Incorporating large, 42mm diameter objective lenses in a dependable, waterproof body, the Pentax SD 7x42 ED Binoculars deliver a sharp, high-contrast image even in low light conditions. They also incorporate ED (Extra-low Dispersion) optical elements for effective compensation of chromatic aberration to deliver a clear view of the image field.
Bright, clear viewing
Pentax SD models provide sharp, high-contrast images with minimal glare and ghost images, thanks to the application of a full multi-coating
process to all lens surfaces and a special coating designed to optimize light transmittance. They also feature large, 42mm diameter objective lenses to deliver a bright, clear view. The PENTAX SD 7x42 ED feature a large 6mm exit pupil, making it ideal for astronomical observation.
ED optical elements
As the first PENTAX S-series models to incorporate ED (Extra-low Dispersion) optical elements for effective compensation of chromatic aberration, these binoculars deliver a sharp, high-contrast, blur-free image of the subject.
Waterproof construction
Thanks to their dependable waterproof construction (equivalent to JIS Class 6 standards for
watertight designs submersible to a depth of one meter), these SD models can be used in al-most all weather conditions, and can be easily rinsed clean with water. The nitrogen-filled design prevents the interior lens surfaces from fogging caused by sudden temperature changes.
Other features include:
- Exterior housing made of thermoplastic elastomer resin to improve holding comfort and

- Easy-to-operate diopter adjustment mechanism with a nonslip, ring-type adjuster
