September 1, 2008, Saitama city, Japan- Tamron Co., Ltd (Mr. Morio Ono, President) announced the SP AF10-24mm F/3.5-4.5 Di II LD Aspherical (IF) featuring an unprecedented 2.4X zoom ratio in its class of ultra wide-angle zoom lenses. The innovative, high-performance ultra wide-angle zoom lens (model B001) is designed exclusively for Canon and Nikon digital SLRs with APS-C sized image sensors. Pentax and Sony mount models will be announced at a later date.
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.
* 1 Di (Digitally integrated design)-II lenses are designed for exclusive use on digital cameras with APS-C sized smaller image sensors. Di II lenses are not designed for use with 35mm film cameras and digital SLRs with image sensors larger than 24mmx16mm.
* 2 Tamron’s conversion value is 1.55x
1. 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.
2. Features an Optical Design Optimized for Digital Camera Characteristics
3. 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).
4. Minimum Focus Distance of 0.24m (9.4″)
Across Zoom RangeBecause 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.
5. 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.

Photo Imaging Expo 2008: Tamron showcased their lastest telephoto zoom lens the SP AF 70-200mm F2.8 Di LD [IF] Macro, a constand F2.8 aperture throughout the zoom, a lens anticipated by a lot of amateur photographers. Announced in Canon, Nikon, Pentax and Sony mount the Canon mount is scheduled to be out on 3 April 2008 first released in Japan following by other mounts. We first introduced this lens during KLPF 2007: Tamron SP AF70-200MM F/2.8 DI LD (IF) MACRO.

AF18-200mm F/3.5-6.3 XR Di II has been highly valued since it’s high power zoom provides the convenience of handling many photographic scenes without changing lenses.*Di (Digitally integrated)-II lenses are designed for exclusive use on digital cameras with smaller-size imagers. This lens is not designed for use with 35mm film cameras or digital SLR cameras with image sensors larger than 24mm x 16mm.

Tamron Announces the Launch of SP AF70-200mm F/2.8 Di LD (IF) MACRO (Model A001), a lightweight, high-performance and fast tele-zoom realizing 0.95m (ft) MOD over the Entire Zoom Range
Mr. Morio Ono, President of Tamron Co., Ltd., has announced the launch of SP AF70-200mm F/2.8 Di LD (IF) MACRO (Model A001), a lightweight, high-performance and fast tele-zoom lens designed for DSLR cameras with 35mm full-size image sensors.The new SP AF70-200mm Di LD (IF) MACRO (Model A001) is an F/2.8 fast tele-zoom designed for DSLRs with 35mm full-size image sensors, inheriting product concept of the existing SP AF28-75mm F/2.8 XR Di (Model A09) that is highly acclaimed as a compact and fast standard zoom lens enabling photographers to enjoy high cost performance characteristics.
While dimensional increases are confined to the absolute minimum, the new SP AF70-200mm F/2.8 Di LD (IF) MACRO zoom lens offers the MFD (minimum focusing distance) of 0.95m over the entire zoom range for the maximum macro magnification ratio of 1:3.1 at f=200mm focal length, for stress-free photography, combined with the advantage of an internal focusing (IF) system.
It enables the user to cover a focal length range of 70mm medium telephoto to 200mm telephoto when mounted on a 35mm full-size DSLR camera and a focal length range from 109mm to 310mm equivalent* ultra telephoto (35mm equivalent, in an angle of view of 7°59′) when mounted on a DSLR camera equipped with an APS-C sized image sensor.
(*) Tamron’s conversion ratio is 1.55x.
1. 0.95m MFD over the Entire Zoom Range for 1:3.1 Maximum Magnification Ratio
This zoom lens, designed for use with full-size format SLR cameras, boasts a fast maximum aperture of F/2.8, yet it allows close-focusing down to 0.95m over the entire zoom range. The maximum magnification ratio is 1:3.1 at the 200mm tele-end. The filter diameter is confined to ?ó77mm as a result of the use of an advanced optical design pursuing optimum optical power distribution.
2. Soft Out-of-Focus Effect and Sharp Depiction
In order to realize soft out-of-focus effect and sharp depiction performance at the same time, the zoom lens uses three LD (low dispersion) elements. As a result, the optical system effectively compensates for lateral and on-axis chromatic aberrations that are major image-degrading factors in telephoto photography, in order to provide edge-to-edge sharpness and high-contrast image quality with flat-field characteristics over the entire zoom range in various photographic situations.
3. Lightweight, yet Fast F/2.8 Maximum Aperture
The lens features a fast maximum aperture of F/2.8, yet it weighs a mere 1,112.6 grams (39.2oz.), since it uses barrel parts made of engineering plastic materials having excellent dimensional stability and sufficient strength for professional use and even industrial applications.
4. Internal Surface Coatings Minimize Ghosting and Flare
Through the use of “Internal Surface Coatings (i.e., multiple-layer coatings on cemented surfaces of plural elements) and multiple-layer coatings to prevent reflections from lens surfaces, ghosting and flare due to reflections that occur when light enters through the front element as well as reflections caused by the imager itself in the mirror box are reduced to the absolute minimum.
5. One-touch AF/MF Switchover Mechanisms (for Canon and Nikon only)
The models for Nikon and Canon cameras are equipped with AF/MF switchover mechanisms to allow one-touch switchover from AF mode to MF mode or vice versa electronically and mechanically by simply sliding the button. (Sony and Pentax systems require AF/MF switchover operation on both the camera and lens.)
Since the lens uses an IF (internal focusing) system, the focusing ring does not rotate during focusing, which ensures good holding balance at all times. In the MF mode, focusing is performed as easily and comfortably as with an MF lens. Since the overall length of the lens does not change due to zooming or focusing, it offers excellent operability and holding balance.
6. Detachable Tripod Grip Ring
The lens is supplied with a lightweight and rigid aluminum removable tripod socket.
7. Flower-shaped Lens Hood
A 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.
