    So being new to micro 4/3 I am probably just unaware... In low light my g7 display, either rear screen or EVF, lags, making handhold in impossible. Even when using a fast, it does this. It does not seem to be prevalent when using Panasonic lenses, but all I have are the 14-42 and the 25 1.7. It mainly happens when using lenses on an adapter... The longer the lens the worse the lag.

    It makes me wonder if it would make studio work difficult.....

    So is this normal?

    It's not really "lag", it is showing you the shutter speed effect, you are seeing close to the actual blurring effect you will get in the picture at the shutter speed you or the camera have selected. You are seeing it in low light because you are winding up with slow shutter speeds. The "cure" is to get your shutter speed up to 1/30th of a second or faster if possible. My main focus is on video/motion picture and this effect is not displayed in that mode.

    I just checked with my G7 and "kit" 14-42mm lens and 1/30th gave me a fairly steady unblurred evf image in dimmer areas of several rooms in my home.

    This seems to be common with all EVF and "live view" image finders. I've seen it with my GH4, GX7, and previously owned OMD E-M5, GH2s, GH3s, and GX1.

    I use Manual exposure mode most of the time and can readily see how this will affect my image. If handheld, ways to tame it are to brace up against a tree, wall, door jamb, etc. Hold the camera as still as you can.

    Longer lenses will appear to magnify the effect.

    I wouldn't think so since most continuous lighting you should use would get the light levels up to where you would use 1/30th to 1/60th second shutter speed. If using studio strobe most "real" studio units will have enough modeling light output that would give you enough light for you to use around 1/60th second shutter speed.

    Yes, nothing is wrong with your camera. Have fun with it, it is one of the best performers for the price.

    Turn off the "constant preview" in the custom settings menu. See if that works for you.

    The display gains up in low light, so you can see what you are actually shooting. It should not affect your image at all if you have the proper exposure. Of course, if it is that dark you might not want to shoot hand held anyway, due to slow shutter speeds.

    Hi, this same thing is happening to me with the GX85. I'm getting the feeling that this is normal operation with Panasonic cameras in general, which, honestly, sucks! It happens whenever there is low ambient light, independently of the shutter speed, ISO mode, M/S/A/P mode, etc. Only in video mode the refresh rate of the LCD seems normal and fast. Is this really done on purpose in Panasonic cameras? It's so annoying it's hard to believe.

    Have you tried turning "constant preview" off?

    Yes, I have. This has nothing to do with constant preview (which is only available in M mode). The lagging is much more notable with constant preview, but the lagging I am talking about, which appears every time the ambiente light is low (independently of the mode or constant preview being on or off), is bad enough. Here's an example: Only in video mode this lagging disappears. Don't other Panasonic cameras users have noticed this?

    Are you shooting raw or jpeg? Certain effects/filters cause quite noticeable lag on my GX8, they're only applicable in jpeg, but other than that, no, I've never noticed it

    My best guess is Panasonic does it purposely. Since G6 it's said Panasonic introduced the low light AF ability by lowering the refresh rate to 15fps

    This is really the only Panny feature that drives me absolutely insane (and I don't understand why they do it this way). My Olys and Sonys don't do this.

    Is this lag lens dependent? I didn't notice this problem until I tried out the Oly 40-150 f4-5.6 in a dim room. It wasn't a problem with Pan 20 f1.7 or Oly 9-18. Is there a hack to work around this? It is really an issue if I want to shoot concert with a telephoto lens.
