Best ND Filter for Canon RF 24-105mm f/4L IS USM
The Canon RF 24-105mm f/4L IS USM is the ultimate “walk-around” lens, but its f/4 aperture can struggle to provide that dreamy motion blur in bright daylight without overexposing your shots. To master long exposures or maintain cinematic shutter speeds for video, a high-quality ND filter is non-negotiable. After field-testing several 77mm options on my EOS R6, the PolarPro Peter McKinnon Edition II stands out as the gold standard for this specific L-series glass.

Best ND Filter for Canon RF 24-105mm f/4L IS USM: Detailed Reviews
PolarPro Peter McKinnon Edition II View on Amazon View on B&H
If you’ve ever dealt with the dreaded “X-pattern” on a variable ND filter, you know how it can ruin a shoot. The PolarPro PMVND Edition II solves this with a preset range that prevents over-rotation. For the Canon RF 24-105mm f/4L, I find the 2-5 stop version is perfect for most daylight scenarios. The glass quality matches the “L” series pedigree, maintaining edge-to-edge sharpness even at 24mm. What I love most is the haptic feedback; you can feel the clicks as you adjust, allowing you to change settings without taking your eye off the viewfinder. It comes with a unique “Defender” cover that offers better protection than a standard lens cap. While it is pricey, the color neutrality is unmatched—no annoying yellow or blue shifts here. It’s a premium tool that respects the resolution of the RF mount.

Tiffen Variable ND Filter View on Amazon View on B&H
Tiffen has been a staple in the film industry for decades, and their 77mm Variable ND is a workhorse for the RF 24-105mm. What makes this a “value” pick isn’t just the price, but the reliability. It offers a wide range of light reduction (roughly 2 to 8 stops), which is incredibly helpful when you’re shooting at the f/4 max aperture in harsh noon sunlight. One design choice I appreciate is that the outer ring is slightly larger than the 77mm thread size; this helps prevent vignetting when you’re zoomed out at 24mm. You might notice a very slight warm cast in some lighting conditions, but it’s easily corrected in post-processing or with a custom white balance. It doesn’t have the hard stops of the PolarPro, so you do need to be careful not to over-rotate at the extreme ends, but for the price, the optical clarity is hard to beat.

K&F Concept Nano-X VND View on Amazon View on B&H
If you’ve just spent a significant amount on the RF 24-105mm f/4L, your wallet might be feeling thin. The K&F Concept Nano-X series is the best “affordable” filter I’ve used that doesn’t feel like a toy. It’s constructed with high-quality Japanese glass and features a multi-layer coating that resists water and oil—perfect for landscape photographers who find themselves near sea spray or waterfalls. On my RF 24-105mm, it maintains surprisingly good sharpness, though you might see a slight loss in the extreme corners at 24mm. The rotation is smooth, though it lacks the premium “click” of more expensive filters. The main limitation is a subtle green tint that can appear at maximum density, but for social media content or hobbyist travel photography, it’s a non-issue. It’s a fantastic entry point that performs well above its price bracket.

B+W XS-Pro Digital ND Vario View on Amazon View on B&H
B+W is legendary among photographers for their brass frames and Schott glass. The XS-Pro Digital ND Vario is for the user who refuses to put anything but the best glass in front of their Canon L-series optics. The MRC-nano coating is the star here; it’s incredibly durable and makes cleaning fingerprints or raindrops a breeze. When shooting with the RF 24-105mm, this filter provides the most neutral color profile I’ve seen in a variable ND. It doesn’t have the “stops” labeled like the PolarPro, which might be a downside for some, but the sheer optical quality is superior. It’s also quite thin, ensuring that even at 24mm, there is zero mechanical vignetting. If you are a landscape professional who needs absolute color accuracy for high-end prints, this is the investment you won’t regret.

NiSi True Color Vario ND View on Amazon View on B&H
The NiSi True Color Vario ND is a fantastic middle-ground between the PolarPro and the Tiffen. It features a unique, removable silver lever that allows you to adjust the density with just one finger—perfect for run-and-gun videographers using the RF 24-105mm on a gimbal. As the name suggests, NiSi has worked hard to eliminate the common “yellowing” found in many VNDs. On the Canon RF system, which is known for its beautiful skin tones, this filter helps maintain that natural look without extra grading work. It has hard stops to prevent over-rotation, which is a massive safety feature for your footage. The build quality feels dense and high-end. My only minor gripe is that the lever can sometimes get in the way of a lens hood, but since you can unscrew it, it’s a very versatile piece of kit.

Frequently Asked Questions
Does a VND filter affect autofocus on the RF 24-105mm?
Generally, no. The Canon R-series cameras use Dual Pixel CMOS AF, which is incredibly sensitive. Even with a 5-stop ND, your EOS R5 or R6 will track eyes and faces perfectly. However, if you use a very dark 10-stop filter in low light, you might notice a slight hunt, but for standard daylight shooting with this f/4 lens, autofocus remains lightning-fast and reliable.
Why do I need an ND filter if my lens only goes to f/4?
While f/4 isn’t as “fast” as f/2.8, it’s still wide enough to overexpose in bright sun if you want to keep your shutter speed at 1/50 or 1/60 for video (the 180-degree rule). Without an ND, you’d be forced to stop down to f/16 or f/22, which introduces diffraction and softens your image. An ND lets you stay at f/4 for better bokeh and sharpness.
Can I use my lens hood with these ND filters?
It depends on the filter’s thickness. Most standard 77mm filters like the B+W will fit under the Canon EW-83N hood. However, variable NDs often have larger outer rings to prevent vignetting, which can prevent the hood from clicking into place. If you use the PolarPro or NiSi with the lever, you’ll likely need to leave the hood in your bag during use.
Is the 2-5 stop or 6-9 stop version better for this lens?
For the RF 24-105mm f/4L, the 2-5 stop range is the “sweet spot.” Since the lens only opens to f/4, you don’t need massive amounts of light reduction to hit cinematic shutter speeds. The 6-9 stop version is usually reserved for extremely fast lenses (f/1.2 or f/1.4) or for creating long-exposure “ghosting” effects on water and clouds during the middle of the day.
Should I buy an 82mm filter and a step-up ring?
This is a common “pro tip.” If you plan on eventually buying the RF 24-70mm f/2.8L or the RF 15-35mm f/2.8L (which both use 82mm threads), buying an 82mm ND filter and a 77-82mm step-up ring saves you money long-term. Just be aware that you won’t be able to use your lens hood, and it makes the lens a bit more cumbersome to handle.
Final Verdict
For the professional who needs reliable, click-stop accuracy, the PolarPro Peter McKinnon Edition II is the clear winner for the RF 24-105mm. However, if you’re a hobbyist just starting with video, the K&F Concept Nano-X provides incredible value without compromising too much on sharpness. Landscape purists should stick with the B+W for its legendary Schott glass. Regardless of your choice, adding an ND filter is the single best way to unlock the cinematic potential of your Canon L-series lens.
