Tamron 28-300mm F/3.5-6.3 XR Di VC LD Aspherical (IF) Macro Lens

Equipped with Tamron’s proprietary Vibration Compensation Mechanism -Tamron Vibration Compensation (VC) mechanism.

The AF28-300mmF/3.56.3XR Di VC is the ultimate high power zoom lens that covers everything from wide angle to telephoto and macro.

Tamron has incorporated a proprietary Vibration Compensator, an antishake mechanism developed by Tamron, into the highly versatile zoom lens.

The new AF28-300mmF/3.5-6.3 XR Di VC LD Aspherical (IF) MACRO zoom lens offers the convenience, comfort andversatility of a high power zoom lens and the capability to reduce handshakeblur on SLR cameras using either APSCsize or full size format imagers.

When the AF28-300mmF/3.56.3XR Di VC is used with a full format SLR camera, it covers the tremendous focal length range from 28mm in wide angle to 300mm ultra telephoto.

When mounted on a DSLR with an APSC sized sensor, the lens covers 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 APSC focal length is 1.55X.

MAIN FEATURES:

VC (Vibration Compensation) Mechanism Reduces Effects of Handheld Image Shake

The proprietary VC (Vibration Compensation) mechanism developed by Tamron features a triaxial configuration, using three pairs of driving coils and slide balls around the compensator group of the lens' optical system. Since the compensator lenses are supported with rolling friction of the ball mechanisms, performance is enhanced.

Construction is simpler, which results in an ultra compact lens for its focal range. The lens incorporates a highly accurate gyro sensor for detecting handheld image shake. This combines with a 32bit RISC processor to offer the photographer a highly effective antivibration effect.

Outstanding Design Realizing High Zoom Power, VC Mechanism and Compactness

The AF28300mm F/3.56.5 XR Di VC integrates optical technologies Tamron hasaccumulated as the pioneer and leader in high power zoom lenses together with compactness, even with the addition of the Vibration Compensation mechanism.

The optical system uses a number of lens elements made from special optical glass materials including XR (high refraction index) glass elements, GM (glass molded Aspherical lens) elements, hybrid aspherical elements, LD (low dispersion) glass elements to compensate for on axis and lateral chromatic aberrations and an AD (anomalous dispersion) glass element. The lens offers high contrast, high resolution performance and flatness of the image field as a one does it all zoom lens, designed to optimally match the characteristics of DSLR cameras.

Revolutionary Minimum Focusing Distance of 0.49m (19.3") throughout the Zoom Range Provides 1:3 Macro Magnification Ratio

The AF28300mm F/3.5-6.3 XR Di VC LD MACRO lens boasts a MFD (minimum focusing distance) of 0.49m (19.3") over the entire zoom range. This ranks it as a top class close focusing lens capability among high power zoom lenses for full size format SLR cameras, a remarkable maximum macro magnification ratio of 1:3 at the 300mm telephoto end is achieved.

Internal Surface Coatings Minimize Ghosting and Flare

Internal Surface Coatings (i.e., multiple layer coatings on cemented surfaces of multi elementlens groups) and multiple layer coatings prevent reflections off lens surfaces,reducing ghosting and flare that occur when light enters through the front element. These coatings also reduce reflections caused by digital imaging sensors in the mirror box of digital SLRs.

Ultrahigh 10.7x Zoom Power, yet Lightweight and Compact Design Tamron has reviewed the roles that respective barrel parts play in order to achieve the high power, compactness and light weight. As a result, dimensional increases are confined to a mere 17.8mm (0.7") in overall length and about 5mm (0.2") in diameter, when compared with the existing AF28-300mm(Model A061). This is despite the incorporation of the VC mechanism.

Zoom Lock Mechanism for Enhanced Portability & Lens Security

A zoom lock is provided that prevents unwanted barrel extension when carrying the lens/camera combination over the shoulder. This avoids the zoom lens mechanism gradually extending downwards while the lens is being carried pointing downwards.

Flowershaped Lens Hood

A flower petal shaped lens hood is included as a standard accessory. The special hood provides optimum shading of superfluous light rays that enter from the rectangular frame outside the image field.
