E-M5 - changing aperture doesn't change live view

    Got my E-M5 2 days ago and changing aperture doesn't change live view picture (tested in all modes) - the view itself looks like it's stuck on minimum value.

    However, pictures are taken correctly and exactly the same thing happens on two different lenses. Thoughts, ideas?
  2. That is correct. The live image view gives you the correct preview of exposure, but not depth-of-field (unless by coincidence your selected aperture is the same one the camera is using in live view). You can however assign depth-of-field preview to a function button.

    AFAIK, the lenses stop down only when you make the photograph. There must be a DOF preview button somewhere which will help you see the DOF change. This holds good for the native lenses where as with adapted lenses (other than 4/3rds lenses), you see the DOF change as you change the aperture on the lens.

    Ah, that's true - my previous camera - Panny G3, used to update live view automatically.

    You probably just need to turn off Live View Boost.

    This...if you are only concerned about "estimated" exposure on the LCD and not DoF, turn off the boost.

    What mode are you shooting in?

    The camera will show a constant brightness image in A mode if all you're doing is adjusting the aperture, but if you have LiveView Boost turned off and adjust the exposure compensation you will see the brightness of the image change.

    Ditto in S mode, adjusting the shutter speed doesn't change the brightness of the image but changing the exposure compensation does.

    What's happening is that while all you're doing is changing one parameter and letting the camera adjust the other for the equivalent exposure, the brightness of the image in the viewfinder or on the screen doesn't change. It's only when you use exposure compensation to shift away from what the meter is recommending that you get a change in brightness in the viewfinder or on the screen, which I think is a good way to have things work.

    Oh, and of course you will also see a change when you use depth of field preview.
