It's interesting that you prefered the wider fov over the brightness gain. Thanks.
My takeaway was there was no perceivable brightness gain in the 50mm, which made the switch to the NL with larger FOV an obvious choice.
Both are far better than needed for legal shooting hours. I can generally spot animals 20-30mins+ outside of legal light with the NL, and quite a bit more if there’s moonlight. For one example, I spotted my buck this year at 260yds about 15mins before legal shooting light with the NL.
I just really don’t find enough benefit in going above 42mm for 10x magnification optics.
