Product care
Never point them at the sun. Clean the lenses with a proper cloth and a blower rather than a sleeve. Set the dioptre once for your eyes and leave it; re-check it if someone else borrows them. IPX6 covers rain. Dry them before they go back in a case. Use the neck strap - a dropped pair of porro prism binoculars usually comes back misaligned.
Full details

Pull distant detail right in with these Fellmont 20x50 Binoculars. Twenty times magnification paired with large 50mm objective lenses gathers plenty of light and delivers a bright, detailed image of birds, deer, boats, hills, stage acts and the far side of a stadium. They are a big step up from pocket binoculars when reach really matters.

BAK4 porro prisms and fully multi-coated optics keep the view sharp and high in contrast, with a field of view of 56m at 1000m so you can still find and track your subject. The central focus wheel plus a dioptre adjustment lets you balance the view for each eye, which makes long sessions far more comfortable. The 50mm lenses really come into their own at dusk and dawn, when smaller binoculars start to struggle and the view goes dim just as wildlife becomes most active.

A smartphone adapter is included, so you can clamp your phone to the eyepiece and record or photograph what you are watching to share later. The textured, rubber-armoured body grips well in cold or wet hands, and the IPX6 rating copes with rain. At 20x, a tripod helps steady the view for long watches.

Reach

A long step up from pocket pairs.

Twenty times magnification is a lot of binocular. Paired with **50mm objectives** gathering the light to support it, you get a **bright, detailed image** of birds, deer, boats, hills and the far side of a stadium — the kind of detail a compact simply cannot resolve at that distance.

  • **20x magnification**, 50mm objectives
  • **Birds, deer, boats, hills, stage acts, stadiums**
  • **BAK4 porro prisms**, fully multi-coated

Low light

50mm earns its keep at dusk.

The hour either side of sunrise and sunset is when wildlife is most active and when small binoculars **go dim and grey**. A **50mm objective** gathers considerably more light, which is why the view holds up when it matters. **Fully multi-coated** optics preserve that light through the glass instead of losing it to reflections.

  • **50mm objectives** for dawn and dusk
  • **Fully multi-coated** optics preserve brightness
  • **High contrast** in woodland shade

Using them

Set them to your eyes, then steady them.

**Central focus plus a dioptre adjustment** lets you balance the view for each eye separately, which is what makes a long session comfortable rather than tiring. The **textured rubber armour** grips in cold or wet hands and **IPX6** copes with rain. At 20x, **a tripod is worth having** for anything longer than a quick look.

  • **Dioptre adjustment** - balance each eye once, then forget it
  • **Rubber armour** and IPX6 weather resistance
  • **Smartphone adapter included** for photos and video

    It's beyond expectations.
    Now, surrounded by mountains and forests, it has become a park.
    I think the fun of experiencing nature will double when I go for a walk.
    It does have a bit of weight to it, but you get used to it quickly.

Frequently Asked Questions

Is 20x too much to hold steady?
It is at the limit. You can use them handheld for short looks, especially braced against a fence or a tree, but for a long watch the shake becomes tiring and you will see less detail than the optics can deliver. A tripod transforms them, and most people who use 20x binoculars seriously end up with one.
What does the dioptre adjustment do?
Almost nobody has two identical eyes. The dioptre lets you focus one barrel independently so both eyes see sharply at the same time. Set it once - focus the left eye with the main wheel, then the right with the dioptre - and you will not need to touch it again.
How good is the phone adapter?
It clamps your phone over one eyepiece so you can record or photograph what you are watching. Expect to spend a few minutes getting the alignment right the first time, and expect any shake to show badly at 20x. On a tripod it works well.
Will they fit in a bag?
These are full-size porro prism binoculars, so they are considerably bulkier than a folding compact. They come with a strap and will live round your neck or in a daypack rather than a jacket pocket. If pocketability matters more than reach, buy the compacts instead.
Are they any good for astronomy?
Surprisingly useful for the moon, bright planets and star fields, and 20x50 is a reasonable spec for it. You will want them on a tripod - holding 20x steady while looking upwards is close to impossible.
Are they waterproof?
IPX6, which covers heavy rain from any direction. They are not rated for submersion and are not nitrogen filled, so a sudden temperature change can fog the internal surfaces. Let them acclimatise rather than taking them straight from a warm car into the cold.
