Yes - 10 bit output disables internal recording - so that's certainly an issue to be aware of. 

Like others have said, I think you'll get more with a camcorder for that price. I don't understand why you need a dslr. I don't think what you'll get from a dslr for that price will suffice for a video camera.

A lot of people are viewing the GH4 4K material on 2.5K or 1080p displays and there's crude downscaling going on which results in an over-sharp image and even some heavy aliasing. A lot of the YouTube stuff looks thin and sharp because of compression and bad downscaling.
  First time I graded the GH4 files I was pretty happy and yet we've only realised half the camera's potential so far. Once we get the Atomos Shogun we will be getting uncompressed 10bit 4:2:2 4K out of the HDMI port. DXOMark tested the raw output GX7's sensor (similar to the one in the GH4) and it rates for about 11.8 stops dynamic range, pretty much identical to the 5D Mark III.
 
The GH2 and 5D2 have been around for ages and the GH4 is a far bigger step up from the GH2 than the 5D3 is from the Mk II.
 
Michael - ignorance of the reason other people choose to shoot with the GH4 does not make a good debate. Also remember that the filmmaking world is small and you are using your real name on the forum, if you piss someone off, eventually it will come back round. There's no career advantage to behaving like a complete prat in front of half the digital filmmaking community.

Hello Everyone!
 
I'm a huge fan of this forum and I'd really like what Andrew has done for the Indie Filmmaking community. Anyway, here is a video I'd like to share with you all about my trip to Yosemite with the GH4. It was raining, snowing, and sunny in one weekend so I was very fortunate to catch all of those elements in such a short span of time!
 
As for the GH4, it was completely drenched in rain and snow and it still survived! I absolutely love this camera and I found it to be much more practical and enjoyable to shoot on than my BMCC and Pocket Cinema Camera. I can't wait to post my video review on this camera. I'll be comparing this to the 5D Mk. III Raw, BMCC, and Pocket Cinema Camera.
 
I hope you enjoy the video as much as I enjoyed making it, and any questions and feedback is welcomed! Thanks!
 

And I think Daniel is talking about a 50mm and 85mm equivalent. Your 25mm should be fine for portraits but I would second the zoom lens. ND is essential. Try and use it for everything outside instead of increasing shutter speed. Your shutter speed should stay approximately double your frame rate. So if you shoot 24p then shutter at 1/50.
 
Also, I don't see why you need three shoulder rigs, especially if you value traveling light. Personally I would just stick to your pocket rig and maybe think about something like a Zacuto Z-Finder Jr instead of that dot-line. But yeah, I would say prioritize a zoom lens above all. A kit 14-140 is relatively inexpensive, especially the old f4-5.8 version. It's not the best piece of glass in the world but I think you'll appreciate the versatility. Just stick to the 25mm inside.
 
And yeah if money is a concern I would put the lens above the go pro but that's just me.

Alas, a good ol' uninstall and reinstall seems to have done the trick. Runs surprisingly well now actually. Knock on wood...
