New! The Oberwerk Sport ED Series, with their ED (extra-low dispersion) objectives and wide 65° AFOV (apparent field of view), are the finest roof-prism binoculars we’ve ever offered. Because of the ED objectives, chromatic aberration, or false color, is completely eliminated from the view. Available in either 8×42 (8.1° FOV) or 10×42 (6.5° FOV), they’re the perfect choice for advanced-level bird-watching and wildlife viewing, or for any type of viewing where flawless color rendition is necessary. While more expensive than our 8×42 Sport HD, they are much less than competitor’s ED binoculars, and are truly an exceptional value. In fact SPACE.COM declared our Sport ED as “the one binocular to own if you can only have one.”

Magnesium-alloy construction with attractive textured dark green rubber armor, with red anodized trim. The focus wheel and diopter ring is aluminum (most other brands use plastic). Like the Sport HD Series, the Sport ED’s are completely waterproof. The internal focusers have the widest range of any Oberwerk binoculars, allowing them to focus as close as 6 ft. away! Oberwerk’s signature broadband multi-coatings are found on every air-to-glass surface (fully multi-coated), and the prisms are phase-coated for highest-possible image quality. The eyecups are continuously adjustable- simply twist to move them in or out. Includes right ocular diopter adjustment, soft rubber ocular cover, captive soft rubber objective covers, rugged nylon case, and neck strap.

  1. Michael Mann

    I’ve had these for two days now. Some of the key things I’ve noticed:

    My eyes are very relaxed and I can look through them for a long time. I attribute this to the a couple of things. Eyes don’t have to be lined up exactly in the center of the eyepiece to see the whole field of view – no black out if you are off center.
    Natural 3D view which I attribute to their precise collimation. Early or late, shade or sun, I see no “color fringes” on birds, twigs or any object in the field of view. They are able to focus precisely and have crisp detail. I don’t have a $1000 plus pair of binoculars to compare them to but don’t feel I’m missing anything.

    They feel compact, light weight and balanced to me. I have no trouble holding them stable enough. I don’t find myself looking for a place to brace myself to hold them still.

    Other observations: Large diameter focusing knob helps precise focusing. Field of view is probably not adequate for finding fast flying birds at close range, but fine for soaring raptors, flocks of ducks and geese and larger birds at a distance. Armor coating comfortable to hold. No wobble in hinge and it’s both tight and smooth. Once it’s adjusted, it stays there.

    Can’t comment on twist out eye cups as I use glasses and leave them all the way in.

    I would certainly recommend them and buy them again.

    I bought a pair of Oberwerk 10×42 Sport ED with a 6.5 FOV. I love them. They were great during our Antarctica trip and have been during the African Migration I am currently on. I’ve recommended them to others I am so pleased.

    I received the 8×42 Sport EDs a couple days ago. They came with a paper indicating Kevin Busarow’s (owner of Oberwerk) personal measurement of the alignment of the barrels. Out of the box, the Sport ED is a beautiful binocular to behold with it’s red, aluminum adjustment rings against the dark green body.
    Upon first use, which was daytime, I was amazed how light and easy they were to hand hold without shaking. They are much lighter than I remember my Swift HHS 8.5×44 roofs and with a wider field of view. I focused on a corner of a white roof and was rewarded with a view of perfectly aligned roof shingles. There was slight chromatic aberration but only at the edge of the field. It was less than half of the chromatic aberration of my 10×50 Ultras obviously due to the ED glass in the Sport EDs vs. the Ultras, which do not have ED glass. Neither binocular had chromatic aberration in the center. The Ultras had a lot more chromatic aberration at the edges.
    This morning, I brought my brand new Sport EDs to the local Audubon store to compare with their Swarovski, Zeiss and Nikon Monarch 7, each of similar specs. Still daytime but of birds at feeders–unfortunately through a glass window. The Sport EDs held their own against the Nikons. The Zeiss and especially the Swarovski’s seemed to be just a little more comfortable to use. Focusing seemed to take a little longer in the Sport EDs and that could be that the focusing mechanism was a little less smooth or maybe there was less depth of field but it was hard to tell. The ability to focus quickly is important in birding obviously. Hey, we are talking about $300 binoculars vs. $1.5-2.5K binoculars. As far as I could tell, brightness and sharpness were up there with both the Zeiss and the Swarovski’s. The Sport EDs were noticeably lighter than the other binoculars due to the magnesium housing and this is certainly a plus.
    Tonight, I tested the Sport EDs against my 10×50 Ultras and 15×70 Orion Resolux (same as Ultra) looking at Jupiter. Jupiter is a very challenging test for any astronomical instrument. Having these three binoculars gives me a nice range of magnification (8x, 10x and 15x). I had them on tripods and I was sitting. I have to say, although, of course, the image of Jupiter in the Sport ED was smaller, it was just a little sharper than either of the larger binoculars. As well, there was noticeably less chromatic distortion. Stars were pinpoint in all the binoculars.
    I was looking for a cheap birding binocular and was considering Oberwerk’s 8×40 Porros at roughly half the price of the Sport EDs. Kevin convinced me to go for the Sport EDs and I am so glad he did. Chromatic aberration is practically non-existent, which is important in birding. As well, there is no light loss throughput, which is important when it is getting late in the afternoon or when you are looking in the shadows. Kevin explained that these binoculars incorporate a robust prism system so that the binoculars are unlikely to fall out of alignment.
    I rate these Oberwerk Sport ED binoculars excellent and probably on a par with the Nikons at twice the price.

