@caveport - on the GH4 you can enable Syncro scan when using VFR so would assume you could just as well on the GH5 (another example of why Panasonic needs to get the GH5 in the hands of people who know what they're doing to avoid terrible footage like this!)- My C2 setting on my GH4 has synchro-scan enabled w/ shutter at 1/119.99 sec (closest I can get to 1/120) and 1080 96fps conforming to 23.98p 1080 since I am based in US and our flicker is on a 60Hz cycle - which is kind of beauty with 180 FPS in North America, you should be able to use a 1/180 shutter if needed for most light possible when shooting at 180fps and as a factor of 60, should cancel out most if not all flicker. Rest of world could do same with 150fps (1/150 sec shutter) with 50Hz electricity - or just bump shutter to 1/200.

cos for my understanding we dont need so much back prossesing at 480fps. so why so much noise then, i dont undestand why so many improvements but no DR from that sensor, well capaciti can be improved by lowering resolution.

Minimum resolution they could have is 4K, but as 90% of buyers still shoot videos only from time to time it means big reduction in sales. Proper scaling actually is within few percent of lower native resolution.

We have FAQ item on this - http://www.personal-view.com/faqs/camera-usage/general-camera-usage-faq#more-megapixels-is-worse-isn-t

@endotoxic

My rant is about to much years for so little improvement in DR, come on!

Well, if you understand how sensors work, why you ask so much from sensor of same size?

The only was to rise DR in normal brightly lit situation is to lower noise as your well capacity is more or less fixed.

And in GH5 we have so much asked sensor stabilization, and it means thermal noise rise.

As we'll get GH5 we make sure to make thermal videos of sensor after long shooting session and compare it to GH4 and GH3.

@caveport Alexa now is a reference camera, so anyway all other cameras will compare with it. Already 4 years since we have cameras that twice cheaper than Gh5, and close to Alexa in terms of dr, color, organic motion feeling, it has size of smartphone and shoot RAW!!! - i mean bmpcc (and bmmcc). BM footage easily mixing with Alexa footage in many projects. Yes, Alexa is 1000 times better for real production, but bmpcc footage is much closer to Alexa than GH cams footage. So technicaly good DR, color and compression is not fantastic for gh5 price segment today (and yesterday) and may be it is only marketing reason to so slow evolution of this parameters in dslr or mirrorless photocameras. About gh line - it is very important to have progress in DR, it is more important than 4k60p (or 6k)))), a lot of commercial projects today still shooting on Alexa in 2k, because there are no any reason to shoot it in 4k (4k is great feature anyway). I think in 2017-2018 we will see small and cheap camera with 15 steps of dr and raw.

@endotoxic I really wish I understood your posts.

Most of what you say, such as "Bad highlight handling. Extreme contrast allways. Blacks with no data. Moire on some scenes." is just silly. You really can't evaluate a camera by looking at a few online videos. Then you follow up by saying "I you want a pro suggestion sell your g85 and buy the GH5. PERIOD. All is better."

So what do you really think? GH5 is good? Or not?

Comparing to an Alexa is not useful as the GH5 is not in the same category at all. Yes I know the Alexa is considered to be the benchmark for professional digital imaging ( I grade Alexa footage daily) but it's a different form factor and technology. No other camera maker comes close, which is why they are used for major cinema productions. No other compact or DSLR camera brand will compare well to Alexa either so your comparisons are pointless.

@brudney +1

I see something strange in this slow motion, can be the type of artificial light.

I think you should wait and see till the camera actually ships. Even if it were the exact same sensor it now is non cropped in 4K and has internal stabilization. Two great things to me the test will be if it does anything twice as good as my current G85 to justify the hefty price tag.

then i said: @Eno @Vitaliy_Kiselev

It seems they threw on all to the venus engine and only overclocked the sensor.

Ohh, now everyone likes the sensor?

Well i dont see any improvement just low light. For general purpose its ok, but selling 10 bit HDR ready with that dynamic range, seems stupid.

I thought this baby was capable of 13.5 stops, but seeing this, only low light is improved. Yes in that aspect for sensor size, is good noise reduction algorithm, cos with that back prossesing at 480fps makes good noise. Unless is REALLY ALL NEW SENSOR.

That sensor has several issues.

What kind of issues?

Bad highlight handling. Extreme contrast allways. Blacks with no data. Moire on some scenes.

All you listed is not sensor related (for specified sensor size, of course). It is in camera processing.

@JamesAllenVisual

I think no one told that it is free. It was good idea, but nope.
