I haven’t tried it all that much, but it was definitely better. I’m using the RF50 so no birdingAnd how effectively does this eliminate lag in the EVF when used with RF lenses? We've had comments that the EVF display lags behind real life in bird-in-flight and other action scenarios.
Is High Speed Display enabled by default? Looks, from the manual, like it should be. Who wouldn't want the EVF to be "more responsive, making it easier to follow fast-moving subjects"?
With it disabled I sometimes feel like the VF shows me a long exposure freeze frame with lots of motion blur for a bit to long. But with the RF50 and enabled it’s much faster and shows the last shot for a split second and it goes away faster and it shows the feed again.
All in all it makes tracking that much easier.
The reason it’s disabled sometimes is due to other settings like Anti-flickering etc..
