Why are my Canon 1100D photos suddenly blurry, even with a tripod and fast shutter speed?

My Canon 1100D used to produce sharp images, but recently most photos have become noticeably blurry. This happens even when I use a fast shutter speed, place the camera on a stable surface/tripod, and use the self-timer to avoid camera shake. Are there any camera settings I should check or recalibrate, or is this more likely to be a lens problem?

Not a lot comes to mind on the camera body side, but several things may result in blurry/out of focus photos on the lens side of this problem.
- Auto-focus switch set to On?
- Image stabilizing switch set to On?
- Image stabilizing malfunction?
- Smudges/dirt on the front element of the lens?
- Smudges/dirt on the rear element of the lens?
- Auto-focus malfunction? Stuck focus ring?
- Fungus growth inside lens?
- Moisture condensated inside lens?
- Internal misalignment of lens elements after a hit/bumb?
To test some of these, first check and clean both ends of the lens, set camera to Manual focus, Image stabilizer Off, small aperture (f/16-f/22), fast shutter speed (1/250 sec or faster) and place the camera on steady surface or a tripod, carefully focus manually as best you can, use 10 second timer and shoot a photo of a contrasty subject in such good lighting that ISO will not raise too high (
If the result is still blurred, try another lens.

Generated from our catalog & community — verify before relying on it.
This is more likely a lens or focusing issue than a camera-body setting.
Things to check on the lens first:
- AF switch: make sure autofocus is enabled when you want it
- IS switch: if your lens has image stabilization, verify it’s working; for tripod tests, turn IS off
- Clean the front and rear lens elements
- Check for focus-ring problems, AF malfunction, internal fog/moisture, fungus, or damage from a knock
A good test is to remove variables:
- Put the camera on a tripod or solid surface
- Use the 10-second timer
- Set manual focus
- Turn IS off
- Use a fast shutter speed (around 1/250s or faster)
- Use a small aperture like f/16–f/22
- Carefully focus manually and take a test shot
If images are still blurry after that, the lens may have an internal problem or misalignment. If manual focus produces sharp results but autofocus does not, then AF may be the issue. The 1100D itself does not normally need user calibration for a sudden change like this.
