I've recently made the full jump to the Canon R-series mirrorless system, and while I’m absolutely loving the results from the new RF glass, I’m a bit paranoid about protecting my investment. I just added the RF 24-70mm f/2.8L and the 50mm f/1.2L to my kit, and the thought of a scratch on those front elements is stressing me out! I want to find the best filters that offer top-tier protection and optical performance without introducing ghosting or reducing that legendary RF sharpness.
I’ve been looking at options from brands like Breakthrough Photography and PolarPro, but I’m curious if anyone has experienced issues with vignetting on the wider RF lenses, especially since some of these have quite a bit of glass right at the edge. Also, since most of my pro RF lenses seem to standardize on an 82mm thread, would you recommend getting a high-end CPL and ND in that size and using step-up rings, or is it better to buy specific sizes for each lens to keep the hoods functional?
What are your go-to filter brands or specific models that you’ve found work perfectly with the Canon RF mount system without messing with the image quality or causing weird flares?

TL;DR: Grab the Hoya HD3 UV Filter 82mm for the best impact protection or the Breakthrough Photography X4 UV Filter 82mm for optical purity, but avoid step-up rings to keep your hoods functional. Oh man, I totally feel u on the paranoia... spending that much on the Canon RF 24-70mm f/2.8L IS USM and the 50mm is a huge investment! Ngl, I've had a bit of a disappointing run with some filters lately. I tried the Breakthrough Photography X4 UV Filter 82mm and while the glass is literally perfect, I actually had issues with the frame binding on my lens. Not as good as I expected for the price, unfortunately. If u want pure safety, the Hoya HD3 UV Filter 82mm is better cuz the glass is chemically hardened. It's way tougher than the PolarPro QuartzLine UV Filter 82mm, which I found flared a bit too much for my taste. Also, highkey, just buy native sizes. Using step-up rings means losing the hood, and u definitely need that protection on RF glass. gl! ✌️

honestly i've been there... spent a fortune on glass then went cheap on filters and completely ruined a sunset shoot with some nasty ghosting. it was basically heartbreaking seeing that $2k lens struggle cuz of a $20 piece of glass. you might find this useful—check out the LensRentals blog for their technical filter tests. they really show how much cheap glass degrades your IQ. i actually had issues with the step-up ring route. it sounds smart, but unfortunately, losing the lens hood meant way more stray light hitting the lens, which is a total mood killer for contrast. i’d suggest sticking with the B+W 82mm 010 UV-Haze MRC Nano Master Filter for pure protection. for your CPL and ND needs, the Kase Wolverine 82mm Magnetic Circular Filter Professional Kit is pretty great because it lets you swap fast without the vignetting issues you get with bulky stackable rings. just dont skimp on the coatings!

Similar situation here - I went through this exact panic last year when I finally upgraded to the R6 and those same L-series primes. I mean, spending $2k+ on glass and leaving it exposed? Seriously scary stuff. I was super cautious because I've seen cheap filters basically turn a sharp shot into mush. I ended up grabbing the B+W 82mm Master Clear Filter with MRC Nano Coating for my daily drivers. Honestly, it's been a lifesaver for my peace of mind... I actually bumped my 24-70 into a tripod leg once and the filter took the hit instead of the element. I tried the step-up ring thing at first to save some cash, but it was such a hassle since the hoods wouldn't fit, which felt risky. I eventually just bit the bullet and bought dedicated sizes for everything. Also, on wider glass like the Canon RF 15-35mm f/2.8L IS USM, using slim versions is key so you don't get that nasty vignetting. It's an extra cost, but yeah, safety first!!
