Delta Optical Entry 7x50 Binoculars
The Delta Optical Entry 7x50 binoculars are designed for people who want reliable, quality optics without overspending. The combination of 7x magnification and a 50 mm objective lens delivers a bright, sharp image even in poor light - whether you are watching the dawn break in the mountains or observing birds at the forest edge after sunset. A field of view of 122 m at 1,000 m (7°) makes it easy to follow moving subjects without constantly refocusing. The relative brightness value of 50.4 confirms that these binoculars are well suited to low-light observation.
Simple, responsive controls
The central focusing wheel makes operation intuitive and quick. When something moves in the landscape, you can react immediately without fumbling. The dioptre correction range of +/-4 dioptres lets you fine-tune the image to suit your eyesight - even if you normally wear glasses or contact lenses. A minimum focusing distance of 8 m is useful when you need to observe nearby subjects. The retractable rubber eyecups provide a comfortable fit whether you are wearing glasses or not.
Quality optics from glass to coating
The optical system uses BaK4 prisms, which prevent edge darkening and ensure even brightness across the entire field of view. The lenses carry an MC anti-reflection coating that reduces reflections and increases light transmission. The result is a natural, well-contrasted image with accurate colours. The aluminium body is wrapped in black rubber that absorbs knocks and provides a firm grip even in wet conditions. The waterproof construction protects the optics during light rain or in humid environments.
Practical size and weight
Despite the 50 mm objective lens, the Entry 7x50 weighs only 844 g - a very favourable result for this class of binoculars. The dimensions of 170 x 200 x 68 mm match a standard size that fits easily into a rucksack. Lens caps, a carrying strap and a hard case for safe transport are all included. The Delta Optical Entry 7x50 binoculars are a practical companion for day trips, expeditions and everyday nature observation.
