What is the reason why the photos taken with SLR cameras are not clear?

1, it may be that the mode is set to manual mode, but the focal length and the distance between you and the subject are not sure.

2. It may be that the lens of SLR is not clean. I suggest you wipe it with special lens paper.

3. The automatic mode may be used. Every time you tap the shutter, the lens will automatically focus once, and each focus is different. Your subject is out of focus, which requires your own observation and grasp.

4. It is also possible that in aperture priority mode, you shot something too close to you with a small aperture.

It is also possible that your shutter speed is set too low. It is recommended that you set the camera to shutter priority mode, and then set the shutter to at least 50 times.
