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 !
