Cons: Some minor field curvature or coma especially when using them at night near the edge. Compared to fujinon 7 x 50 FMTX. Case it can be an issue getting out of leather case. Date to around 1990 I\'ve owned them for around 20 years.
Pros: Very good in daytime lovely 3d effect sharp focus easy to use and relatively lightweight. Focus very smooth. Used hundreds of times and lovingly cared for. These binoculars really show up inferior quality uncoated or partly coated vintage binoculars much sharper easier to use and brighter clearer images. Lovely feel to them coatings etc holding up well. Store in a hotwater cupboard in their leather case. Very good for astronomy with the milkyway overhead lovely contrast and black background.
Summary: A fine pair of quality binoculars made with good glass and well coated and corrected. Worth the money clearly vastly superior to cheaper semi or uncoated vintage 7 x 50mm binoculars.

Cons: None really, difficult to waterproof porro prism binos without adding bulk.
Pros: Exceptional build quality, optics are excellent, bright and clear. Ergonomics are perfect. Controls smooth and precise. Great all rounder and for low light/astronomy/air shows. Steady image due to 7x magnification. Very well made leather case. I have the CZ Jena 8x30 and 10x50 which are both excellent binos but these 7x50s are my favourite. My pair are.mint and was fortunate to get them for the price. Classic binocular and for me a case of less is more.
Summary: One of the all time greats and a classic binocular benchmark.
