Have you checked your camera body? Or try out the lens on another body?

Just a few precautions.

1. Make sure that the lighting is adequate when you test the zoom

2. Turn on the AF or AF-C to the right spot

3. Make sure the zoom is swtiched to autofocus

4. Upgrade the firmware to the latest version whatever the camera brand is used

5. Use centre point for autofocusing first

6. Make sure the aperture is below f4 before making a conclusion

If all else failed, You would love to talk to your repairs department in your region
