Features Vibration Compensation for Nikon DX-format DSLRS

• Uncompromising countermeasures to reduce ghosting and flare
The latest BBAR (Broad-Band Anti-Reflection) multi-layer coatings are used to reduce reflection from the lens, ensuring excellent performance in all photographic conditions. The coatings enhance light transmission in both the short wavelength and long wavelength ranges. In addition, internal surface coatings (coatings on cemented surfaces of lens elements) have been applied to all cemented surfaces, for sharpness, optimum color reproduction performance and excellent color balance.

4. Minimum focus distance of 11.4” (0.29m) across the zoom range, with macro capability of 1:4.8
Even with its VC image stabilization optical system this lens delivers a minimum focus distance of 11.4” over the entire zoom range, enabling stress-free close-up photography. The maximum magnification ratio at 50mm is 1:4.8 .

5. Simple, beautiful exterior design
A simple, classic design with a smooth silhouette has been adopted to ensure that this lens combines well with various SLR cameras. The highest quality textured paint has been used to give a superb finish to the exterior.

7. Zoom lock mechanism, useful when carrying the lens/camera over your shoulder
The lens includes Tamron’s zoom lock mechanism to prevent the lens barrel from extending by its own weight when lens is being carried on the camera pointing downward.

8. Flower-shaped hood with excellent stray light shielding properties supplied as standard accessory
The flower-shaped hood is ideally matched to the frame of the viewfinder screen to effectively block damaging light rays coming in from outside the borders of the image area, ensuring clear, sharp flare-free performance. The hood is provided as a standard accessory.
