A most unusual Binocular. Yes, the outer field of view is not sharp .... But... This Binocular also has an extremely wide field of view, smooth accurate focusing and very good central sharpness. The view is quite pleasant and immersive as long as you don't need to wear glasses - the eye relief is too short.
Robust construction, quite large and heavy for a small aperture binocular. However, the combination of low power ( 5x ) and large frame provides a bright steady view and fits my hands very well.
Great product for its uncommon features. Price was good too. Just note the objective lenses and optical tubes are MUCH larger than typical 25mm binoculars. Probably had to do that to achieve the wide angle (like camera wide angle lenses).
So far so good. Having been using it for a week now - here is what i like so far
1. Pretty sharp and easy to focus.
2.Feels rugged at the same time it is relatively lightweight
3. Small footprint (its very compact). Fits in my camera bag easily.
4. Has really wide view so easy to trace moving objects.
The optics are great, no soft areas, no chromatic aberration. They are a bit heavy for the size, 1.26 lbs, I attribute that to the size of the internal prisms. These are my new go-to binoculars, over my Nikon compact and my heavy 7x50 astronomical Celestron. Wide field, great for sports games, I am very happy with this purchase.
