KLPF: Tamron SP AF70-200MM F/2.8 DI LD (IF) MACRO

KLPF (Kuala Lumpur Photography Festival) 2007- Tamron showcased their newest product, the Tamron SP AF70-200MM F/2.8 DI LD (IF) MACRO. This lens was announced by Mr. Morio Ono, President of Tamron Co., Ltd. at the beginning of the year, a short interview with the Ms Jaimie Yap, a representative from Futoromic Photo- Exclusive distributor of Tamron Malaysia, indicated that this lens shall begin shipping at the end of the year. When asked if it shall be on shelf on December 2007, we did not get a confirm answer.

We were only able hold and look around its exterior and examine the built as it was a pre-production unit and not 100% working, therefore no sample image was taken.  However, Ms Jaimie was kind enough to let us have a few shots of the lens out of the glass shelf. The lens feels solid and weighs around like a Sigma 70-200 F2.8 non Macro. Until a sample unit is given for testing, enjoy the photos of the lens at the moment.

Tamron SP AF70-200MM F/2.8 DI LD (IF) MACRO
press release

A LIGHTWEIGHT, HIGH-PERFORMANCE AND FAST TELE-ZOOM

FEATURING A 0.95M
(37.4”) MFD OVER THE ENTIRE ZOOM RANGE

 

Mr. Morio Ono,
President of Tamron Co., Ltd., has announced the development of the SP
AF70-200mm F/2.8 Di LD (IF) MACRO, a lightweight, high-performance and fast
tele-zoom lens designed for SLR cameras with full-size image sensors.

 

The new SP
AF70-200mm Di LD (IF) MACRO (Model AA001) is an F/2.8 fast tele-zoom designed
for full-size format SLR cameras. It inherits the product concept of the
award-winning SP AF28-75mm F/2.8 XR Di (Model A09) standard zoom lens that is
highly acclaimed for its compactness and speed, which lets photographers enjoy
a high cost to performance uniqueness.

 

While overall
dimensions are confined to the absolute minimum, the new SP AF70-200mm F/2.8 Di
LD (IF) MACRO zoom lens is packed with features that allow stress-free photography:
a versatile MFD (minimum focusing distance) of just 0.95m (37.4”) over the
entire zoom range; an excellent maximum macro magnification ratio of 1:3.1 at
f=200mm; and an advantageous internal focusing (IF) system. The new tele-zoom
lens enables the user to cover a desirable focal length range of 70mm medium
telephoto to 200mm telephoto when mounted on full-size format SLR cameras and a
focal length range from 109mm to 310mm equivalent* ultra telephoto (7°59’ angle
of view) when mounted on a DSLR camera with an APS-C sized imager.

(*) The ratio Tamron
uses to convert from full-size to APS-C focal length is 1.55X.




 

MAIN FEATURES

 

1. 0.95m (37.4”)
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 (37.4”) over the
entire zoom range. The maximum magnification ratio is 1:3.1 at the 200mm
tele-end. The filter diameter is confined to Ø77mm 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.

*As of February
2007, based on Tamron’s research of lenses in the same class, excluding the
tripod base.

 

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
