SD 9X42

The Pentax SD 9x42 WP offers fully multi-coated lenses with anti-reflection properties that maximize light transmission through the entire optical path. Phase-corrected roof prisms ensure a bright, high-contrast image with faithful color rendition even in low light. The 9x magnification brings subjects a bit closer than the common 8x while reducing visible shake, and the nitrogen-filled housing is fogproof and submersible.
