Does a small amount of dust on the camera lens have little impact on the image quality?

If no conditions are set, it can be said that dust has an impact on imaging.

Specifically, it includes the following two situations:

1. Shooting with a large aperture

If you shoot with a large aperture, the impact of dust on the image is basically visible to the naked eye. Not coming out.

We mostly use large apertures for daily shooting, which is why many people think that dust has no impact on imaging.

2. Shoot specific objects with a small aperture

If you use a small aperture to shoot luminous objects, such as blue sky and white clouds, spots will appear on the image quality.

Of course, if the amount of dust is particularly small, such as a small number of particles.

Then it will not affect the imaging under various circumstances.
