Frasier, I am going to be in the path of totality for the upcoming eclipse. I have a full frame camera and a 16 step n.d. filter. Between taking photos of the eclipse, is it necessary to put a lenses cap on the filter? Or is a 16 step neutral density filter enough to protect the sensor for the entire eclipse?
