RSPB Binoculars

About RSPB binoculars

The RSPB doesn't make binoculars itself. Its optics are designed with Viking Optical, which has supplied RSPB own-brand optics under an exclusive agreement for more than 20 years, and they're built around what birders and wildlife watchers actually need: a wide view for finding birds fast, close focus for butterflies and the feeder, and bodies that shrug off rain. The charity says every purchase from its own shop supports its nature conservation work.

The range runs from children's binoculars at under £35 to the flagship Sparrowhawk at around £850, so there's a pair of binoculars for every budget and level. What links them all:

• Roof prism designs that are slim, light and easy to seal
• Fully waterproof, nitrogen-filled bodies that won't mist up inside
• Twist-up eyecups (twist-down on some models) that work with or without spectacles
• A case, neck strap and lens caps in the box
• Lightweight bodies with good image quality for the price
• Warranties of 1 year (Skylark, Puffin Jr), 5 years (Avocet) or 10 years (HD and above)

The RSPB binocular range explained

Each model is named after a bird, and the price climbs with the glass and coatings inside, which is where most of the gain in clarity and image quality comes from. The RSPB's own buying guide splits binoculars into starter (£50 to £150), mid-level (£150 to £350) and advanced (£350 and up), and the range follows the same steps.

Starter: RSPB Skylark, Puffin and Puffin Jr

The Puffin Jr is an 8x21 pair for children aged 7 to 12, light enough for small hands but with the build quality of an adult pair, fold-down eyecups and a wide view that's easy to hold still. The full-size RSPB Puffin comes in 8x32, 8x42 and 10x42 for adults on a tight budget. The Skylark is the best-known entry-level binocular in the range: fully waterproof, nitrogen filled, with twist-up eyecups, a case and a neck strap, and sold in three sizes. The Skylark 8x42 earned a Which? Great Value endorsement and was named number 8 in the Which? Top 50 Products of the Year 2025, with testers saying it competes with pairs ten times the price.

Mid-level: RSPB Avocet and Harrier

The Avocet is the mid-level favourite: high quality binoculars for the money, with fully multi-coated lenses, a 3m close focus distance on the 8x32, a padded neck strap and a 5-year warranty. It comes in three full-size models plus 8x25 and 10x25 RSPB compact binoculars for a pocket. The Harrier steps up to dielectric, phase-coated prisms for a brighter, crisper view. The range also includes Avocet and HD monocular models and Harrier spotting scopes, which aren't on this page.

RSPB HD and HD compacts

The HD brings double ED lenses and phase-corrected prisms to a more affordable price, with a 2m close focus that suits garden birds and insects. The 8x42 has 20.3mm of eye relief, the most of any pair on this page. The 10x25 compact weighs only 300g, has a magnesium alloy body and is the pair the RSPB names as its favourite affordable compact.

RSPB Harrier X

The Harrier X adds ED lenses to the Harrier's dielectric prisms and wraps it in a magnesium alloy body with rubber armour and thumb-holds. The 8x32 weighs just 524g and gives a 145m field of view at 1,000m, so it's easy to carry all day and quick to get on a moving bird. The eyecups have three twist-down settings for fine adjustment.

RSPB Buzzard ED

The Buzzard adds field flattening lenses, which keep the image sharp closer to the edge, to ED lenses and dielectric, phase-coated prisms. The 8x42 has a wide 142m view at 1,000m and comes with a rainguard and tethered objective caps. Bird Watching magazine's review found it clean, bright and strong in low light, and measured close focus at around 1.3m, well inside the stated 2m.

RSPB HDX

The HDX is built for size and weight. At 660g to 680g it's one of the lightest 42mm roof prism designs available, and a small bridge lets you hold it in one hand. ED lenses and both phase and SHR (super high reflective) coatings give a bright, high-contrast image with excellent clarity.

RSPB Sparrowhawk ED: the flagship

The Sparrowhawk sits at the top of the range in 8.5x42 and 10x42. It combines ED lenses, dielectric-coated Schmidt-Pechan prisms and field flattening lenses in a 700g magnesium body. The unusual 8.5x magnification gives a little more reach than 8x while keeping a 140m view at 1,000m.

The whole RSPB range at a glance

Which RSPB binoculars should you buy?

• First pair on a budget: the Skylark 8x42, the Which? pick among entry level binoculars.
• Best value step up: the RSPB Avocet 8x42 for a 5-year warranty and better prisms, or the HD 8x42 for double ED glass.
• Spectacle wearers: the HD 8x42 (20.3mm eye relief) or the Harrier X 8x42 and Buzzard (18.4mm).
• Long walks and travel: the Harrier X 8x32 at 524g, or the 300g HD 10x25 compact.
• Estuaries, reservoirs and moorland: a 10x42 such as the Harrier X, HDX or Sparrowhawk.
• Dawn, dusk and woodland: an 8x42 for its 5.25mm exit pupil and wide view.
• The best the charity sells: the Sparrowhawk ED 8.5x42.

Before you buy, run through three quick checks:

1. Pick the magnification: 8x for woods, gardens and hides, 10x for open country.
2. Pick the lens: 42mm for brightness, 32mm or 25mm to save weight.
3. Check comfort: eye relief if you wear glasses, and a focus wheel you can reach easily.

8x or 10x magnification?

For most birdwatching, 8x magnification is the easier choice: the view is wider, brighter and steadier, so it's quicker to find a warbler in a hedge. 10x brings distant waders and raptors closer but shows more hand shake. If you mainly watch over open water, compare our 10x42 binoculars; for pairs above 10x, see 10x50 binoculars.

32mm or 42mm lens diameter?

The second number is the objective lens diameter in millimetres. A 42mm lens gathers more light, which helps in poor light, while a lightweight 32mm pair saves your neck on long walks. The Harrier X 8x32 is nearly 200g lighter than the 8x42. Browse our 8x32 binoculars for more light pairs, or compact binoculars for pocket sizes. The RSPB's binocular terms guide explains eye relief, exit pupil and the other specs.

How the RSPB compares with other brands

These ED pairs sit in the same price bands as several brands we stock:

• Hawke binoculars offer a no-fault lifetime warranty and ED lenses from under £350.
• Viking binoculars come from the same optics firm that supplies the charity.
• GPO binoculars and Kowa binoculars are worth a look if you're spending £500 or more.

The strengths of this range are a wide view, close focus and a 10-year warranty on every pair here, plus build quality that suits binoculars for bird watching in all weathers.

Setting up and caring for your RSPB binoculars

1. Set the hinge so you see one round image.
2. Close your right eye and focus with the centre focus wheel, then close your left eye and turn the dioptre on the right eyepiece until it's sharp.
3. Twist the eyecups up if you don't wear glasses, or leave them down if you do.
4. Brush off grit before wiping the lenses with a lens cloth.
5. Let a wet pair dry at room temperature with the caps off, then store it in its case.

Then take them out: the RSPB's nature reserve finder lists reserves with hides across the UK, and the Big Garden Birdwatch each January is a good first outing for a new pair.
