how to many the zoom in mm to the "x" one?
eg, what is 12x zoom equivalent to? 12x = 300mm??
actually, how to calculate one?
depends on the widest angle. there's no fixed value for cameras.Originally Posted by Paul_Yeo
it's different for binoculars where the base is 50mm.
Use your longest end and divide by the widest end .... for example .... 28 - 300 = 300 / 28 = 10.7 = 11xOriginally Posted by Paul_Yeo
Yeah, but pretty useless to calculate in zoom factor.Originally Posted by Paul_Yeo
Your 70-300 is longer reach than your 24-120VR and yet it's only 4.2x vs 5x.
I have a couple of 1x zoom..

But u should be the richest.
As ESPN says, for SLR lenses, is a pretty useless measure. More relevant to talk about focal lengths.Originally Posted by Paul_Yeo
if you meant the panasonic fz20, its a 36-432mm lens (35mm equiv) lens. It is actually only 6-72mm but can achieved 36-432mm (35mm equiv) due to the 6x cropping from a smaller sensor size.Originally Posted by Paul_Yeo
