Panasonic GH5 - all is revealed!

I'm hoping there are some settings he didn't have right for this test, because the AF performance here is pretty disappointing :(
 

 

Also a bit concerned that the camera will not fit correctly on the Zhiyun Crane (he mentioned it a bit earlier in the video). Still usable, but not ideal.

Yeah, at first, I was lukewarm, then hyped with some of the footage, and now it's a no go with that ghosting.

Yes, it's there. But have you ever spotted ghosting in any of the real world low light tests completed so far?

I've seen ghosting when freeze framing some footage (the low light V-Log stuff from Emmanuel Pampuri) - but it's not noticeable to me during playback from what I've seen so far. And ghosting is something that really bugs me, having wrestled with it extensively on the XC10. Even in this video, which is the classic wave-the-camera-around-to-show-ghosting, you have to kind of concentrate to spot it.

Jesus. Ghosting & bad CAF... I'm never going to buy any camera at this rate ;) I'm kinda kidding, kinda not. I admit I get wrapped up in specs and issues. it leads to paralysis and then angst. I either need to buy something, shoot and forget about it, or go see a therapist.

Funny thing is bought the SmallRig cage for 50% off despite not ordering a GH5.

Very odd. I got my GH5 yesterday, and as usually happens whenever I get a new camera, it rained. So all my testing was indoors, as I went through the house with lights off and on, testing AF with a 14-140 lens. When the lights were off, it was fairly dark given the weather we had been having. I experienced nothing like what he did with the AF.

I'm surprised he never tried a central zone for his AF mode as I did in my tests. Most often I was testing objects and not faces since my wife wasn't home, but I still would have used a center zone if I was only doing faces. I learned from my G85 that that's often more reliable than face tracking. 

I found the AF to be much improved over my G85 as well as my RX10iii and in the same ballpark as my now sold A6300.

On another unrelated note, I watched his entire video and was trying to figure out why his split screen tests with the tele extender mode (as it was labeled) was less zoomed than the side without it. Unless I'm misinterpreting what he did, it looked to be mislabeled.

This seems better than Max's test but still slow.

He said just what I did, center area is better than face tracking. I'm surprised Max didn't try that. As you can see in this test, he never had outright failures like Max had and nor did I. I think the AF is just fine. As with any camera I've owned, there's a time for AF, a time for AF lock and a time for MF. The GH5 gives you a lot of tools for AF, you just need to learn them.

Think about the scene in Jaws where they do a dolly out - zoom in. That would look entirely different if you were dollying out while digitally scaling the image.

Wrong. It would look actually 100% the same (excluding the resolution difference as you scale).

As you can see, there is no difference in "look".

That is a pretty good way to replicate it but it's not the same. Even the author admits such. A 24mm lens is a 24mm lens. A 50mm lens is a 50mm lens.

This is much better. Not perfect. But definitely usable. 
The results of AF tests I've seen seem all over the place. Some of them suggest it is terrible, and others seem pretty good.. I wonder what's going on.

I suspect, in most cases, it's simply people using the wrong AF mode or settings. But yeah, no AF, in any camera, is perfect.

Yes this is pretty much what I am seeing. But having tested it indoors in the evening I can tell you that with footage involving people it's even worse in V-Log. And it's not only the ghosting. There is some sort of strange banding and other artifacts going on.

I watched two previous low light V-Log tests and I could not see the same ghosting that I am seeing in my production camera. It's either a firmware change, or it's the fact that there is not much panning in the test videos.

I don't want to derail the discussion about the GH5, but I hate seeing bad information out in the world, and just have to correct this.

For all intents and purposes, as long as the focal plane of the camera is in an identical place in the world between shots with different focal lengths, the effect is mathematically identical to a crop from a larger FOV to a smaller one.  In other words you can animate a crop on an image to recreate the effect of a zoom with a lens.

The only things that could possibly be different would be characteristics of the different lenses, such as pin cushion or barrel distortion throughout the zoom.  Of course there are going to be varying resolving differences depending on the technique used.  For example a digital zoom is going to reduce pixel resolution,  but an optical zoom is going to be affected by any resolving differences of the lens at different focal lengths.   That said, if you took a theoretically "perfect pinhole lens" and performed a zoom it would be identical to to a crop on an image with infinite resolution.

I've run into so many photographers who don't get this, but I think it's an important bit of information to keep in the back of your head while out shooting--  you can crop in on an image and  it will have the same basic effect as putting a longer lens on your camera.  What's neat about the GH5 is that trick doesn't seem to have much effect on the detail in the image, so it really effectively gives you two lenses which is very cool.

Just as a side note, that Jaws effect is achieved by combining a move through the environment combined with a zoom or crop in to keep the subject in the same scale in the frame.  The key to the effect is that the camera is moving and not in the same spot from the beginning to the end of the shot, so you are getting the parallax of moving the camera.  In fact even before digital, they used to do the effect using optical printers in the same way in which we can crop a shot today.

I feel badly for people who are torn between this or any other camera for that matter based firstly on seeing great footage and then bad footage...if this is your criteria, then no film would have ever been shot on an Alexa...my advice to @Herbert Massey would be wait for Andrew's footage/review...he knows what he's doing, will give an unvarnished viewpoint of the camera and then you can make an objective decision re wanting one or not...this thread is becoming like a typical disaster movie where all the  hysterical victims are heading for the exits first, only die off before anyone else in the subsequent stampede lol...
