zoom to x? equals 100% on 645D?

When zooming in on a captured or digital preview image on the LCD of the 645D, the choices range from 120% to 3200% - and it is great that you can select which percentage to jump to on the first click (instead of having to zoom through several to get to where you want to be) - but which magnification is equal to viewing the file at 100% on a computer screen? Is it x32? (3200%), or something less? I love this feature, especially being able to do this with a preview capture (with highlight warning and histogram) that is not written to the card. Thanks...

I *think* 100% = 20x on the 645d, since it has the same screen as the K-5 and 2.5x the resolution, but I could be wrong (on the K-5, ~8x is 100%).

Thanks Adam. I decided to pull up an image on the computer and match to the magnified view on the camera. Looking at a 100% view on the computer screen and comparing to the enlarged view on the LCD it looks like somewhere between x27 and x32 is a good match - since the camera only allows x16 or x32 to be set for the first click, x32 will be close enough! I'm coming to the 645D from a Phase IQ back where you can just tap on the screen twice to get a 100% pixel view, so this feature on the 645D is great to have!

I just checked a picture on a 27" monitor and I would say that x14 comes closest to a 100% magnification.
Also x11 and x16 are both very close.
x32 is more like 200% magnification.

That's what I figured. I usually look at 11 x for focus accuracy

Thanks for your thoughts guys. 30% is closest to the same size, pixel for pixel (assuming a monitor that is properly set up relative to resolution), but I agree it seems more accurate at the smaller magnification as far as judging focus goes. A nice feature for sure...
