How many of you use live view for tracking subjects -sports shots etc?
I would suggest that the only LiveView system currently upto that would be Sony's - it use a separate sensor for LiveView which lets it use the normal phase detect AF rather than the much slower contrast detect.
My s9600 has a foldout tilting screen, so I use it all the time. I love using it as a waiste high viewer, or to reach over my head. Makes life easy.
That would defeat the purpose of contrast detect-AF. I am sure a faster CPU a few years later will handle it better.
