One small mark on the front element

No a problem when shooting wide open

There might be ways to treat the problem , polishing the glass or a front element replanment of course

I don’t think it needs replacing though, for the right shooter/shoot it’s not a problem

Other than the mark on the front element, the rest of the lens is perfect

I’ve taken some images shooting into a light source of the lens used at

(first photo 1.4)

And the (second photo at F7)

9/10 you’d never notice the mark I believe

Who shoots this lens at F16 anyway
