20x50 Magnification & 50mm Objective

These binoculars deliver 20x magnification through a 50mm objective lens. The 26mm large eyepiece produces larger images with clearer details. Designed for adults and children, they suit outdoor activities including bird watching, hunting, travel, stargazing, concerts and sightseeing.

Upgrading from Lower Power

Moving to 20x magnification and a 50mm objective is worthwhile when you need greater reach and more light gathering for distant or low-light subjects. Smaller apertures and lower powers limit detail resolution and brightness in dim conditions. This combination improves performance for astronomical observation and twilight use.

Limits of High Magnification Hand-Held Optics

At 20x magnification, hand tremors become visible and image stability decreases without support. The narrow exit pupil reduces brightness in very low light despite the 50mm objective. A tripod or stable rest is often necessary for extended viewing at this power level.

Questions about this item

Does the 50 mm objective lens need a specific tripod adapter thread?

The binoculars have a standard tripod socket that accepts common 1/4-20 adapters, so no proprietary mount is required.

How do I set the 20x focus correctly for each eye?

Close the right eye and turn the centre wheel until the image is sharp, then close the left eye and rotate the right eyepiece dioptre ring until that eye is also sharp.

What care keeps the BAK-4 prism and FMC coating performing in damp conditions?

Wipe the lenses only with a microfibre cloth after each use, store the unit in its case with a silica packet, and avoid touching the coated glass surfaces.
