Product Description
Designed for exclusive use with PENTAX KAF-mount digital SLR cameras, the new
lens offers 4X zoom coverage in the telephoto range. Further, the lens features
an angle of view from 31.5 degrees to 8.1 degrees (equivalent in focal length
from 76.5mm to 306mm in the 35mm format).
As with all DA-Series lenses, this DA 50mm-200mm features a responsive
Quick-Shift Focus System that allows photographers to instantly switch the focus
mode from auto to manual with a slight twist of the focus ring. Coupled with a
simple, functional design and the elimination of an aperture ring, this new
mechanism considerably improves operability.
The lens also incorporates an Extra-low Dispersion (ED) glass lens element
and two aspherical lens elements for true-to-life image reproduction and overall
size reduction. The image circle in DA-series lenses is designed to perfectly
match the 23.5mm x 15.7mm size of the CCD used in PENTAX digital SLRs to
optimize camera performance.
The new design also contributes to a drastic reduction in size, weight and
production cost, compared to 35mm-format counterparts with similar
specifications.
And its weather-resistant, so you can keep exploring even in damp, inclement
conditions. |
