With Extra-low Dispersion (ED) glass lens element and
two aspherical lens elements, the lens offers more true-to-life image
reproduction. 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.
