I can see that the GH3 pulls out a trace more detail in photos, but the question is which one has the best video?

So anyone here done video comparisons between the GH3 and GX7? Also, have it been proven that the GX7 doesn't have an AA filter?

@PauloTeixeira - I'm working on testing a GH3 and GX7 using the same lens, problem is the weather hasn't been good here for the last couple of weeks and I don't feel I've gotten the best results I could from either camera. I also don't have two of the same lens so can't test both cameras side by side at the exact same time which makes it a little harder to get really scientific results...if anyone wants to send me a matching lens I'd be glad to use it and send it back!

Once I have good samples to share I will post the original files for everyone to download, so you can come to your own conclusions on the two cameras.

PS. I hope the GX7 can be hacked!

Looking at the blunty vid there does not seem to be any difference in the video Q. Since the GH3 is cheaper maybe I will go with that one for the difference in the stills.

Finally got the GH3 vs GX7 testing done, you can access the test photos / videos through my site - http://www.matthewchase.com/panasonic-gh3-vs-gx7-photo-video-tests/

I posted all the original video files and RAW photos for you to download and compare. Please be aware though that my testing procedures were not scientifically accurate due to only have one copy of the lens I was testing with. I did my best to get everything the same.

@Matt, well the GX7 appears a lot better? using both 0-255, and 16-235, latter for GH3, the GX7 appears superior in every way? That is a shocker?

Camera has 1080/60p and 24p resolutions, with bit rates of up to 28Mbps, using the AVCHD codec (MPEG-4 is also available). You can adjust the shutter speed and/or aperture, as well as the mic level. Unlike many other mirrorless cameras, you can use focus peaking while you're recording a movie. The same 'tone curve' shadow/highlight adjustment tool is available, and you can apply the same special effects that are available for stills.

Bad news is that highly touted in-body stabilizer cannot be used while recording video. And, there's neither a microphone port nor a headphone socket.

GX7's photos have vivid color, with a sharpness level that's right in the middle, so you get plenty of detail, without artifacts. Panasonic takes a conservative approach to noise reduction, which means that photos will be a bit grainy at higher ISOs, but detail smudging is less of a problem than on its competitors.

Looks nice for video, but the panny lenses are really over-sharpened like before..

Check the built-in mics on the GX7?

Hi Matt, I am no pro either, but discovered no end of issues with replaying video clips accurately on PC's! I think you are probably getting a much better result on macs, as they appear to interpret the footage better? The reason I mentioned it was that the GX7 clips seemed good, both colour spaces but the GH3 appeared wrong as if it was being interpreted wrong with the usual 16-235 issue! In any event, I just think the GX7 look better, I will check on a retina MBP at some point to for interest. GX7 is one hell of a camera.

The video quality of Panasonic's Micro Four Thirds cameras has a reputation for being excellent, and the GX7 is no exception. It can record Full HD (1080p) video at up to 60p (as well as 30p and 24p), with an ISO sensitivity of 3200 (up from ISO 1600 on the GX1). In addition, full PASM exposures can be used while filming. Videos shot with the GX7 were sharp, smooth and pleasing, across the board.

Camera won over predecessor, the excellent Panasonic GX1, in terms of detail, dynamic range and high ISO performance, while also providing in-body sensor shift image stabilization. In addition, the GX7 steps up with Full HD video recording capability with frame rates up to 60p and stereo audio for shooting sharp, smooth movies.
