A simple test with high detail scenes.
Gh3
35-100mm Lumix
Heliopan Vari-ND
Shot 50mps 30p
All shots standard profile and settings listed on each shot in the video
No grading except last shot of old bench.
Also kept camera meter level at zero to see how the camera would choose to meter. Used average metering.
Some shots in here using the ETC (it's useable but has a super rolling shutter. ETC is good for locked off shots or a super slow pan).
