I'v been asked by the BBC to produce some video resolution tests for the Panasonic GH5 to be included in the list of approved cameras. Ideally on the TE125 chart or similar. I can order a test chart, but that's going to take a few weeks from Image Engineering in Germany. Does anyone else know where I could get the chart or who I might contact to get the test performed? I'm in the UK and any help would be appreciated.
