth at the CP+ 2014, which will be held from February 13 to 16 in Yokohama, Japan.
