a big scope is actually detrimental and will get you killed jiffy-quick where those are intended to be used. the small tube diameter scopes are meant for hunting dangerous game and are used much like an acog with both eyes open for extremely fast acquisition when being charged by something like a lion or cape buffalo or brown bear.
light transmission has little to do with the diameter of the objective and everything to do with the quality of the glass and its coatings. take that little nikon african and put it side by side with one of those big objective redfield/bushnell scopes you see at walmart for 39.99 in the clear plastic container and the nikon simply blows it away. yet on the description of that el-cheap 39.99 you will see claims of excellent "light-gathering" its pretty much hokum.
magnification levels combined with tube diameter give your field of view. the smaller the tube the smaller the field of view at a given magnification.
what makes the small nikon african 1-4x so great for some things is they are lightweight rugged as hell have great glass dont lose zero under extremes of recoil or abuse and dont cost as much as some other scopes.
