Official Panasonic GH3 topic, series 3

  • @ aria i get where you are coming from and agree 60p, image control and body is great! take it or leave it, but i had both cameras last week side by side and when you get the files into a 32 bit float environ in aftereffects and apply basic curves adjustment all those so called image improvements arent visible at 200%. and the hacked gh2 certainly holds up better in post, particulalry in the head and tail of the curve (highlights and shadows). no doubt a future hacked gh3 will be a better competitor. but if max image quality is what you need, order the bmcc. just my 2 cents:-)

  • There are so many non image improvements in the GH3 that I think it's a clearly better camera. IMO the one major request I had before the GH3 came out was that Pany would give us greater levels of adjustment of the image and they did just that. It's been shown that you can in fact lower the the sharpness more than on the GH2 and not having that baked in Contrast also helps to make the image IMO a bit better. I can see clear improvements in the footage i've seen in the shadows over the GH2. It may not be a HUGE improvement but it was clearly visible and IMO more acceptable.

    Then when you add in all the new features, 60p, more buttons and dials etc. I think it's a very nice package. I'm still trying to make up my mind whether to get 2 GH2's or a GH3. The GH2 is an INCREDIBLE bargain. I'm still using my GH1, which I also think is a very good bargain for what it can do. Heck I even considered another GH1 :)

  • @ aria

    i dont get it either. they both are capable of very nice images, filmic or otherwise. id have kept my gh3 if i didnt need the dough. but frankly, the differences and improvements in image quality at 24p that i could see are slim... imho, the increased DR and highlight detail is also very, very minor.

  • @ vitaliy

    have you had a chance to shoot with the gh3 yet? curious to hear your impressions.

    i returned my gh3 and bought a $500 gh2 after running some basic comparison tests. 50mbps gh3 mode vs fm2.2, both transcode to 422hq, then into pp cs5 w/AE for grading. didnt really see anything that different in the files. id have thought that with with increased rate of sampling the results would be much better w/less macroblocking. the hacked gh2 held up better in post. 60p and body style is cool, sure.

  • I don't understand all this talk about the GH3 not being as "filmic" as the GH2.

    DO not worry, GH2 was also not so filmic compared to GH1, as far as I remember :-)

  • I don't understand all this talk about the GH3 not being as "filmic" as the GH2. We've seen direct comparison footage that proved that both cameras can look extremely close in terms of image but with the GH3 having better shadow and lowlight handling. Perhaps even a little bit better highlight handling, No Green Tint problem. The only issue seems to be a bit more sensitivity to Moire. Overall IMO if you know what you're doing I can't see why you can't get a similar "filmic" look from the GH3 that you once got from the GH2.

    The levels of adjustment are much greater on the GH3 and thus you will see footage that varies much more from user to user than was possible on the GH2 with -2/+2 as the extent of the adjustment levels. It seems now that you can pretty much turn off in camera sharpness, contrast etc. Whereas the GH2 was limiting in how much you could effect that. I think mostly the detail differences are probably due to the GH2 having more Contrast and Sharpness baked in. Whereas many of the GH3 test shots have been -5 across the board.

  • Found this on Vimeo - did not see it posted here.

  • the GH2 had analog-to-digital conversion directly on the sensor, and the GH3 does it all afterwards.

    It is incorrect statement. In GH3 it is all the same :-) And sensor speed is bigger, hence, more sampling, not less.

  • Well, the "magic" to the 24fps image cadence on the GH2 is the Intra-frame encoding the patches allowed. It makes sure that there is no temporal-compression going on... because in film and high-end digital cinema... there's no temporal compression like long-GOP encoding. So far, in the GH3 and the Intra-codec look very good as far as motion cadence goes. It's just something about the sensor, that perhaps, is not fully sampling the same amount of detail. From what I heard last, (and it could still be wrong) the GH2 had analog-to-digital conversion directly on the sensor, and the GH3 does it all afterwards. So there may be an extra step in processing that takes a hit on detail sampling because of it.

  • @Butt @bwhitz did that sensor plus the hacking cabal just get something perfect about 24p cadence?

  • @Butt

    Yea, I'm trying to give the GH3 the benefit-of-the-doubt, and some videos show the potential of detail... but really, nothing yet quite has that nearly-2k resolution look of the GH2. Allot of it just looks like better-resolved 7D footage. Which, don't get me wrong, isn't a bad thing... but yea, that "cinematic-texture" hasn't shown up yet.

    Most likely though... people just haven't nailed the best settings for in-camera processing. And I would just like to see someone really perfect the detail-settings before I go ahead and order one. ...just to be sure.

  • @Manu4Vendetta - all looks so by video - not as cinematic as the GH2

  • @gib Photography for there are better systems. . . I would rather use the GH3 for film

  • @PhilMyself what are you thoughts on the x2 digital zoom for video. How much does quality suffer?

  • The silent electronic shutter is my favourite feature on the GH3, it's great for timelapse, but could be useful for stealthy photos of wildlife, etc

  • I have to say I was reluctant to buy this cam because of the moiree, but after seeing the test at Provideocoalition, I was quite amazed to see that the stair stepping is better on the GH3. Personally, I find the stair stepping to be more annoying than the moiree, although either can ruin a shot. The silent shutter is a huge plus, in fact, I would buy the cam just for the silent shutter feature if I can use it reliably for stills. So I guess I will join the upgrade avalanche barring a January surprise from Canon.

  • @RatLabProductions Battery grip has no extra battery with it. You'll have to buy extras separately.

  • Some experimentation with the numeric zoom X2 mode in the GH3:

  • Does anyone know if the battery grip comes with a battery or is it another purchase? I've had trouble finding clarification online.

  • @Jspatz thanks for the info.

  • @driftwood Did you modify any of the default natural settings?

  • The Ninja was very slightly different but not better. I just sold it as it is not needed on the GH3 and I get less detail on the D800e with no discernible improvement in my ability to key.

  • @Jspatz Did you record some footage straight to an Atomos Ninja? If so, how is the quality compared to stock? I am quite curious...
