I have 75-300mm lens.what kind of magnification will i get on crop sensor.this is a canon lens, so assuming a canon crop sensor on canon camera. I was told it would be 480mm. But what i am interested in is in times. Like i have nikon binoculars with zoom from 8 times to 24 times.it is really good zoom on binoculars.also have 12 times zoom on panasonic cam corder.these are good zooms.
I want to know what kind of zoom will 480mm lens will equate to in those specs like on binocular and cam corder. Sony bridge cameras also have zoom in times.
Second question is, if i get a spacer for that lens, 70-300mm, what kind of zoom then will it be? Will a picture still be usable with a spaces, because there would be less light i presume.
