The Pentax SP 20x60’s are a pair of high-quality, waterproof, nitrogen-filled binoculars suited to long-range or astronomy observations. The large 60mm objective lenses are housed inside a rugged, rubber armoured body and also come with the newly developed coatings to maximise light transmission and ensure a bright, clear viewing experience.
Pentax SP 20x60 WP Observation Binoculars:
- New fully multi-coated optics
- Phase correction
- Protective lens coating
- Nitrogen purged
- Unique hydrophobic coating
- Aspherical lens elements
- Magnesium alloy construction
New Fully-multi-coated optics:
Fully multi-coated lenses serve the essential purpose of maximizing the amount of light passing through a lens, thereby prevent flare and ghosting from interfering with your view. Pentax applies multiple layers of coatings to every surface of every element and prism in the full Sport Optics line-up. These fully-multi-coated optics assure the maximum light transmission resulting in a clear, crisp view of the world.
Protective Lens Coating:
All optical surfaces are delicate and must be handled with care to prevent scratching. To add to the durability of the Z- and S-series Water Proof binoculars, Pentax has added a protective, Nano technology coating that helps deflect water, oil, dust and dirt. This allows Pentax binoculars to withstand the harshest viewing conditions.
Due to its outstanding refractive index, the BaK4 glass prism found in all Pentax Sport Optics is highly acclaimed for its perfectly round exit pupil and clear, unvignetted image.
The complex optical design of roof prism binoculars provide durable, compact, yet lightweight design but require a higher level of optical perfection. A phase-correction coating is applied in the full range of roof prism binoculars to maximize image viewing quality.
Pentax waterproof products are fully sealed and purged with laboratory grade nitrogen to provide a fog proof view in the harshest weather conditions. With a JIS Class 6 rating, Pentax waterproof binoculars can even be submerged in up to 3 feet of water.
Unique Hydrophobic Coating:
Water droplets on a lens have a negative influence on the ability of light to enter the objective lens. By using a unique water repellent coating on all outer lenses we make water drops “bead” into small, deformed droplets. The deformed droplets cause less distortion and “slide” more easily off the lens. Your binocular remains fully functional even in rain, snow, fog or condensing breath.
Aspherical lens elements:
Edge-to-edge sharpness is a vital element to comfortable viewing. To achieve this, we utilise aspherical lens elements in our eyepieces. This is a specially shaped lens design that reduces aberration to a minimum.
Nitrogen is a chemical element and a colourless, odourless and tasteless gas. It contains very little humidity and is therefore used to “purge” binoculars and spotting scopes of the high humidity air that is part of our environment. Due to the low humidity factor, nitrogen prevents condensation from forming on the internal lenses of optical instruments during phases of rapid temperature change. Furthermore, because nitrogen is purged into the optical instrument at slightly above atmospheric pressure, dust and other miniscule particles are prevented from entering the housing.
Long eye relief design:
The long eye relief offered in all Pentax Sport Optics allows the viewer to see the entire field of view clearly and effortlessly. This is especially beneficial to eyeglass wearers, and allows viewing for extended periods of time without added eye strain.
Superb impact resistance:
The body is made from magnesium, which adds toughness while keeping the binoculars light. In addition, the exterior rubber coating provides the binoculars with superb resistance to shocks and impacts.
Helicoid three-stop eyepiece rings that permit fine adjustment for maximum viewing comfort.

Applicants must be:
- Aged 18 years or older from the application date
- In permanent UK residence for a minimum of three years
- Fulfil at least one of the following employment criteria:
- In regular, permanent employment.
- Retired from regular employment - With a minimum age of 50.
- Not working through disability.
Note: All applicants will be subject to a credit reference check by the lender.
The approval of your application depends on your financial circumstances and borrowing history. Warehouse Express Ltd trading as Wex Photo Video act as credit broker and not the lender. Barclays Partner Finance act as the lender.
Can I repay early? If so how?
No repayments are scheduled in the initial six-month deferral period. However, it is possible to pay off the loan, either by way of a lump sum or in smaller amounts. If the loan is fully repaid within the six-month deferral period, then no interest is payable, but a £29.00 early-settlement will be incurred. Such repayments may be made to Barclays Partner Finance by cheque, debit card or standing order. Unfortunately it is not possible to set up a direct debit within the deferral period. Further information on how to make such repayments will be set out in the loan agreement pack provided by Barclays Partner Finance.
What happens if I don't repay within the first six months (deferral period)?
Following the six month deferral period, Barclays Partner Finance will initiate a monthly direct debit payment for the remaining duration of the loan. Interest will be charged at a rate of 19.9% APR on outstanding balances (backdated to the first date of the loan). Late payment penalties and early repayment charges will apply from this point. Barclays Partner Finance will send a reminder letter approximately one month before the six month deferral period is due to elapse. Note: If you chose to spread the cost and pay monthly, interest is charged from the start of the loan, not from the start of the repayment period.
What will I receive from the finance provider (lender)?
Barclays Partner Finance will send a loan agreement pack approximately four weeks after delivery of the goods, confirming that the account has been activated and, from this point, it is possible to make repayments against the loan.
