With the following lenses and accessories full-aperture exposure measure-
ment is not possible, either because the lens has no auto-diaphragm or be-
cause the diaphragm will not couple with the Photomic FTN meter. There-
fore, the stopdown method must be used. This means measuring exposure
with the lens aperture diaphragm stopped down to the taking aperture. With
the Photomic FTN finder, the meter coupling pin must first be pushed up into
the finder so that the red index on the maximum aperture scale springs to f/
5.6.
Mount the lens or lens/accessory setup to the camera and switch on the meter
in the usual way.
