Delta Optical Extreme 7x50 ED

The Delta Optical Extreme binoculars are an exceptional optical instrument, meticulously designed to deliver unparalleled performance. These binoculars combine top-notch optical properties with robust mechanics to offer an extraordinary viewing experience. The implementation of porro prisms, low-dispersion elements, and high-quality BaK-4 glass prisms showcases the commitment to excellence in their design.

One of the standout features of the Extreme binoculars is the utilization of ED lenses, which significantly reduce chromatic aberration in the image. The powerful prisms ensure that vignetting and image darkening at the periphery of the field of view are not a concern. Additionally, modern antireflection coatings (FMC) cover all optical elements, guaranteeing over 90% light transmission throughout the system. The result is a bright and remarkably lifelike picture with natural color rendition. Astigmatism, coma, and distortion are all expertly corrected, yielding a flawlessly flat image.

In summary, the Delta Optical Extreme binoculars offer an incredibly bright, sharp, and high-contrast image across the entire field of view—a testament to their exceptional performance.

The 7x50 model stands out as a wide-angle and exceptionally bright binocular. Its excellent resolution and image brightness make it ideal for hunting, enabling the user to discern intricate details of the game. These binoculars are also perfect for night-time observations in various applications. Built with durability in mind, they are well-suited for use on yachts, cutters, or ships, providing optimal magnification for observations on a swaying deck.

Astronomy enthusiasts will also find the Extreme 7x50 ED binoculars to be a fantastic option. They provide expansive views of vast sections of the night sky and are particularly suitable for observing the magnificent Milky Way. With a notably large depth of field, these binoculars often require little to no focus adjustment in many cases.

Crafted from robust metal and coated with a special rubber veneer, the bodies of all Extreme models ensure a secure grip and effective cushioning in case of accidental drops or impacts. The mechanical components of these devices are designed to operate within a wide temperature range, from -40 to 70 °C.

Another notable feature of the Extreme series is their full water resistance and internal fog protection. Filled with pure nitrogen, these binoculars can withstand even the most challenging weather conditions. The larger size of the Extreme binoculars allows for easy handling, even while wearing gloves in wintry conditions.

The Extreme binoculars feature an individual focusing system, allowing users to fine-tune the focus for each eye. The comfortable eyecups effectively block out external light and, combined with the ample eye relief, ensure a comfortable and immersive viewing experience.

Each set of Delta Optical Extreme binoculars includes a durable case, lens and eyepiece covers, as well as a convenient belt for easy transport.
