I'm hoping that someone more knowledgeable than myself can help us interpret this.
Here is capture from the same source video as in the resolution chart tests that I did (video linked above in this thread). In this capture, the video is on the bottom and the still (scaled to 1920x1080p) is on the top. I applied an EXTREME amount of sharpening to the video (more than anyone in their right mind would even dream of applying to real shots) and some to the still.
Under the theory (as I understand it) that sharpening cannot create resolution, I wonder what is going on in this chart? There are distinguishable groups of lines near the "10" (1000 lines) mark.
Does this mean that the 5D3 might have more true resolution than we think?
Hey Jason- as the lines approach the resolution limit of the camera, the information begins to alias. As we move farther right, the aliasing becomes so strong that we can no longer see clear black-white line pairs. The limit in your chart example is around 850 lines, which is consistent with every other line chart test I have seen (including my own). The lines you are seeing past 850 are aliased and so-called 'false detail'. At one point based on your vimeo test I estimated 890 lines, however 850 is probably more fair. 1000+ would be nice but 850 is good enough for now.
I too have asked to see a line chart with the NO-OLPF mod. My guess is that it will show 900+ lines. I estimate that removing the OLPF might not alias too badly for video based on the low-pass filtering effect of pixel binning (2x2 or 3x3, etc.). Also requested pan shots on high detail image- sounds like they are coming.
It's possible to have the OPLF mod done for $450 by maxmax.com. They'll also put an optical glass in place to keep the optics correct. Ideally they'll find a way to also make the dust cleaning system work (or perhaps Canon will provide the parts, including optical glass, to make this work: another way to make a buck).
