Starting this new thread to discuss about optics and brands. i am looking for information on which binocular in the price range of 5-7 thousand. Mainly for bird and wild life sightings. I have unsteady hand (shaky hands), hence can't go for weighty stuff which might strain the eyes during prolonged use. have been reading reviews on net, 8x42 or 10x42 seems to be apt. What at would you suggest and why ? Thanks much in advance.
