That's more useful in the long run, and more actually useful to the person who asked the question. Often when I talk to new photographers with this particular question, they imagine that there is a complicated formula, or maybe even something particular to each lens and no formula at all. So, I know from experience that the further explanation here is really valuable. I can add it as a separate competing answer, but I figured you could probably cover it. :) | |

| Apr 3, 2014 at 14:18 | comment | added | Morpho | Why do I have to add this? :) The person asked the question wanted to see samples. | |
| Apr 3, 2014 at 14:14 | comment | added | mattdm | This answer would be significantly better if you described the simple math in going from one to the other. That is: zooming is just like cropping, and going from 200 to 300 is like taking the center ²⁰⁰⁄₃₀₀ths — or ²⁄₃rds! — of the image. Teach a person to fish, and all that.... | |
