Hi, I tried to research on this but cannot find an answer. I love going to night concert and require a binocular. I am going to get a Zen-Ray bino due to the good review on them but I am unsure which one to get, whether should I get a 8X42 or 10X42 or 7X50.
The problem is I am now using my Fujinon 10X70 and feel that the quality is good. The only thing about is the weight. My question is whether I really need a exit pupil of 7X50 for concert purpose? Or do I just need 5.2mm in the case of 8X42 bino since 7mm I suspect is reserved for complete darkness. Or is 4.2mm (in the case of 10X42) sufficient?
