Questions / Awnsers :
What is eye relief ?
The ocular lens is the one through which the user sees the image in the binoculars. Eye relief is the distance from the ocular lens to the user’s eye. The distance must be correct, in order to see a complete, clear and sharp image. If you wear glasses, you should choose a type of binoculars with eyepieces that can be pushed or folded in, because glasses offset the distance of the eye to the lens. Eterna™ Compact featuring fold-out/fold-in eyepieces.
How much magnification do I need ?
If the binoculars are going to be hand held and also used on moving platforms (eg at sea) we recommend 7x or 8x magnification. The characteristics of 8x25 (Eterna™ Compact) are an excellent choice. For outdoor use ashore it may be advantageous to choose more powerful magnification, depending on what you need them for.
What do the numbers mean ?
For example 8x25: “8x” means that the object in view appears 8 times larger than when visualised with the naked eye. “25” is the size or diameter of the front (object) lens expressed in millimetres. A larger diameter lets in more light and makes the binoculars better in poor light conditions.
Different glass qualities ?
There are two types of glass quality: Bak-4 and Bk-7. Bak-4 is extremely clean and transparent and is reportedly the best binocular grade glass on the market. Bak-4 quality is achieved through a complicated and time consuming manufacturing process. Bk-7 is the standard quality for glass in binoculars. It is less expensive to manufacture and therefore more popular for simple binoculars.
