The fingerprint on the polarizer is 1. Fingerprints are not big. Will it affect the shooting if it is not clean? 2. The most effective cleaning method to avoid damaging the polarizer.

First of all, the filters mentioned below refer to polarizers, UV mirrors, decompressors, etc. Collectively referred to as filters.

After buying a new SLR, my brother will supply it as a baby. I feel uncomfortable when there is a little gray on the lens or filter.

Actually, you don't have to do this. Filters and lenses are not that delicate. Look at the photographer in National Geographic magazine. The lens is all gray, whatever. Squat behind the camera like a sniper and concentrate on taking pictures.

Fingerprints and tiny dust on filters and lenses are usually negligible. Unless a long exposure with a small aperture will have a little impact on the image quality, there will be no image quality problems in normal shooting. Of course, if it's an obvious fingerprint, you'd better wipe it. Very big dust, which can be blown by air.

In terms of cleaning, what fmengpf said upstairs is wrong. It is not appropriate to clean the filter with a lens pen. The lens pen cleans the oily fingerprints on the lens. The principle of lens pen is not to sweep, but to suck and stick. The oil is stuck to the lens by the carbon powder with the brush tip, and the oil print is "pulled" out of the lens. Remember, the lens pen is not used for dust removal. The general cleaning principle of the filter screen is that you don't need to wipe it if you can blow it away, unless there are marks on your fingers and oily prints. If you want to clean it better, you can use a special lens cloth or lens paper and wipe it with some lens cleaning liquid. I recommend Elma, a Japanese brand. When cleaning, the lens rubs in circles from the inside out. If the technique is not enough, it can be almost clean. Those experienced people can polish it as good as new.

It's convenient to protect, so it's better to cover a hood so that your fingers can't easily touch the filter and lens. And the hood is not only used for backlighting. It is correct to use the hood at any time, which can prevent the light from being led out of the lens in disorder.

Give me the best answer.
