The rotating front part does make a bit harder to use polarizer filters, but it won't stop you from using them at all, and for UV filters it will make no difference.
by harder you mean that i have to remove the polarizing filter every time i zoom in/out?
no.. you don't have to remove it.
The problem is that a polarizing filter works by rotating the filter, so it will change the degree of effect applied. So, if the front element rotates, it will change the filter position and so the degree of effect applied. You will have to do rotate the filter in the other direction to return it to the position it was before. Once you get used, you will not even care about this "down side".. I know I don't.
