HELP (blur)!!!!!!!!!!!!

[lisa33]

I just bought a canon xl1s off of ebay from a seller with great feedback. When I turn it on and look through the viewfinder it will focus and then out of nowhere not even 5 sec later blur horribly (a pulsating blur, in and out). Is this something that I set wrong on the camera or did this person drop the camera and now it is a mechanical problem???

I am not really qualified to comment on video cameras, but it sounds like it's hunting for focus. Try to use it in better light, or point it toward a "contrasty" light source to see if it will lock focus there.
