You're right...they don't have the same sensor. The GH-1/2's sensor is actually slightly bigger. The AF is an overall better camera hands down but when it comes to IQ the image on the GH-2 (unhacked) was always better looking. I was excited about the AF when it came out. But image wise...like someone already suggested...why didn't Panasonic put the GH-2's sensor in the AF100.

problem, is AF isnt hacked by DRIFTWOOD!!!!

Why not wait for AF200? 2012?

If one can make good money off GH2 shooting, he could award himself with AF200 or something... I guess. Still cheaper than M3 beamer :)

Anyone watch the Youtube video I posted? I don't see any mud in that video, and it looks unbelievable. Raw Af100 ungraded footage with albeit high end glass.

Time is to early really. Especially considering how far the GH2 has come to draw any sort of comparison.
I agree with VK here- these topics just create angry discussions.

@Shield: I agree. There are some things with that camera I love... And I actually like the picture of it, there's just something of it that's clean. But I'm myself is a GH2 owner and I don't know what camera I might get next. If I get one now that is...

But on to the AF100. Here's a music video I DP'd. We used both an AF100 for the majority of the video, a 5D on the scenes in the car and my GH2 for the shot of the car driving at 0:40 and the tunnel lights. What I wanted to show was that they all work very well together, but also that the AF100 can look amazing depending on what you put infront! We used mostly Canon L lenses and all the close-ups is a Zeiss ZF 50, all lenses which really brought out the camera. For example, compare to the ultra-wide shot of the guy shooting, done with the 7-14 which looks a lot more "video-y" I feel (but still good) compared to the 5D's wide-angle.

Sorry, forgot to post the video link (watch in 1080p!)

You just cannot compare the Gh2 to the AF100. I have owned both, and I just sold both my GH2's (and yes, I tried all different hacks on the GH2).

For starters, even in manual video mode on the GH2, I cannot adjust either ISO nor white balance while recording. This matters a great deal - lighting conditions change. No matter what on the GH2, tweaking the custom WB, adjusting Kelvin, trying extensively all the film modes, the color was just not right. The AF-100 has a dedicated autoWB mode, a physical WB button that if depressed also sets the black balance!

The Af100 has a shutter you can set so it's always using the 180 degree shutter rule.

The AF100 has "focus peaking" which tremendously assists manual focusing mode - whatever is in focus is highlighted in red, and it works while recording (not just before you hit the button like in the Sony NEX-5N). Gh2 does not have this.

There are exposure meters on screen. When it's too dark, there are bars on the left; overexposed it's on the right.
I can mount ANY lens with adapters without taking a hacksaw to them first.
I can adjust audio input levels for each input channel whether I'm using the built in 384k audio or the XLR inputs on the fly. This a BIG deal.
Dual SDHC/SXDC card slots.
Stock battery lasts over 4 hours.
PUSH AUTO FOCUS! I can't believe you AF100 users aren't talking about this. While in MF mode I can push a button QUIETLY and refocus. I have to go "clickity-clack" on the GH2 and toggle back to AFC/AFS to do this on the GH2.
Nice big quiet IRIS wheel in the front, instead of a noisy click wheel that you'll hear back in the recording.
At the end of the day I found I was never happy with the colors/white balance with the GH2. There was something wrong with all of them to a certain degree. This has been resolved with the Af100.
The AF100 does have face tracking for lenses that support auto-focus. It does work.
Form factor is better in many situations and worse when you're trying to be discrete; I will give that either way to the Gh2.

Watch this video in 1080p mode and you'll see what the Af100 is capable of.

By the way, I bought a very low use (14 hours) AF100 with an extra battery and all original boxes and documentation for $3400. So the prices have come down somewhat, and I've found that I really just love shooting with the Af100. It's a considerable upgrade in every way to the GH2 with the exception of no more ETC mode and the size. That's it.

I give Pany credit for even putting the AF100 together as quickly as they did. I just don't think they went all the way in on the AF100. It's almost as if they thought they could pull a fast one on dumb DSLR converts or something. As if we wouldn't notice the flaws. The noise levels and the inability to handle highlights. I really don't understand that kind of thinking. It's like didn't you use your own camera before you sent it out? Don't they have some trusted professionals they could give the cams to in order to test them and get real feedback? At $5,000.00 we have every right to expect a little better than they did. It didn't have to be a RED or Alexa, but surely they could've done better.

It's Ok to hack together all of the extra items needed to match the AF100 as most DSLR users do, but some just want the simplicity and quality of the AF100's included features and I can understand that. The price difference isn't as great once you start to add in a quality ND and XLR Mic Pres. The built in overcrank/undercrank is a nice touch and having clean HDMI output at 4:2:2 and timecode are important features for many users. AF100 also has dual SDXC slots with relay record for extended recording and programmable dedicated buttons for quicker setting changes. All of those additional things in one package makes it more acceptable at a price that's gonna be about $2,700.00 more than a GH2 after adding some of the gear needed to add some of the features of the AF100 and still the AF100 would have functions that the GH2 won't have. It's just a different tool!!!

Most of the tests I've seen AF100 v. GH2 unhacked give a slight edge to the GH2. If someone has some tests showing the opposite, love to see it. I think even Barry Green has stopped shilling for the AF. Lost cause.
