Removing the lens
1. Set the mirror and cock the shutter by
pushing the cocking lever as far as it will go
toward the front of the camera body.
2. Rotate the bayonet ring of the lens counter-
clockwise as far as it will go (the white dot on
the bayonet ring will align with the central red
mark on the body) and remove the lens.
If the mirror and the shutter are not cocked
l
the safety interlock will interfere with the
rotation of the bayonet ring and the lens
cannot be removed.
Releasing the shutter on a lens which
has been removed from the body
To release the shutter on a lens which
has been removed from the camera body,
turn the cocking pins (B) clockwise, while
pressing the shutter lock pin (A) with a

halfway.
