"shutter speeds about 1/250 sec, where banding can occur"

What's the sweep time with your camera? If you do not know you can find out by taking a picture of a fluorescent light with the shutter speed set high enough to cause banding. The sweep time is the number of bands divided by 2 times the AC frequency. Or number of bands /120 in the US or other countries with 60 Hz AC.

On my GX7 the sweep time is about 8/120 = 1/15 of a second which is slow enough to cause problems with moving subjects. If they could get it up to 1/60 or faster it would help a lot but the technology is not there yet.

In the E-M10II review it says:

The best option is to use the full electronic shutter, which completely eliminates the issue. There are times where you don't want to use it, though, mainly when shooting in artificial light at shutter speeds about 1/250 sec, where banding can occur.

Does this answer your question?

Despite the slow sweep speed I use the electronic shutter much more often than the mechanical one.

Yesterday and today I have been using the electronic shutter too. I like it.
