I second all the above. I know, I know, the ‘rule’ is to put on a UV filter. Rubbish! I use Zeiss glass and I take every precaution to protect it and to make sure that nothing gets in the way. Dirt is dirt. In 30 years, I have had only 1 small scratch and that was because I did not have the lens cap on in the bag. Meanwhile, polarizers give rich colour, reduce glare, reduce reflections and reduce small iris settings. That I will buy into. And a variable ND is a great way to go. There you have it – now go shoot some movies and spend your money on making films.
