Binocular With Autofocus, How Does It Work?

Thu May 27, 2010 7:30 pm

Hi all,

Some time ago I found out there are binoculars with auto focus. Last week I finally had the change to use one. This system seems to work perfect. Since these binoculars are not powered in any way, how does this system work?

I've looked through many website, and really tried to figure this out. Can any of you please help me on this?

Thanks in advance,

Vandenheuvel

The autofocus thing is a marketing lie.

They are just permanently focused to infinity. That's all there is to them.

Fly2HMO, thanks for your help. I guess thats the only way this can work. These auto focus binoculars should actually be cheaper!
