Optically excellent with only the outer 10% of field showing out-of-focus. It was perfectly collimated. The focusing is very precise and smooth. They seem rather tall compared to others but I think this is because of a high f-ratio to improve color correction. This is an excellent, solid binocular. I think it compares favorably to ones costing far more.
Pros: Visual quality, ruggedness, solid feel
Cons: Physically large
