Camera lens on a small amount of dust is not a little impact on the quality of imaging?

Answer:

Specifically, the following two cases are included: 1, with a large aperture shooting If you shoot with a large aperture, the impact of dust on the imaging of the naked eye can not see the basic. And we routinely use a large aperture when the majority, which is a lot of people think that dust has no effect on the reasons for the image.
2, small aperture shot specific objects If you use a small aperture to shoot light objects, such as making blue sky and white clouds, quality will appear spot. Of course, if the amount of dust is particularly small, such as a small number of particles. Then in all cases will not affect the imaging.
If the lens is not much dust, can not ignore him Do not listen to people say, to buy something that is not cheap to come back to rub, as the lens is not good If the camera is UV mirror before the dirty, it does not matter, can change one Lens words, alcohol rub, the impact of the lens may be smaller, but can not rub, absolutely not rub.
