Pentax launches four binoculars with ultra-low dispersion (ED) lenses: covering the S / A series, 7pm 10x magnification
CTOnews.com, April 24, PENTAX Pentax, a camera brand owned by Ricoh, announced the launch of four binoculars with ultra-low dispersion (ED) lenses:
PENTAX AD 7 × 32 ED (A Series)
PENTAX AD 10 × 32 ED (A Series)
PENTAX SD 7 × 42 ED (S-Series)
PENTAX SD 10 × 42 ED (S-Series)
Pentax AD 7 × 32 ED and Pentax AD 10 × 32 ED inherit the compact, lightweight design of A-series binoculars. In addition to using the same lens coating as the high-end model, an enhanced ultra-low dispersion (ED) lens is added to Series A roof prism binoculars for the first time, which can effectively compensate for chromatic aberration.
Main features:
It uses the same dielectric high-reflection multilayer prism coating technology as the high-end Z series model.
A complete multiple coating process is applied to the surface of all lenses, and a special coating is used to optimize the light transmittance.
The first model in the Pentax A series uses ultra-low dispersion (ED) optical lenses to compensate for color aberration.
An objective lens with a diameter of 32 mm is adopted, which is easy to carry in a variety of application scenarios.
The mirror body is made of aluminum die-casting material.
The shell is made of thermoplastic materials with better elasticity to achieve shock resistance and a firm and comfortable grip.
The rotary rubber eye cup with multi-card slot adjustment makes it easier for the eyes to be positioned at a comfortable eye point distance.
The waterproof structure is equivalent to the JIS level 6 standard and can be used in severe weather conditions.
The nitrogen-filled design can prevent the surface of the internal lens from fogging due to a sudden change in temperature.
The retractable eyepiece can be converted between the use position and the storage position.
Combined with optional TP-3 tripod adapter, it can be mounted on tripod.

Pentax SD 7 × 42 ED and SD 10 × 42 ED also use enhanced ultra-low dispersion (ED) lenses to achieve color difference compensation. The two telescopes integrate large objective lenses with a diameter of 42 mm, which claim to provide clear, high-contrast, high-standard images even in adverse lighting conditions (such as dusk).
Main features:
Consistent with the high-end Z-series models of Pentax, the latest dielectric high-reflection multilayer prism coating technology is applied.
A complete multiple coating process is applied to the surface of all lenses, and a special coating is used to optimize the light transmittance.
Equipped with a large objective lens up to 42 mm in diameter, it can provide a bright and clear view even in adverse light conditions, such as dusk.
The 6 mm exit pupil distance of Pentax SD 7 × 42 ED is suitable for astronomical observation.
The first of the Pentax S series uses the latest model of ultra-low dispersion (ED) optical lenses to compensate for color aberration.
The waterproof structure is equivalent to the JIS level 6 waterproof design standard and can be immersed to a depth of one meter under water.
The nitrogen-filled design can prevent the surface of the internal lens from fogging due to a sudden change in temperature.
The mirror body is made of aluminum die-casting material.
The shell is made of thermoplastic materials with better elasticity to achieve shock resistance and a firm and comfortable grip.
The rotary rubber eye cup with multi-card slot adjustment makes it easier for the eyes to be positioned at a comfortable eye point distance.
The objective lens and eyepiece also add a protective coating to erase traces such as fingerprints.
Easy-to-operate diopter adjustment mechanism with anti-slip ring regulator.
The retractable eyepiece can be converted between the use position and the storage position.
Combined with optional TP-3 tripod adapter, it can be mounted on tripod.
