[QUOTE="Sako7STW, post: 492880, member: 2112"] No, that is only partially correct. Only so much light can pass through the smallest section of the scope period. Think of it kinda like the old saying, "A chain is only as strong as it's weakest link." Only so much light can pass through a given tube. Most people think that the 30mm, 34mm, 35mm, and so on tubes are what the light has available to pass through. If you look at a scopes structure though, you will see there is a tube within the outer tube. The inner tubes job is to refract light for magnification purposes and to reverse the picture. In most cases the inner tubes lenses and tube itself are the same size on a 30mm as a 1" and so on. The larger outer tube provides more inner space for the inner tube tube to move in, allowing for a larger adjustment range. That is the purpose of the larger tubes A larger objective lens allows for more light transmission at higher powers in dimmer conditions, thus maximizing the available light at the exit pupil giving you a "brighter" picture. It can get pretty dang complicated and I will spare you but all in all, your friend is wrong, especially about the Minox and any scope with 1" tubes. If your going to be hunting in low light situations, a larger objective is the only thing that can really help you besides paying big bucks for better coatings. But they come with their drawbacks as well. Hope this clears things up for you some. As for your needs, I would recommend strongly looking at the Zeiss Conquest 6.5-20x50mm or the 4.5-14x50mm.