    I purchased the 8×42 SED primarily for bird watching. The binoculars sit on my desk which overlooks large window showcasing a tree with hummingbird feeder hanging from one of the branches. The 8×42 SEDs are perfect for the task. They are lite and very easily focused. It is easy to track the hummingbirds and re-focus as they go from branch to feeder to flower. The color is excellent, and the image is sharp. At night I use them to scan the night sky. Being 8x binoculars, they don’t have the power to tightly zoom in on the treasures of the night sky, but they are excellent for general scanning of the sky. The ED glass is worth the upgrade. These are wonderful binoculars. Highly recommended.

    I purchased the 10×42 model. The clarity is absolutely incredible throughout most of the field of view. I compared these side by side with a pair of Zeiss Conquests 10×42 (a $1000 purchase) and the view was, to my eyes, indistinguishable from each other. One of the slight differences was in the focusing knob – the Zeiss pair felt a slight bit tighter and firm, but I would have never had noticed had I not had a pair side by side. Overall, the Oberwerks Sport EDs really are comparable to a $1000+ purchase. These are the best purchase of optics I have made to date!

  6. Jon B.

    Buy with confidence! I ordered the 10×50 Ultra, but put a note with my order about my age and that I wear glasses, in case that was a problem. Kevin e-mailed me with some alternatives, since that model really isn’t good with glasses. I switched my order, and I’m very pleased with the 10×42 Sport that I got. The quality is outstanding, and I really appreciated the advice. Great buying experience.

  7. Peter G.

    My binoculars arrived today and I just wanted to thank you, they are brilliant, and just exactly what I have always wanted. They will be wonderful in spring and summer here, as I don’t tend to look at far away things as much, the brightness and close focus these have will make viewing Damsel’s and Dragonfly’s down on the riverbank (The Eden) an utter pleasure. I do like the anodized red aluminium and green colours you are using too. Thankyou so very much for what you are doing and bringing these things within reach of many people.

    I have to say thank you to Kevin who quickly responded to my Email about which model of the Sport ED binocular would best meet my needs. His suggestion that the 10x42mm would best compliment my vintage Canon 7×35’s was spot on. I got my new Oberwerk Sport ED 10×42’s two days ago and I have probably already spent several hours observing everything from birds to Jupiter and stars at night. These are seriously the best binoculars I have ever looked through and at this price, I know it knocks all the competition out. These are extremely well built and feel like they are built for a lifetime of use. They will be no problem to carry in my Jeep for all my trips up the Forest Service roads in the surrounding mountains. The glass is crystal clear and they weigh exactly the same as my old Canon 7×35 porro prism MIJ binoculars but feel so much more solid. Thanks Kevin for bringing such amazing optics to people at the most reasonable prices of anyone. I don’t see anything in the $500-$1000 range that rivals our has better specs than the Sport ED binocular. I would highly recommend these to anyone looking to have a set to hand down to your kids as these are built to last!

