Product description

Built for long views and wet days

Twelve times magnification is for distance: seals hauled out on a sandbank, a buzzard circling over the far side of a valley, ships on the horizon. The 50 mm objective lenses give an exit pupil of 4.2 mm, the same as a 10x42, so the extra power does not come at the cost of a dimmer view.

The binoculars carry an IPX7 rating. Under the IEC 60529 standard that means they have been tested for temporary immersion in water at a depth of 1 metre for 30 minutes. That makes heavy rain, spray and a drop into a puddle a non-event. It does not make them suitable for use under water.

Optics and fit

The roof prisms are made from BaK-4 glass and the lenses are fully multi-coated, according to the supplier. BaK-4 has a higher refractive index than the cheaper BK-7, which helps keep the edges of the exit pupil round and bright.

Eye relief is 16 mm, and the twist-up eyecups let you set the right distance with or without glasses. The hinge adjusts from 61 to 74 mm between the eyepieces, and the right eyepiece has a dioptre adjustment of plus or minus 3 to balance the focus between your eyes. The close focus of 2.5 m means you can also look at a butterfly on a bramble or a bird on the feeder.

Steadying 12x

At 12x every movement of your hands shows. For a quick look, tuck your elbows into your chest or rest the binoculars on a wall or a fence post. For longer sessions, for example scanning an estuary or looking at the Moon, screw a binocular tripod adapter into the thread between the objective lenses and fit it to a tripod. The adapter is not included.

The binoculars weigh 1,046 g according to the supplier, more than a typical 8x42, so use the supplied wide neck strap. Read Best binocular magnification for bird watching to decide whether 12x suits the way you watch.

Questions about this product

What does IPX7 mean for binoculars?

IPX7 is a rating under the IEC 60529 standard for temporary immersion in water at a depth of 1 metre for 30 minutes. Rain, spray and a short dunk are fine. The binoculars are not made for use under water.

Are 12x50 binoculars too heavy to hold steady?

They can be held by hand for short looks, especially if you brace your elbows. For long sessions a tripod with a binocular adapter gives a much calmer view. The adapter thread sits between the objective lenses; the adapter itself is not included.

Can I use these binoculars for stargazing?

Yes. The 50 mm lenses gather plenty of light for the Moon, bright star clusters and Jupiter. On a tripod the 12x magnification shows more than a 10x50 held by hand. See our guide Binoculars for stargazing.

Can I use them with glasses?

Yes. The eye relief is 16 mm and the eyecups twist down, so your glasses can sit close to the eyepieces.
