Main Features

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

  • 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.

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.

 

6. 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.

Tamron AF18-270mm F/3.5-6.3 Di II VC LD Aspherical (IF) MACRO (Model B003)

With its vast zoom-range, the Tamron AF18-270mm F/3.5-6.3 Di II VC lens enables the user to cover virtually any photographic subject from wide angle to ultra telephoto simply by turning the zoom control. It covers angles of view equivalent to 28mm to 419mm when converted to the 35mm format. In addition, this breakthrough lens is equipped with Tamron’s exclusive, proprietary tri-axial Vibration Compensation (VC) mechanism that eliminates or substantially reduces the effects of handheld camera shake. As a result, the user can enjoy the convenience of handheld photography in virtually any situation, from shooting candid images, to covering sporting events, to news photography, without worrying about camera shake having an adverse effect on image quality. The new lens will be made available in Canon and Nikon mounts. The price and launch date of the new lens will be announced at a later date. 

* 1 “The world’s longest zoom range” and “world’s first” are statements that apply to interchangeable lens exclusively designed for digital SLR cameras equipped with APS-C sized image sensors, as of June 2008, according to Tamron’s survey.

* 2 Tamron’s conversion value is 1.55X

Note: Di (Digitally integrated) II lenses employ optical systems designed for exclusive use on digital SLR cameras equipped with smaller sized (APS-C sized) image sensors. Di II lenses are not designed for use with 35mm film cameras or digital SLR cameras with image sensors larger than 24mm x 16mm. (This special note “APS-C sized image sensors” is hereinafter omitted.)

 

Development Background

Since launching the Tamron AF28-200mm F/3.8-5.6 (Model 71D) in 1992 that was highly acclaimed as the first high power zoom lens suitable for practical use, Tamron has continued to develop innovative zoom lenses as the “pioneer in high power zoom lenses”. With the AF18-200mm F/3.5-6.3 XI Di II (Model A14), Tamron realized an 11.1X zoom power for the first time in a zoom lens exclusively designed for digital SLR cameras and expanded the telephoto range further to 13.9X with the AF18-250mm F/3.5-6.3 Di II (Model A18), making steady progress in extending the range of high performance, high power zoom lenses.

 

Tamron’s engineers faced the even more formidable challenge of finding solutions for the problem of “handheld camera shake” while expanding the telephoto range even further and have eventually developed the AF18-270mm F/3.5-6.3 Di II VC. This lens has attained the maximum zoom power of 15X for the first time in the world, namely as a zoom lens exclusively designed for digital SLR cameras. It enables the user to cover an extremely wide angle-of-view range equivalent to a 28mm-419mm lens in the 35mm format. In addition, the lens is equipped with Tamron’s original and exclusive VC mechanism that effectively compensates for “handheld shake”, which would otherwise become visible as un-sharpness or blur in images shot handheld.

 

Moreover this system is effective over the extremely wide focal length range of this extended ultra telephoto lens and Tamron’s VC mechanism provides maximum compensation performance at all focal lengths. The VC system enables the user to enjoy the full benefits of ultra-tele photography comfortably and provides amazingly stabilized viewfinder images as well. In short, this unique VC image stabilization system delivers the maximum potential built into the world’s longest-ratio zoom lens-15X.

 

Tamron was able achieve all these remarkable accomplishments thanks to its advanced optical / mechanical design technologies and production know-how accumulated over 16 years as the pioneer in high power zoom lens design, and its commitment to ongoing research and development. Even more important, in combining an amazingly high zoom ratio along with the VC function Tamron has maintained a high priority on its traditional goals of lightness and compactness. As a result the new Tamron AF18-270mm Di II VC delivers all the functionality and performance you expect from the latest Tamron ultra high power zoom, a lens that exemplifies our time-honored concept of “One great lens covering everything from wide angle to telephoto”.

 

Main Feature

1. World’s first and greatest zoom ratio of 15X, covering 28-419mm 35mm-equivalent angle of view

Going back to the basic concept of “one lens covering everything from wide angle to telephoto,” engineers at Tamron took up the difficult task of expanding the zoom range of Tamron’s high power zoom lenses even further. Their unstinting efforts to extend the telephoto end beyond previous limits while retaining the wide-angle end at 18mm has borne fruit as an ultra high power zoom lens that is exclusively designed for DSLR cameras and boasts the greatest zoom range of 15X for the first time in the world.

 

2. Tamron’s original VC mechanism for effective shake-free hand-held photography

Tamron’s proprietary VC (Vibration Compensation) mechanism was built in the AF28-300mm F/3.5-6.3 Di VC (Model A20) for the first time. It demonstrated its powerful compensation effect employing a tri-axial system that is designed to let three coils drive a compensator lens electromagnetically via three steel balls. Since the compensator lens is supported on rolling steel balls with very low friction, follow-up performance is also enhanced, resulting in stabilized viewfinder images. Since the mechanism is designed to allow parallel shifting of the compensator lens solely by means of electrical control, the mechanical construction is simpler and more compact, so the lens can be kept as a small and light as possible.

