Focus the Viewfinder
Lift the diopter adjustment control and 
rotate it until the viewfinder display, 
focus points, and AF area brackets are in 
sharp focus. When operating the control 
with your eye to the viewfinder, be 
careful not to put your fingers or 
fingernails in your eye. Push the diopter 
adjustment control back in once you have adjusted focus to your 
satisfaction.
A
Diopter-Adjustment Viewfinder Lenses

diopter-adjustment viewfinder lens, remove 
the DK-17F viewfinder eyepiece by closing 
the viewfinder shutter to release the 
eyepiece lock (q) and then grasping the 
eyepiece lightly between your finger and thumb and unscrewing it as 
shown at right (w).
