Focusing Frustration: What to Do When Your Canon Camera Won’t Focus

Are you tired of frustrating moments when your Canon camera refuses to focus? You’re not alone! Many photographers have faced this issue, and it can be a real showstopper, especially when you’re trying to capture a once-in-a-lifetime shot.
