Delta Optical Chase 10x50 ED

• ED objective lenses: Extra-low dispersion glass helps reduce color fringing, so fine detail stays cleaner against high-contrast backgrounds such as bright sky, water or snow.
• 10x50 configuration: The combination of 10x magnification and a 50 mm objective gives useful reach for open-country observation while maintaining a bright 5.00 mm exit pupil for comfortable daytime and dusk use.
• Roof prism design: The Schmidt/Pechan prism system keeps the binocular slim and easy to carry, making it more practical for hunting, travel and general field observation than bulkier porro designs.
• Fully multicoated optics: Full multi-coating improves light transmission and contrast, which helps the image look clearer and less washed out in difficult lighting.
• Waterproof, nitrogen-filled housing: A sealed body with nitrogen filling resists internal fogging and supports reliable use in rain, cold mornings and changing outdoor temperatures.

About the Delta Optical Chase Series

Delta Optical Chase is a binocular series built around practical field use, with models in 8x42, 10x42, 10x50 and 12x50 ED configurations. The range is intended for nature observation, tourism and daytime hunting, covering users who want a compact roof-prism format but still expect strong optical performance. Across the series, Delta Optical uses ED glass in the objective lenses to limit chromatic aberration, which helps preserve cleaner edges and more natural color in high-contrast scenes.

Every model in the series uses a roof-prism design with central focusing, giving the Chase line a straightforward, field-friendly layout that is easy to handle with one hand while tracking moving subjects. The series also uses a waterproof construction rated IPX7, which suits outdoor use in wet weather and adds reassurance for travel and hunting optics that may be exposed to rough conditions. In Delta Optical’s lineup, the Chase family sits as a versatile all-round option for users who want modern binocular ergonomics, ED optics and dependable weather resistance without moving into a more specialized format.

About the Delta Optical Chase 10x50 ED

Delta Optical Chase 10x50 ED is the larger, brighter all-round model in the Chase family for users who want more low-light capability than a 42 mm binocular can usually provide. Its 10x magnification offers enough reach for scanning fields, shorelines and distant tree lines, while the 50 mm objective lenses help maintain image brightness when light begins to fade. That makes this configuration especially well suited to hunting, wildlife observation and general outdoor use where detail at distance matters but the binocular still needs to remain portable.

The use of ED glass is particularly useful in a 10x binocular, where chromatic aberration becomes easier to notice around branches, birds and other high-contrast subjects. By reducing that color fringing, the image appears cleaner and more precise, which makes prolonged observation less tiring. The fully multicoated optical system further supports contrast and image clarity, while the 109.20 m/1000m field of view remains wide enough for locating subjects without the tunnel-like feel that stronger magnification can sometimes bring.

Mechanically, the binocular uses a central focusing system and a central diopter adjustment, keeping operation simple and familiar in the field. The roof-type Schmidt/Pechan prisms allow a more streamlined body than traditional porro binoculars, and the single-hinge construction gives a secure grip. With a nitrogen-filled, waterproof and fogproof housing, plus a weight of 890.00 g, this model balances durability and steadiness for users who prioritize a bright 10x50 hunting binocular over the lightest possible carry weight.

About Delta Optical

Delta Optical traces its beginnings to 1989, when it opened an optics shop for enthusiasts. The company is based in Nowe Osiny, near Mińsk Mazowiecki, and it serves users across astronomy, biology, hunting and shooting. That broad involvement in observation and sporting optics helps explain why its catalog covers both field binoculars and more specialized sighting equipment.

Within shooting optics, Delta Optical’s better-known lines include Titanium, Stryker and Hornet. The company describes Stryker as a precision scope range for medium- and long-range target shooting, while its sporting optics use proprietary reticles and anti-reflective coatings. This background in both observation optics and shooting equipment gives the brand a practical, application-focused reputation, with products designed around clear optical performance, durable construction and straightforward field use.
