The radial engine comparison: I assume that that is the change in prop speed

I shouldn't have mentioned this, but thought you might have encountered it when
photographing aircraft. I did a little digging online, and think I know what I
am seeing.
I am assuming an idling prop on a PT-6 is at around 700 RPM. Let's assume 900
to make the math simple. Without finding specific data for my Fuji, let's use
a generic refresh rate for the EVF of 60 cps. This gives 4 image updates per
prop revolution. This is roughly what I am seeing through the EVF, even when
not pressing the shutter release. The thing it brings to mind is that of an
old radial engine being turned by the starter. I'm showing my age here. :-)
