Hey /p/.
I got these black squiggles on my lens, but I have no idea what to do.
Help?

Based on how sharp the objects are I would suggest that this is actually debris on the sensor, rather than the lens. Get a decent sensor cleaning kit from a local camera store and watch some Youtube videos on sensor cleaning.

I switched out the lens for another lens. The marks only appear on one lens. I'm fairly certain it's the lens.

(And yeah, I did clean the front and back glass)

get a blower and blow on your sensor

It's not the lens.
Nothing on the lens can cause this.
You probably used a wider aperture on your other test.
Sensor dust is more visible at smaller apertures.
all fixed OP
