GH3 electronic shutter mode
Dec 27, 2012

It is probably well known already that the electronic shutter mode of the GH3 produces heavy rolling shutter artefacts, much more than when using video.  Using a LEGO Technic setup with a rotating propeller, I measured the speed of the rolling electronic shutter, and found that it takes about 1/10s to read the whole sensor.

This is consistent with what I read in an interview with some Panasonic engineers.

If you could use a flash during the electronic shutter mode, this would mean that the flash sync speed would have been 1/10s. Which is, of course, extremely poor. Which is why the flash cannot be used in this mode.

Read more details about my test here:

I still find the mode useful, and use it a lot.
