About Super Precision Matte Ec-S and Maximum Lens Aperture
• This focusing screen is optimized for f/1.8 to f/2,8 lenses.
• If the lens maximum aperture is brighter than f/1,8, the center spot
metering circle and Area AF frame might become difficult to see.
« Also, if the lens maximum aperture is slower than f/2.8, the viewfinder
will look darker.
E2 • Since the Ec-A, Ec-B, Ec-I, and Ec-L focusing screens have a prism at
the center, correct exposures cannot be obtained with evaluative
metering and center spot metering. Use either center-weighted average
metering or AF point-linked spot metering (except the center AF point).
• To change the focusing screen, refer to the instructions that come with
the focusing screen.
