Re: [APML] Zenitar 16mm f/2.8

Hi Dominic -

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 !

Thanks.
