Post-filter will cause optical path difference to change

So we need bring it into focus when used, every time. With the ultra wide lens, the coma will be increasing obviously, proposing to tailor.

Interference filter directly to shoot the light source will flare easily which is due to multiple reflection in coating. Therefore, to avoied when shooting as possible.
