Vixia HF G50 Blurring when zooming

[pjayhart]

I shoot sports with a Canon Vixia HF G50. When I zoom in the image blurs and then when i stop zooming it takes a fraction of a second before the image clears. I shoot Lacrosse on a large field. It is very frustrating because I shoot in 4K and the action video when zooming is NOT good. 

Please help!

Thanks in advance!

I'm fairly certain that the lenses in these camcorders are not parfocal.  Thus, if you currently have focus and start zooming, the camcorder is going to have to reaquire focus as the focal length changes.  So what you're observing appears to be standard behavior for this equipment.

It's very annoying when your at an airshow filming. i thought perhaps there was a infinity zoom setting that locked the focus so it didn't hunt or search as i call it. my old sony had that feature which was great . i also thought about trying to use manual focus but i can't seem to figure that out either. I'm very disappointed in this,my first canon video camera. 4K is has terrible  qualify compared to 1080 60fps . but then i didn't buy a 1080 camera . then i had to send it back to get rebuilt as it had a strange noise when using it.
