>>3644617I made some quick prints. Now tell me, is it really out of focus? I don't remember the exact subject distance, but it might have been between 2 and 3 meter. Online DOF calculator says focus area is between 15-30cm at f/1.4. So, if it is oof, I might have to adjust the lens' focus. I'm not looking for back pats here and the reason for the filter are useless one word (sometimes not even real words) replies.
I had to google the number of aperture blades.
