Excellent optics

I have an earlier version of these binos, not waterproof and made in China. They are optically excellent, nearly as good as my full size Nikon Monarch 5 glasses. If the clarity and resolution of this version is equivalent, they are a bargain. Construction and materials is good - mine look like new after nearly a decade of use. Where these compacts fall down is in low light, but that will be the case with any binos with smaller than 5mm exit pupil.

Recently purchased these binoculars for a trip to Costa Rica. Used them while hiking. These binoculars offer a very clear image with good low light detail. They seem constructed very well and are very durable. They are small enough to not weigh you down while hiking. A great balance between image quality and weight/size.Highly recommended !

Quick first impression
18 July 2017

I was looking for binoculars primarily for birding while kayaking and hiking. Compact, waterproof and inexpensive coupled with reasonable optics were all features that were important.Just finished a 4 day kayak trip. The binoculars really added to my enjoyment. The only quibbles I have is that once you attach the strap the binoculars don't fit back into the case with ease. It requires the fiddle factor which is annoying after a while. It would be great too, if the strap had a little padding, as it really rubs after wearing them around your neck while paddling. Easy to do a DIY fix, but even better if Pentax included it as a feature.Otherwise, I really liked them and think they are good value for the cost.

Seem pretty good, so far
31 August 2020

Only used them on one trip, to date, but I like them so far. As another reviewer mentioned, it's a bit fiddly to get them back in the case once the strap is attached, which is pretty dumb, but also not a huge distraction. I'm just hoping they'll last better than my Pentax AD binoculars, which suffered a rather catastrophic failure after less than a year of use. Keeping my fingers crossed . . .

Several bits failed
22 May 2019

I bought a pair of these 7 or 8 years ago. I used them a lot for kayaking and they worked very well. Unfortunately several parts failed, one of the objective covers came off and both strap attachments failed. Fairly good, for the price but I am now going back and going to spent the extra $50 for something that might last

The perfect travelling companion.
12 February 2020

I can see clearly now. I have a very good pair of 7 x 50 binoculars which I was taking on a cruise, but found them bulky to carry and pack. Plus they weighed 800grams. These new Pentax 8 x 25 with zoom only weigh 300 grams and are the perfect size to carry around, either hanging around one's neck on the strap or in a purse. They are supplied with a nice case which has belt loops also. Image is crystal clear, no hand shake is detectable, even on max zoom. I showed them to a friend while we were comparing binoculars and he asked if he could buy them off me. I guess that says it all.

Unique and perhaps necessary
18 March 2023

When on sale I buy these for gifts. The AD WP double hinge roof is a next solid choice and is my compact take always with better ER at 21. These however are a Time Capsule being reverse porro with what I find a Kool design, decent fov and unique push in/out right eye dopler adjustment. Waterproof too. To experience a compact Porro at this price is pretty amazing considering the inferior 100$ choices flooding amazon.com. Pentax Ricoh really do make incredible under 300 $ products. I've seen reviews of people preferring it to the Nikon reverse porro competition as well. The Pentax Ricoh Papilio 2 6.5x21 is also another example of what Pentax Ricoh can achieve and I think this is a great achiever as well.

I lost my work truck's Brookstone binoc's to a break in. My replacement binoc's became my Dad's old Minolta pocket 7x21's which I thought were pretty good... I wanted to give his back and not super knowledgeably on binoculars found these to consider at B&H as a replacement. I've bought from B&H before and know they sell quality items and know stuff. I'm use to twin tubes but these are quite comfortable to handle, focus, adjusting the diopter and have adjustable eyepiece rings, great if wearing safety glasses. But the important part is the view...Wow! The viewing difference between my old Brookstone's and Dad's Minolta's was like going from horse carriage to the automobile.

This Pentax pair to me is like your car now has air conditioning, power steering, power windows and all the nice things that make you smile. If you want a good solid workhorse pair of binocular that let you see things you should be seeing, you won't be disappointed, even in a surprisingly comfortable but odd appearance, but when look through them, you'll see why.

previous model but very similar - leaves you wanting more
21 May 2021

I got these as a general pair of binoculars. For camping, looking for portage markers, wildlife watching, bird watching, etc.The problem is that they just simply are strong enough. When others have higher end binoculars it really makes you realize how much you are missing.I did take them to South Africa and they held up. Which speaks to their durability
