@AdamT thanks, I know, but if you shoot watching through the viewfinder, it will be useful to control audio directly with one of the two rings

@gameroja @CFreak - I actually prefer that the camera does not over-write my Custom (C1, C2, C3-1,2,3) settings unless I explicitly over-write the setting. It's very convenient (for me) to know that whenever I engage a Custom value, I'll be starting from a known settings and I can anticipate what exposure/setting changes I'll need to make when I decide to switch to a given Custom setting. For example, I use my C3 settings for my favorite quick outdoor video starting points (4k30p, 1080p60-100mbps and 1080p30-96fps, all with 180d shutter setting). It's handy that the Menu/Set button will default to the C3-1,2,3 selections.

@Josh, I was wondering what that 100% sing on the top of the screen was, and discovered that it was relating to the VFR so it shows up when you turn VFR on.

I had problems connecting Roede Stero Microphone to GH4. The levels were extreamly low. The mic worked very well on my GH2. I have now tested different homebiult converter cabels between TRS and TRRS plug. My finding is that the GH4 is using left channel to the tip, right to ring 1 and ground connected to ring 2. I left the sleve open. The levels are still lower than the levels from the internal mics but much higher than before. I have not tested the sund issue yet.

@brant_moore: That´s more or less based on the technology - LCD has way less contrast (and through the backlight the image always seems flatter / the dark areas always are more "geyish"). Just compare the image on a good external screen, to see which one is more accurate (the EVF or the LCD). But in general I think that you can trust more the LCD screen than the EVF (as most OLED screens I saw til now were not the most accurate ones ^^).

GH2 didn't have an OLED EVF.

Just got my GH4 so am in process of checking it out.

First issues that are mostly post and little stuff.

1. No way of getting raw pictures into Photoshop or LIghtroom. I'm 1 rev back on both. Work around seems to be only for current versions of light room & photoshop unless I'm reading it wrong. I do not need the new versions and would rather spend money on lens.
2. Windows media player won't playback 4k .Mov files. Needs a new codec. If QT pro is the answer, that doesn't fly with me cause I have 3 computers and not spending the money on software which is free for most peeps.
3. Vegas v12 shows the correct clip length for audio, but hold last frame in video for many more frames. On1 minute clip, video showed 2 minutes or so. Can trim the video back and it seems to work ok. Haven't output any edited material with sync so don't know how big a PIA it's going to be.
4. Premiere and Aftereffects seem ok with it.
5. Manual is long. Have lots more stuff to go through and learn.

Good things.
So far both my 64gb sandisk cards (95/MB/s and 80MB/s ) seem to record 4k although I haven't done a torture test or long capture beyond a few minutes. Video looks pretty good, but I haven't done anything of to show off yet. Still in first few hours of going through menu's .

Got lots of tests to do. Same size of GH3 so I can put this bad boy up in the air on my multirotor.

I have that on one machine and was going to try it. Had read it didn't work. But thank you, it does work. Also found a beta version of DNG convert from adobe that converts the raw files to DNG.
2 irritations out of the way.

@jfro

The stand-alone Adobe DNG converter is always "free" ... and is quite often about the first thing one can do to utilize new cameras in Adobe & other RAW processors. Just update the stand-alone every time you need it for a new camera ...

I've encountered an intermittent problem the last few days. Thick horizontal bands show up in the captured images and video. During lcd/ monitor preview, these bands (about 4-5 total at any one time) slowly move upwards - not unlike the scan lines that appear when recording a computer screen that's not in sync with the system frequency.

This problem worsens as shutter speed is faster. At low shutter speeds during video recording it is not noticeable. Yesterday this issue sprung up, even after a power down. Then about an hour later it was back to normal. Same thing happened today while taking photos, then after about 30 minutes back to normal. Nothing in the settings changes anything.

Any ideas on what could be happening? It's like there's a loose connection somewhere screwing things up. I will probably send it to Panny for repair I just wish I could duplicate this problem on demand.

Hmmm - today there were HID lamps, so definitely could be. Attached is an example. Now that I think of it, both episodes occurred indoors. Just bizarre that I encountered the same problem in 2 different states actually, after never experiencing this since I owned GH3/4

This is a good application for the new synchro scan feature.

@CFreak yes USA

I thought synchro scan was for video??? The banding I experienced was much more obvious at faster shutter speeds 1/1000+

At slow video shutter speed I did not experience the same problem. Intelligent auto mode also did not show the banding because it would select a slow shutter by default.
