Recommendations for high-quality protective filters for Canon RF lenses?

Honestly, you dont need to spend a fortune just to keep your glass safe. I went with the Hoya 77mm NXT Plus UV Filter for my kit and I am super happy with how it performs. It keeps the mud and dust off, and I honestly havent noticed any drop in quality. It works well and stays within a decent budget, which is a huge win!

To add to the point above: while the top-tier filters are great, I'm gonna take a slightly different stance here regarding the budget. You really dont need to drop a hundred bucks to keep your RF glass safe. I actually prefer an approach that saves money for more gear or travel. Honestly, if you use the lens hood that came with your lens, you're already 90% protected from scratches. Hoods are basically free and offer way better impact protection than any thin piece of glass ever could. If you're still set on a filter for dust or moisture protection on your hike, there are plenty of mid-range options that wont mess with your image quality. I've tested a few and these are solid, budget-friendly choices:

• Kenko Realpro UV Filter 77mm
• These are made in the same factories as some much more expensive brands and the coating is surprisingly easy to clean.
• Tiffen UV Protection Filter 77mm
• A classic choice thats very affordable, though it lacks some of the fancy coatings of the high-end stuff.
• Marumi DHG Super Lens Protect 77mm
• This one offers a great balance of price and performance without the huge marketing markup. Basically, unless you're shooting directly into harsh sunlight all day where flare is a massive issue, you wont see much difference between a $40 filter and a $120 one. Stick to the reputable mid-range brands and you'll be fine. I'd even suggest checking for open-box deals at camera stores to save another $10 or $15. It adds up...

Good to know!

Saw this earlier while I was out and wanted to weigh in because filter quality actually matters a ton if you're shooting high-res RF glass. In my experience, if you put a cheap piece of glass in front of a $2k lens, you're gonna lose contrast and get nasty ghosting when shooting into light. Tbh, after testing many over the years, I only trust stuff like the B+W Master 010 UV MRC Nano Filter these days. It uses high-end Schott glass and has a brass frame so it wont get stuck on your lens threads like cheap aluminum does. Another solid pick for technical performance is the Breakthrough Photography X4 UV Filter. Their lab data is basically the best in the industry for light transmission and color neutrality. Just make sure the diameter matches your specific lens... lemme know if you need help finding the right size for your RF kit.

Nice, didn't know that
