I recently invested considerable sum into the Lee filter system for my Nikon D850. This app is a perfect match, allowing me to quickly calculate proper exposure for various filter combinations. While I have yet to shoot in the field since getting all my filters, I've played with the app enough to know it will be quite handy. It also got a recent update, so its nice to know development is active.
Must have!

Important - each instrument has own very informative and helpful HELP menu, as well as a learning base. Beside that - quick, professional and friendly customer support. Highly recommended and huge respect to authors and developers!
