THE IMAGE ABOVE IS A PAID ADVERTISEMENT What do I lose in a 20-24mm objective - FoV, light gathering . . . ? With that small of an objective my first thought would be they'd be like looking thru a pin hole. But Leupold make a tactical 1-3x14mm for $1100 so I would assume you ought to be able to see something thru it for that kind of money. |

The human eye can only see an exit pupil of around 5 or 6.
Take the objective size and divide the magnification setting. This will give you the exit pupil for that mag setting. A 2.5-10x56 and a 1-4x24 can have the same exit pupil depending on what mag setting they are on. I would worry more about glass quality than objective size if you want to maximize light transmission. Also a 30mm tube does not transmit more light than a 1 inch tube. |