    I received the 10×42 Sport ED this past week and they are awesome. They were packed well and and collimation seems to be spot on. I really like the way they look and feel. The red color on the focus wheel and diopter makes it stand out with a unique look. Since it’s been very cloudy I cannot comment on how they do looking at the night sky. I did quite a bit of bird watching and compared them to my 8×32 Wingspan Probirder Ultra HD which for $110 is a very good binocular. Comparing both views while looking at birds about 50 feet away I could not tell much of a difference aside from the 8×32 seeming to be just a hair brighter. The 10×42 brought me closer to the birds and was as sharp as the 8×32. For terrestrial viewing I’d say the binocs gave me equal quality of viewing pleasure. Is the 10×42 worth almost $200 more? It is debatable but I like knowing that Kevin stands behind his products and I’m not rolling a roulette wheel when I order something so I’ll probably order again and pay a small premium. Inside the box I also received a nice Oberwerk neck strap, but unfortunately one of the belt slips on the strap was missing. I just took one off the from the other strap so no big deal. Great product and great company.

    I bought my 8X42 Sport EDs some time ago and carried them on a world cruise that sadly, was cut a bit short by the Covid-19 pandemic. Our three months at sea proved their quality and sharpness of view and light-gathering ability over and over again. Now I walk with them on my fitness eBirding walks during this time of social distancing and have found that the Sport EDs are the best birding binocular I have ever owned. Oberwerk’s service on this purchase and others that I have made with them over the years has been excellent as well.

    I was looking for an upgrade to my do-it-all binocular, and I wanted the assurance of quality that comes with shopping at Oberwerk (I hate wondering if my instrument is properly collimated, or if the focuser is going to start catching etc., and so far in this market range buying from Kevin is the only way I can rest easy on those points). After some extensive research, I settled on the Sport ED 8×42. My goal was a bit more portability than my other instruments, but also an instrument that would work very well for hand-held astronomy use. Like many others, this little gem changed my mind on the “roof for birds, Porro for stars” old mantra. The quality of the views through this well-designed and well-made bino is outstanding.

    The shopping experience was as I’m used to, from a comprehensive advice session with Kevin, to fast receipt of the item, with the trademark hands-on checklist included. The instrument feels really good in the hand, and screams “well-made”. Metal focusers, expensive-feeling rubber coat, and beautiful clear lenses.

    During the day I get very sharp images with great colors and contrast. Good immersive feeling as I scan through layers of trees next to my house, and they focus very, very close.

    At night, the views are really crisp, and the huge 8.1º FOV makes for a great floating-in-space feeling. I got a chance to check out comet Neowise, and wow, what a view! First off, I pulled it out even standing under bright lights on a road bridge, shielding my eyes from the flood lights with my hand! Then in the slightly darker spot, I got a brilliant nucleus, and about 3 degrees of slightly curving tail without any effort. I did some A-B checking with my other hand-held, the Celestron Skymaster DX 8×56. I still think the Celestron is a great instrument, but I am confident this (yes, roof prism!) instrument is actually better, in spite of the big decrease in aperture! I have yet to do a proper test in a dark sky to see how they pull in dim fuzzies – hard to do in my Bortle 7-8 skies, with neighbors who love their night lights. I could clearly see Albireo as a double! It’s a bit of a soft mess with the Celestron, in comparison, and I wouldn’t be able to tell it’s a double if I didn’t already know it. The coat hanger seems to be a bit brighter in the Celestron, but it is much crisper in the Obie.

    Overall I am very happy with this purchase.

    I have owned the 8 x 42 for 2 or 3 months now and they are an ideal all purpose binocular. They are solid and well made. They focus quickly and easily for birdwatching near or far and that was expected. The pleasant surprise was just how good they are for the night sky. These are easily handheld with minimal shake and the lenses gather more than enough light for the views that I need. They are great for when I don’t have time or feel like getting the 20 x 65 and tripod out. Views of constellations are crisp and sharp. They work great for searching out objects that are borderline naked eye sights. In the past week I used them to find the NEOWISE comet before attempting to see it naked eye and then eventually looking with the 20 x 65 and tripod. I also used them the morning that I looked at 5 planets viewable at the same time. Jupiter, Saturn, Mars, and Venus were all easily seen naked eye, but I used the 8 x 42 to “find” Mercury as it came above the horizon prior to being able to see naked eye. The sliver of moon in the area was just an added bonus. In short the 8 x 42 has done everything I expected and more. This is my second purchase and again prompt service and confidence that everything would be “right” was my experience. We have been pleased with the 8 x 42 ED and the 20 x 65 ED we purchased previously. I look forward to our next purchase, either something to fill the gap between the two we own or possibly a binocular telescope.

