Official Panasonic G5 topic

    You can capture whatever dynamic range you like within whatever bit depth you like. The two metrics have no bearing on one another.

    Hoping that manual video control and multi-aspect can be enabled by some clever sort on this camera. Would that even be possible?

  • OASYSOASYS

    Does anyone know how DxOmark can measure more than 12Ev of dynamic range for a 12bit Raw file?

  • zigizigizigizigi

    DxO has measured G5 sensor. So far it looks like it's the best Panasonic has ever released in M43 realm. Great b-cam for GH2, it even slightly outperforms its bigger brother in low-light.

    @izzy Totally agree. its what I did when I had a G3. Having the ability to lock the shutter speed is handy. The only annoyance is the AE lock deactivating when hitting record.

  • izzyizzy

    Actually i think that setting the shutter speed is sufficient for most tasks! Just use a variable ND filter to select the wanted aperture: Just switch to S mode, select 1/50 shutter speed (or whatever you have selected as flickr reduction option), half press the shutter to start metering and use the ND filter to select the aperture (while keeping iso at 160). If you now start to record a movie, it will use the selected aperture (because auto always tries to keep ISO low).

    The only problem, which remains is the lack of AE lock. But this is probably something which could easily added with a firmware hack.

  • adventsamadventsam

    Hmm, that is disappointing then ;-(

  • MimirsanMimirsan

    @adventsam

    If its like the G3 then you can lockdown the shutterspeed with the flicker reduction and works in video mode.

    You have no controls over aperture (unless using a manual lens).iso though. I also found the AE lock goes auto after hitting record. AF lock works while recording.

    You can adjust exposure (EV)..but iso and aperture (on panny lenses) will adjust in relation to it. So basically you only have some limited control on shutter speed.

    It kind of reminds me of the Nikons d5100 :-D

    I like the G5 (white one) shame no manual controls...may pick one up when cheap for the wife.

  • adventsamadventsam

    G5 video is essentially "auto" correct? except for in the manual you can ae-lock and you can add a flickr reduction option to set shutter at 1/50, 1/60, 1/100 and 1/120 and off?

    If the camera is in manual mode what happens when you hit the record button? does it auto-iso and maintain the camera settings?

    If the camera is in A or S and you hit ae-lock does it hold those settings and the iso, or allow the iso to still go auto?

    Interested in what work around there is for holding exposure? many thanks.

  • vicxvicx

    @driftwood Good to hear. After I saw the encoder perf on the GH3 test clips I was hoping someone would take a look at the G5 encoder perf.

    @kihlian The hi bitrate mov modes on the gh3 are High Profile level 5. However, G5 has comparable avchd 1080p50/60 modes to the gh3. Ill be running full tests nxt week when Im back from chile.

  • MeierhansMeierhans

    Have you red this tread???

    driftwood posted in August: Does HDMI Out work? Only in Playback mode. The G5 is UNABLE to record thru the hdmi out port showing no picture or no input in Live View or Record mode. Tested and confirmed on a Atamos Ninja and Viera TV.

  • mizamiza

    Is G5 better than GH2?

    When HDMI is connected and looking at external monitor, can we shoot 1080 50p ?

  • KihlianKihlian

    What did you mean with profile High level 5? However I´m interested on 1080p50.

  • driftwooddriftwood

    The level profile of the Gh3 (profile High level 5) is much better than the G5 apart from the 1080p50/60 modes which appear identical.

  • KihlianKihlian

    Is slowly insinuating the idea that G5 (hacked G5) is a an economy alternative of GH3? Sure GH3 has more features, better body ecc. but: same registration formats, same 4:2:0 and 8 bit. Will be interesting to see some footage comparison between GH2, GH3 and G5. If G5 really has the same sensor of the GH2 (even if it is called Venus VII), could also be the upgrade of the GH2, if it is real that GH3 has Sony sensor on no more the organic look of GH2 that many are complaining of. Personally I wait for a comparison before judge GH3, but have to say I hoped had better specifications.

    @OASYS

    It is quite simple actually. The G5 is indeed the GH2 sensor with multi aspect ratio disabled. Here is the proof.

    The GH2 has a max "Sensor photo detectors" of 18.3 megapixels. The G5 has the same. The GH3 has a max "Sensor photo detectors" of 17.2 megapixels. The G5 and GH2 simply have more pixels of the same size than the GH3 does.

    The pixel size for all three cameras is actually equal. That maintains the exact same crop factor and resolution for the 4:3 mode. You can take an identical picture in 4:3 mode with all three cameras.

    With 3:2 and 16:9 the G5 and GH3 give you cropped images with a 2.160x crop factor for 16:9 mode. I didn't calculate it for 3:2 mode.

    They definitely could enable the multi aspect ratio feature on the G5 if they wanted to. As the GH3 stands right now it is not capable of being a multi aspect ratio camera.

    @Vitaliy_Kiselev

    Thanks for the hint. :-)

    I checked the exif from GH3 Raw . It shows 4616x3080. I guess it is in 3:2 aspect. The exif of GH2 Raw shows 4760 x 3172. It's almost 100% for sure that GH3 is not capable of shooting multi-aspect photos. I'm still looking for the exif information of G5 in other aspect. If panasonic has restricted the output size of Raw as well, the last hope would be a hacked firmware. Would it be difficult/possible to modify the resolution of a still image in a hacked firmware? I remember Ptool can change the resolution of motion pictures.

  • Vitaliy_KiselevVitaliy_Kiselev

    @OASYS

    Btw, you can just test GH3 raw from samples we got (see GH3 wiki page for link)

  • OASYSOASYS

    I checked the Raw exif of various cameras in the 4:3 aspect. Here are what I've found:

    GH2: 4616 x 3460 GX1: 4600 x 3456 G5: 4616 x 3464

    Compare to the official spec.

    GH3: 4608 x 3456 GH2: 4608 x 3456 GX1: 4592 x 3448 G5: 4608 x 3456

    However, I'm not sure what 3:2 or 16:9 for G5 looks like...

  • LiamnessLiamness

    So the RAW images on the GH2 aren't cropped? Hmm, I never knew that. Must add quite significantly to the file sizes.

    I'm hoping that manual video control and multi-aspect can be added back in to the firmware by some intelligent folk. I don't really want to buy a used GH2 because the shutter count will probably be high, and I don't want to get a GH3 because it's massive. Perhaps getting an OM-D is the best bet for me, multi-aspect is cool and gets more out of your lenses, but stabilisation is also very nice to have.

  • OASYSOASYS

    It's only a guess. If the sensor of G5 is larger than that of GH3, it won't be too difficult to use the multi-aspect function in still photography. I mean, it might be poosible to use RAW output and appropriate Raw decoders/camera profiles to bypass the firmware restriction. In fact, the Raw processor I use (RawStudio) always gives more pixels than the default sizes and I can manually change the cropped boundaries for a Raw image. For example, I can get a normal 4616 x 3460 Photo for 4:3 in GH2 (default is 4608 x 3456). (Sorry, I corrected the numbers)

    I think GH3 is a complete new line for Pro and Panasonic has merged the old GH style (semi-pro or family photography) to the G series.

  • eidrageidrag

    Quick question, I'm thinking of getting this at release, but buying at Japan means there will be only japanese interface. Is there any simple hack enabling language in near future, or should I buy GX1 instead and use the other money on lenses?

    To be short.
    Fast. Quiet. Good.

  • stoneystoney

    It's confirmed. G5 uses Gh2 sensor but disabled the true multi aspects.
