Crop mode questions
 

Hi guys

I was just wondering if the moire and/aliasing artifacts are also present on the crop mode? Should these be eliminated if crop mode does not have to use line skipping etc?

Also if Canon were to introduce a 1080p crop mode - what would the magnification be? (if 480p is 7x)

I believe that the crop mode still does line-skipping or pixel-binning. That's what should be happening, according to math. The crop mode is 7x magnification, which means that the cropped image area is 1/7th the size of the whole image. 1920*1080=2073600, and 640*480=307200. Do you see?

The resolution of the sensor is 4724*3832. If you don't do line-skipping or pixel-binning, then the center 640*480 pixels would be a tiny fraction of the overall image.

Thanks for that - I see!
So 4724*3832 = 18102368
1920*1080=2073600
18102368/2073600= 8.7

So a 1080p crop mode without pixel binning/line skipping would be a magnification of 8.7 - shame!

Perhaps a 3k crop would be better?!! (3.4 magnification)
How does the red camera do sensor crop - do they bin pixels too?

RED doesn't do pixel-binning of any sort, AFAIK.
