When mounted on a PENTAX digital SLR camera body, this 2.7x zoom lens covers angles of view from 76.5mm to 207mm (in 35mm format). Coupled with a large maximum aperture of f/2.8, it is a perfect telephoto zoom lens for applications such as portraiture, featuring beautifully constructed, out-of-focus backgrounds, and sports photography freezing split-second action at high shutter speeds.
Incorporating three ED (extra-low dispersion) elements, this telephoto zoom lens effectively minimises the chromatic aberrations which would be particularly detrimental to image-forming performance.
This telephoto zoom lens is treated with PENTAX-original ghostless coating to effectively minimise internal reflections in the optical elements and greatly improve contrast and clarity with backlit subjects.
