Another possibility is that the shutter speed is too slow, resulting in motion blur. Additionally, using a high ISO setting in low light conditions can also lead to blurry photos. It's important to check these settings and make sure they are properly adjusted to ensure clear and sharp images. **

Additionally, the camera also has a bulb mode, which allows for exposures longer than 30 seconds when using a remote shutter release. **
