There is a serious problem with double vision with these binoculars and the focus is very difficult to use and the quality of the linses is very poor.

I already have a pair of Canon IS binoculars and find the batteries run down quickly so I was looking for something that would give me a stable image without using batteries. The only thing I found were these 20x50 from Newcon. All the specs looked great so I ordered them. When they came I took them outside to see how well they worked. The following is what I found: 1. The unit produced two side by side images that I couldn't correct (I found out later when I called cust serv that this was a jarred prism issue and easy to fix back in their shop). 2. There was a lot of color around all bright objects. This means excessive chromatic abbreviation which is an indication of very poor quality optics. 3. There was no center focus as advertised. The focus was individual for each eye. This made it extremely difficult to switch between close and far objects or even to follow an object that was moving toward or away from you. These would not make a good unit to watch/follow birds with. 4. The right eye lens focus would focus an object fair but not as sharp as my Canon IS binoculrs would (I could see the numbers on a high altitude plane with the Cannon and with the Newcon the wings were fuzzy and there was no hint of any numbers). 5. The left eye lens focus would not come to a good focus at all (not even as good as the right focus which was very poor at best). The image through the left eye lens was not only very poorly focused it was also dimmer than the image though the right eye lens. Something very bad was wrong with the left side optics. 6. The unit would stablize a moving image (not rock solid like the Canon IS unit would) and the image seemed to swim slowly back and forth but this wasn't very bad and I could get use to it. 7. The image stablization became erratic for objects that were above 45 degrees in elevation. The unit failed to stablize at all for objects above 70 degrees elevation but instead would 'click' and then the image would snap to one side and then it would 'click' again and the image would snap to the other side and so on and so on over and over... I bought these for Astronomical use (at night at high elevation angles) to replace my Canon IS unit as it goes through too many batteries. The bright side is that when I called customer service they sent[...]to pick them up and are returning me another new pair that they will check out before shipping to me. I'll post another review when I get the checked out pair.

The product is next to impossible to set so your not seeing everything double vision. Optics seem to need some help. Stabilization works well but not much good if you can't focus.
