So I've been a die-hard Sigma Art user for like five years now, usually sticking to the 35mm and 50mm primes for my portrait work. I just grabbed the 85mm f1.4 DG DN for a big destination wedding I'm shooting in Maui next month and it's the first time I'm actually worried about the salt spray and that harsh Pacific sun hitting the front element. I usually never use filters because I'm a bit of a purist about that Art series sharpness but I'm starting to think I need a solid CPL or maybe just a high-end protector that wont mess with the bokeh. Do you guys find certain brands play better with Sigma's coatings or should I just stick with the lens hood and pray?
Jumping in because I totally agree about the salt. Over the years, I've found B+W 77mm XS-Pro Clear MRC-Nano 010 Filter holds up best against the elements without killing that Art series micro-contrast. Its way cheaper than a front element repair, honestly. Quick tip: bring a fresh microfiber and some Giottos Rocket Air Blaster Large to blow off the dry salt before you even think about wiping the glass.
In my experience shooting coastal events over the years, relying just on a lens hood is a massive gamble. Salt spray is basically liquid sandpaper once it dries on your glass. I have tried many different filters and honestly, the modern ones dont mess with the Sigma Art sharpness like the old cheap stuff used to. You need something that can handle the Maui humidity and salt without making your life difficult or breaking the bank.
That 85mm is absolutely amazing! I took mine on a windy coastal shoot last year and the salt mist was everywhere, total nightmare. Quick tip: get a filter with a hardened coating so you can wipe it easily. Are you planning on shooting wide open at f/1.4 in that bright Maui sun? If so, you'll definitely need an ND. Otherwise, I love the Hoya 77mm HD3 UV Filter for keeping that Art sharpness intact without breaking the bank!
