To coincide with the launch of Pentax?s flagship SLR, the manufacturer has also unveiled an interchangeable medium-telephoto lens. Designed for Pentax Digital SLRs, the smc Pentax-DA 70mm F2.4 Limited features an ultra-thin pancake design and uni-focal, medium-telephoto optics.
Thin, lightweight design
Thanks to newly developed optics, the medium-telephoto lens measures 26mm and weighs in at 130 grams. When mounted on a Pentax digital SLR body, it protrudes only a short distance from the camera’s front panel and offers a focal length equivalent to 107mm in 35mm format.
Distinctive visual description:
The Pentax Limited Lens series is designed for distinctive visual description by combining a series of mechanical and numerical evaluations with human assessment of test-shooting samples. As a result, Pentax claims that the lens will produce smooth, natural skin tones and out-of-focus backgrounds at open aperture during portrait shooting.
The lens barrel, hood and cap are made from high-grade aluminum, shaped for optimum proportions and aesthetic appeal. The focusing ring is designed for accessibility and ease of focusing.
A Pentax-original Super Protect (SP) coating is applied to the front surface of the kens. Through a vapor deposition process, the lens surface is coated with a special fluorine compound to repel dust, water and grease, making it easier to wipe off fingerprints and cosmetics.
Digital SLR-exclusive optical design:
The lens is exclusively designed for use with Pentax digital SLR cameras, with an image circle proportioned to the CCD size (23.5mm x 15.7mm), and optics optimized for digital imaging characteristics.
