@mothaibaphoto I'm using an Acer switch alpha 12 (2.3-GHz Intel Core i5-6200U CPU, 8GB of RAM, SSD 256). Maybe the specs help? You're right the Qualcomm Snapdragon 835 processors may not be powerful enough for a fluid experience. Hard to say until anyone has tried it.
Indeed Sandisk Extreme PRO 64GB and 128GB classe 10 95MB/S sdxc sdhc sd uhs-I U3 work fine. Was able to shoot non stop 30 minutes of footage in 4K on the 128GB one. Wouldn't say 4K is "noisy as hell" either. I've only noticed noise shooting at the end of the day with higher ISO. During the day with low ISO, I cannot notice any noise. Touch AF on the screen is amazing. You can also do touch AF on a windows 10 tablet using EOS utility. Connecting the 5D4 to the usb port of my tablet opens EOS utility. Select on the screen where you want it to focus, done. Magnification X5 and X10 works and is great, you can also start the recording touching the screen.Despite USB 3 potential limitations, the lag is not strong. Unless you're shooting sports events, I find it totally usable. Of course a 12 or 13 inch tablet is too big to be used as a field monitor if you're shooting on your own in the streets but useful on location or in a studio. The tablet I have has a USB C Thunderbolt 3 port as well meaning you can recharge your tablet with an external battery while you are using it. Soon, on Windows phones running Qualcomm Snapdragon 835 processors (and others) one will be able to install any windows deskop app: http://www.theverge.com/2016/12/7/13866936/microsoft-windows-10-arm-desktop-apps-support-qualcomm This means you could most likely have EOS utility on a windows phone and use it as a field monitor with touch AF bringing a very powerful feature field monitors do not have. I'm not a Windows fan but it could be a pretty cool feature on a phone.
@noipego I personnaly don't mind having huge files if they provide me with flexibility in post-production: RAW or LOG. Canon's 4K MJPEG is heavy and a lot more difficult to grade than raw or Log. MP4 H264 or H265 wouldn't be that much different to MJPEG to grade but at least much lighter.
I don't mind having huge files if they provide me with flexibility in post-production but Canon's 4K MJPEG don't. As anyone tried the Log Neutral (link above) on the 5D4? If so, would you be OK to share some of that footage? Having no peaking for me is just impossible, I hope ML will bring it to the 5D4.
The mjpeg file format for video on the 5D mark IV makes HUGE files. Really bad choice. Correct me if I'm wrong but if magic lantern manages to hack the 5D4, it would potentially enable raw recording but won't be able to enable recording in mp4 H265 for example? This could only be implementend by Canon, is that correct?
Shouldn't there be a 5D mark IV sticky thread in the Camera specific discussion? Starting with detailed specs of the camera? Current post was started before the 5D4 came out with rumored specs. May be a good idea to start a fresh camera specific thread?
