You guys could have done homework and simply asked Panasonic.

First, does it make sense for their flagship feat to look worse? No.

Second of all, there are actually ISO tests with 10-bit 422 in which the 10-bit 422 footage looks exactly like the 8-bit did in this test.

So from that, the first thing you should ask is if this is because it's pre-production and then, just ask them.

I asked Sean Robinson and he said that there is no difference in ISO performance between 8-bit and 10-bit, so most likely this is simply due to pre-production FW in some cameras. So in some cameras NR is probably completely turned off in 10-bit, and as we know, no manufacturer release a camera like this with NR turned off, you can dial up or down, but never turn it off.

Man, I've never seen such weird coverage about a camera that hasn't been launched yet. I bet next time Panasonic will hand no pre-production camera over nobody since people don't quite understand what pre-production means.

"Yes, we probably shot 20% of our video in 4K/60p. It looks good, not 10bit good, but GH4 8bit good."

In what sense?

For the most part, nobody can tell a difference between a 8-bit and 10-bit file by simply looking at it. When you evaluate an image, even more a faster framerate one, you usually look for image details and some other things, maybe compression artifacts, nobody says this looks "8-bit" or "10-bit".

What does "not 10-bit good, but GH4 8bit good" means? In terms of color grading? In terms of color grading, an 8-bit 420 4K60p grading similarly to the GH4 makes sense, but otherwise it doesn't make much sense to me or maybe just a poor choice of words.

The next one should be exactly the GH4's sensor since the specs matches, the difference is that it should have RAW, so it can be better. DJI used the specs from GH4's stills instead of video, that's why in theory the specs looks better when it comes to DR, but not that it will encessarily translate into reality. Anyway, the least you can expect is the same quality as a GH4.

How much complain, huh? A lot of the people complaining seem to have delusional expectations, taking the camera out of context, treating this like a FS7 successor instead of a Canon C100 MII competitor.

This camera is for those that want a small and light camera that can work well out of the box without the need of a lot of rigs, one that can do great 10-bit 422 HD video but also gives you the option for short 240fps with the same 10-bit 422 output. It also comes with 4K, it's 8-bit 420 and a Long GOP codec but treat it as an extra because that's what it is. It's for those situation in which you want extra room for crop or stabilization in post - plus keeping a small sized file. It's not for heavy post production, color correction, chroma key, etc. It's an extra or for those that don't need that much.

If you truly want 4K you can either wait for the 4K RAW firmware for external recording or simply buy a FS7! Don't be delusional, you won't be getting FS7 feats for FS5's price tag and compact size.

You can also go for Black Magic's URSA Mini but it has a bit different purpose compared to the FS5, although the body is priced similarly to the FS5, if you buy all the needed components like viewfinder, battery, etc., it will get well above the FS5, so it's not really a direct competitor. But it's still an excellent cost-benefit considering the excellent quality, but that's a different beast I would say, completely different workflow, you will need a bigger infra structure, much more storage, etc. - plus you will have less lens mount flexibility.

So again, this is a C100 competitor and that's how it should be treated when posting some constructive criticism - but I know, this is the Internet, what was I expecting?

Some people would had wanted the IBIS the A7 family has, which works fine when you are holding it still but it's not reliable for movements, so you better off with a gimbal.

My main issue about this FS5 is the base ISO 3200 for S-log. Sure it has the electronic ND filter up to ND128 but in a sunny day that will not be enough, it's like you have a camera with ISO 100 plus a ND4, it would be more useful to have a lower base ISO or a darker ND, but at least it means the camera won't get in the way. When I read manual ND I had hopes it would mean an extra ND but by the side layout you got to choose either Preset or Variable, so it probably means you can have either but not both - can someone confirm this?

Overall this seems to be a great camera for what it really is.
