June 17, 2008: Tamron has announced the introduction of two new lenses – the AF28-300mm F/3.5-6.3 XR Di VC LD Aspherical (IF) Macro (Model A20N II) lens (pictured right) and the Tamron SP AF28-75mm f/2.8 XR Di LD Aspherical (IF) Macro lens.

The AF28-300mm F/3.5-6.3 XR Di VC LD Aspherical (IF) Macro (Model A20N II) lens is a high power zoom lens compatible with 35mm full-size SLR cameras from Nikon. With a built-in AF motor and featuring Tamron’s proprietary VC system (Vibration Compensation), the new lens is especially suited to the new Nikon D60 and D40 cameras, both of which require lenses with built-in motors.

Tamron’s AF28-300mm VC zoom lens covers an angle of view equivalent to that of a 450mm ultra telephoto lens when mounted on a Nikon digital SLR. The lens covers an angle of view equivalent to 42mm at its wide-angle end on a Nikon DSLR.

The lens covers everything from 28mm wide-angle to 300mm ultra telephoto when mounted on a 35mm film SLR camera. On an APS-sensor Nikon DSLR the focal length is equivalent to 42mm wide-angle to 450mm ultra telephoto (when mounted on a digital SLR camera equipped with an APS-C sized image sensor, 35mm format equivalent – Tamron’s conversion value 1.50x applies.)

The AF28-300mm Di VC sports a minimum focus distance of just 49 cm over the entire zoom range, a best-in-class capability of ultra-zoom zoom lenses suitable for 35mm full-size SLR’s. The maximum magnification ratio of 1:3 at the 300mm telephoto end of its range is also the best available in a lens of this type.

Tamron has employed multi-layer coating on lens elements to reduce reflections from the surface of the lens. Internal surface coatings (coatings on cemented surfaces of lens elements) have also been used to minimise reflections in the mirror box from the imaging sensor in digital SLRs, a problem inherent to digital SLR cameras.
