Im sure this has been hashed over befor but do you realy need or will a 50mm objective rellay be any better in low light than the 40mm?????

Both scopes are VX-III

Yes.

 

No.

 

 

Both are accurate answers.

 

If it's a big, bulky gun and you need 10X in low light, it would be good to ahve. 

 

If it is a brush gun or stalking gun or something light and needs to track well and move quickly for fast shots, I'd recommend the smaller bell of the 40 mm.

 

I think the more pressing question is why are you buying a Leupold when something else will do just as much if not more for less money?

Some very good info in the FAQ Forum, but I'm not sure it answers your question specifically though.

Ok, heres an exit pupil chart, pick an exit pupil that applies and see which objective size allows the power you will want to use. At dusk the 40 will support 8x with no sacriface and the 50 will allow 10X. If you are using below the power on the chart you don't need a larger objective. Larger objectives are for allowing higher power use at lowlight periods without losing full exit pupil. The cost to use larger objectives are - more weight, require higher mounts, higher price, and larger size if balance and looks are of concern on a smaller rifle. The trade-off of course means the ability to crank up the power further in a dim light situation and the closer an object appears to your eye the better you can see it in low light....even with light transmission being equal.
