I've got a question about infrared focus compensation. I have a Nikon
80-400m zoom lens and in the documentation for that lens Nikon states:
"When shooting black and white with infrared film, it is necessary to make
slight manual compensation to the focused distance. With color infrared
film , no compensation in focus is needed."
So my question is why could there be a difference in the focus
compensation
between B&W and color film? After all focus is focus.
