Phil, if I wanted to shoot at 1.4, on the Otus, in LA on a bright sunny day, what strength ND would I need? Obviously a lot of variables, just take a swag. I really miss the motion mount!![]()
Using the sunny f/16 rule, we have a starting point of ISO 100, 1/100, f/16.
ISO 800, 1/50, f/1.4 is 11 stops ND (3.3). In my experience, usually something between 8 and 10 stops is what you'll want to cover most of outdoor wide open scenarios!
