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, Tamron’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.
