Found this fascinating. Thought I'd pass it along.

Like everything, you don't get something for free without giving up something else. I'm going to buy a HSS flash for my FF digital (DSLR) camera. I'll be using it almost exclusively for fill flash, so thanks for the link. I'm going to have to read more about this subject.

I wonder if this is why Fuji has not offered IBIS (such as on the XT-2 or XT-3)? Reading more carefully I do not think this is related to ibis.

Which «IBIS» or «ibis»?

The XT-2 and 3 do have OIS (optical Image Stabilization) on some lenses.

Fuji does offer ibis in the X-H1 but this has nothing to do with ibis

Do u have to use EFC for HSS? My Leica R9 does HSS and it does not have EFC. Just yer basic electro mechanical shutter.

My Pentax K1 is suppose to be set up for HSS, but good point I have no idea what kinds of shutter configuration my camera has. And the Godox flash I'm looking at is small but is designed to work on my camera (HHS).

Thanks – this is very interesting.

What is the hypnotic appeal of a rolling electronic shutter?

The ES is potentially invaluable when:

o any audible camera noise is unacceptable
o shutter shock (vibrations) could degrade the system MTF-50
o these are rare situations.

An even rarer is concern avoiding excessive wear of the electro-mechanical shutter mechanism. Some people's work does benefit by making thousands of shutter bursts per photo shoot.

The disadvantages of a rolling ES are significant:

o any subject or camera movement could result in gratuitous and image distortion. The former is much rarer than the later. But it is possiible.

o scenes lit by lamps that use frequency modulation (fluorescent) or pulse width modulation (color LEDs) often display banding artifacts.

ES artifacts are unpredictable, you never know when they will be significant.

And now we have the bokeh effect as well.
