Pentax SD WP overview

  • 1Description

Pentax designed the 8x42 S-Series SD WP Binocular for a lifetime of rugged outdoor use in all weather and lighting conditions. The 42mm objectives are fully multicoated to reduce reflection and maximize light transmission through the entire optical path. Its roof prisms are phase-corrected to correct for chromatic aberrations ensuring bright and clear high-contrast images with true color rendition even in low-light. Its general purpose 8x magnification brings subjects close while maintaining a wide 60° angle of view to preserve situational awareness.

Complementing the optical performance are construction details made for the trail. The optical tubes are nitrogen-filled and O-ring sealed for fogproof performance and to make them submersible to as much as 3.3'. The binocular sports a generous 21mm eye relief and its twist-up eyecups ensure comfortable viewing with or without eye wear. Protective coatings on the exterior lens surfaces repel water, dirt, and oil to keep them clean for unobstructed viewing.

Pentax SD WP reviews

8x42 S-Series SD WP Binocular is rated 4.3 out of 5 by 3.
Rated 5 out of 5 by from Fantastic value, optics are far better the price suggests One of the best values in 8x42 roof prism binoculars, with optics that is far above the incredibly modest price. Very easy to handle, but the eye relief twist mechanism is mushy, and a little difficult to precisely set at a given position. I would have preferred a geared mechanism that provided like 3 or 4 crisp, clickable positions. But that's a nit - for the price, this is just amazing value. The eye relief is big enough that it should work for a lot of eyeglass wearers, but this is always a question of individual physiology. So I would highly recommend testing it to see how well it works for you ergonomically.

Rated 4 out of 5 by from Excellent optics, narrow field of view Very well made binocular with excellent optics in terms of color, contrast and corrections for aberrations. Price is very reasonable, compared to high end binoculars that cost double the money. Handling is excellent. Main problem is the narrow depth of field of only 331 feet at 1000 yards (110 m at 1000 m). That is 10-20% less than other similar binoculars. So this is not the best binocular if you're looking for a wide field of view. But if the narrower FoV works, then you're getting $2000 quality optics at half the money. The eye relief is large enough that it should work for people who wear eye glasses, but as an eye glass wearer, it was marginal for me. As always, you have to check the binocular to see if the eye relief can work for you. Overall, I am clicking the Yes, I would recommend choice below for the Bottom Line, but with the qualifier that this binocular has enough good things going for it that it deserves serious consideration, but it may not work for all.

Rated 4 out of 5 by from Excellent package overall This is my third pair of Pentax binocs, the other roof prism pair being a set of DCF-HS 10x36s. The out-of-plane chromatic aberrations are reasonably well controlled, about on par with the DCF set. These are very bright, on the verge of obnoxiously so during peak daylight, and once in focus, the sharpness is hard to beat. I get the sense the only imaging performance improvement you'd gain by going up in their range is better control of out-of-focus detail... I don't see any way you can appreciably improve on the sharpness of a pair of 8x binocs. Design issues are the only reasons I give these four stars. The location of the diopter correction, which is the other main improvement from moving either up or down in the range, is weird. I find that it's too easy to bump this protruding lever when stowing, which either then requires an adjustment or for me to flatten the hinge and reset to about where I think I should be. These are the only specs in the Pentax range that have this lever here, so maybe this issue only bothers me. The other is the ease with which the eye cups twist in and out... they could stand to be tighter. Construction otherwise is fantastic... very solid, well-placed hand grips, and I think once the focus knob breaks in a little, that'll feel fine too. Regardless, and especially if you're looking for a pair to keep ready somewhere, this is a good buy.
