After detaching the lens, place the lens with the
rear end up to prevent the lens surface and
contacts from getting scratched.
● If the contacts get soiled, scratched, or have
fingerprints on them, corrosion or faulty
connections can result. The camera and lens
may not operate properly.
● If the contacts get soiled or have fingerprints on
them, clean them with a soft cloth.

in the diagram, and turn clockwise. To remove it,
reverse the order.
After autofocusing in ONE SHOT AF mode, focus
manually by pressing the shutter button halfway
