Hello everyone, I wanted to get some feedback on lee's seven5 and 100mm filters. I currently have an assortment of Tiffen filters from .6 to 3.0 stop. While I like them for my Sony 10-18mm I am constantly feeling that the lee system would do better. What really interest me are the lee graduated filters. So before I jump into my questions I want to give a little more information. I currently shoot on an A6000 with sonys 10-18mm f4. I just picked up a metabones adaptor and I'm waiting on a canon 70-200 f4. In the coming months I will replace the 10-18 with the recently released 16-35 FE f4 zeiss lens. Then lastly move into a full frame body like the a7r. Ok now on the my question. What are the main differences between the lee 100mm and seven5? Seeing the lenses above, what system would best fit my lenses? I will probably have to get the adapters for either system to fit the different lens openings. Thanks for the help everyone!
