Only real reason I see is the mass of camera and lenses.
It also can be some difference in settings or auto mode, but I doubt that it is big.

@Mimirsan

Definitely Pixies with Fairies a close second.

Of course shooting hyperactive children @ 1/8th second had absolutely nothing to do with the OP's blurred images did it?

Man.. i didnt mean to make people mad because of my stupidity.. If you feel im an idiot, dont comment and move along.. Im just a guy trying to better myself.. Im sorry im not a Professional like all of you Geniuses, who hate on a newbie.. To the people who really want to help.. THANK YOU...

True i could have used Manual mode, but im doing it in iA mode, which is supposed to work for all situations.. I wanted to find a better solution to using iA, because my wife uses this camera to take pics of our kids.. Yeah i know faster shutter speeds, better glass, etc etc.. I did own a Nikon D300s and multiple F2.8 Lenses.. I know WTF im doing.. Maybe i should rephrase my question and see what comes out..

I want to know if anyone has better tricks to take pics of moving objects, in iA modes..

Anyways.. I wanna thank the people who really tried to help.. Stonebat and Driftwood were very nice in PM'in me about how to hack my camera and how to put in patches.. Thanks..

Everytime i've heard people say how awful the GH2 is with stills, i've usually found a way to take some nice pics with the 14-140. Its a viable option under 5D. GH3 will be amazing i'm sure. Agree with @John_Farragut. I think its just a familiarity with cam and basics.

Here was more an action shot and will probably make a poster of. GH2 came through. http://photos.jamesthorpe.com/Other/Cats/15525350_7JFdSt#!i=1879830428&k=gGMH2qf&lb=1&s=A

@WRLEO my guess is that you've still to sus out the camera and settings, and what works best for you with the lenses that you have. Like with every new camera it takes a while to get accustomed to it's features and quirks... There is not a wealth of info on GH2 stills out there like other cameras but maybe this blog http://docmatix.blogspot.co.uk/ can help you get started and achieve the results you are looking for, i found that it helped me somewhat when i got started with the GH2. Hope this helps. I also strated with the 14-140 coming from a canon background and it took me a while to adjust but now i've learnt the ins and outs of the camera and lens i love the results that are coming out of this little beast. I now have a bunch of legacy lenses and the results are on par with canon if not better IMHO. My advice to you is to stay away from the Ai mode. If your wife wants to learn the camera then set it to P and work from there. Good luck i'm sure you'll get it all figured out.

@thepalalias +1 good advice this is a great starting point

To everyone else with positive advice.. THANK YOU...

@Diffusion33 what legacy lenses have you found to be best? I was thinking about the 12-35mm Panasonic f2.8 lens.. Any good lenses for recommendation for video and or photography? Fixed lenses? Zeiss?

I really like GH2 at stills. I have long history with canon. And I am still photographer 25 years But last 19 I shooting video so much. But now I really don't want take 2 different bodies with different lenses if I need make some pro stills portraits. Yes, right choosins lenses for stills is required for make you satisfied. But now I bought also unexpensive still flash for M43 and now I bring less heavy equipment but more M43 lenses. I really impressed by ability Noktons analog and no AF lenses make sharp and artistic still photos.

the gh2 with the 14-140 is the first camera i have ever owned. I bought it exclusively for video, but have since fallen in love with photography using it (knowing 0 about photography before getting it). I too struggled with the blurry shot syndrome. All these sci/tech answers aside, here are my 2 cents on how I fixed that problem (and have had some shots published for that matter!)

1. Set aside some quality time (not much, a large pot of tea and a half pack of smokes would do...), use Google, and learn how aperture/shutter speed/ISO are all related and how they work together. This will fix your blurry shot problem with any camera you pick up, not just the gh2. Now then, turn your camera on with that book learning in mind, and go play.

2. FORGET AI MODE FOREVER. Use Aperture Priority mode. Set your 14-140 to f4, and let the camera do the rest. Still getting blurry shots? Crank the iso. Getting to much "noise" in your non-blurry shots? Time for Google again! (hint : post processing, noise reduction,) Shoot in RAW!

3. Lens. Listen man, i feel you. I started with the 14-140 lens, then had it stolen on a paid video gig. Best thing that ever happened to me. Went out and got a fast prime, a wide prime, and the 45-200 zoom all online, all used, and all for about the same price as the 14-140 new. IF you want sharp images in low light, you need a faster lens.

4. Forums and tech heads are no substitute for a charged battery and good old fashion fun.

Cheers! (long time reader, first time poster...)

(p.s. Some of the best shots in my collection where shot at night, on the street, with the 14-140 with the iso cranked to all hell. Noise? oh yeah. Blur? yup! Impact? you bet...)

I also have a D7000, so for me, the GH2 is more of an "artistic" camera. I use the D7000 for absolute quality, while I use the GH2 for messing with colors/split toning/etc. and the pseudo Tri-X mode. I shoot mostly in Aperture Priority, just like with my D7000, unless I'm looking for something specific. Haven't run into any noticeable issues when using it compared to the D7000, besides the lack of phase detection AF. The only AF lens I have is the 14-42 OIS kit lens, and for what I use it for, it's perfect.

I shoot in RAW + JPG at ISO 6400, on Dynamic B&W with +2, -2, -2, which does a damn good job of emulating Kodak Tri-X 400 film. Just a slight bit of Gaussian Blur needed to get rid of the digital sharpness on the noise. That way, I have a Tri-X style JPG plus a RAW file to mess with as I please (surprisingly hard to reproduce the in-camera B&W JPG). You can also use it in ETC mode around ISO 1000 for the same look. It's incredible looking if you have a lens that vignettes a bit! :) Works the same for video, as well.

Sure the RAW's noisy at 6400 (noticeably less than I expected), but it still retains a film grain appearance and is great for a vintage look. Just went to NYC 2 weeks ago, and I have an insane amount of pics from the GH2 to work on (let my friend borrow my D7000, since he's never used an SLR before). Loving the look so far.

That said, the GH2 for normal photos is still very good looking up to around ISO 1600. The GH2's RAWS definitely respond differently in ACR than the D7000's RAWs. They do look sharper, though, even when compared to the D7000 with $$$$ lenses and primes. Wonder if it's the sensor or in-camera RAW sharpening based on the lens...

@wrleo iA always choses a shutter speed that is too slow when indoors. No way round this. Setup the camera for her (like I do with my wife) so it shoots minimum of 1/30 shutter speed and you should get less blur. Extra time to setup but at least you get useable shots.

@Mimirsan @WRLEO Anyone can achieve great photos with the GH2, some basic equipment and knowledge of how to adjust settings correctly.

Not saying these are great photos, but they were all shot with the GH2. http://www.flickr.com/photos/greenbandanakid/

If you expect crap you're going to get crap.
