I may be a Canon fanboy, but I purchased a pair of Nikon 10x42 Monarch III DCF WP because I just do not see the logic in having to put batteries (!) into my binoculars.
I bought the Canon 15x45 IS lens about 10 years ago.
Still got them.
Wonderful glasses.
Would recommend any of this Canon range - except the 18x50 IS which I tried out - disappointed by the colour fringing and weight.
