Three new Konica Minolta DT lenses

In addition to the announcement of the Maxxum 5D Konica Minolta has also announced three new DT (designed for digital SLR) lenses; the AF DT 18 - 70 mm F3.5 - F5.6 (D), the AF DT 11 - 18 mm F4.5 - F5.6 (D) and the AF DT 18 - 200 mm F3.5 - F6.3 (D).

Press Release:

Konica Minolta introduces new DT series lenses

Lens Overview

As the new standard for digital SLR cameras, DT lenses are ideally suited to digital SLR cameras such as the Maxxum7D/5D and Dynax7D/5D which are equipped with large (23.5 x 15.7 mm) CCDs.

Konica Minolta AF DT Zoom 18 -70 mm F3.5 to 5.6 (D)
Konica Minolta AF DT Zoom 11-18 mm F4.5 to 5.6 (D)
Konica Minolta AF DT Zoom 18-200 mm F3.5 to 6.3 (D)

Lens Features

1. Optimum high-performance optical design for digital SLR cameras

To ensure consistently high quality images, the Dynax5D/Maxxum5D uses an optical system ideally suited to a large (23.5 x 15.7 mm) CCD, in addition to spherical lenses to reduce spherical aberrations, AD (anomalous dispersion) glass, and a special lens coating that reduces flaring that often occurs in digital SLR cameras.

2. Effective Anti-Shake compensation equivalent to a shutter speed 2 - 3 stops slower*1 with Dynax/Maxxum digital SLR camera

3. Distance encoder enables precise ADI flash metering

Using information obtained from the lens' built-in distance encoder, Advanced Distance Integration (ADI) flash metering calculates the optimum exposure settings and flash brightness needed to obtain a beautiful image when using either the internal flash or external flash units such as the Program Flash 5600HS(D) or 3600HS(D), and 2500(D).

4. Circular aperture beautifully enhances defocused images

A round aperture makes it possible to enhance a defocused image with smooth gradations and depict a scene naturally, for example, sunshine filtering through foliage or grass glistening with morning dew.

Note: Dynax/Maxxun DT series lenses are not compatible with conventional 35mm SLR cameras.

*1 The Anti-Shake technology correction effect (in terms of shutter speed exposure steps) varies with the shooting conditions and lens used.
