Tamron SP AF70-200mm F/2.8 Di LD (IF) Macro

Tamron announced yet another lens at this year's PMA show, the SP AF70-200mm F/2.8 Di LD (IF) MACRO. This fast telezoom gets in close thanks to its 0.95m minimum focus distance, realizing a magnification ratio of 1:3.1 at 200mm. Plenty of coatings keep stray light to a minimum whilst a removable tripod mount and clutched focus ring (Canon and Nikon only) help speed up operations. Canon users will see the lens first with release scheduled for March. Nikon, Sony and Pentax fittings will follow.

The new SP AF70-200mm Di LD (IF) MACRO (Model AA001) 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.

Main features

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 φ77mm 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.

Tamron developing 10-24mm f/3.5-4.5

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 (Digitally-Integrated design)-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 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-molded aspherical elements and hybrid aspherical elements.

Main Features

Compact Ultra Wide-angle Zoom Lens Covering a Broad Range from 10mm to 24mm
The new 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.

Features an Optical Design Optimized for Digital Camera Characteristics Ensures High Optical Performance

1. Employment of Special Optical Glass Materials Provides High Performance The new 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-molded aspherical element and three hybrid aspherical elements to thoroughly compensate for spherical and comatic aberrations and distortion.
   HID – High Index/High Dispersion optical glass
   LD – Low Dispersion optical glass
2. Optical Design Optimizes the Angles of Incidences of Light Rays Reaching the Imager The ultra wide 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, by considering the effects of variances due to zooming.
3. Enhanced Peripheral Illumination Peripheral light fall-off is minimized so that images are high quality from the center to the periphery.
4. Outstanding Resolution As an SP Di II class lens, it provides high optical quality in terms of resolution, contrast and flatness of image field.
5. 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.

Ultra Compact and 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. 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.

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.

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.

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.
