Tamron is trumpeting their new product, the AF28-300mm F/3.5-6.3 XR Di VC LD Aspherical (IF) MACRO zoom lens, designed for SLR cameras with full-size format (Model A20). The new lens is equipped with a Vibration Compensation (VC) mechanism to reduce blur due to camera shake.
Tamron says the AF28-300mm F/3.5-6.3 XR Di VC is the ultimate high power zoom lens that covers everything from wide-angle to telephoto and macro.
When used with a full size format SLR camera, the new zoom lens covers a focal length range from 28mm in wide angle to 300mm ultra telephoto.
When mounted on a DSLR with an APS-C sized imager, the lens covers a range from 43mm wide angle to 465mm equivalent ultra telephoto (full size format equivalent, in a diagonal angle of view of 5°20’). The ratio Tamron uses to convert from full size format to APS-C focal length is 1.55X.
