[Re: xcy]       #5633358 - 01/20/13 02:43 PM Edit   Reply   Quote Quick Reply   If you keep the comparison simplistic, à la the Adler Index, they are pretty similar with a slight advantage to the 15x70(63). (true aperture in parentheses) The Adler Index (described here) is the product of mag. X square root of aperture. Variables can be coatings, reflections, optical quality of lenses, etc. 16x50(48): 16 x Sqrt 48 = 111 15x70(63): 15x Sqrt 63 = 119 Rich Post Extras:       Pages: 1 Previous   Index   Next   Threaded   Extra information 11 registered and 44 anonymous users are browsing this forum.
