My Canon 7D Mk ii paired with the 100-400 ii lens has developed a bit of a focusing issue. I depress the shutter button halfway to initiate focus, and the lens zooms in and then zooms back out to a complete blur, failing to achieve focus. It occurs on more than one focus point. It’s intermittent—that is, it doesn’t happen consistently, but happened a whole lot in my last shoot. Cause and solution anyone?
Thanks.
Is the focus-point set for single spot, or multiple/all spots, which is trying to guess on a good focus setting? Do any other lenses exhibit your problem? Could be camera doesn't know where to focus, or could be a lens issue.
