Do you know why this is? Isn't just a clear filter. Since
it's needed for the lens to reach focus at infinity, it seems to me that
it's acting more like a corrector of some sort?
Weird....

Hi Chris !
Yes you should have this filter or the other colored filter to have the
focus at infinity. You can make the test visualy in daylight , you'll see
that you should have the clear filter for a good focus !
Let us know when you'll have an astrophoto with this lens that I
find verry useful.
Clear skies !
