C400 focus peaking noise all over image

[Adtasa]

I got my C400 a while ago, it’s great so far but I’ve found a big issue with the focus peaking.

When you activate it it gives the entire image on the lcd a red cast or whatever color you chose in the menu. So not only does it make things in focus red but also all the noise present in the image. As soon as you turn it on the image gets noisier on the screen also. White is the only one you can use but it washes out the image and introduces a lot of grain to it.

Either I am missing something basic or there is an issue/bug with the camera/software. I have tried with different settings, but no matter what I do I always have this issue to a degree. it gets way worse if I crank up the peaking strength in the menu.

The C200, FX9 and FX6 I used to shoot with worked as it should with peaking, no issues there ever. This function on the C400 is almost unusable.

Anyone ever seen anything like this? Monitor LUT’s on/off makes no difference. Different gammas makes it either a bit better or worse.

This issue is not as visible in broad daylight on the monitor, but as soon as you have darker parts of on the screen the peaking color shows all over the place.

It sounds like both of us has a quite similar background when it comes to cameras. I´ve never heard about such a poor performing peaking to be honest. On my first gig where I had to use the 12800 ISO I was shocked when I saw the red cast on the entire image thinking that my WB was way off. 
As I´m writing this I´m updating the firmware on my C400 that should fix this a bit at least. Let´s hope for the best!

Update: The new firmware has fixed the issues I´d say almost completely, it is way better now! Now it´s just a question of tweaking the settings of the peaking so that you set it as low as possible but where you still can see it while focusing. Either way this issue has now been resolved!

Hey Adtasa,
Thank you very much for your information. I'm currently doing the update and am really excited. I was able to shoot with an Amira again today and was so pleased with the look and annoyed about my peaking problem, which I hope is now fixed.

It's done and I'm sooooo relieved.

Thanks again for your help.

I had a shoot with it today and I can confirm that it works great. You just need to be really careful with the settings because if you set the peaking settings to a high gain you will get the same issues as before. But now at least we can control that to a level where it does not affect the image any longer! 

Good luck with everything!

But would you say there is a setting where it always works, or do you always have to tinker with it?
I have now left it on the presets.

No I´ve set it to a certain strength now where it makes the peaking visible almost always without the image taking any impact or changing in color. My settings that I use are: Gain +5, Frequency +2. The lower these values are the better, but I found that if I went under any of these settings the peaking simply wasnt clear enough for my taste.
This settings is the one I will always use from now on, adjusting it from shoot to shoot really wouldn´t make any sense for me lol.
