What point is 100% zoom on a 5DII?

JimKarczewski · March 6, 2011

Seems like Canon doesn't post this info and it's not the easiest to determine on your own. Is going in all the way 100%? How about if you are shooting sRaw1? It still zooms the same amount so are you going in farther since the image is smaller?

Both Canon and Nikon (from what bodies I've had my hands on at least which is more Canons than Nikons) don't post a zoom % on their displays and it drives me nuts. Better yet, I didn't see it in the manual or online anywhere.

If I understand the question you are asking if the camera will zoom in image review/playback (or "Play" mode) to 100% or 1:1 pixels (captured:displayed).

If that's the question then the answer is that the user manual says that the zoom magnification for the LCD is from 1.5x to 10x. Since the LCD display is capable of slightly less than 1MPix (920,000 dots to be exact) and the maximum magnification is 10x, that means that the LCD display is showing "almost" 2:1 pixels, captured:displayed; probably around 43%.

Thanks Ziggy, must had missed that somehow in the manual. Back to look again..

It's in the specifications section of the user manual, page 215.

The LCD is 640x480 pixels = 307200 pixels. The 920K "dot" spec counts each RGB "pixel" as individual R, G and B "dots".

Thanks Norman. I see the "VGA" description now (which should have been the tipoff).

My new calculations imply that the LCD is showing 14.6102710205274% or a ratio of 6.8445:1 pixels, captured:displayed.

Roughly rounded to 15% and a ratio of 7:1 pixels, captured:displayed.

Would someone check me on this?

The pertinent information:

10x magnification for display

640 x 480 display

5616 x 3744 imager

If I understand the question correctly... here is an alternate calculation

for a 5616 x 3744 imager at 10x

561x374 pixels are being display on on the LCD.

If the LCD is 640x480 then each pixel is being display individually, with the caveat that something is being done to stretch things across the screen.

So it is 1:1 in the sense that the LCD at 10x has at least one pixel for each pixel in image.
