Yeah, nice clip but I am not impressed by the stability. Very shaky. But it's one clip, not a video.

GH4+Nocticron 4K Video

Here's a short video shot with the GH4 and the Nocticron as one would normally shoot a video, in shutter-priority mode (1/60th for 4K 30p). It was shot at dusk and with an .8 ND filter to open the aperture. Handheld to test the OIS using my best technique (viewfinder), and close-ups to test the bokeh. I used autofocus, and you will see why you want to focus lock (which I normally do) after autofocusing.

Some video frame grabs:











Of course, the Nocticron is an ideal portrait lens. But I do not know anyone who wants to have their face posted on the internet, for free.

The Leica Nocticron Lens Belongs in a Museum

In museums light is the enemy of artifacts, so they are dark. Perfect for a fast f1.2 lens. Handheld to test the OIS. Close-ups to test the bokeh and focus.
Dinosaurs, dioramas, lizards, lectures, gemstones, mummies, and even a ghost. Plus a trip to the museum store.
Shutter-priority at 1/60th.

Handheld shooting does not work well for the GH4 - there is constant horizontal - only! - shake in all the shots.

There is some noise in the mid-tones on GH4 4K, but applying a little temporal denoising using the Neat Video plugin on these clips removes this for a totally clean image.

I also tried a bit of sharpening on jogiba's clip, but to my eyes this produced an unnatural-looking result - it is sharp enough as it is.
