Symptoms
- Grinding or clicking sound when taking a photo
- Buzzing sound from the lens during focus or zoom
- Noise louder or different than normal shutter sound
- Noise accompanied by blurry or failed shots
Likely causes
- CommonDust or debris in the lens zoom or focus mechanismGrit can create grinding noises as internal parts move past it.
- CommonAutofocus motor working harder in low light or low contrastExtra hunting for focus can sound like a persistent buzz.
- PossibleWorn shutter mechanism after very high shutter countShutters are mechanical and wear out after tens of thousands of actuations.
- PossibleLoose internal component from a drop or impactCan create a rattling or clicking sound during operation.
- Less commonLens element or focus group physically damagedImpact damage that changes how the lens sounds and performs.
What to do
- Note exactly when the noise happens: during shutter release, zooming, or focusing.
- Try the lens on a different camera body, or a different lens on this body, to isolate the source.
- Check the resulting photos for blur or focus problems that might correlate with the noise.
- Gently clean around the lens barrel and mount with a blower to remove loose debris.
- Avoid forcing the zoom or focus ring if resistance accompanies the noise.
- Check the camera's shutter actuation count if available, since very high counts suggest natural wear.
- If the noise is new, worsening, or paired with image quality problems, have it inspected by a camera repair technician.
Tools and parts
- Air blower
When to call a pro
If the noise is new, gets worse, or affects photo quality, have a camera repair shop inspect the shutter or lens mechanism.
