Micro Four Thirds lenses and magnification factors
Apr 4, 2012

Can someone please explain to me how to convert the focal lengths of Micro Four Thirds lenses into magnification factors? Theoretically, I know we divide the bigger focal length by the smaller one, so the 14-42 mm lens has a magnification factor of 3X... but then the 45-200 mm has a magnification factor of only 4.4X... I do understand the difference at the smaller end, meaning that the 14-42mm lens can focus on nearer objects (macro) more than the 45-200 mm lens... but I just cant grasp how the opposite works, cause I am sure it isn't only a matter of focus, but of magnification as well.
I am just too confused, I guess... and my physics is really bad
Would appreciate your help.
