This new generation design has all the good things PENTAX has delivered for many years in popular standard-size binoculars. With the DCF CS we are setting new optical standards. This binocular impresses in brightness, clarity and overall image quality. The DCF CS range is clearly a light-weight: only 615 grams on a full-size 10 x 42 binocular is unbelievable, almost sensational. When weight is a critical factor for you, the DCF CS is the perfect reason to upgrade to full size.
