Panasonic GH5 vs GH4 w/Speedbooster & Sigma 18-35mm

When Panasonic revealed the specs of the new Panasonic GH5, every indie filmmaker, including myself, were stoked. But how good is the GH5 in real life? Let's compare it against the GH4 in this quick video quality comparison.

In this video we compare:
- Low Light ISO
- Dynamic Range
- Crop
- Stabilisation
- Rolling shutter
- Slow motion
- Overall video quality

Ps. Looks like the internal Apple Prores recording in the GH5 was just a rumour. The text in this video is therefore wrong. It should be H.264 instead of prores :)

Since the 10bit in the GH5 won't give you better video quality than 8 bit (unless you do you heavy color grading) and as we didn't have much time to test the camera on location nor in post, we didn't include 10bit in this test.

To make the test as fair as possible, both cameras used a speedbooster together with the Sigma 18-35mm lens. We shot with the same settings and the same picture profile Cinelike D with -5 contrast (the rest was set to 0). I added the Filmconvert Pro LUT in post, without film grain.

We hope you like the video! Don't forget to subscribe for more filmmaking content! :)
