Adjusting the zooming touch
EF 28-300mm f/3.5-5.6L IS USM

Move the zoom ring forward or backward to zoom.

You can adjust the zooming "touch" (resistance) as needed by holding the focusing ring in place and turning the adjustment ring.

Turn the adjustment ring towards the word SMOOTH to reduce the zooming touch, or towards TIGHT to increase it. To lock the zoom ring in place, turn the adjustment ring towards TIGHT until it stops.


  • Be sure to finish zooming before focusing. Changing the zoom ring after focusing can affect the focus.
  • To prevent unintended zooming when not shooting, be careful not to set the zooming touch too loose.
  • This lens can partially obstruct the light from the built-in flash units. To avoid this, use an external flash.
