Seeing dpreviews tests comparing the jpg engine of the mkIII it makes me think that this is related to the video resolution being on the soft side. the video is probably taken through a similar pipeline as the jpgs, just with a different target resolution.

Here's an odd thing.

Took the EOS5 Mk3 for a walk tonight, took some Raw and HDR images along with a few seconds of video - checked them on the screen for obvious duffs.

Took both cards out of the camera to check the files on a bigger screen --- there not there!!! Took a couple of HDR shots on the same cards to check, all working.

Just the files from earlier today missing ...

Haha you jerk. You never worked with raw yet - did you? RED workflow is not even a little bit as fast as the one of the C300. With the Canon you can go directly in post - without grading, without proxy and without buying additional disk space... BUT.. both are very lovely cameras with awesome picture!

There are rumors of a global mk111 return to factory recall by Canon, anyone else heard this?

This Adorama comparison between the 5D Mk III and the Nikon D800 does seem to suggest that the Canon is superior when it comes to reduced noise with higher ISO. The Canon seems to have slightly better DR too. What do others think?

I'm sure the 5D3 is another amazing stills camera, as is the D800. The video in daylight is still behind a GH13, let alone a hacked GH2. The fantascism on the C300 really makes me scratch my head, for the same price you can get RAW 4k with the scarlet, and the workflow is just as simple, maybe even simpler.

On a high-end PC, you can edit gop1 gh2 files just as easily as Scarlet X files. Drag and drop in Vegas Pro, apply realtime GPU effects, oh yeah - and change any and all settings WB, ISO, etc etc all on the fly.

Full frame for video does have its fair share of goodness even tho its upscaled 720p. But buying it for video is absurd at the moment unless you simply shoot low light. I hope Canon would reconsider and release a magic firmware update that simply unleashes this beast, they cant be beaten by freaking Nikon that knows nothing about video. I'm still buying a 5D3 when i can get my hands on it since its a awesome stills camera. Changing to Nikon would have cost me too much. I'm sure i will be pleased.

Let's not to make it into anti 5DMkIII topic :-) I am sure that it is very good camera. They have troubles with sensor reading and rescaling, but I doubt that this is an error. More probable is that full frame sensor still can't fully sustain full readout.
Nikon seems better, so we hope that Sony will be also very good.

And in photo all this cameras are amazing.

It is comical seeing the Canon Pr in action lately. On one side the Fanboys convincing themself and others that the sharpness is better by using all type of sharpening vs not sharpen video from other cameras. An on the other, some well known blogger backtracking from there original thoughts. I would like to see those sharpness applied to the human face and beings, I can guarantee you that it will be ugly. It is easy to saturate or sharpen landscape, but try to do it to human beings.

I've had my EOS5 Mk III for 4 days now. Getting round to switching off all the automation and getting close to good results.

These were in very dull conditions -- have some better from this evening, will sort and get them up sometime.

Will be doing some video tests later this week.

First post, spec sheet, SDXC only. But UDMA capable CompactFlash can be very fast.
