Home Forums Hunting & Shooting Ask The Gunwriters Why has everyone gone ape over larger, i.e. 50mm, objective lens on scopes?

DMB, No need to be rude. I answered your question with my first sentence.

There might be a theoretical difference in that the 3-9 might have more lenses and be slightly dimmer due to more lenses but that difference is likely below the detection threshold of the human eye. Also the scope with the larger exit pupil will be more forgiving of eye position. You'll see the full image in the entire 11mm shaft vs the 4mm shaft of the smaller objective with 7mm of tolerance..............................DJ
