Top cinematographers understand the advantages of high-end professional glass filters both for in-camera effects and practical exposure issues. Its about control and that’s why they also understand the benefits of effective light management and flare control that can only be done with a high-end mattebox system including flags and wings. OConnor has painstakingly come up with a solution to intuitively handle filters, and allow configuration freedom to meet just about any shooting situation.
