Canon 5D Mark III - Resolution Review

[jcs]

Received a 5D3 this morning: quick resolution test- [url=http://cinema5d.com/viewtopic.php?f=30&t=39795]http://cinema5d.com/viewtopic.php?f=30&t=39795[/url]

Here are the images from Cinema5D if you can't view them. First image is downsampled still (ideal case), second image is 1080p video frame. Both sharpened in PPro @33.

Thanks for that. Was expecting the still to be better. The camera does stunning stills. The video doesn't sharpen well, quite a lot of halos visible.

Was a quick handheld test, right out of the box with no settings changes. You can print out the test pattern here: [url=http://www.bealecorner.org/red/test-patterns/]http://www.bealecorner.org/red/test-patterns/[/url] (ISO 12233). Canon's internal sharpen filter appears to be some form of Unsharp Mask, hence the halo. When I have more time can try with camera sharpen turned off. PPro's GPU accelerated sharpen is a convolution filter (same filter applied to still photo has no halo). That said, the sharpened video playing back in real-time in PPro looks pretty good: not soft! 8). Try sharpening your footage in post with a convolution style filter with in-camera sharpen turned down/off. At this price point, there's really nothing to compare with the 5D3 right now (if you want to use your Canon lenses and FF, etc.).

I have noticed that there's quite a big difference between having sharpness at zero, and having it even just 1 or 2 notches above. Minimum sharpness does seem to turn it off completely.

Looks like sharpening digitally in post rather than in-camera is way to go with the Mark III. Please keep the tests coming sir!

Hi Andrew.

Do you think 1DX would be the same in terms of resolution? What we should expect?

Thanks.
