This ultra wide-angle zoom lens for digital SLR cameras, with the first-ever focal length range of 10-24mm the 35mm equivalent of 16mm ultra wide-angle to 37mm semi-wide-angle-is a perfect tool for creating dramatic landscape, cityscape, and seascape imagery. At the ultra wide-angle setting, you'll be able to capture vistas beyond what the eye can see. At the semi-wide-angle setting, you'll capture scenes with angles of view almost as spectacular. (Nikon mount has built-in motor for D40/D40x/D60).
Di II: Lenses are designed for exclusive use on digital cameras with smaller-size imagers and inherit all of the benefits of our Di products. These lenses are not designed for conventional cameras and digital cameras with image sensors larger than 24mm x 16mm.
TAMRON DEVELOPS SP AF10-24MM F/3.5-4.5 DI II LD ASPHERICAL (IF) (MODEL AB001)
A New High Performance Zoom Lens Designed for Exclusive Use on Digital SLR Cameras Covering the Ultra Wide-Angle Range
PMA, January 31, 2008, Las Vegas, NV— Mr. Morio Ono, President of Tamron Co., Ltd., announced the development of the SP AF10-24mm F/3.5-4.5 Di II LD Aspherical (IF) (Model AB001), a new high performance ultra wide-angle zoom lens designed exclusively for digital SLR cameras with APS-C size imagers.
* Di –II “(Digitally-Integrated design)” lenses are designed for exclusive use on digital cameras with smaller-size imagers.
* This lens is not designed for use with 35mm film cameras and digital SLR cameras with image sensors larger than 24mm x 16mm.
The new SP AF10-24mm F/3.5-4.5 Di II LD Aspherical (IF) is an advanced ultra wide-angle zoom lens that is versatile and offers even higher performance and specifications than the current Tamron SP AF11-18mm F/4.5-5.6 zoom lens.
The lens covers an extended focal length range that is particularly wide for an ultra wide-angle zoom lens, while improving the aperture to F/3.5-4.5 and keeping the filter diameter to 77mm. Its lightweight and compact size makes this new wide-angle zoom very user friendly.
The lens was designed for use with digital SLR cameras and thereby employs special optical glass materials for outstanding optical performance such as large-aperture glass-moulded aspherical elements and hybrid aspherical elements.
1. Compact Ultra Wide-angle Zoom Lens Covering a Broad Range from 10mm to 24mm The Tamron zoom covers a focal length range equivalent to 16-37mm* when converted to a 35mm full-size format. Its ultra-wide zoom ratio of more than 2X provides a versatile variety of angles of view, thus improving photographic creativity.
*Tamron’s conversion ratio is 1.5x.
2. Features an Optical Design Optimized for Digital Camera Characteristics Ensures High Optical Performance
(a) Employment of Special Optical Glass Materials Provides High Performance The zoom lens uses an HID glass element and a pair of LD glass elements to minimize on-axis and lateral chromatic aberrations that are the greatest hindrance to high optical quality. To further achieve outstanding optical quality, the lens uses a high quality, glass-moulded aspherical element and three hybrid aspherical elements to thoroughly compensate for spherical and chromatic aberrations and distortion.
(b) Optical Design Optimizes the Angles of Incidences of Light Rays Reaching the Imager The 10-24 ultra wide zoom lens uses a 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, by considering the effects of variances due to zooming.
(c) Enhanced Peripheral Illumination Peripheral light fall-off is minimized so that images are high quality from the center to the periphery.
(d) Outstanding Resolution As an SP Di II class lens, it provides high optical quality in terms of resolution, contrast and flatness of image field.
(e) Internal Surface Coating Reduces Ghosting and Flare The lens uses a newly developed multiple coating and internal surface coating, (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.
3. Ultra Compact and Lightweight Design The 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. Despite higher specifications that are likely to incur a bulky design, the new zoom lens is lightweight and compact. Tamron has successfully realized a versatile ultra wide-angle zoom lens that is lightweight and compact enough in overall length and diameter to accept a 77mm filter, the same as the existing SP AF11-18mm zoom lens.
4. Minimum Focus Distance of 0.24m throughout the Entire Zoom Range Considering the importance of “close focusing capability” as an essential condition in wide-angle photography, Tamron has achieved a 0.24m minimum focus distance over the entire zoom range. Getting closer to the subject allows you to easily express a more creative photographic vision.
5. Flower-shaped Lens Hood A glare-reducing flower-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.
6. New External Design Conveying “High Performance, High Precision Image” on the Basis of Tamron’s Conventional Lens Design The external design is improved to enhance the uniformity and smoothness. The metallic finish of the gold band of Tamron lenses makes it stand out as a Di II lens, while the layout of alphanumerical markings is improved for better visibility. The rubber patterns of the zoom and focus rings have also been improved to compliment today’s digital camera design style and to provide better handling.
