Athlon Optics Cronus G2 UHD 10x42 Binoculars

Gridding a far hillside for a bedded buck means studying the edges of the view as closely as its center. The Athlon Cronus G2 UHD 10x42 is built for serious glassing, with the E2ES field flattening system, which removes distortion at the outermost edge of the field of view, over UHD extra-low dispersion glass, a locking diopter and 19.3 mm of eye relief.

Key Features

• E2ES field flattener. It gives a sharper, clearer image from one edge of the lens to the other. Among Athlon's binoculars, only the Cronus G2 UHD line has E2ES.
• Glass and prisms. UHD extra-low dispersion glass, designed to leave little or no color fringing, and an ESP dielectric coating on phase-corrected BAK4 prisms that reflects 99% of the light through the prism assembly, with advanced fully multi-coated lenses and an XPL protective coating on the outer lenses.
• Locking diopter. The locking diopter control sits directly below the center focus knob.
• Eye relief and close focus. 19.3 mm of eye relief, with twist-up eyecups that go fully down for eyeglasses and have an intermediate stop, and focus down to 6.6 ft.
• Built for weather. The magnesium chassis keeps weight down while staying rugged enough for the scrapes and bumps of constant use. The binocular is waterproof and fogproof, argon purged rather than nitrogen filled.

Ideal For

• Hunters, birders and nature watchers, the three uses it is designed for.
• Which Athlon 10x42? The Midas G2 UHD 10x42 weighs 23.3 oz against 27.8, with a 341 ft field against 338, and costs less. The Cronus answers with E2ES, the locking diopter, 19.3 mm of eye relief against 15.2 and focus to 6.6 ft against 8.2. The Argos G2 UHD 10x42, in an open-bridge style, gives a 319 ft field, 16.1 mm of eye relief and 13 ft close focus at 25.5 oz, and the Argos G2 HD 10x42 has the same figures without UHD glass. Both cost less.
• More reach. The Cronus G2 UHD 15x56 brings E2ES to 15x with Abbe prisms, at 45.2 oz.

Accessories & Compatibility

• Tripod. A ¼-20 tripod adapter socket under the logo plate on the hinge takes the Athlon Binocular Tripod Adapter, which mounts the binocular on a regular camera tripod.
