4. Adjusting Zooming Resistance
Move the zoom ring forward or backward to zoom.
● Be sure to finish zooming before focusing. Changing the zoom ring after focusing can affect the focus.
●To prevent unintended extension of the front of the lens, be careful not to set the zoom ring too loose.
You can adjust the zoom ring “touch” (resistance) as needed by holding the focusing ring in place and turning the zoom touch adjustment ring.
Turn the zoom touch 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 zoom touch adjustment ring towards TIGHT until it stops.