 

3. Designing a high power, compact zoom lens with VC mechanism: Optical design optimization meets optimum power distribution

In developing the long-range zoom lens, Tamron’s optical designers pursued the optimum distribution of power within the overall optical system based on the optical design know-how Tamron accumulated over 16 years since the introduction of the first compact AF28-200mm in 1992. The resulting optical system uses three hybrid aspherical elements, two LD (Low Dispersion) glass elements and an AD (Abnormal Dispersion) glass element in order to effectively compensate for various aberrations including astigmatism and chromatic aberration, yet this design allows the first optical group to be small enough in diameter to realize the overall goal of a compact lens that incorporates a handheld-shake compensation mechanism.

 

Note: In order to realize the high zoom ratio of 15X, the optical system does not use any XR (extra dispersion glass) element. Instead, compactness is achieved through optimization of the power distribution within the whole optical system.

 

4. Minimum focusing distance of 0.49m over the entire zoom range for the maximum magnification ratio of 1:3.5

The AF18-270mm Di II VC allows close focusing down to 0.49m (20 inches) from the subject over the entire zoom range even though it incorporates the VC mechanism. The maximum magnification ratio of 1:3.5 at its 270mm telephoto end is the top class capability among high power zoom lenses exclusively designed for digital SLR cameras.

* 3 A format covered by an APS-C sized image sensor is smaller than that of 35mm format film. Therefore, this lens is capable of filling the frame by capturing an area that is almost the same as an area covered by a lens designed for the 35mm format and providing the maximum magnification ratio of 1:2.3.

 

5. Optical system optimized for digital SLR cameras by taking incident rays of light reaching the image sensor into consideration

In order to effectively compensate for changes in aberrations due to zooming, the zoom lens employs an innovative optical system that is designed to converge the angles of rays of light entering from the center to the periphery of the lens. The light rays thus reach the image sensor within a defined circle that assures high imaging performance and reduces light falloff.

 

6. High resolution performance

As a lens exclusively designed for digital SLR cameras, this zoom lens delivers high resolution and contrast performance for outstanding image quality with sufficient flatness of the field under an extremely wide range of photographic conditions.

 

7. Thorough countermeasures, including advanced internal surface coatings, prevent ghosting and flare

Tamron employs multi-layer coatings in order to reduce reflections on lens surfaces as well as internal surface coatings (coatings on the cemented surfaces of lens elements) in order to minimize reflections from the sensor itself within the mirror box, a problem inherent to all digital SLR cameras.

 

8. The world’s first and greatest zoom power of 15X plus built-in VC mechanism achieved along with a remarkably slim maximum diameter of less than 80mm

Designing a lens with the world’s first and greatest zoom ratio of 15X inevitably entailed a larger travel distance of the components within the optical systems, but Tamron has successfully accommodated the optical system as well as the special VC mechanism in a remarkably compact and slim package by employing mechanical design technology accumulated over many years. The result: A slim design measuring less than 80mm in diameter despite the fact that it is an ultra high power zoom lens that incorporates a VC mechanism. Production engineering this unique zoom lens meant incorporating complex optical / mechanical components, and Tamron’s engineers had to employ innovative manufacturing techniques including methods of further enhancing accuracy, reducing weight, and increasing the strength of many components.

Note: : In order to achieve the world’s first and greatest zoom ratio of 15X, metal mounts are used in both Canon- and Nikon-mount lenses.

 

9. Zoom lock mechanism for convenience in carrying the outfit

The lens has a built-in zoom lock mechanism to prevent its barrel from sliding forward when the lens is being carried on the camera.

 

10. Flower-shaped lens hood as a standard accessory

The lens is supplied with a flower-shaped lens hood as a standard accessory. It is designed to efficiently cut harmful light entering at angles other than intended angles at all four corners of the frame. This ensures clear, flare-free images.

 

11. New outer design matches the newest generation high power zoom lens in the digital era

  • The lens employs a new outer design that is more refined and smoother in its overall contours by minimizing concavity, convexity, and variations in profile in order to match the latest digital SLR cameras.
  • A gold-colored metal ring is placed at a key portion of the lens as used in other Di II lenses. The “TAMRON” logo placed in the center portion of the lens enhances visibility of the brand while refining the overall design.
  • Delicate matte finish is added to the black painting over the lens barrel in order to enhance the high quality appearance of the lens.
  • The textured rubber pattern of the zoom and focus control rings has been improved again to a more pronounced, easy to grasp design than the conventional rubber pattern, for better feel and touch in manipulating the lens.

Tamron Announces the Launch of SP AF70-200mm F/2.8 Di LD (IF) MACRO (Model A001)

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.


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 ?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.
