Be sure to catch how much better Canon colors look and better yet the 5D4's Shadows bodes well against A7R II but not so much when it comes to Highlights...
You mean totally worse in dynamic range..? But colors and sharpness is a winner.

@DeafEyeJedi

I prefer the girl in the video over 5d IV and Sony. Sorry, she's so cinematic! :)

A question to you, you can go to PM if you want: have yo seen a good comparation between A7 ii S (the best Sony for video. The crop factor in the 5d IV it's a big problem for my movies, I must buy new lenses. Except if king A1ex get 1:1 from the sensor... ;)

It's already 1:1 from the sensor.

5d4 sensor is  5760x3840 pixels
That is 1:1 or am I wrong?

mothaibaphoto

So you want 1:1 from the WHOLE sensor. Good luck with your dreams :)

budafilms

near 4k, without crop factor, DR 12, Raw 10 bits... it's more than enough for me.
THat's why maybe I should get a Sony Alpha, even, with that pinky colors.
I love Canon skin tone.


budafilms

In my country the cameras are very expensive. I can only.buy one each time.

This conversación is out off topic. Send me a PM if you want. Or a 1D if you are american boy ;)

Thank you.

Sorry I don't troll you. I'm in same frustration. No, it's not offtopic. It's all about MKIV - because it not looks as attractive upgrade for video work from MKIII even if ML will be ported on it. Due to many reasons: huge crop in 4K, rolling shutter, unsufficient write speed for 4K in RAW and so on...

Interesting views from Canon USA, in HDSLR Shooter interview:

Some talk about cards too.

Interesting article talking about the use of dual pixel RAW for AF Microadjustment finetuning in an upcoming version of FoCal:

Thats not accurate.  I use a SanDisk Extreme Pro 512GB SDXC UHS-I Card (SDSDXPA-512G-G46) in mine for 4k and it works perfectly.

Not sure which post you are replying to. I think it may be

And he is right about this. You are not recording RAW ...
RAW in 4k (native DCI 4k):
4096 x 2160 x 14 x 25 / 8 = 387072000 Byte/s = 369 MiByte/s

djkraq

Sorry I didn't clarify.  In the video the Canon rep said that you can only use a very, very specific card to record 4k.  He is wrong about that.  I wonder if ML can open up to export 4k through HDMI?  I say that because through my research, the HDMI tech used is capable of handling 4k.

And no Canon DSLR uses 24p HDMI output ...

djkraq

I saw that it was 1.4 a long time ago, but I guess they actually went with 1.3.  Sorry about the misinformation.

myown

It is a HDMI v1.3 - but this supports theoretically up to 1440p (2560×1440) maybe there is a possibility for more than 1080p....
Because of the CF Card Speed for me is a 10 or 12 bit Video Mode more interesting  :D

First of all: these incredible guys have to hack the mark iv.

-> If you need some testers: me and my mark iv are ready

SiSS

Does anyone know, or could someone please test, can you record 1080 to external recorder while simultaneously recording 4K internally?

myown

Sorry  i can't. I don't have the right hdmi cable and no recorder either...

@Simonwb
Thank you for the samples!
Base support has been added into darktable: https://github.com/darktable-org/darktable/commit/4c61a0b8725f34eb73d7d88828f4c1712e661ab9
If you want, you could take the same per-iso (please do enable extended iso range for this in camera :) ) set for mRaw and sRaw, and then i could add support for these modes too.

As for DualIso, at least for now, in darktable the base subimage is used, and any other sub-images are silently dropped.

@LebedevRI

I'm glad the samples were helpful.

Unfortunately, I can't shoot anything more for a few weeks as I'm away from home for work, but can come back to this mid-November?  I'll then have to ask you to explain more plainly what you want, or go back to A1ex's original request, because I don't know some of your terminology.

Log Neutral on the 5D Mark IV. Looks promising.
The video links to this thread:

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?

Nope.
You and I will be sitting back, hoping and waiting for that thread to opened by people who can confirm that ML will work on 5D Mark IV.
Who knows, that might happen next week, 2018, never.
