40mm vs 50mm how much advantage

Quote:
There are quite a few people who deem 50mm does not offer any better light gathering capability. What do you say about 32mm vs 40mm. Do you see the difference there?
My eyes are not that good and I cannot really tell the difference in bell size. However, I can tell the difference between a 40mm Nikon and a 50mm Simmons and 50mm Swift premier (all at same magnification setting). The 40mm Nikon came out way ahead of the other two.

you got to remember that lens coating plays the MAJOR role in optical image quality too. that was probably what you were talking about since nikon would have better glass than simmons. you'd have to compare equal quality glass. no regular tasco glass would come close to simmons for example.
 
I've got leupold 6.5x20x50LR on a 6.5x284 for LR varmit shooting liked it so much got a 4.5x14x50LR for another varmit rifle. When I got those scopes I didn't even consider the 40mm bell or even look at one, I kind of considered if I wanted a 40mm bell I'd stick with a 1" tube and so far I like the 50mm on those LR scopes. Well good luck.
 
I've been following this thread for a while, just observing, not intending to post. The previous post (Roper's) struck me as a perfect example of how objective size is a matter of personal taste. There is no correct answer to this question.

It's like Seinfeld's Bizarro world. I too have a Leupold 6 1/2 x 20 LR, but mine is the 40mm. Like Roper, I liked it so much I just bought a 4 1/2 x 14 LR for another rifle, again a 40mm.

I have a couple rifles with 50mm objectives, but after buying the first 40mm I doubt I ever buy another 50. It's a matter of individual preference and I prefer the 40.

To each his own, both will do the job.
 
+1 for the 40mm. I've had a few 50s and didn't care for them for all the same reasons mentioned. Saw no advantage. Probably won't buy one again.

Good hunting
