Summary: this set of binoculars is restricted to viewing objects/scenes/wildlife that are more than 20 yards away...the optics are very good and once set for an individual user's eyes, they are always in focus(no focusing is needed and no mechanism is provided) and give stereoscopic images that are typical of porro prism binoculars( a depth of field unmatched by even the state-of-the-art and most expensive roof prism binoculars..
Summary: These are great binoculars. When you look thru them it is crystal clear. Their shape is super comfortable to hold on to. The auto focus is an awesome feature. It works really fast. I would purchase another set in a minute and recommend them to anyone. They are worth the money!
Summary: I chose the binocular for running hunting, basically in mountains. The binocular should to requirements: good sharpness of the image, brightness, not heavy, convenient in options. Steiner Military/Marine 8x30 Binocular completely to it corresponds. At it a good picture, small weight-520gramm and it is convenient. Function a sports auto focus is well realised.
Summary: Very pleased so far. Good clarity and field of view. The binoculars are light in weight. With the auto-focus, target acquisition is quick. The only negative thing I can say is that when looking at objects under 100 yards, you can get some eye fatigue.
