simple question about this lens: Can you LOCK the lens at a particular focal length so it can't move in or out?

thank you.

Yep; like bobby said: Set the focal length you want, and then just dial the tension up on the tension ring.

Actually there are two rings, a white one with Smooth < - > Tight, and a black ring to tighten against.

- With the setting on Smooth, push or pull the tube to the focal length you want.

- While holding the black ring, turn the white ring toward Tight.

thanks guys. Want to make sure I can lock a focal distance setting and the lens won't be moving in and out on me. Appreciate the experienced knowledge as always.
