Ok guys I know this has been discussed many times but here we go again.

 

 

Why is a 40mm objective lens better than 50mm ?

 

I think it has something to do with your pupil only allowing a certain amount of light.

From my basic understanding, an objective larger than 40mm on a 1" tube is like tits on a boar hog. The internal workings restrict any extra "light gathering" capabilities of a larger objective. The 30mm toobs can benefit from the larger objectives as their internal pieces are also larger.

I prefer the 40 mm for several reasons........It looks better (lower profile). Weighs less. Its lesser expensive than a 50mm. And when you compare the two, there is only a fractions difference in brightness. To me, there is nothing to be gained of any value, that would make any difference at the range or on the hunts!!
