DV Info Net - FS5 and Atomos Ninja V

First hello everyone,

I've been reading a lot here for a little while and I'm super glad to finally be able to be part of this community. Let's share knowledge and learn from each other!

My first post is about the FS5 and the new Atomos Ninja V. Just to mention I work for more than 15 years in this crazy fast moving TV business. Some of you guys surely remember Beta SP and Digi Beta, well, I started back then!

However I was pretty excited to get my hands on the Ninja V. But then, I must admit I was a bit disappointed, missing SDI makes the Ninja almost senseless for the FS5, but then I started using the Atomos only as a monitor, and to be able to see SLOG and to expose without zebra and to quickly see the focus, make the FS5 a really professional camera and great working tool for me! If you compare the price of the Ninja V with the small HD 502...you get a very good monitor AND a recorder I guess

Now, I know you guys saying the FS5 produces to much noise because of not be able to go below 3200 ISO, all the 4k 8bit stuff and if you were to buy the FS 5 + external recorder why don't you just buy the FS7 right away....yes technically spoken these guys knows everything! but I've seen great film that were shots on Iphones and poor stuff shot on high end cameras. So it always depends, right? The question is what is your purpose?

Anyway, can please anybody help....
- What is the FS5 HDMI HD output signal?
What is the FS5 HDMI RAW output signal?

I have found one post, and I searched the whole Internet for weeks, this one answer was
1920x1080 4:2:2 8Bit....HD
1920x1080 4:2:0 8Bit....RAW

I tried to find out myself as well, but when I compare internally recorded files with these on the Ninja V. I can not see any differences (maybe on a 4k+ monitor I would, I don' know) So if anybody knows I would be thankful for that info.
And, yes I have seen the comparison of Mr. Jensen - credits for that.

And just to understand, if I record a file on my Atomos V in HD the XAVC is re-coded in a DNxHD codec is that right?

An other thing is...
Sometimes I have some kind of aperture flickering. With both Sigma lenses (18-35mm and 50-100mm,) but only at aperture 3,2 - 4,5. It looks like the camera jumps between to half apertures back and forth. Has anyone noticed this issue? I 'm using the MC11 E-EF converter?

Oh, I wrote way more I thought I would, but, why not :-)

see you guys!
