Tamron has a new lens, the AF18-270mm F/3.5-6.3 Di II VC LD Aspherical (IF) MACRO, touting 15x zoom equivalent to 28-419mm when used with APS-C sized image sensors.
The VC designation stands for Vibration Compensation, Tamronâ€™s version of image stabilization. Di (Digitally integrated) II lenses employ optical systems designed for exclusive use on digital SLR cameras equipped with smaller sized (APS-C sized) image sensors. Di II lenses are not designed for use with 35mm film cameras or digital SLR cameras with image sensors larger than 24mm x 16mm. (IF = Internal Focusing, LD = Low Dispersion)
The 18-270mm Di II VC allows close focusing down to 0.49m (20 inches) from the subject with a maximum magnification ratio of 1:3.5.
Tamron says the new lens will be available for Nikon and Canon mounts.
