The Oberwerk SE (Special Edition) Series are based on the discontinued SE models from a well-known Japanese brand. Our SE's have the same ergonomic and lightweight design, but we improved the optical quality by using FK-61 ED (Extra-low Dispersion) glass objectives, which eliminate chromatic aberration (false-color fringing). The 12×50's wide 5.5° FOV (Field of View) is also wider than the discontinued 12×50 SE. The 12×50 SE is the largest of the SE family, with rugged construction and precise center focuser, which can focus as close as 20 feet away. Of course they are fully broadband multi-coated, waterproof, and nitrogen charged. Includes a rugged padded soft case, caps, and a neck strap.
