When i want to look back a pic, i guess that i have to enlarge it roughly 14 times, right? Backscreen around 1mpixel, sensor around 16 mpixel. Or am i overlooking something?

I think the answer is about 4 times.
Here is my calculation.
A photo is 16MP.
The LCD is 1MP.
So a linear magnification of 4 on the LCD will display 1/16 by area.
1/16 of the area is 1MP, and the LCD is 1MP, so it will be displayed at 1:1.

However the pixels are very tiny, so you may need to magnify more than 1:1 to actually see them.

Close 'nuff for me. ;) I don't see much need for knowing exactly where 1:1 is. xD

Doubling the size adds 4x the pixels. That might help you in your calculations.

I wasn't realizing the square factor from magnification to # of pixels. Thanks, also for the warning for the max pic dimensions... I can still do much better in RTFM :)
