It has a flower-shaped hood specifically for attaching and removing filters.
In here: "http://kmp.bdimitrov.de/lenses/primes/wide-angle/FA31f1.8.html"; You will in fact find the quote: "It even comes equipped with an exclusively designed flower-shaped lens hood, which not only cuts down excessive light but also allows for easy attachment and removal of filters." So, filter + hood = no problem. Precisely how the hood attaches, though, I have no idea.
