⭕ This is the famous B&L MK41 7x50 Wide Field binocular that was made in 1944 only, and in very limited quantities. Features gigantic prisms, oversized 5 element Erfle, coated eyepieces, and build quality that has never been matched. This combination helps produce super bright images even in subdued light. Color rendition is very accurate. And image sharpness across the entire 10 degree field of view is as good as anything. Optics in this pair are perfect inside & out and coatings are perfect as well. I just had this binocular serviced at Sudarth Optical where they collimated (aligned the optics), and greased the individual focusers which are smooth and precise. Center hinge is firn as it should be. Cosmetics are very clean. Rubber eye shield/headrest is in perfect condition.
