Originally posted by UncleVanya For those using it frequently - do you see a battery impact? Maybe that's why it is only via the explicit button push?
I couldn't see the impact on battery being significant, but constant illumination would certainly interfere with trying to see your subject when its dark. The lines glow so bright they tend to obscure the view. The old tiny red block popping up momentarily didn't seem so intrusive, yet it way very helpful.
Some in between would be nice, but for now hitting the button on the side of the camera when I need a quick assist works pretty well.
