Delta Optical Forest II 10x50 Binoculars (DO-1301)

For those waiting for upgraded binoculars in the Delta Optical Forest II series, there is good news: three new models with large 50 mm objective lenses are now available—8.5x50, 10x50, and 12x50.

Like the rest of the Forest II line, these binoculars use roof prisms, making them compact and lightweight. Designed with both aesthetics and quality in mind, they are built from durable, high-grade materials.

The previous Forest II models, especially the 8x42 and 10x42, were a great success.

The Forest II 10x50 is a binocular with classic specifications, popular among nature observers. Its versatile design allows comfortable use during both day and night. It strikes an excellent balance between high magnification and a wide field of view, while still maintaining impressive image brightness.

The entire Forest II series features an optical system made up of 8 elements in 6 groups, using high-quality phase-corrected BaK4 roof prisms with silver-coated reflective surfaces for sharp, bright images. All lens surfaces are coated with advanced FMC (Fully Multi-Coated) anti-reflective coatings, resulting in high light transmission and natural color rendering. The well-blackened interiors prevent unwanted reflections and ghosting.

Each Forest II binocular includes a smooth central focus wheel and individual diopter adjustment in the right eyepiece. Twist-up rubber eyecups can be extended for comfortable positioning. The Forest II binoculars are ready for tough weather conditions: their sealed body ensures reliable use in damp environments and even in the rain. They can be submerged for up to 5 minutes to a depth of 1 meter. Nitrogen filling prevents the internal optics from fogging.

A major advantage of the new models is their compact size and low weight. All Forest II 50 mm binoculars have identical dimensions—165x133x60 mm—and weigh less than 850 g. They are the perfect compromise between smaller 42 mm models and much heavier 56-63 mm binoculars. Thanks to the versatile 50 mm objective size, the new Forest II models offer different magnification options, so you can select the one best suited to your needs.
