The SP AF10-24mm Di II, the first-ever ultra wide-angle lens for digital SLR cameras, features a focal length range with the 35mm equivalent of 16mm ultra wide-angle to 37mm semi-wide-angle in a user-friendly lightweight, compact design. With this versatile ultra-wide-angle zoom lens, photographers can capture magnificent vistas and extraordinary close-ups, bold compositions and unique perspectives, creating imagery impossible with standard wide-angle lenses.
The advanced optical system of this ultra wide angle lens features large-aperture, glass-molded aspherical elements, hybrid aspherical elements, as well as elements made of special low-dispersion glass and high-refractive index glass, all of which combine to deliver high-quality imagery and performance.

MAIN FEATURES |
- Covers the Broadest Range Ever-from 10mm Ultra Wide-angle to 24mm-in Its Class.
The new Tamron ultra wide-angle zoom lens covers the 35mm full-size format equivalent of 16-37mm, for the first time in this class of zoom lenses . This focal length range-10mm ultra wide-angle to 24mm semi wide-angle-enables the user to enjoy hassle-free wide-angle photography.
- Features an Optical Design Optimized for Digital Camera Characteristics
- Special Optical Glass Materials for High Optical Performance
The new zoom lens uses a high-precision, large-aperture glass-molded aspherical lens element and three hybrid aspherical elements to minimize spherical aberration, coma, and distortion. In addition, a pair of LD (Low Dispersion) glass elements and an HID (High-refractive Index) glass element together compensate for on-axis and lateral chromatic aberrations, delivering high optical quality.
- Optical System Designed to Optimize Angles of Incidence of Light Rays Reaching the Imager
The new ultra wide-angle zoom lens uses a new optical system designed to confine the changing angles of incidences of light rays reaching the imager within a certain scope over the entire image field, from the center to the periphery, addressing the effects of variances caused by zooming.
- Enhanced Peripheral Illumination
Peripheral light fall-off that becomes an image-degrading factor in wide-angle photography is minimized to ensure high optical quality from the center to the periphery.
- Outstanding Resolution
As an SP Di II class lens, it provides high optical quality in resolution, contrast, and flatness of image field.
- Internal Surface Coatings Reduce Ghosting and Flare
The lens uses newly developed multiple-layer coatings and internal surface coatings (i.e., multiple-layer coatings on cemented surfaces of plural lenses) to reduce the image degradation caused by the reflection of light rays entering from the lens front and affected by the imager.
- Ultra-Compact, Lightweight Design
The new zoom lens covers a wider focal length range with a greater zoom ratio and offers a faster maximum aperture and enhanced optical quality than the existing SP AF11-18mm zoom lens (Model A13). Despite the higher specifications, the new zoom lens is lightweight and compact and accepts a 77mm filter, the same as the existing SP AF11-18mm F/4.5-5.6 Di II zoom lens (Model A13).
- Minimum Focus Distance of 0.24m (9.4") Across Zoom Range
Because a close-focusing capability is essential in wide-angle photography, Tamron engineered a 0.24m (9.4") minimum focus distance across the zoom range. This capability gives the user freedom to create images with an exaggerated perspective at the 10mm ultra wide-angle end and shoot with a maximum magnification ratio of 1:5 at the 24mm semi-wide-angle setting, the largest magnification ratio in its class.

As of August 2008, according to Tamron's research of ultra wide-angle zoom lenses designed for exclusive use on digital SLR cameras. |
- Flower-shaped Lens Hood Is a Standard Accessory
A glare-reducing, flower-shaped lens hood is included as a standard accessory. The special hood provides optimum shading of light rays that enter from the rectangular frame outside the image field.
- New External Design Expressing "State-of-the-Art Ultra Wide-angle Zoom Lens" in the Digital Era
- The new zoom lens features a refined exterior design that enhances its uniformity and smoothness, matching the designs of current digital SLRs.
- The metallic finish of the gold band on Tamron lenses makes it stand out as a Di II lens, and the layout of alphanumeric markings, including the TAMRON logo in the center of the control ring, has been improved for greater visibility.
- Exquisite black mat finish is applied to the black paint over the lens barrel for improved quality appearance.
- The rubber patterns on the zoom and focus rings have been enhanced to compliment today's digital camera design style and ensure better handling.
