I've done a few island shoots and honestly the safest bet is always sticking to brands that don't mess with the gimbal balance. Since you're heading to Maui, you're gonna deal with some serious glare and bright sand, so reliability is key here. I'm always a bit cautious about third-party glass affecting the motors, so these sets are what I trust.

• Freewell DJI Air 3 Bright Day 4-Pack ND8 ND16 ND32 ND64
• These are my personal favorites because the glass is color-neutral and they fit perfectly.
• DJI Air 3 ND Filters Set ND8/16/32/64
• If you want zero risk of fitment issues, the official ones are built specifically for the Air 3 sensors.
• PolarPro DJI Air 3 Vivid Collection ND8/PL ND16/PL ND32/PL
• Great for water shots, just watch the polarization on wide pans. I'd go with the Freewell set. Maui is gonna be amazing for the Air 3... let me know if you need anything else.

Like someone mentioned, you really need to be careful with the gimbal on the Air 3 since its a dual lens setup. In my experience over the years, you dont always need to drop a fortune on the big name brands to get clean footage. Honestly, ive tried many and for a budget pick that still hits the marks, the K&F Concept DJI Air 3 ND Filter Set 6-Pack ND8 ND16 ND32 ND64 ND128 ND256 is hard to beat. They use AGC glass and I havent noticed any nasty color shifts on my island shoots. Since you're going to Maui, those ND8 or ND16 filters wont be enough. You definitely want the ND64 or even the ND128 for that noon sun if youre sticking to that 180 shutter. Another solid cheap option is the Skyreat DJI Air 3 ND Filters Set 6-Pack which basically does the same thing for less. Save your cash for the actual trip and just make sure theyre seated right before you take off... nothing ruins a shoot like a filter falling off mid-flight.

Nice, didn't know that
