Tamron is a leading manufacturer of lenses for photographic, industrial, laboratory, video, digital and scientific applications. Tamron Di lenses offer superior features and performance, not only for standard, but also for digital SLR cameras. Di lenses feature high resolution performance and incorporate a new sophisticated anti reflective coating and optical configurations to compensate for internal reflections and ghosting that are attributable to the image sensors. Peripheral light fall off, which is more likely to be noticeable in images taken with digital cameras, is also reduced.
