50mm or 56mm is it bright enough to make it worth it???

[QUOTE="Jeff In TX, post: 79132, member: 1522"] It's been awhile since I've read and researched a subject such as this one, but I'll chime in and pull from my fading hard drive in the top of my head (or my *** as my wife would say). Brightness in scopes can be achieved in a variety of ways. High dollar scopes from top of the line scope manufactures use the best optical grade glass, top of the line coatings on all their lenses (internal and external). They also use multiple internal lenses systems, meaning many internal lenses. A S&B, Savorski, Zeiss as well as many of the other top manufactures have scopes that transmit more light with a smaller objective (40 to 44mm) than other scope lines using 50 and 50mm objectives. These scopes also provide resolution and clarity other scope lines could only wish to achieve. They achieve this by using multiple lenses systems with the best glass available. Cheaper scope lines state their scopes are just as bright as the top of line scopes and that may vary well be. However, what you make up for in brightness, you lose in clarity and resolution. Cheaper scope lines don't use as many internal lenses which allows more light to pass through the tube. But in doing so, they lose the clarity and resolution. So brightness and light transmission is only part of the equation. Hope it helps. [/QUOTE]
