I am more concerning about the image quality and autofocus speed when using this clear filter. Does it degrade the image quality of the captured image? Does it slow down the autofocus speed at all?

Does this come with a case or pouch for the filter? The ND RF/EF adapter does not have anywhere to place the filter when it's out.
Asked by: Christopher
