I got a used 35mm SLR minolta camera...?

Question

when i look through the viewfinder, there seems to be some dust. I took the lens out and clean it with a dry paper but there still seems to still be dust. Does this really affect the picture quality when i print it?

Answer 1

The dust is in the viewfinder or on the mirror surface, or both.

A such it wont affect image quality as the mirror flips up when you take the photograph, so the path is clear from the lens to the film.

Dust on the lens shouldn't be a problem generally as the lenses can't focus that close.

Answer 2

No, the dust is on the viewfinder mirrors/lenses in the body of the camera.  Check it out when you have no film in the camera

Answer 3

No, the dirt doesn't come up in your photos, unless you're using a very long exposure, then you'll get some particles in your images.
