Best UV Filter for Canon RF 24-105mm f/4L IS USM
Investing in the Canon RF 24-105mm f/4L IS USM means you’ve embraced one of the most versatile “walk-around” lenses ever made. However, that beautiful 77mm front element is a magnet for dust, fingerprints, and the occasional stray branch. I’ve seen too many L-series lenses sidelined by avoidable scratches. To keep your optics pristine without sacrificing that legendary Canon sharpness, you need a high-quality UV filter. My top recommendation, the Hoya HD3, offers the perfect balance of rugged durability and invisible optical performance.

Best UV Filters for Canon RF 24-105mm f/4L: Detailed Reviews
Hoya 77mm HD3 UV Filter View on Amazon View on B&H
The Hoya HD3 is, in my opinion, the gold standard for L-series glass protection. When you’re shooting with a lens as sharp as the RF 24-105mm f/4L, the last thing you want is a cheap piece of glass degrading your resolution. The HD3 features 32 layers of anti-reflective coating that boast a 99.7% light transmission rate. What really sets it apart is the chemically hardened glass, which Hoya claims is four times stronger than standard optical glass. I’ve personally seen this filter survive a direct impact that would have certainly shattered a lesser model. The thin aluminum frame is also meticulously designed to prevent vignetting at the 24mm wide end. It is slightly pricier than consumer-grade filters, but for a lens of this caliber, it’s a necessary insurance policy. The coatings also make it incredibly easy to wipe off fingerprints and raindrops in the field.

B+W 77mm 010 UV-Haze MRC Nano View on Amazon View on B&H
The B+W 010 MRC Nano is a legend in the photography world, and for good reason. While most filters use aluminum frames, B+W utilizes brass. This is a game-changer if you frequently swap filters, as brass is less likely to “bind” or cross-thread onto your lens’s 77mm threads. The Multi-Resistant Coating (MRC) with Nano technology makes the glass surface extremely hydrophobic; water beads off instantly, and oil from skin doesn’t smear as easily. On the RF 24-105mm, you’ll notice zero loss in contrast or color fidelity. It’s slightly heavier due to the brass, but it feels incredibly premium. My only minor gripe is that the “Nano” version can be so slick that it’s occasionally hard to get a grip on if your hands are sweaty, though the knurling on the edge helps. It offers professional-grade protection and optics at a price that sits comfortably in the middle of the pack.

Tiffen 77mm UV Protection Filter View on Amazon View on B&H
If you’ve just spent a significant amount on your Canon RF body and lens, your wallet might be feeling thin. The Tiffen 77mm UV filter is the most straightforward, honest solution for basic protection. It doesn’t feature the fancy multi-coatings of the Hoya or B+W, which means it is more susceptible to ghosting and flare if you’re shooting directly into a light source. However, for everyday outdoor shooting, it does exactly what it says on the tin: it protects your L-series glass from scratches and dust. Tiffen’s ColorCore process ensures the glass itself is consistent, though the aluminum ring is basic and can occasionally stick if tightened too hard. I recommend this for beginners who primarily shoot in controlled lighting or those who just want a “disposable” layer of protection for a dusty hike. It’s a low-cost insurance policy that doesn’t significantly impact image quality for most casual applications.

Breakthrough Photography 77mm X4 UV View on Amazon View on B&H
For those who demand the absolute best, the Breakthrough Photography X4 UV is a masterpiece of engineering. Using SCHOTT B270 German glass, it offers the highest light transmission of any filter I’ve tested. What truly makes this a “Premium Choice” is the traction frame. The edges are deeply knurled, allowing you to grip and remove the filter even while wearing thick winter gloves—a feature I’ve appreciated on many cold sunrise shoots. It is ultra-slim to ensure no vignetting at 24mm, yet it feels incredibly robust. The weather-sealing on the RF 24-105mm f/4L is excellent, and adding the X4 UV completes that seal, giving you total confidence in a downpour. While it is the most expensive option on this list, the combination of elite glass, a 25-year warranty, and the functional traction frame makes it a worthwhile investment for serious professionals.

Marumi 77mm EXUS Lens Protect View on Amazon View on B&H
The Marumi EXUS is a fantastic alternative that often flies under the radar. Its standout feature is an anti-static coating that actually repels dust. If you’ve ever spent a day shooting in a dry, windy environment, you know how annoying it is to constantly blow dust off your lens. With the EXUS, particles simply don’t want to stick. It also features a water and oil-repellent coating that is among the best in the industry. The glass is mounted in a way that allows for slight thermal expansion, preventing stress on the optics in extreme heat. I find the Marumi filters to be exceptionally neutral, with no noticeable color cast. It’s a thin-profile filter that works beautifully with the Canon RF 24-105mm, offering a slightly different set of benefits than the Hoya or B+W at a very competitive price point.

Frequently Asked Questions
Will a UV filter cause vignetting on the RF 24-105mm at 24mm?
As long as you choose a “slim” or “thin” profile filter, you shouldn’t see any vignetting. Most modern professional filters from Hoya, B+W, and Breakthrough are designed with slim frames specifically for wide-angle lenses. If you stack multiple filters (like a UV plus a CPL), you will likely see dark corners at 24mm. Stick to a single high-quality slim filter to maintain full frame coverage without any obstruction or shadowing.
Do I really need a UV filter for a digital camera?
Digital sensors already have UV filters built-in, so you don’t need it for “haze” reduction like film photographers did. However, in the digital era, a UV filter is primarily for “lens protection.” It is much cheaper and faster to replace a $70 filter than it is to send your $1,300 L-series lens to Canon for a front-element replacement. It protects against salt spray, sand, dust, and accidental impacts.
Does the RF 24-105mm f/4L come with a filter?
No, Canon does not include filters with their lenses. It comes with a lens hood (EW-83N) and a lens cap, but the 77mm glass front is exposed. I recommend having a filter ready to install the moment you unbox the lens to ensure no dust ever touches the actual lens surface. This keeps the lens in “mint” condition, which is vital for maintaining its long-term resale value.
How do I clean my UV filter without scratching it?
Use a rocket blower first to remove loose grit. Then, apply a drop of lens cleaning solution to a clean microfiber cloth (not directly on the glass) and wipe in a circular motion. Filters with “Nano” coatings, like the B+W or Hoya HD3, are much easier to clean because they resist oil and water. Avoid using your shirt, as the fibers can be abrasive and eventually wear down the multi-coatings on the filter.
Can I leave the lens hood on with a UV filter attached?
Absolutely. The 77mm filter threads are on the inside of the lens barrel, while the hood attaches to the outer bayonet mount. Using both is the ultimate protection strategy. The hood provides a physical buffer against side impacts and stray light (flare), while the UV filter protects the glass from direct contact. I always use both simultaneously when shooting in unpredictable environments or crowded public spaces.
Final Verdict
For the majority of Canon RF 24-105mm users, the Hoya HD3 is the smartest investment; its hardened glass is a lifesaver for travel and event photography. If you value mechanical precision and want a filter that will never get stuck, the B+W’s brass frame is unbeatable. Professional landscape photographers should look toward the Breakthrough X4 for its superior grip and warranty. Whatever you choose, ensure it’s a 77mm thread to keep that L-series glass looking brand new.
