I can't seem to find a clear answer to this simple question no matter what kind of forum searching or googling I do:
When a camera states that it has a 3X optical zoom does that mean that the subject will appear:
A. As if you were 1/3 of the distance away that you actually are
B. 3 times larger in its image size by area (i.e. square root of 3 larger in either in height or width)
C. 3 times larger in its image size by height or width (i.e. 9 times larger in apparent area)
D. None of the above
I guess this must have been asked before but I couldn't figure out a good search term
Thanks
