You can wish for whatever you want, hey I'm not stopping you.

The point I was trying to convey is that in many cases people have already got what they are wishing for, if only they stopped to learn what they've got (or read the manual as Skimask would point out) to realise the fact.

In post #1 of this thread you wanted a function, and got it in post #2 with a simple math statement. So if it's that easy, why bloat-out the core function with unnescessary code?

Your camera in this case already has the zoom facility... you've just not discovered how to use it yet. Rather than have an obvious button called Zoom, it's embedded several Menu levels deeper down and needs a better understanding of the camera to discover all it's features.
