[QUOTE="Varmint Hunter, post: 76797, member: 313"] Here is my take on this issue: I'll start by stating that in my experience, optical resolution [b]far[/b] outweighs magnification in a hunting scope, everytime. I'll take a high quality/lower magnification optic over a mid quality/higher magnification scope when afield. Having a target animal appear larger but without great clarity is not nearly as important as having a crisp image with great clarity even if the target animal is smaller in appearance. As to light gathering abilty: As you have pointed out; with a smaller objective lens all you have to do is reduce the magnification a bit to allow the same exit pupil (diameter of light coloumn) as the larger objective lens allows. In low light conditions it would be unlikely that there would be much benefit of having a slight increase in magnification anyway. At dusk and dawn simply adjust the magnification to allow the maximum exit pupil for your use. Yes - a larger objective lens would allow you to set the magnification slightly higher if that was important. I might add that according to my opthmologist(sp), most adults will only dilate to a maximum of about 6mm, and that is in near total darkness. There is , however, one benefit of a large exit pupil (7mm - 8mm - 9mm) that you don't normally see considered. If your eye can only use 6mm of light (your max dilation), a larger column of light at the ocular lens will allow you to align your eye with the center of the scope easier and faster. VH [/QUOTE]
