Best ND Filter for Canon RF 24-105mm f/4L IS USM
The Canon RF 24-105mm f/4L IS USM is arguably the most versatile lens in the RF lineup, but its constant f/4 aperture can be a hurdle in bright sunlight when you want cinematic motion blur or a shallow depth of field. To maintain that L-series sharpness, you need high-quality 77mm glass. After testing various options on my EOS R6, Iβve found the PolarPro PMVND to be the gold standard, though several budget-friendly alternatives perform surprisingly well for hobbyists.

Best ND Filter for Canon RF 24-105mm f/4L IS USM: Detailed Reviews
PolarPro Peter McKinnon Edition II (2-5 Stop) View on Amazon View on B&H
If you are shooting video with your RF 24-105mm f/4L, the PolarPro PMVND Edition II is simply unbeatable. The standout feature for me is the haptic feedback; the filter “clicks” at each stop, allowing you to change exposure without taking your eye off the viewfinder. It features a preset range that eliminates the dreaded “X-pattern” cross-polarization that plagues cheaper variable NDs. The glass is incredibly neutral, preserving the micro-contrast this lens is known for. While it is a significant investment, the build quality feels like a piece of precision engineering. Iβve used this in dusty environments and the Defender360 cover provides much better protection than a standard plastic case. The only downside is the price, but for a lens this good, you shouldn’t settle for glass that softens your image.

NiSi True Color Vario-ND (1-5 Stop) View on Amazon View on B&H
The NiSi True Color Vario-ND solves the most common problem with variable ND filters: the annoying yellow-green color shift. On a versatile lens like the 24-105mm, you want colors to be consistent from wide-angle landscapes to 105mm portraits. I find the included screw-in silver lever makes adjusting the density incredibly smooth, even when wearing gloves. Itβs built with high-definition optical glass and features an AR coating that helps mitigate ghosting when shooting toward light sources. While it doesn’t have the haptic clicks of the PolarPro, its color neutrality is actually slightly better in my side-by-side tests. It’s a fantastic middle-ground option for those who want professional results without spending $250. Be aware that at 24mm, you might see very slight vignetting if you stack it with other filters.

K&F Concept Nano-X Variable ND View on Amazon View on B&H
You don’t always need to spend hundreds of dollars to get decent results. The K&F Concept Nano-X series has come a long way and is perfectly suitable for casual use on the RF 24-105mm. It uses Japanese AGC glass and features 28 layers of nano-coating to reduce reflections and repel water. While you might notice a very slight loss of sharpness at 105mm compared to the PolarPro, and a minor cool color cast, itβs easily correctable in post-processing. The frame is made of aviation-grade aluminum and is surprisingly slim, which helps prevent vignetting at the 24mm focal length. It lacks the hard stops found on premium filters, so you have to be careful not to over-rotate it into the “X” zone. For the price of a nice dinner, it’s an essential tool for any beginner’s kit bag.

Breakthrough Photography X4 Fixed ND (6-Stop) View on Amazon View on B&H
While variable NDs are convenient for video, fixed ND filters are superior for long-exposure photography. The Breakthrough Photography X4 is widely regarded as the most color-neutral ND filter on the market. If youβre using your 24-105mm to blur waterfalls or smooth out ocean waves, this is the filter you want. It features a rugged, traction-heavy frame that is easy to grip even with wet hands. The SCHOTT Superwhite B270 glass ensures that the 24MP or 45MP resolution of your Canon R-series body isn’t compromised. Unlike variable NDs, there is absolutely zero risk of cross-polarization artifacts. Itβs also incredibly durable; Iβve dropped mine on rocks and it barely had a scratch. It is expensive for a single-stop filter, but the peace of mind and the 25-year warranty make it a “buy it once” product for serious landscape enthusiasts.

Freewell Magnetic VND Filter System View on Amazon View on B&H
If you hate fumbling with screw threads, the Freewell Magnetic system is a revelation. You screw a base ring onto your 24-105mm once, and then you can snap the ND filters on and off instantly. This is a lifesaver when light conditions are changing rapidly during a wedding or an outdoor event. The kit usually comes with multiple strengths or a VND configuration. You’ll notice that the magnets are incredibly strong; Iβve never had a filter fall off even when hiking through dense brush. The optical quality is very high, comparable to the NiSi. The main drawback is that you can’t easily use your original Canon lens hood while the magnetic base is attached, which is a common trade-off for magnetic systems. However, for sheer speed and convenience, itβs a game-changer for documentary-style shooters.

Frequently Asked Questions
What filter size does the Canon RF 24-105mm f/4L IS USM use?
The Canon RF 24-105mm f/4L IS USM uses a 77mm filter thread. This is a very common size for professional lenses, meaning you can often share filters with other glass like the RF 70-200mm f/2.8L. Always double-check the “ΓΈ77” mark on the front of your lens or the inside of the lens cap before purchasing. Using a step-up ring is possible, but it might prevent you from using the lens hood.
Will an ND filter cause vignetting at 24mm?
Vignetting can occur at the 24mm wide-angle setting if the filter frame is too thick. Most modern high-end filters, like the PolarPro or Breakthrough X4, are designed with ultra-slim profiles specifically to prevent this. However, if you stack a variable ND on top of a UV filter, you will almost certainly see dark corners. For the best results at 24mm, use a single slim-profile filter directly on the lens threads.
Do I need a 2-5 stop or a 6-9 stop ND filter?
For an f/4 lens like the RF 24-105mm, a 2-5 stop filter is usually sufficient for most daylight video scenarios to maintain a cinematic shutter speed. A 6-9 stop filter is generally reserved for extremely bright conditions (like snow or white sand) or for long-exposure photography where you want to turn moving water into a smooth mist. Most hybrid shooters find the 2-5 stop range to be the most versatile for daily use.
Can I use my lens hood with a variable ND filter?
In most cases, you cannot use the standard Canon lens hood with a variable ND filter. This is because VNDs are typically wider than the lens thread to prevent vignetting, and they often have adjustment levers that stick out. Some brands, like PolarPro, include a specialized cap or cover, but you will have to sacrifice the flare protection of the hood. Fixed ND filters usually allow for hood use without any issues.
Is it worth buying an expensive ND filter for an f/4 lens?
Yes, absolutely. The “L” in your lens stands for Luxury, and the glass is engineered for high resolution and contrast. Putting a cheap $20 filter in front of a $1,300 lens is like putting budget tires on a Ferrari; you significantly degrade the performance. A high-quality ND filter ensures that the sharpness and color rendition of your RF 24-105mm remain intact, preventing “soft” images and annoying color shifts in your final footage.
Final Verdict
For professional hybrid shooters using the RF 24-105mm f/4L, the PolarPro Peter McKinnon Edition II is the clear winner for its build and haptic stops. If you are a landscape purist, the Breakthrough X4 Fixed ND will give you the cleanest possible images. Hobbyists should look toward the NiSi True Color, as it offers the best balance of price and professional-grade color accuracy without breaking the bank.
