Ive got both a meopta 6/26/56 on a 22/250 and a zeiss 4/14/50 on a 308 and being honest apart from a higher mag on the meopta i cant tell any difference the zeiss is quite a bit smaller in size and seems to suit my 308 which is quite a small lightweight rifle.I would be just as happy with the zeiss on 22/250.
I have 56mm S&B 's and 50mm Swarovski's you will not notice any light or sight differences just a less bulky scope
The sensitivity of the human eye is logarithmic. The difference in a 50mm and 56mm scope is smaller than the difference between a 60w and a 75w light bulb.

I've always gone for a 56mm Objective Lens but looking at the 50mm, I'm wondering how much of a difference the former makes for light gathering. Also, is the 50mm less bulky on the rifle in terms of general stalking.
Any thoughts?
+1 also doubting a fixed Swaro would be outstripped by a variable Leupold - suspect there is something else at play like age of lens coatings and scratches....Interesting - Leupold beating Swaro. I thought larger tubes only gave wider dialling, with minimal effect on light transmission?
What does that equate to in daylight time?.....5-10 minutes??....if so,thats a big difference.....
Sunrise is about 400 lux; civil twilight about 4 lux. While the true definition of civil twilight is when the sun is 6 degrees below the horizon, it's commonly taken to be 20 to 30 minutes after sunset. So a 10x difference gives you 2 to 3 minutes, while a 20% difference gives you well under 10 seconds.

I just cannot believe 20% = 10 seconds from light to dark in 50 seconds or how should we understand that?
I would chance to believe the practical experiences more than some dodgy theories. In some countries most shooting is done throughout the night using a strong moon with or without snow, in those areas the 56mm scope is still king for a reason.
