And now the official word we've all been waiting for...
That Cinema5D 'review' what a Canon sycophant.
Rolling shutter test
The hate that this camera is receiving is absolutely unreal. Alot of it I can understand, but why is everyone complaining so much about the resolution? They compare it to the A7rii, but after 30MP, a few MP here or there is barely noticeable. If you need crazy amounts of it, just go with the 5Ds.
Resolution?? That is the last thing a person might complain about! In fact, I don't think I have ever seen a single complaint about it not having more megapixels??
There is PLENTY of other things to complain about instead!
Nice to see that Canon is catching up from being two years behind to maybe 1.5 years behind.
There is absolutely no question that in terms of stills, the A7R II beats the pants off this cam.
@LPowell that video does seem to hit all the main issues.
One factor that has come to light since the 5D IV was announced concerns the way it records movie files. According to an article on the Canon USA website, the 5D IV uses the same Motion JPEG compression method as used by the EOS-1D X Mark II and EOS-1D C. This codec produces a separate JPEG image for each frame of video.
Since MJPEG uses the same kind of compression as JPEG does for stills, an extremely high bit-rate is required to maintain image quality. This means recording at approximately 500 Megabits per second, compared with up to 100 Mbps for competing cameras that use the more efficient H.264 4K codecs and record with the consumer-level 3840 x 2160 pixel resolution.
And whereas competing cameras capture the full width of the image frame in 4K movie mode, in the 5D IV, the 4096 x 2160-pixel 4K movie area is extracted from the centre of the frame, effectively cropping the full-frame view in order to eliminate the need for pixel binning. This helps to prevent the reduction in image quality and potential for moiré and aliasing that occurs with pixel binning as well as constraining image noise in low light levels. Full HD and HD movies are not cropped.
Because of the pixel density on the 5D Mark IV’s 30.4-megapixel sensor, the 4K ‘crop factor’ is equivalent to using a lens with approximately 1.74x the indicated focal length. The view would be similar to what you would see when shooting with a camera with an APS-C sized sensor. This cropping makes shooting wide angles rather challenging, depending upon which lens you use. However, you gain a small telephoto advantage, which can be helpful for close-ups.
In another video-related issue, the 5D IV doesn't include the Canon LOG function, which is provided in the video-orientated EOS-1D C, and allows recorded footage to be graded and colour corrected with professional software. You don't even get a flat picture profile, which is the consumer-level equivalent and is provided in 4K enabled cameras from Fujifilm, Nikon, Panasonic and Sony. So users planning to integrate footage recorded with the 5D IV into a current professional video workflow will probably encounter a few problems.
Professional video shooters need to be aware that you can't record 4K clips to an external drive via HDMI out. The only option available is Full HD (1920 x 1080), which doesn't have high enough resolution for grabbing still frames for printing (one of the main reasons for including 4K video in this camera).

Another so called DR prize, in reality it is more prize to lower ADC noise.
Difference between the main and auxiliary subframes is nearly 2x, or one stop, and that the auxiliary subframe can be used for highlight recovery (for photos).
I actually laughed out loud a little bit when he said that cropped 4k video was a decision to make sure that the camera doesn't fail in the field. It might have been a little bit less funny if other vendors hadn't been shipping cameras with full sensor 4k for ~2 years already (~1-1.5 year for full frame).
Sung to the tune of "Bringing in the sheaves"
"Failing in the fields, failing in the fields, we shall film rejoicing, failing in the fields."
