EVA1 Dual ISO Speculation

Ok, I am very excited about this new camera, 5.7K, internal ND's, 4K out(perfect for additional recording options and 4K monitoring.
Here is the big one dual recording, I have had the fortunate opportunity to shoot with the LT and 800/5000 ISO is something I thought I wouldn't use, I was wrong...it's terrific and works beautifully.
My thoughts is that the EVA-1 will do 800/2500, I have no info on this, just a hunch. My guess is that one, they have to leave something for the Varicam users. Second, the amount of power required to do this, the full sized Varicam loves the batteries, the LT much better...My guess is that unless Panasonic has figured a way to reduce power consumption the higher ISO will be much lower...say 2500-3000, providing they are using the traditional dual ISO method of the Varicam. I am thinking they are using some sort of advanced NR, either way this will be a game changer for me and help with my travel. Please note, I am not an engineer, this is all speculation...Any thoughts?
 
First thought: This shouldn't be posted under the Varicam since they are not calling it a Varicam. ;)

Second thought: My guess is that they'll use the same method but adjust it for more pixels and less power. What the result will be we'll just have to wait and see.
 
A couple notes.

The VariCam sensor cost a fortune to develop and manufacture. A significant part of that cost is the Dual Native ISO functionality. It is built directly into the sensor design. Panasonic learned a lot from creating the VariCam sensor and have applied this knowledge to the new sensor in the EVA1. It is very high performance but the lessons learned make it less expensive to produce. Otherwise there would be no way for Panasonic to offer the EVA1 for less than $8000.

Panasonic will not be "holding anything back" in the performance of Dual Native ISO on the EVA1. The engineers have already hit certain target goals and continue to tweak the performance in order to get the most out the sensitivity without affecting noise, color response, dynamic range or any other performance characteristic. We'll give you all she's got.

On a related side note, unlike most other cameras the VariCams employ no noise reduction. Zero.

BTW, I for one have no problem with EVA1 posts in the VariCam area. At least until EVA1 gets her own space.

Its a good point to bring up now though. Where does EVA1 belong in the forum? We try to keep main forum sub headings to a minimum as the front page list would be huge. I know EVA1 isn't Varicam, but would a sub heading in Varicam suffice? With colours etc matched to Varicam look plus dual ISO, seems like once released (my hope moreover)it will actually turn out to be like the varicams sibling.

FWIW the sub heading under Panasonic could be changed to Varicams plus EVA1 so its clear. Another thought - Varicam people could be inundated here as I think the EVA1 is going to be very popular and user numbers will far outweigh us Varicam folk.

Thoughts?

Dual ISO Speculation? Sorry I got nothing. I know what Id like to see.
 
I vote of a subheading of VariCams & EVA1. In other parts of the forum there are tags at the front of each thread heading that the thread starter must address, noting C300, FS7 or the like. I don't know if that's completely necessary, but I could see this being split between VariCam & EVA1. I question if we need to break out the different VariCam models.

This is very encouraging to hear. Thank you.

Can't believe it wasn't mentioned earlier. I guess when you know you sometimes don't realise folks don't. There is a NR switch you can utilise and TBH Ive never used it. I've never add NR in post either. I should do a test on it to see how well it's implemented, seems a bit slack that Ive never looked into it on a camera I own even though previous camera experience tells me not to use it. Could be a great implementation for all I know.

Mitch, any hint as to whether we can expect the same (lack of NR) from EVA1?

In addition to the beautiful color of the Varicams, it seems that the lovely sharpness and yet softness of the Varicam image must be due, in part, to the lack of noise reduction and sharpening processing. I'm hoping for the same performance in that respect with the EVA1... even if the Dual ISO is not as high.
