Nikon ACTION EX 7x50CF

The Nikon ACTION EX 7x50 CF combines steady 7x magnification with large 50 mm objective lenses. This configuration provides a bright, natural-looking image and makes the binocular suitable for daytime observation, cloudy weather, twilight conditions and wide-field views of the night sky. Its 6.4° real angular field of view corresponds to 112 metres at a distance of 1,000 metres. The central focusing mechanism allows quick adjustment, while the aspherical eyepiece lens helps reduce image distortion. Multilayer-coated optical elements improve light transmission and image clarity. The nitrogen-filled body helps prevent internal fogging during sudden temperature changes. The binocular is waterproof to a depth of 1 metre for 5 minutes, while the rubber-armoured exterior provides a secure grip and additional protection against everyday impacts.

Comparison with alternatives

 

Compared with the Nikon ACTION EX 7x35 CF, the 7x50 model provides the same steady 7x magnification but features larger 50 mm objective lenses and a 7.1 mm exit pupil. It is therefore better suited to lower-light observation, although it is larger, heavier and has a narrower field of view.

Compared with the Nikon ACTION EX 10x50 CF, the 7x50 model offers less magnification but is easier to hold steady. The 10x50 model reveals more detail in distant subjects, while the 7x50 provides a larger exit pupil and relaxed wide-area viewing.
