I would suspect the same can occur with LED lights. Especially cheap ones like Christmas lights -- they flash quickly.
Shoot even with normal shutter over 1/1000s and you may see some of the lights appear dark.
More expensive lights, like those for photography do not flash.
I shot this one in my studio with Lastolite regular flash strobes, but at the same time I'm using the cheap LED Christmas lights you see in the background.
Camera was on a tripod with 2 seconds delay and EFCS on as a testing purpose.
Īve shot same scene with EFCS off and it was good, no funky behavior 😀.
Īve shot a few landscapes with EFCS on and didn't notice any issue, nor did I notice any improvement to be honest.
