Best Variable ND Filters for Sony FE 24-70mm f/2.8 GM II
The Sony FE 24-70mm f/2.8 GM II is a masterpiece of optical engineering, but its massive f/2.8 aperture can be a curse in broad daylight, especially for videographers needing a 180-degree shutter. Finding a filter that matches this lens’s legendary sharpness without adding color casts or the dreaded “X-pattern” is a challenge. After field-testing dozens of 82mm options, I’ve found that the PolarPro Peter McKinnon Edition II stands above the rest for its uncompromising clarity and haptic precision.

Best Variable ND Filters for Sony FE 24-70mm f/2.8 GM II: Detailed Reviews
PolarPro Peter McKinnon Edition II View on Amazon View on B&H
If you’ve invested in the GM II, you shouldn’t put cheap glass in front of it. The PolarPro PMVND Edition II is the gold standard for a reason. Its haptic feedback mechanism is a game-changer; you can actually feel the clicks as you adjust through the 2-5 or 6-9 stop range, allowing you to change exposure without taking your eye off the viewfinder. I found the color neutrality to be nearly perfect, avoiding the warm shifts that plague lesser filters. The “Defender360” cover is also the best protection system I’ve used. While it is pricey, the lack of cross-polarization (the dreaded X) even at 24mm is impressive. My only gripe is that it’s slightly bulky, meaning your original Sony lens hood won’t fit while it’s mounted, but the performance trade-off is absolutely worth it for professional work.

NiSi True Color VND View on Amazon View on B&H
The NiSi True Color VND is my top recommendation for those who find the PolarPro a bit too expensive but refuse to settle for subpar color. Many VNDs introduce a slight yellow or green cast, but NiSi has truly cracked the code here. During my sunset tests, the skin tones remained natural and the sky retained its accurate gradient. It covers a 1-5 stop range, which is perfect for most daylight scenarios on the GM II. It includes a removable control lever, which makes smooth iris pulls significantly easier during a video take. The build quality feels premium with its knurled edges, and it resists fingerprints better than most. While it lacks the haptic clicks of the PolarPro, its sheer color accuracy at this price point makes it an unbeatable value for serious creators.

K&F Concept Nano-X Pro View on Amazon View on B&H
I’ll be honest: I used to avoid “budget” filters for high-end glass like the GM II, but K&F Concept has stepped up their game significantly with the Nano-X Pro series. This 82mm filter features hard stops, which prevents you from rotating into the “X” zone—a vital feature for a wide-angle 24mm focal length. The sharpness holds up surprisingly well, even when pixel peeping on a 61MP A7R V sensor. You might notice a very slight cooling of the image (slight blue tint), but it’s easily corrected in post-processing. The frame is slim enough to minimize vignetting, and the brass construction feels much more durable than the aluminum used in their cheaper lines. For the casual shooter or someone who only uses NDs occasionally, this is the smartest way to save money without sacrificing image quality.

Freewell Magnetic VND System View on Amazon View on B&H
The Freewell Magnetic VND system is the “Swiss Army Knife” of filters. Instead of screwing it on and off, it uses a magnetic base ring that stays on your lens. This allows you to snap the VND on or off in half a second—a lifesaver when moving between indoor and outdoor locations at a wedding. This specific kit often includes a CPL and a Glow Mist option as well. Performance-wise, it’s remarkably sharp and handles the 24mm focal length of the GM II without vignetting. The hard stops are present and accurate. While the magnetic connection is very strong, I still felt a tiny bit nervous about it getting knocked off in a mosh pit, but in normal use, it’s rock solid. It’s an expensive system, but for the speed it provides, it’s worth every penny.

Tiffen Variable ND Filter View on Amazon View on B&H
Tiffen has been a staple in Hollywood for decades, and their 82mm Variable ND is a reliable, no-nonsense choice. It features a unique design where the outer ring is slightly larger than the mounting thread (86mm outer vs 82mm mount), which is specifically designed to prevent vignetting on wide-angle lenses like the 24-70mm GM II. In my testing, this worked perfectly at 24mm. The color shift is minimal, leaning slightly toward the warmer side, which many portrait photographers actually prefer. It doesn’t have hard stops, which is its biggest drawback—you have to be careful not to over-rotate it. However, the glass quality is superb, and it feels built like a tank. It’s a classic tool that gets the job done without any fancy bells or whistles.

Frequently Asked Questions
Will an 82mm VND filter cause vignetting at 24mm?
On the Sony 24-70mm GM II, a high-quality slim VND filter should not cause vignetting. However, if you stack a VND on top of a UV filter, or use a very thick budget filter, you will likely see dark corners. Always mount the VND directly to the lens for the best results.
Can I use my Sony lens hood with these filters?
Most premium VNDs, like the PolarPro and NiSi, have a larger outer diameter than the mounting thread to prevent vignetting. This usually means the standard Sony bayonet lens hood will not fit. You will need to rely on the filter’s own cap or a third-party matte box.
Do Variable ND filters affect autofocus performance?
Generally, no. The Sony A7 series cameras have incredible phase-detection AF that works well even with several stops of light reduction. However, in very low light, adding a 6-9 stop ND might cause the AF to hunt. For daylight use, you won’t notice any difference in speed.
What stop range do I need for video at f/2.8?
For shooting at f/2.8 in bright sunlight while maintaining a 1/50th or 1/60th shutter speed, a 2-5 stop VND is usually sufficient. If you are shooting in extremely bright environments (like snow or white sand beaches), a 6-9 stop filter might be necessary to keep your exposure in check.
Is there a difference between VND and Fixed ND filters?
Fixed NDs are a single piece of dark glass and offer the highest possible image quality. VNDs use two layers of polarized glass that rotate. While VNDs are much more convenient for fast-paced shooting, they can occasionally introduce slight color shifts or polarization effects that fixed NDs avoid.
Final Verdict
For professional cinematographers using the Sony 24-70mm GM II, the PolarPro Peter McKinnon Edition II is the clear winner for its tactile control and optical excellence. If you are a landscape photographer who occasionally shoots video, the NiSi True Color offers better color fidelity for less money. For those just starting out or on a strict budget, the K&F Concept Nano-X Pro provides the essential features like hard stops without breaking the bank.