    Very nice binoculars. I was on the fence about these for a while. I was considering these and a handful of other brands. I can only compare them to my 10×50 Nikon Actions. The sport ED is much clearer and brighter. No internal reflection on the moon and no CA. Daytime views are crystal clear. I love the wide field of view. I’m pleased with the purchase. Maybe a 5 star if I had a chance to compare with similar spec binoculars

  14. Bob Boltz (verified owner)

    I’ve had the ED 8X42 for a year now and am completely satisfied. Recently used them to view Neowise and could the color and hollowness of the tail. Turning to Jupiter, I could see two moons. These are very solid and are half the weight of the old pair I inherited.

  15. Mike (verified owner)

    I picked up the 8×42 Sport ED model to use as an all-purpose binocular. My use is split about 50/50 between bird/wildlife viewing and looking at the stars, and I am very pleased with the performance for both uses. The binoculars are compact and light and easy to carry on a hike, and that same compactness and light weight makes them easy to hand hold while looking at the stars. Views are crisp and bright, and have plenty of contrast. The field of view is nice and wide and is great for sweeping the Milky Way. The overall fit and finish is solid, the focuser is very smooth with no backlash, and the collimation is spot on. Oberwerk as a company is great to do business with – shipping was prompt and everything was well packed. This is my second pair of Oberwerk binoculars but they won’t be my last, and I would happily recommend Oberwerk binoculars to anyone.

  16. William Ross

    I’m not an expert on using binoculars, but so far very pleased with this 8×42. It’s easy to focus and I enjoy being able to focus perfectly on insects on the glass window I look out of to spot birds. From what I’ve been reading it’s a great value for the price.

  17. Nancy Plumfield

    I use these binos for observing shore birds both wading and in flight. They were very easy to focus and the clarity was terrific.

  18. Raimund McClain (verified owner)

    These are well built, well designed, and the best value on the market. They were shipped promptly and came very nicely packaged. Highly recommend.

  19. Kevin C (verified owner)

    I recently bought the 8×42 Sport ED binoculars. Other than a set of image stabilized binoculars I own, which are in a different class due to their size, these 8×42 from Oberwerk are the best binoculars I have ever owned.

    I like everything about them – the weight, the feel, and the views. These are not so heavy that I can’t wear them around my neck for long periods. The coating gives me a good, firm grip. I am not in fear that I might accidentally drop them.

    It was easy to adjust them to fit my face, such as interpupillary distance and the right eye’s diopter setting.

    The center focus operates flawlessly, and I am glad that it is metal instead of plastic.

    The views are incredibly sharp. I use these for bird watching and watching other wildlife; I also use them for star gazing.

    I chose the 8×42 instead of the very similar 10×42 set. I could have gotten the 10×42 set for the same price as the 8×42. But as I get older, I find that my hands shake more than when I was younger. The Oberwerk web site mentions something about this when trying to choose which model. I already knew to choose the 8×42.

    As a plus, they are waterproof. I typically don’t use binoculars in bad weather, but it’s nice to know that I can if needed.

    I always wear my eyeglasses when using binoculars, both during the day and at night, and I have no problem at all with eye relief.

    Due to my budget, I am like most of you reading this review – I want a very good/excellent set of binoculars, but I also don’t want to spend $3,000 for something that may come close to optical perfection that I can’t notice anyway. I have never even looked through a so-called “alpha” brand of binoculars, because unless I win the lottery, they are always out of my reach. I am unsure whether I would really notice any big difference between an alpha brand and the Oberwerk.

    But with these Oberwerk binoculars, I feel like I have won the lottery and have money left over. Of course, there are more expensive binoculars in the same 8×42 size that may squeeze out a little more detail. But I don’t think I could discern such a difference. I am very satisfied with these.

    With these 8×42 binoculars, I feel like I am immersed into the view – both during the day, and at night. At night, the images are much brighter than expected. I am delighted with the views.

