Are all your lenses inside have a least some of speck of dusts visible?

I think all my lenses have some dusts inside.

I think I could plant crops inside my 135mm.

If you shine a flashlight through brand new lenses, you'll see that most of them come from the factory with some dust in them.

Years a go I got a nice new Vivitar lens that had a perfect fingerprint on one of the internal lens elements.
