Tamron 90mm f2.8 SP Di Macro Lens

The existing Tamron 90mm Macro lens is world renowned for its outstanding optical performance as well as its lightweight and compact design. Tamron have redesigned this lens to feature Di - Digitally Integrated Design for use with film and digital SLR cameras.

The lens provides outstanding image quality when used with film or digital cameras. Unlike conventional lenses, designed to cope with internal diffused reflections of a mirror box and film surface, Di lenses offer new anti-reflection countermeasures that are essential in lenses designed for use with digital cameras. the 90mm Di features an improved coating technology that reduces the reflections that are likely to become a problem to the absolute minimum.

This new 90mm Macro lens also features an improved external design and improved focusing ring. The lens is also equipped with a one touch switchover mechanism to quickly perform one touch switchover from AF to MF by simply sliding the focus ring back and forth (for Nikon AF-D and Canon AF mounts only).

By the employment of an improved design that makes it the most lightweight* medium telephoto macro lens available. The lens weighs 15 grams less and is 2.5mm shorter than the previous model.

*as of January 2004 based on Tamron research of lenses in the same class. The weight values used for comparison are those of Nikon AF-fit lenses.

The 90mm Di lens offers a medium telephoto focal length making it particularly useful as a portrait macro lens when used with a film camera. When the lens is mounted on a digital camera (with an APS-C sized image sensor) it provides a focal length equivalent to that of 140mm, so it can be used conveniently as a telephoto macro lens for digital photography.