    Don’t worry about where these binoculars are made, and don’t concern yourself with where the alpha binoculars are made. Instead, worry about the quality control, regardless of country of origin. Oberwerk’s owner has a well deserved reputation, and he maintains it by ensuring quality control at point of manufacture. So I don’t care where these binoculars were made. I care about how they look, how they feel in my hands, how they fit my face, and how great the views are when I look through them.

    The one thing I regret about these binoculars is that I waited so long to buy them. I should have gotten them long ago. Thanks Kevin, Linda and the other people at Oberwerk for making a quality product at a decent price.

    I purchased the Sport ED 8×42 primarily for birding which I recently got interested in, but also for night sky viewing. I have been involved in amateur astronomy for several years so am familiar with optics and have owned many telescopes. The Sport ED binocular is simply wonderful. The build quality is exceptional, the focuser is smooth and has ideal resistance, the hinge is robust, and the diopter has stayed where I set it the day I received the binocular. I have a low/mid range 10×50 binocular that I have used for astronomy and birding and the Sport ED blows it away in image quality and comfort of use, I was astounded by the difference and no longer have a use for the 10×50. I think the perfect collimation plays a big part in comfort and immersive view. Coupled with the wide field of view and sharp optics it is a pleasure to use as well as functional. I have no experience with high-end binoculars, but am not sure how it could get much better than the experience the Sport ED provides.

    I have viewed through a lot of binoculars in my years. I currently own a pair of Nikons. They served me well over the years but after seeing what I was missing with these Oberwerk 8×42,10×42 Sport ED, there is no comparison. I love these binoculars and am now considering a larger pair for digging deeper into the sky. I am an Oberwerk fan for life. And the customer service is top-notch. I highly recommend these optics.

    First let me start by Thanking Kevin for his help. I’ve been emailing him with questions for about two years. He always responds quickly with good information and suggestions.
    I have a Celestron 9.25 Telescope, but it weighs a lot and takes about 20 minutes to set up and align. I was looking for a good pair of Astronomy Binoculars that would be lighter, easier and set up in just a few minutes. Like the 15×70 Ultra and 20×80 Deluxe III.
    I have always looked at the 8×42 Sport ED for wide view Astronomy viewing, but I already have a 10×50 pair. I really wanted a bigger, higher power Binocular for a more detailed look at the Heavens. But recently, my 40 year old Minolta 10×50’s had an accident. Although they still work, the image is not as good as it used to be. So, I started looking at the Sport ED’s again. I also looked at other brands like Celestron, Vortex, Zeiss and others. None of the other brands have anyone to talk too about their products. You have to send them an email and hope they get back to you in a day or two. Thanks to Kevin, I purchased the 8×42 Sport ED’s. And I’m glad I did.
    I’ve been using them daily and not just for Astronomy. I sit outside in the morning with my coffee and view all the birds in my yard. I’ve actually learned what kind of birds they are. I live in Eastern NJ and will be taking them to the many parks along the Jersey Shore.
    The 8×42 colors are natural, and everything is sharp. I can focus quickly to see amazing detail. I’ve only had a couple of good nights to look at the stars, and the view was amazing. Wide, clear and sharp from edge to edge. Can’t wait for the next clear evening. I even purchased a Gravity Chair for ultimate comfort at night.
    I love the size and weight of the Sport ED’s. It has a very nice grip and the focusing knob is smooth. I’m still looking at big Bino’s. And when the time comes to purchase one, I’ll be contacting Kevin. No reason to go anywhere else.
    These binoculars will be coming with me everywhere. They are a pleasure to use. Couple this with the Binocular Harness, which I would highly recommend, and you have an amazing, comfortable, tack sharp binocular that is a pleasure to look through, every time.

    Good viewing

    Outstanding binoculars and outstanding service!! I just received my 8×42 Sport ED and have used them for bird watching and will be using for wide field astronomy. They are tack sharp across the entire field and show no signs of chromatic aberration!!
    I also have a pair of vintage Japanese 7×50 binoculars and together with these 8×42 Sport ED’s, my binocular observing needs are covered for the rest of my life. I am an avid bird watcher and amateur astronomer and these 8×42 Sport TEd’s will definitely be put to good use!!
