[QUOTE="480sparky, post: 272881, member: 15805"] Kinda wondering what the purpose of knowing the number of elements and groups of a lens is needed. All the manufacturers state this in their lens' specs, but....... why? What purpose does it serve? Can you tell the difference between a [I]FlareMaster[/I] lens 25-75 f/4 compared to a [I]Pincushion King PRO[/I] 25-75 f/4, judging the former by having 9 elements in 6 groups and the latter 10 elements in 4 groups?
