The thing that makes me happiest about this scope is the fact that I can used my high end Meade Superwide and Ultrawide eyepieces with it. I popped in an 8.8mm Meade Ultra Wide and was blown away with the brightness and clarity. The 15mm Superwide was even better...

Great product, Warranty Service stinks!


from Cut Bank, MT  -  Professional Guide

Paired with one of Pentax's XW fixed magnification eye pieces (e.g., XW14), there's no question that this scope offers one of the finest viewing experiences for the price. The sharpness, field of view, colour rendition, flatness of field, and enough eye relief to suit eyeglass users (at least with the XW14 eyepiece) rivals the performance of some of the best scopes on the market. I was a happy owner for five years before I finally ponied up for a Kowa TSN-883, the first scope I encountered in some time that clearly outclassed the Pentax (but at three times the going price). On this count, you will not be disappointed! But something happened. Ricoh Imaging bought up Pentax. The famous lifetime warranty that Pentax sporting optics were known for was replaced quietly by something much more limited. Ricoh is neither timely nor generous in performing repairs. In the old days, if you brought back the pieces, Pentax would have probably sent you a new scope in under two weeks. Today, they'll shoddily mend those pieces after making you wait for over a month (more than six weeks in some cases), and the company is apparently so out of touch with itself that it has no idea when or even *where* repairs are being performed. A colleague of mine who dealt with them just recently had his scope bounced across the country to no fewer than three USA "repair centers" before they finally sent his scope back to him with the most modest of repairs. The old warranty made this scope a great value without peer. Ricoh should reconsider this matter. So while I continue to be a fan of this scope, I absolutely despise Pentax's new owner, Ricoh Imaging, which has a long record of dishonorable conduct in supporting its other imaging products, and as things now stand, I can no longer recommend Pentax sporting optics to without reservations. The Pentax name and technology has clearly been bought up by pirates. Buyer Beware!


I would buy this product again

Best high-end scope value.


from Salt Lake City, UT  -  Casual/ Recreational

Great for birding and big game scouting. This scope is in the same league as the $2,000+ scopes, i.e. Swaro, Howa, Leica, etc.


I highly recomend this spotting scope


from battle mountain, nv  -  Casual/ Recreational

i use this scope for spotting deer and elk, and whatever else i want to look at, even used it to check out the moon once. darn good choice here, and the price was awesome too, compaired to my buddies high dollar name brand spotting scopes.


Impressed so far, a good value.


from Columbus, OH  -  Casual/ Recreational

I'll qualify my comments by saying that I haven't had an opportunity to use the scope at a distance beyond 100 yds. yet but so far I'm very pleased with it. Image quality, features and design are comparable to high end spotting scopes. The scope takes standard U.S. astronomical eyepieces which helps it to get the best out of the 80mm low dispersion objective lens.

