Hi, I am a new member and am learning so much from this forum! Now, I want to improve my long exposure skills. I own the square Lee mounting system and have a Big Stopper (10 stops). I am planning on getting a 6 stop next. It is a lot of work to set up the camera with the Lee system and I am now wondering if just using a normal round filter is a better way to go. Any thoughts on this?
Round ND filters are better for lenses that accept them because they remove the possibility of reflected light i trusion through gaps in the square filter mounting system. Also faster and easier to use.
I use the 150mm square ND and GND filters on my ultra wide lenses that do not have filter threads, and large diameter lenses over 82mm. I use screw on filters on those lenses 82mm and smaller.
