GH5 How to match GH5 natural with GH4 natural?

[CustomerGH4]

I seem to get different images even though I have both cameras on natural and same settigns, could it be that one camera uses a different lens that the colors are not exactly same? The lenses I use are 12mm Rokinon and Leica 25mm.

Without a doubt. Different lenses even from the same manufacturer can have a color tint. The Rokinon vs Leica which I also both own have a very different color look to them. Both lenses will also have very different sharpness and contrast. The Leica is an electronic lens which gets a small amount of correction in the body of the camera. The Rokinon is full manual and gets none of that correction or enhancement. If shooting a -5 sharpness with the Lecia I tend to find a -3 with the Rokinon to b a better match in terms of sharpness. You will have to explore different settings with both lenses to see what works best for you for a match.

Keep in mind the GH5 and GH4 handle detail differently and a -5 sharpness on one will not be the same as -5 on the other. You will have to explore which settings create the right balance for you.

I think you also have to add that the in-camera color has changed on the GH5 relative to the GH4. So it's not hard to imagine the camera's color itself has changed despite using the same 'Natural' profile.

The other thing to remember is that it is a different sensor that has no AA filter. Add to that a new processing engine, and I found early on that simply copying GH4 settings doesn't give me the image I thought it would. You have to start from scratch. However I still use Natural, or V-Log L.

Color science is materially different on the GH5. The new debayering allows for colors (in video and jpegs) that weren't possible on the GH4. This is really noticeable with certain colors, like warm blues leaning into violet. Other colors, like skin tones, are more subtly improved.

Matching the two cameras can actually be challenging. Depending on the scene, the necessary compromises may be noticeable. As I have 2 GH4's that will continue to serve as B cams, I'll probably end-up making a lUT to ease this effort. If I do, I'll post it here.

I'd be very interested in such a LUT if it helps get the job done quickly. Happy to donate a bit for your time too. I do a lot multi-cam event shoots with my gh4 now being turned into the locked down cams and GH5 the roving cam.

In addition to the new color science or whatever you want to call it, there is a difference in how the GH5 white balances. If you happen to be using AWB, try the AWBc and see if it doesn't tone down the reds and the slight violet shift toward canon colors AWB is giving. I haven't been able to see much in the screen, but there is a difference in how it presents white balance between those two settings.
