Description
10x42 roof prism binocular with UHD glass and edge-to-edge sharpness, for hunting, birdwatching and general nature observation.
The Cronus G2 UHD 10x42 is the compact configuration in Athlon's flagship binocular line. UHD extra-low dispersion glass and the E2ES edge-to-edge field-flattening system keep the image sharp and free of chromatic fringing right out to the edge of the field of view, rather than only in the centre as with simpler optical designs.
A magnesium chassis keeps weight down without giving up the rigidity a full-size 42 mm binocular needs, and the 10x magnification with a 6.5° angular field suits general field use from woodland hunting to long-session birdwatching.
Key features
- UHD extra-low dispersion glass — reduces chromatic fringing for a cleaner, higher-contrast image.
- E2ES edge-to-edge sharpness — the field-flattening system removes distortion at the outer edge of the field of view.
- ESP dielectric prism coating — reflects over 99% of the light through the prism assembly for accurate colour reproduction.
- Phase corrected BaK4 prisms — maintains contrast and resolution across the field.
- Magnesium chassis — reduces weight while keeping the rigidity of a metal body.
- Locking diopter — holds the individual eye adjustment in place once set.
- Twist-up eyecups with long eye relief — 19.3 mm eye relief, usable with or without spectacles.
- Argon purged and sealed — waterproof, with XPL protective coating on the exterior lenses.
Typical applications
- Hunting — glassing and game spotting
- Bird watching and general nature observation
- All-day carry where weight matters
