These are my observations after using the camera for a few weeks.

First, I found that operating the nonprotruding video actuation button was not optimal and ended up adding a $10 Vello 2 ft wired remote. This also allows use of very slow shutter speeds and facilitates macro imaging, and I use it for interviews so that I can stay where I’m interacting with the subject- the same as I already do with my H6 Zoom audio recorder.

With a 64GB U3 rated card I’m getting more than 80 minutes per clip at 4K resolution. No more interruptions to reset the camera for interviews…..

Second, after renting the 18-35mm f/1.8 EF Sigma I think this lens will be excellent for general use especially on a rig with follow focus, but too large and heavy for backpacking and [currently] doesn’t support AF; so I will most likely buy the Panasonic 12-35 f/2.8 and 35-100 f/2.8 eventually, and continue to rent this optic.

Third, I’ve settled on Custom settings for the main 3 dial positions= C1 for 4K DCI/24 ‘Cinematic’, C2 for 4K UHD/30 ‘Broadcast’, and C3-1/ C3-2/C3-3 for ‘highest quality ‘ 1080/60 moderate slow motion, ‘smoothest’ 1080/96 slow motion, and 1080/12 undercranked fast motion. NOTE: this camera allows 1080p in slow-motion 96 FPS whether in 30 or 24 cinema modes.

Fourth, as a walkaround lens I ‘m using the Pana/Zeiss Summicron 15mm f/1.7 – a tiny, ultralight lens simulating 30mm perspective in full frame terms. Sharp, easy to maintain relatively great DOF (nice for rapid event action), beautifully integrated with the camera’s capability, easy to carry long distances, and wide without distortion.

Fifth, the Metabones EF to MFT Speedbooster will be a keeper for me as I have 2 Canon FF lenses and it opens the entire Cine and still collection to the camera, as well as lenses from Rokinon /Zeiss/ Olympus/Voigtlander in particular. The ‘free’ additional stop from the adapter has been very welcome in keeping the ISO settings in the optimal range. I find that linking the baseplate/rail system onto the removable Metabones tripod mount provides the clearance I need for attaching the Rokinon 14mm T3.1 and 35mm T1.5 lenses, which have large front elements.

An added bonus is that as long as the adapter is attached, the camera sensor is completely shielded from damage while changing lenses.

Sixth, I’ve evolved a minirig for ENG and light EFP use consisting of an aluminum form-fitting cage, JAG 35 top handle/tripod base plate,carbon fiber 15mm rods, and RedRock Micro spuds/attachment points.

I will be using a $12 basic Nikon F to MFT adapter for AI-S Nikkors for the immediate future, and rent the F/G to MFT Speedbooster when needed.
