Top lens filters for Canon RF landscape photography?

Curious about one thing: are you planning to stack like 3 filters at once? Cuz that basically dictates the system. - Haida M10 Filter Holder + Haida M10-D Drop-in CPL Filter (best value tbh)
- B+W 77mm Master CPL MRC Nano (pro choice for slim screw-ons) If you dont stack, slim screw-ons are way cheaper and lighter for hiking, but yeah... let me know! gl

i went through this last year and did a deep dive into prices. i found that Kase Wolverine Magnetic Circular Filter Professional Kit is way better value than bulky setups and i get zero vignetting at 14mm. honestly, if ur on a budget the Urth Filter Plus+ Explorer Kit is another solid pick. super happy with the quality tbh!

In my experience, i recommend:
1. NiSi V7 100mm Square Filter System - NO vignetting, but its pretty bulky.
2. Hoya Fusion One Next Circular Polarizer - thinner, tho still clips corners. gl!

Oh man, I totally feel you on the 14mm struggle. That Canon RF 14-35mm f/4L IS USM is an absolute beast for landscapes, but it's sooo wide that vignetting becomes a real headache if you aren't careful. Honestly, I've spent way too much time testing stuff out, and if you're looking to save some cash while keeping that RF glass sharp, I'd probably skip the massive square systems for now. They're bulky and the high-end kits are just crazy expensive. Here is what I recommend for a budget-friendly but high-quality setup: * Buy 82mm filters for everything. Use a Sensei 77-82mm Step-Up Ring for both lenses. Using larger filters is the best way to avoid those dark corners at 14mm.
* For a CPL, the K&F Concept Nano-X Pro Series Circular Polarizer is amazing. It's usually around $70-$90 and basically competes with filters twice the price.
* If you need ND filters, check out the Haida NanoPro MC ND3.0 10-Stop Filter. It's super neutral and way cheaper than the Breakthrough stuff. I actually tried the Breakthrough Photography X4 ND and it's killer, but for the price of one, you can basically get a whole set of K&F or Hoya stuff. Basically, just make sure you get "slim" or "ultra-slim" frames. If the ring is too thick, itll show up in your corners at 14mm no matter what you do. Hope that helps you save some dough! peace.

Funny you mention the vignetting issue because it reminds me of a trip I took to the coast a few years back with my old mentor. He was a real stickler for glass quality and had this massive collection of vintage filters he swore by. We were trying to catch the tide coming in, and he was so focused on stacking these thick glass plates to get the perfect long exposure that he didnt notice his tripod was slowly sinking into the wet sand. By the time he went to trigger the shutter, the whole rig tilted forward and his entire filter kit ended up face-down in a saltwater puddle. We spent the next three hours cleaning salt crust off everything instead of shooting the sunset. It was a complete mess but he just laughed and said that was the price of chasing the perfect shot. Seeing that happen really stuck with me... makes you realize that sometimes the most reliable gear is whatever doesnt get in your way when the light is changing fast. Its definitely a lesson I wont forget anytime soon. Been satisfied with my simple approach ever since.

I'd actually suggest a different approach. Standard screw-on rings often jam and stress RF barrels... pretty risky. For safety, just use any magnetic system from brands like Lee or Manfrotto to keep glass protected.

Nice, didn't know that
