Photo lag with 4 Pro

[agrafton]

When I'm in the camera mode with my 4 Pro and the camera set at 1/500th shutter speed when I take a photo of a moving train while looking FPV I don't get that exact image I saw. What is this lag called ? digital ? or am I spoiled by my DSLR. any ideas on correcting.
Thanks, agrafton

lag in your liveview is usually caused by running the app on a phone or tablet that's not got enough performance to do it properly.
With a good fast tablet, lag should be too small to be a concern.
