It has an infinity mark.
However like all motorised lenses, the lens can twist past this point (i.e. lens doesn't stop turning like it would with a manual lens).
Would switching it to MF (Manual Focus) not overcome that?

This is a great value lens. You also need to turn off the IS when using it mounted. It has manual override of AF too, but should be used in MF for astro-photos with a review of trial shots taken.
