[QUOTE="Jeff In TX, post: 79291, member: 1522"] [ QUOTE ] Some simple maths 50mm lens - Area in square mm 1963,5 56mm lens - Area in Square mm 2463,0 Divide 2463/1963.5 = 1,254 OR put another way the 56mm has 25% more light gathering area than a 50. [/ QUOTE ] Chris in Madrid, It's not quite that simple, [img]/ubbthreads/images/graemlins/confused.gif[/img] but your math is correct! [img]/ubbthreads/images/graemlins/laugh.gif[/img] Also, scopes don't gather light, it's how much light can they transmit through the scope. Hope it helps, [/QUOTE]
