Is 8x32 or 8x42 the best Birding format?

[QUOTE="OPTIC_NUT, post: 3172041, member: 121951"] Now here's an interesting obsevation: ---If someone says there is almost no detectable difference between 7x and 8x (I differ with that, but...), one thing they find barely noticeable, therefore, is a loss of 23% of the light (assuming the same objective size). ---Now....if they also said that multicoatings made a huge difference due to brightness: they would be in severe contradiction with themselves. Just sayin... (this is also a contradiction if you say 32mm is about as bright as 42mm).. 7x keeps growing on me. Without it, I have to bring 6x and 8x, since I like each so much. 10x just for big-distance venues. 7x35 ... bright and light...back to the future. ;-) I am also getting biased by the stable of great 7x35s plucked from the dross. So I guess.....another write-in for 7x, but if you do 7x you might as well drop the objective for size. There are some 7x30s but there should be more. [/QUOTE]
