PENTAX-DA 50-135mm F2.8 ED [IF] SDM is a 2.7X zoom lens covering angles of view from 76.5mm to 207mm (in the 35mm format). PENTAX-DA 50-135mm F2.8 ED [IF] SDM is ideal for the portrayal of beclouded, out-of-focus backgrounds and sports photography freezing split-second action because of its large maximum aperture of F2.8. This telephoto zoom lens integrates three ED (extra-low dispersion) elements to effectively minimize the chromatic aberrations which damage image-forming performance. Ghostless coating on the telephoto zoom lens effectively minimizes internal reflections in the optical elements. The smc PENTAX-DA 50-135mm F2.8 ED [IF]SDM will be made available in Spring for US $999.95.
