Burst mode & tracking movement: SX50HS vs HX400V
Am new here so please be gentle
Have previously owned a Panasonic FZ100, and am very close to now buying either the Canon SX50 or HX400v but would be interested in people's experiences with the Canon in terms of how well its burst mode works? I'll mainly be using it for wildlife but am worried that I've read for anything moving the SX50 apparently blacks EVF/LCD out during burst mode which surely makes it useless to track a moving animal or bird. I'm unsure if the HX400 blacks both out as well during burst mode.
Also how good is the SX50's autofocus for locking on to moving things and tracking, especially if zoomed in? I'm wondering if either camera realistically is going to catch say a bolting hare a hundred metres away?
Any advice on which (SX50 or HX400) would be better for moving wildlife would really help me decide.
