The lens remains rectilinear (straight lines) even at the widest setting, and combined with a focal reducer you're actually faster than an F/2.8 (which is better for dim lighting). I believe if I upgrade to a more recent Metabones XL Adapter, i'll get sharper results. But it's pretty darn good as is.
For moving the camera, i'm testing out the CAME-TV Prophet Gimbal which is designed to fly heavier camera setups. The combination of speedbooster and Canon EF type Lens may be a bit heavy for the smaller Optimus gimbal.
Here's a quick sample shot with the new Panasonic GH5 Camera using 48fps in VFR (variable frame rate) shot with the CAME-TV Prophet Gimbal and using the PVGear ND Filter Adapter with the Panasonic 7-14mm Lens. The ND Filter allows me to keep my shutter speed in control on bright days. I shot this using the 'Natural' profile in the GH5 at 4K 8bit. I later adjusted the color and exposure using just the basic FCPX Color Board.
Considering the low bitrate of internal 4K 8bit recording, I think the samples clip above held up really well pushing around the exposure and color. I can only imagine how much better the quality will be when the new Firmware with high bitrate 10bit drops this summer. The colors of the GH5 is much different than the GH4 camera, which always had a shift to orange/reds. It feels closer to Canon color science. The dynamic range seems to have improved and it's far better in low light and cleaner at high iso when compared to the previous GH4 camera, but still not as good as sony in low light conditions.
Experimenting with different color profiles found in the new Panasonic GH5 Camera before I run out to shoot this weekend while traveling. I'm just looking for a flat profile that could offer the most latitude without adding too much noise. I think what's helpful in this video is the waveforms and vectorscope showing how the different profiles affect exposure and saturation.
I proudly own (3) Panasonic GH4 cameras, and it's just been a dream working with them. But the new Panasonic GH5 advancements is leaps and bounds above the GH4 and I think it's time for the upgrade. No limit time recording, Higher ISO recording, in camera Image Stabilization, 4:2:2 10 bit recording, 4K up to 60fps, VFR up to 180fps, Dual SD Card Slots, increased resolution (no crop in 4K), Full Size Type A HDMI input, almost 5x more focus points, new external Dual XLR Mic Adapter, and a firmware update later this year for 6K Anamorphic support, Hybrid LOG profile, to add up to 400mbs 10bit All-I internal video recording which is just mind blowing.
Upgraded, redesigned, and filled with features, the Lumix DC-GH5 Mirrorless Micro Four Thirds Digital Camera from Panasonic provides an outstanding imaging platform for shooters who demand some of the best video and still photography quality they can get in a single compact camera.
At the heart of the new Panasonic GH5 Camera is a 20.3MP Digital Live MOS sensor and a newly developed Venus Engine processor, which both offer dramatically improved processing times over its predecessor. This enables the ability to record 4K video at up to 60 fps, 10-bit 4:2:2 internal recording with select settings, Full HD video at up to 180 fps, 12 fps continuous shooting, and sensitivities up to ISO 25600.
Also, the camera features built-in 5-axis sensor stabilization, which can work with certain lenses to activate Dual I.S. 2 for highly effective shake correction that can compensate for up to 5 stops of shutter speed. Other improvements include a speedier and more accurate Advanced DFD autofocus system that can lock on in just 0.05 seconds, as well as 6K PHOTO at 30 fps and 4K PHOTO at up to 60 fps.
