I'm not sure how in depth this stuff is. But I was looking into Moire on the 6D and I saw this post on the downsampling algorithm that the 6d uses as opposed to the 5d3 and I was wondering if this was something that could be addressed in a magic lantern build or not. Here is the quote I found on it.
"The 5D3 is, when cropped from 3:2 to 16:9, is essentially a QFHD sensor -- exactly 4 times the size of standard 1080p HD. The reason it looks good in 1080p mode is because the camera only has to combine 4 pixels into a single pixel (pixel binning). This is the exact same thing the C300 does to look so good. The 1DX has a smaller sensor that isn't a simple multiple, but it has very powerful processors to downsample in a high quality way. The 6D has a smaller sensor but doesn't have the processing power to downsample correctly (presumably) so Canon just throws out various lines to create the smaller image. It's less processor intensive but results in interference patterns. That's why the 5D3 looks great with moire, the 1DX looks almost as good, and the 6D still has the same problems that the 5D2 had.If it turns out that the processor is strong enough to downsample properly, it could possibly be adjusted in a firmware update that rewrites the downsampling algorithm. Is it likely that Canon will do that? I'm not counting on it."
Just a thought. Thanks for all you guys do.
