That high a magnification might be too much and they are going to be heavy as well.
Do a search here for switch power or dual power or zoom binoculars. I was on a thread here on 24hr and someone liked their zoom Bushnell's.
Switch Power link I have the Leu. 7-12 switch power 32mm's. While they are excellent and all I need they are expensive. Even at half price they were in the $500 range you mentioned.
