Totally agree with the sentiment that you dont need to spend 200 bucks to get great results. Ive been really satisfied using mid-range glass on my Sigma Art lenses for a while now without any real complaints. The trick is basically just finding a slim profile so you avoid that vignetting at the wide end since that 82mm thread is so huge. Since youre heading to Iceland, prioritize a solid CPL over a UV filter for those waterfalls:

• Hoya 82mm NXT Plus Circular Polarizer is very thin and usually runs around 80 dollars.
• Marumi 82mm DHG Super Circular P.L.D is another great Japanese-made option thats easy to clean.
• K&F Concept 82mm Nano-X Circular Polarizer works well if you want to save a few extra bucks for gas or food. Honestly, these wont make your expensive lens look like trash at all. Just keep your hood on and youll be fine...

I would suggest being really careful with ultra-budget glass on that Sigma Art. Iceland is brutal with the mist and wind, so you definitely need a decent coating.

• Look for the Hoya 82mm Fusion Antistatic Next Circular Polarizer because it actually repels water drops and dust.
• Check out the Tiffen 82mm Digital HT Circular Polarizer for a thin frame that wont vignette at 24mm. Just make sure whatever you buy is multi-coated or you'll get some nasty flares.

Big if true

Honestly, the cheaper glass I tried was not as good as expected once I got into the field. It was pretty frustrating and Iceland is gonna be wet and messy, so you need gear that is actually reliable.

• Just get any slim circular polarizer from B+W because those brass frames are much more reliable and wont get stuck on your lens thread when the temperature drops.
• Go with any glass from Breakthrough Photography if you can find it within your budget because they are way better at staying color neutral.
• Unfortunately cheap coatings are a total pain to clean when they get misted, so avoiding the bargain bin brands is for the best if you dont want to spend the whole trip scrubbing glass.
