I’m not sure how much I learned with the difference in magnification, but it was fun directly comparing them, wish I still had my 10X42 SF in the mix also. The focus action on the NL is far superior, and the CA control is slightly better, but the EL holds its own and then some. For the overall size and objective size, the huge, ultra bright, razor sharp image of the NL 12X42 is incredible, the only negative I found was a slightly fidgety (eye box) I’m sure due to the exit pupil. The EL has a somewhat cooler tint, but very natural looking to my eyes, and the totally flat field, or at least the appearance of a flat field is much to my liking, I’m fortunate to not be bothered at all by (rolling ball), I would also enjoy comparing the 10X42 NL to the 10X42 SV at some point. A 12X50 NL is something I would be interested in, the exit pupil would make for an (easier view), but with the obvious added weight.
