Hi All,

          While on the subject of binoculars, I am wondering whether 10 x 42 is 
the best magnification x lens diameter combination for gloomy forest conditions 
or other low light situations where the quarry is not more than about 30m  away 
from  the observer, and magnification is not the major requirement.         
           Would optically equivalent (in quality) 7 x 50 give better light 
sensitivity and colour discrimination than say 10 x 42 or 10 x 50 ?

            Close focus distance and rapid focus also relevant, as well as 
waterproofness in rainy humid conditions if not for scuba diving.

                                                 Any suggestions?
