When it comes to lens filters, you need them! You will be unable to capture the motion needed without them...

But infact you only need 3 filters...

• ND64 (6 stop)
• ND1000 (10 stop)
• CPL (circular polarizer)

The square filter set is absolutely the best system on the market for doing rigshots but can be used for all of your photography. I never leave home without my set!

For the more budget conscious the circular filters get the job done!