Good choice for rifle spotting scope


from Detroit, Michigan  -  Casual/ Recreational

I am a Highpower Rifle Shooter, which means I shoot a service rifle (AR-15) chambered in .223 at 200, 300 and 600 yard matches. I use this scope nearly every week on the practice range to spot holes in targets at 200 yards for myself and others. I spent an enormous amount of time reading other reviews, comparisons, etc, etc, etc, before buying this relatively expensive piece of equipment, but my evaluation criteria is very simple: can you or can you not spot a 1/4" (made by a .223 bullet) hole in the black at 200 yards, in the shade, or worse case, on an overcast winter day. With this scope, yes, every time. Birders have done a great job testing spotting scopes and carefully analyzing the results - but they're interested in color rendition, edge distortion, and other artistic criteria, which is great, but not useful to me. I just want to see 1/4" holes in the black, and you need a very good scope to do this. The Pentax has the right magnification, excellent resolution, and superior light sensitivity to make this possible. I have to wear prescription shooting glasses, which are bigger and further away from my eye than regular eyeglasses, so eye relief is a major feature for me. The Pentax has published eye relief for the SMC 21-63mm eyepiece, which comes with the PF-80 in the kit, of 18 to 22mm, and it turns out to be satisfactory for my use (by the way, don't bet your life on the published eye relief, you've got to look for yourself, if you wear glasses). I actually bought a different scope last year (was $675 with a great reputation), but I opened it up, put on my shooting glasses, looked through it, not good enough, sent it back, all within about 10 minutes of opening the box. Eye relief was clearly, definitely, unsatisfactory. I didn't know anyone with that scope and I hadn't looked through one before buying it - big mistake. With the Pentax, I definitely have to get right up on the eyepiece if I want to see the entire field of view while wearing my glasses (I don't need the entire field through, just the middle half or so), but again, the eye relief on the Pentax is good enough, and I'm yet to look through any other scope that has what I'd call "generous" eye relief - at least with the same magnification eyepiece. I have two other scopes, a well-regarded Chinese brand 20-60x80 that cost about $300, and an excellent American brand 12-40x60. The American scope is awesome, love it, but it doesn't have the magnification or objective size to really do what I need it to do. The $300 scope is unsatisfactory. Now that I've gotten used to the Pentax, I can't actually believe how poor the $300 scope is - this comment included for those of you wondering how much they have to spend. With the $300 scope you can see the holes in ideal lighting (sun shining on the target), but you cannot see them when the target is shaded or it's overcast. Overall, resolution, light gathering and field of view are very poor compared to the Pentax in field conditions, although I think it's a pretty decent scope for its price. I've looked through a lot of other people's scopes at the range as well. Many in my sport use the discontinued Kowa TSN-80, which has normal, not ED glass. This is a good scope, but the Pentax has ED glass, and I've spent lots of time looking through both in comparison, and I prefer the Pentax. To get a scope on a par with the Pentax, you are into high end choices with ED glass from Swaro, Kowa, Leica, Zeiss, and Nikon, at least these are the scopes I considered, and I had a chance to look through each of them (except the Kowa ED). Among these, the Pentax is by far the least expensive. Any of these would be fantastic to own, but they are 1.5 to 3+ times as expensive, and I really don't think I would be any more satisfied with their performance because the Pentax is outstanding. I use this scope OFTEN. Like every weekend, so I've had a chance to USE it in all kinds of different light conditions, and I know for sure now that it delivers. I highly recommend it. One more thing regarding testing. It's great to look through someone else's scope while they tell you how fantastic it is. This topic is so subjective, but in my case (1/4" holes at 200 in the shade - yes or no) the criteria is objective. I want to point out that looking out someone's window on a sunny day isn't useful. You have to use the scope, under different conditions, just as you intend to use it, to know if it is satisfactory. Just my additional 2 cents.


I Own This; Love it


from monterey, ca  -  Avid Adventurer

This is the highest quality scope you can get for an affordable price. It is a terrific scope in every way. One thing: if you are going mate it with a DSLR for photography, make sure, if you don't have a pentax camera, that you can find a quality adapter that works with your brand of camera before you buy the scope.


Extremely satisfied with this Pentax.


from Cantley, Quebec, Canada  -  Birder

Very happy with this purchase, I use it for digiscoping and birding. Very clear and crisp view and very illuminated. Used it with a DC Casio P600 up to today and are now using a Pentax K100D for digiscoping. They complement themselves very well. [...]


Exellent with 1 caution


from Seattle

I've set this scope up side by side with may scopes costing $500+ more and my scope has shown very well. The front 80mm lens lets in light enough to see when 65's have folded up for the night. The original lens can be removed and specialty lenses (higher power) can be substituted. I've had good success just holding my digital camera against the lens photographing falcon nests. Something like this is essential for wolf and bear observation in yellowstone or alaska. I'd recommend the larger Pentax to those who can afford it and the slanted version for those who want to also use it for astronomy uses.
