In all honesty if you adjust a center focus pair of binoculars like Loner mentioned to do you should have the same results. I've found that the cheaper the binocular and the more high powered a binocular gets the smaller their optimum focus range is. On cheap binoculars I find myself refocusing the image all the time but on my Cabela's Euros I'm good from about 30 yards to infinity. I had a pair of Vortex Kaibabs (I miss them so much!) that I could set from about 50 yards to infinity but with the higher magnification I found I could do slight focusing adjustments to get a clearer picture in certain lighting conditions.
I think you will be happy with whatever route you go, just don't buy the individual eye focus binoculars thinking they are the only kind that have a large optimum focus zone.
