Customer Question
My Nikon D3400 is...

My Nikon D3400 is losing the auto-focus at various levels of lens extension. If I tinker with it, it will get back in focus, but then loses it again erratically.

Technician's Assistant: What Nikon model do you have?

D3400

Technician's Assistant: What have you tried so far with your Nikon?

I move the lens range in and out slightly and that sometimes helps, but not always.
