Hello,
I’ve just been reading about your ED 20-60x82mm Spotting Scope. My friend has a set of Oberwerk Sport HD binoculars, and both the clarity and brightness are exceptional. Can I expect the same with your spotting scope even at max (60x) magnification? Do you have a showroom at your Dayton location? By the way, I currently use a Leupold 15-30×50 spotting scope for bird watching. Any comments on comparison will be helpful. Also, I assume that it has a standard thread for use with most any tripod on the market. Thanks.

Actually the Sport ED scope is a level above the HD Series binoculars (due to the ED objectives). The difference between the Leupold 50mm and the 82mm Sport ED is 270% more light-gathering objective surface area. With all that extra light, the view at 60x is remarkably good, and chromatic aberration is almost non-existent. Our scopes have a standard 3/8-16 threading on the bottom, and we include a 1/4-20 reducer- so they’ll work with any tripod. You’re welcome to come see for yourself, we have a small showroom in Dayton. Just give us a “heads up” before coming.

How would your product compare to a Swarovski or a Zeiss in terms of optic and image quality? Based upon the clarity of my friend’s Oberwerk HD binoculars, I get the impression that this ED scope, with the better grade objective, would be hard to beat. Is the reduction or near elimination of chromatic aberration a product of the lens construction itself or do other components of design dictate that result? Are the aforementioned brands priced to a certain extent on name recognition, or is there something I’m missing? With my Leupold scope, I see a loss of crispness at max 30x when spotted on a white bird most notably – a little fuzzy around the edges. Darker objects seem not to produce this at all. This is partly what I would like to improve upon while upgrading to a 60x scope.
Thanks again.

The Swarovski and Zeiss scopes are just slightly better, but only an experienced observer would be able to detect any difference. You’re paying a lot for the name, and also a better warranty. Those brands also have multiple levels of distribution, which also increase cost. The Sport ED is a great scope at a great price (direct from factory to us to you). Try it- if you’re not impressed, you can send it back.

Kevin,
Thanks for the help. I just placed my order.

Great! Let me know what you think…

Kevin,
Over the past months I’ve run the new scope through its paces. It is as good as you had described. The color fidelity is excellent, even at max magnification. From migratory waterfowl on the open water, emergent spring buds at the tops of tall trees, to Jupiter and its four Galilean satellites just this past weekend – superb.

Hello-
If you could buy only one portable binocular for terrestrial viewing would it be the Sport ED 10×42 or Ultra 10×50?

For myself, it would be the 10×42 Sport ED. Has center-focus, all magnesium/aluminum construction so is MUCH lighter and smaller, and chromatic aberration is almost non-existent due to the ED objectives. This is the only binocular I take when traveling light, because it can do just about everything, including astronomy, very well.
On the plus side for the 10×50 Ultra, while it is individual-focus (somewhat awkward when hand-held), the depth of field is quite good, so for objects beyond 50 yards, everything is in crisp focus- therefore not much focusing is required. The view will be a tad brighter due to the extra light-gathering of the 50mm objectives. The optics are superb (albeit with some chromatic aberration). It’s built like a tank, and should last forever. If you’re thinking about the Ultra, another to consider is our new 10×50 Deluxe. Has center-focus, is lighter than the Ultra, and optically is surprisingly-close to the Ultra considering the relatively low cost ($169). But for portability, my preference would still be for the 10×42 Sport ED.
