We completed a series of interviews with local officials in Visalia, CA and talked with local resident Donna Johnson in East Porterville about what she was personally doing to help neighbors whose wells had gone dry (as was her own).

The level of poverty in East Porterville is intense. Housing prices, already low, are decreasing due to lack of water further burdening residents who might want to leave the area.

We shot with my Panasonic GH4 in 4K 30fps mode, using a Zoom H6 digital audio recorder as well as Audio Technica Pro70 wired lav’s an dRode NTG-4 shotgun in a Rode blimp.Also used a Zoom hypercardioid shotgun mic and when using the Zoom for field notes, the mid-side capsule mic. I was very pleased with the performance of my equipment in very hot conditions, wind and for interior shots with no problems encountered.

There is still much to be done before we begin cutting the documentary’s final look; a tentative title: WATER AND THE LIVES OF THOSE LESS FORTUNATE.

The Zoom H6 digital audio recorder is powered from the accessory USB port on the battery, shown above.

It’s a good idea to not allow these batteries to be uncharged for long periods because of their self-discharge property; I mark them each time they’re charged, and aim at less than 6 months before recharging.

And double check to ensure that the terminals of the P-tap connector are properly aligned to the corresponding terminals of the battery plate- if not, there’s risk of short-circuiting the cable (I’ve done it – ONCE).

First followup review of Panasonic GH4 DSLM camera

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.
