    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.

    Note that if you're shooting RAW only, the previews are only ~8MP (3200x2400). If you're shooting Medium or Basic JPEGs, they're even smaller.

    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 :)
