my first post here.
I own a Bronica SQ-Ai with 40 and 80 lenses. The 95mm thread size of the 40mm makes the use of threaded filters unpractical ($$$$).
I was searching for a square filter system such as the Cokin type. I found another manufature Lee which also seels square filters at a much higher price.
What is the difference from the Cokin to the Lee filters?
