I see a lot of expensive rifle scopes with small lens size such as 1.5-5 x 20mm.
Or perhaps 25mm. I always thought that the larger scope lenses like 32, 40 or 50 mm were preferred. Can anyone explain why these smaller scopes might be better?

This was asked recently in another thread. This should help shed some light. http://www.opticstalk.com/topic31665.html

Thanks, that was a pretty interesting discussion even if it did not settle on just one answer.
But having said all of that I'm still thinking that a larger lens will transmit more light all other things being equal. Someone correct me if I'm wrong but that has always been my understanding.
