In this pair of videos (this is the HD version, there's a separate 4K version) Ted and I test three cameras:
A Panasonic GH4 with a Lumix 12-35 lens in UHD
A JVC with a Rokinon 35mm lens in M43 sensor size
A Panasonic GH4 with a Rokinon EF mount lens on a Speedbooster.

We test what the video looks like recorded as
- Rec 709 (Standard profile)
- CineD (Leeming Lut)the JVC has none so this is skipped.
- Log at ISO 400
- Log at ISO 800

The two log tests are:
for the GH4's the image is +1 stop. Many feel LOG is better when Exposed To The Right ETTR, or pushed.
for the JVC, it defaulted to ISO 800, so we stepped it down to ISO400 to match the exposure with the GH4's.
So we tested both.

Thanks go out to Ted Ramasola ramasolaproductions.com
for his assistance, watchful eyes, and second GH4 for the tests.

Thanks also to Paul Kepner of Cadillac Dreams Studios facebook.com/cadillacdreamsstudios for letting us use his space for the test.
