Leupold 3-9x50 on my stalking rifle, bought as used from flea-bay at a very good price since I was shooting mainly air rifle at the time I started the transition to stalking. Since I was used to higher power/lower priced scopes on air rifles I was very pleasantly surprised at the low-light performance of this scope.
As far as age deterioration I can say that I have noticed a marked difference over the last few years (now in my 65th) but impossible to quantify.
What I can say is that the Leupold allows me to see much more for longer in failing light conditions. This was demonstrated one night on the rabbits that were colonising the club backstop. The other guys were mostly using the normal good-quality scopes fitted to their air rifles but started to experience difficulty when I still had a clear sight picture. They were all impressed by the difference. I was shooting on the lowest power at the time.
As far as I am concerned, + 1 for the exit pupil effect.
