Why Panasonic exposure so simple and limited?

    This isn't available on the GH4. (On the GH3 yes, but they removed it from the GH4 for some reason)..

    One way to get around the automatic video is to use the Flicker Reduction feature. I use it on my G7 all the time. Then I can set my shutter speed to 1/50 or 1/60 always, even when pressing the video start button without entering manual video mode.

    Unfortunately in all mode dial photo modes (A,S,P and M) the video recording uses always fully automatic program (P) exposure. You can choose other exposure modes for video only when the mode dial is in Creative Video Mode and you must choose those exposure modes via video menu.

    It is quite confusing. The camera should tell that the video exposure is fully automatic (P) and not what the mode the dial shows. If the camera would show exposure values the user could instantly figure that thing.

    I just switch to the appropriate photo mode, set the menu options and make a preset for the top dial 'C' settings. Now I have all the options I want instantly.

    @caveport.

    If the camera is in Creative Movie Mode (top dial) and you set the Exposure (either using the touchscreen, or via the Menu > Motion Picture > Exposure Mode) to [M] - AutoISO is not available, nor is AutoISO Limit.

    Full Manual I agree is 'full manual' - alas they include AutoISO for 'full manual' in still modes, why not creative movie mode?

    I've learned just to shoot in Shutter Priority (1/50) and ISO800 if shooting in changing light. Not ideal, but close enough.

    On my GH4:

    Auto iso limit works in video.

    Auto iso in M works in video.

    Program exposure shift works in video, even during recording.

    Maybe you should play with your GH4 a little more....

  • VeskuVesku

    GH4:

    Auto iso limit is already there - they removed it from video

    Auto iso in M is already there - they removed it from video

    Exposure values are visible in photo mode - they removed values from video

    Program exposure shift is there - they removed it from video

    They have done additional programming work to make GH4 worse??

    @vesku - Agree completely. Its so short sighted of Panasonic to not include these options / display aids.

    As to the comments, the GH3/GH4 are not high end / professional camera. Panasonic would disagree. http://pro-av.panasonic.net/en/gh4u/index.html

    I think it shows that unless you run it full manual, the GUI developers think you are stupid, so shouldn't know what the camera is doing.

  • caveportcaveport

    Well, FULL manual is exactly what it is!

  • DrDaveDrDave

    I see the values on my phone. But no auto ISO in full manual is a bummer.

  • caveportcaveport

    @Vesku OK. I understand. It does not bother me as I nearly always shoot in manual movie mode. I think changing values in varying light conditions would not be good to have displayed. It would be nice to have a full auto mode with 180 deg shutter setting.

  • VeskuVesku

    @caveport

    I am talking about video modes A,S,P,M via video menu. If using photo modes (dial) the video is always automatic and uses program mode P. The values you see are for current photo mode but not for video. After starting recording using the red button GH4 is not showing aperture and shutter and it uses very high shutter speeds in good light. GH4 is not using traditional 180 degree rule when it uses auto exposure for video. With auto exposure for video you can never know what the camera is doing.

    I think Panasonic has thought not to confuse user by showing changing auto value but the results is opposite. The user is confused because he has no idea what is happening. With S one may use happily aperture f22 and wonder why GH4 videos are so soft (I have done it). With A user may have completely odd shutter speed and with auto iso the GH4 may use iso6400 and the user wonders why videos are so noisy etc, etc...

    It is funny that I must use Exiftool to check later at home what exposure values I was using during shooting.

    S-priority set to 180 degree shutter (1/50 for 24p) is an easy way to shoot AE video on a panasonic body.

  • caveportcaveport

    I must be doing something wrong. I see shutter speed, aperture, and ISO on my GH4 when I shoot video in Movie mode or in S, A or P photo modes. In P mode I need to adjust the aperture/shutter dial on the camera to activate the display.

  • VeskuVesku

    @Fran_Guidry

    Try S, A or P or auto iso. I must dial to photo mode and check what the automatic values may be and then back to video mode.

    GH4 has some unusual "professional" exposure features like shutter speed in degrees, flicker decrease and synchro scan. And a league of frame rates from 2 to 96.

    I dont consider showing aperture, shutter and iso very sophisticated or professional. I dont think they will loose many pro camera customers if GH4 could show that info or use auto iso in M.

    I have never used those special exposure aids but every time I go shooting I am frustrated because I dont know what exposure values I am using.

  • karlkarl

    GH3/GH4 are not Panasonics "high end / professional" cameras, they offer far more expensive cameras for professional use. And that is already explaining why you won't see many (even trivial to realize) features in "consumer price range" cameras: Such features are intentionally kept away from the less expensive cameras to separate markets and to create incentives to buy the extremely pricy "professional" models.

    You can bet Panasonics product managers spend only half as much time on thinking what great new features to include into some future camera as they spend on thinking what existing features not to include in which new model to justify the pricing of the more expensive models.

    Because this is how things work. You need some manager to collect all this issues, later he must spend like 2 months of his life defending them to have any chance of implementing, and even after this all can be never done.
