The new Oberwerk 25x100mm ED Ultra is the largest and highest-image-quality binocular we offer, short of the XL Series binocular telescopes. Like the XL Series, it has FK-61 ED (Extra-low Dispersion) glass objectives, which greatly-minimize chromatic aberration. In fact the view it provides is exactly the same as what you’d see with a BT-100XL-ED with the optional 22mm (25x) eyepieces ($2800).
With the Ultra, you can’t change magnification, and it doesn’t have the 45-degree view- but it’s roughly a third of the cost! Of course it has all the features of the other Ultra models, including precision floating-plate prism mounts, fully broadband multi-coated optics (all air-to-glass surfaces, including prisms), rubber-armored all-metal waterproof construction (nitrogen filled), braced and hinged objective tubes, and built-in mount.
This binocular has a wide 2.63° FOV (66° AFOV), with excellent sharpness across the entire field.
Eye relief is rather tight on this model, so it’s not recommended for those that need to wear glasses while viewing. However, the focus range of the individual focusers can handle the correction for most people that normally wear glasses.
Includes objective covers, ocular caps, and our exclusive Heavy-Duty aluminum-frame case!
Note-shown tripod not included.
