150mm filter holder for Irix 11mm f/4

Irix 11mm f/4 is the ultra wide & very big lens so it is very difficult to install square filter in the front of lens, we need aslease 180mm filter system for this, but with very large system is not a good choise for travel in difficult location and weather condition. In the other hand, there are no well know filter brand name filter have such large filters in recent time.

The best sollution for this lens can be use 150mm system is cutting out 1cm of lens hood.
