Hmmm, not so sure. These guys have no incentive NOT to sell filters and they say this on their site as well under a dedicated GoPro filter page—that is they say for pre 6 filter yes but not for 6. And although I love the Backscatter guys the Flip filters really don’t work well, cf @caruso’s comments above. Anyways I’m going to CZM soon and will shoot without filters (and with lights if st depth) and will report back.
