Attaching a lens
Notes
• The shutter is not released if the lens is not attached, except when the mode dial is 
set to M (page 55).
• Using a DT lens is not guaranteed because the corners of the field are darkened and 
the camera does not meet the primary AE performance standard.
To remove the lens
1
Remove the body cap from the camera and the rear cap from 
the lens.
2
Mount the lens by aligning the 
orange index marks on the lens 
and camera.

Turn the lens clockwise until it 
clicks into the locked position.
• When attaching a lens, do not press the 
lens release button.
1
Press the lens release button all 
the way in and turn the lens 
counterclockwise until it stops.
• When changing the lens, quickly 
change the lens away from dusty 
locations so as to keep dust from 
getting inside the camera.
