Replacing the Diopter Correction Lens

★ If there is dirt or dust on the lens surface, remove it with a blower or sweep it off

gently with a lens brush.

★ If there are fingerprints or dirt on the lens surface, wipe them off with a piece of clean,

soft gauze.

★ Using solvents could discolor the diopter correction lens frame.

1. Remove the lens supplied with the finder by

pulling it downward.

2. Push the replacement diopter correction lens

upward into the viewfinder’s eyepiece frame until

it clicks into place.

Diopter Adjustment

Look through the viewfinder and make sure that the focus frame (Rectangle with Circle)

is in sharp focus. If it is not, turn the diopter adjustment dial in the “–” direction if you are

nearsighted, in the “+” direction if you are farsighted. If this is not sufficient you may

require an optional diopter correction lens. See below.

★ Point the camera at a bright, plain object such as a white wall when making this

adjustment.
