As with the Tamron 10-24mm the 90mm f/2.8 Macro has been updated to include a built-in motor for the Nikon mount in order to accommodate the Nikon D40, D40x and D60, which do not have an AF motor in the body of the camera.
Press Release
Tamron Co., Ltd (Mr. Morio Ono, President) has successfully renewed the existing SP AF90mm F/2.8 for Nikon and is now pleased to announce the availability of the lens with a built-in AF motor for Nikon. (The lens is already available in mounts for Canon, Pentax and Sony.)
Tamron’s SP 90mm lens has been highly evaluated by photographers all over the world not only as a high-performance macro lens but also as a medium telephoto lens suitable for all photographic applications including landscape and portraiture. The SP 90mm F/2.8 macro lens, first introduced in 1979, underwent a major model change in 2004 to feature a Digitally Integrated (Di) design while retaining its renowned optical performance
MAIN FEATURES
1. Outstanding Image Quality by Virtue of “Di” (Digitally Integrated) Design
The lens provides outstanding image quality whether the medium in use is silver halide (film) or a digital image sensor, since it features Tamron’s “Di” optical system designed to meet the performance characteristics of digital cameras as well as film cameras.
2. Features Coatings Optimized for Digital Photography
One major difference between digital cameras and film cameras is how internal reflections in mirror boxes may occur and to what extent. These internal reflections can cause unwanted flare or ghosting on the final image. In a film camera, internal reflections can be caused inside the mirror box of the camera or from light reflecting off the film surface. In a digital camera, stronger reflections can occur from light bouncing off the sensor, since CCD and CMOS sensors are almost mirror-like on their surface, making the problem more noticeable. The SP AF90mm F/2.8 Di lens features an improved coating technology that reduces to the absolute minimum the reflections that are likely to cause this issue.
3. Angle of View Ideal for Film and Digital Photography
The SP AF90mm lens offers a medium telephoto focal length making it particularly useful as a portrait/macro lens when used with a full-size sensor or film camera. When used on a digital SLR camera (with an APS-C sized image sensor), the lens provides an angle of view equivalent to that of 140mm (35mm-equivalent), so it can be used conveniently as a telephoto macro lens for digital photography.
4. Lightweight and Compact Design
The SP AF90mm is a 1:1 life-size macro lens for which outstanding optical performance is required, yet it uses engineering plastic materials for its barrel parts. As a result, the lens is the most lightweight medium telephoto lens* among 1:1 life-size macro lenses in the AF90-100mm class, realizing portability and high image quality at a superior level.
* Weight value of Nikon AF-fit model compared to other makes
5. AF/MF Switchover in Single Action
The lens features a mechanism to allow speedy AF/MF switchover in a single action. The rubber pattern on the intentionally wide focus control ring ensures a better grip, making use comfortable since macro lenses are frequently used in the manual focusing mode.
