So I played with the GH4 this afternoon at Jessops, Oxford Street, London. Although I spent around an hour with the camera, I was not allowed to record any footage to my SD card as the Panasonic rep said that the unit was a pre-production model without the release firmware. Being a nice chap, he did allow me to test many of the video functions and looked closely at the 2 Cinelike profiles the camera has, Cinelike D and Cinelike V.
I've never held a GH series camera in my hand before, so I was very suprised by the light weight of it. I'm used to the weight of my 5D MKIII with lump of L glass, so it was lovely to hold a camera that felt so nice in my hand. The OLED screen was very sharp and clear and worked perfectly to pull focus. The EVF was bright and full of detail. The eye piece was ultra comfortable. Focus peaking worked an absolute treat. A quick word about the autofocusing, its very impressive and I noticed no 'hunting'. I think it will be pefect for shooting with the 96fps function when you want to track something that is moving at speed.
The Cinelike profiles look interesting and I believe no footage we've seen so far has used these profiles to capture footage. Cinelike D is pretty much like a Technicolour style flat profile which is probably going to be the most used one on the GH4. Cinelike V seems to crush all the shadows into black and I found it hard to see what purpose this profile would serve.
The DR of the GH4 looks really good. Even though we were inside near the back of the store, when shooting out towards the windows, plenty of detail was retained outside. I know on my 5D, lots of it would have been blown out, almost white!
Unfortunately, I was not able to look for moire or aliasing as we could not connect the GH4 to a monitor and it was too hard to notice it on the OLED or EVF as they are too small.
In all, its a great camera and I can't wait to see more footage from it in the coming weeks. I did get the Panasonic rep to watch my showreel and while winking at him said I've love to shoot something for them :)
If you have any Q's please feel free to ask. Finally, some photos of the Cinelike profiles, this is the best I could do :(
