[QUOTE="Grumpah, post: 3074374, member: 128746"] In my experience EVERYTHING is dependent on the quality of glass. I have had much better successes with a smaller diameter quality lens than a larger diameter lens of less quality. Lens coatings also seem to come into play. Generally speaking, I don't think there is a definitve answer to your question. In the case of rifle scopes, the thought that a 50mm + objective lens gathers more light than a 44mm or 40mm objective lens is simply a myth. Anything larger than a 44mm is only marketing fodder. Same with scope tube size. All a larger scope tube does is give you more OA adjustment and has nothing to do with gathering light. I assume lens sizes apply for spotting scopes as well. It's all about the quality of glass and lens coatings. Of course, this is just my humble opinion. [/QUOTE]
