I have questions about this lens. What is the quality? There is a 1mm very faint smudge or possible fungus in the center of the rear element. What effect might this have upon black and white images? The rest of the glass is clean and clear.

Fungi are always affecting the image. Over a black area of the take,
the light it catches will register but is easily removed in post while it
will absorb some light and register a grey spot on the whites that are
also be easy to remove in an area without details.

If you can access the fungus, clean it up with high quality ethyl.

Light is free… capturing it is not!
