On the issue of SLR camera lenses having traces

Guess your viewfinder is dirty, see if there are oil stains on the surface or something. You take the lens off and see if the mirrors in the machine are not clean

Oh, i konw, it's your eyepiece that the pentaprism is dirty, but it doesn't affect your image quality, it's just that you see the stain when you frame it with the eyepiece.

If you have the conditions to want to clean, take it to the after-sales **, don't wipe it with a glasses cloth. If you can, you can get a lens cleaning kit (use it sparingly) and just use a blow dryer to get the dust out. Even if there is a lens paper lens, you should wipe it as little as possible, and you can also go to a professional camera to clean it**.

You shine it with a small aperture to see if there is a print.

It could be on a reflector or a framing pentamirror. See if there is one on the group mirror behind the lens.

You can go under the manual. Or ask other Nikon DSLR users that there is a button on the left side of the camera and lens mount that rotates the lens counterclockwise when pressed. It's okay, don't rub around.

You said that it affects the framing, but it doesn't affect the quality of the shot. It's best to go to a specialty store and get a different reflector.

It should be a blot on the CCD, clean it according to the following method.

First of all, there will be no traces on the ** that is shot.

Also, don't you have an instruction manual? Parallel imports, right?

If the surface of the lens is not there, and you can't erase it on the inside, it's best to negotiate a replacement with the merchant.

Don't wipe the lens with non-professional supplies!!

There is a coating layer on it, which is particularly easy to be damaged, and your traces are likely to be rubbed out by you!!

If you want to buy a professional lens pen to clean the lens, the lens is very delicate, so you must protect it well!!

Summary. Hello, 1 one is that there are scratches on the lens (have you ever seen the scratch on the glass) 2 The other is that the coating on the lens is wiped off or uneven (like wiping glass).

Hello, 1 one is that there are scratches on the head of the missing lens (have you ever seen the scratch on the glass) 2 The other is that the coating on the lens is wiped off or not rented and rotten evenly (just like wiping glass).

Can you see this?

I don't see any scratches on this, so you can see it.

Selling this was rejected.

Hello, I didn't see a scratch on the ** you took a picture to show me.

What about the last two. It is possible that the buyer maliciously refuses the visa.

This one has slight scratches.
