Strangely enough the LED on my cam blinks shortly when removing one card (Transcend) but not the other (Sandisk). Both got the same version of Magic Lantern on them.

[VERY IMPORTANT]

But since the title is "5D3 & others", it is a bit misleading to write

VERY IMPORTANT
Make sure that in Canon Menu:
Image Quality = Raw

when this setting depends on the camera.

I'm just trying to improve the How-to

I think it should be mentioned that setting the image quality to jpeg allows you to record more frames (as the buffer size is bigger) on some cameras (for instance 7D).

I would love to know whether anyone has experience with these cards, too.
(I asked here, no answer yet...  http://www.magiclantern.fm/forum/index.php?topic=8254.0)

Has anyone had the chance to test these new Sandisk cards thoroughly yet? (possibly with a 7D?)

Are they as fast as the Lexar 1000x? Because these Sandisk cards seem to be cheaper than the Lexar ones (at least where I live).

Thanks!

Well i think it's the limitation of 7d's sensor. Since you used cropmode it's the worst outcome of the noise because of 1:1.
And btw blue channel is always the noisiest one even if you take normal photos.

So I reckon the noise might be a result of the crop mode, blue channel, me adding to much contrast in post and me pixel peeping (at 400%) for too long
Nevertheless, the 7D still produces some great looking images.
Thanks!

I have recently installed Magic Lantern on my 7D (britom's build from 29/09/13) and have been testing it quite a bit. Works great so far!
However, in some of the raw videos (of a low contrast scene) where I exposed to the right completely (without clipping of course) I noticed a strange noise pattern (vertical stripes for example).





This frame (100%) was taken at iso 100, 2044x868 in crop mode, 23.976 fps override. The left part is the original, the middle part the normal edited frame (in ACR) and the right part a more extreme edit to show the pattern. Frame (.Raw) converted to .DNG with RAWMagic.

Am I doing something wrong or is this just the "normal" cmos sensor noise? Should I not expose to the right that much? (the image looks white at first glance)

Cheers
