Best ND Filter for Mitakon Zhongyi Speedmaster 50mm f/0.95
Shooting with the Mitakon Zhongyi Speedmaster 50mm f/0.95 is a surreal experience, but trying to use that massive aperture in broad daylight is a recipe for overexposed frustration. To keep your shutter speed under control while maintaining that signature “dreamy” bokeh, a high-quality ND filter is non-negotiable. I’ve spent years testing glass on fast primes, and for this “Dark Knight” lens, the PolarPro PMVND stands out as the gold standard for preserving color and sharpness.

Best ND Filter for Mitakon Zhongyi Speedmaster 50mm f/0.95: Detailed Reviews
PolarPro PMVND Signature Edition II View on Amazon View on B&H
The PolarPro PMVND Signature Edition II is, in my opinion, the perfect companion for the Mitakon 50mm f/0.95. When you’re shooting at f/0.95, you need absolute precision. This filter features haptic feedback, meaning you can feel the clicks as you adjust stops, allowing you to change exposure without taking your eye off the viewfinder. It uses fused silica glass which ensures that the Mitakon’s unique character isn’t muddied by soft edges or ugly color shifts. The 6-9 stop version is particularly useful for bright outdoor portraits where you want to keep that aperture wide open. While it is an investment, the lack of “cross-polarization” (that nasty X-pattern) even at higher densities makes it worth every penny. The Defender360 cover also provides incredible protection for the glass when it’s living in your bag.

K&F Concept Nano-X Variable ND View on Amazon View on B&H
If you want professional results without the “boutique” price tag, the K&F Concept Nano-X series is the sweet spot. It offers ND2 to ND32 reduction, which is generally enough for the Speedmaster unless you are shooting in direct desert sun. I’ve found the Nano-X coating to be surprisingly effective at repelling water and oil—crucial if you’re shooting street photography where fingerprints are inevitable. The frame is made of aviation-grade aluminum and is incredibly slim, preventing any vignetting on the 50mm’s relatively wide 67mm front element. While there is a very slight warm cast in certain lighting conditions, it’s easily corrected in post-processing. For the price of a nice dinner, you’re getting glass that holds up remarkably well against filters twice its price. It’s the “working man’s” filter for a very specialized lens.

Urth Variable ND (ND2-400) View on Amazon View on B&H
The Urth Variable ND (formerly Gobe) is the best entry-level option for those who just picked up a Mitakon and spent their last dime on the lens itself. This filter provides a huge range from 1 to 8.6 stops. While I wouldn’t recommend pushing it to the absolute ND400 limit due to some minor sharpness fall-off, it performs admirably in the middle of its range. You’ll notice the build quality is surprisingly tactile, and the company plants five trees for every purchase, which is a nice bonus. The main limitation is a slight decrease in contrast compared to the PolarPro, but when you’re shooting with the Speedmaster—a lens already known for its low-contrast, vintage look—this can actually be a stylistic advantage. It’s a reliable, honest piece of kit for someone learning the ropes of ultra-fast glass.

B+W 67mm XS-Pro MRC2 Nano 810 View on Amazon View on B&H
For those who find variable ND filters too compromising, the B+W XS-Pro 10-stop fixed filter is the ultimate choice. Variable filters use two layers of polarizing glass, which can sometimes mess with the bokeh shapes of the Speedmaster f/0.95. This B+W filter is a single solid piece of German-engineered glass. It provides a massive 10-stop reduction, which is perfect for long exposures or shooting wide open in harsh noon sunlight. The color neutrality is legendary—there is zero “purple fringe” or shift. The brass mount is also much less likely to jam on your lens threads than aluminum. While it’s less convenient than a variable filter (you have to unscrew it to focus in dark conditions), the image quality is objectively superior. This is for the photographer who wants to squeeze every ounce of performance out of the Mitakon’s optical design.

Tiffen Variable ND Filter View on Amazon View on B&H
The Tiffen Variable ND has been a staple in camera bags for a decade. What makes it unique for the Speedmaster is its slightly wider outer ring. This helps prevent vignetting, which can sometimes be an issue with thicker variable filters. The color reproduction is very “filmic”—it has a slightly warm, organic feel that complements the Mitakon’s vintage rendering beautifully. It’s built like a tank and can handle the rough-and-tumble of a wedding shoot or a travel vlog. You might see some minor cross-polarization if you push it to its extreme limits, but for 2-6 stops of light reduction, it’s incredibly consistent. I often recommend this to videographers because the rotation is smooth and has just the right amount of resistance for making mid-shot exposure adjustments without jarring the camera.

Frequently Asked Questions
What filter size does the Mitakon 50mm f/0.95 use?
The Mitakon Zhongyi Speedmaster 50mm f/0.95 (for Sony E, Nikon Z, and Canon RF mounts) uses a 67mm filter thread. This is a very common size, making it easy to find high-quality ND filters. Always double-check your specific version, as the older “Dark Knight” Mark I or some Leica M-mount variants can occasionally differ, but the modern Speedmaster III standard is 67mm.
Why do I need an ND filter for f/0.95?
Even with a 1/8000s shutter speed, f/0.95 lets in so much light that your photos will be completely blown out in daylight. An ND (Neutral Density) filter acts like sunglasses for your lens, reducing the light intensity without changing the color. This allows you to keep that shallow depth of field and beautiful bokeh even when the sun is at its brightest.
Is a variable ND better than a fixed ND?
Variable NDs are much more convenient because you can adjust the strength by turning the ring. However, they can occasionally cause an “X-pattern” on wide-angle lenses or slightly affect the shape of the bokeh. Fixed NDs offer the ultimate in optical purity but require you to carry multiple filters and swap them out as the light changes during your shoot.
Does an ND filter affect autofocus?
Since the Mitakon 50mm f/0.95 is a manual focus lens, the ND filter won’t affect autofocus. However, very dark filters (like 10-stops) can make the viewfinder or LCD screen dark, making it harder to focus manually. Most modern mirrorless cameras will compensate for this and brighten the display, but in low light, you might need to focus before putting the filter on.
What stop-range is best for the Speedmaster?
For shooting f/0.95 in bright sunlight, a 6-stop ND filter is the minimum I recommend. If you want to do long exposures or shoot in the middle of a bright summer day, a 10-stop filter or a variable ND that reaches ND400 (roughly 8.6 stops) is ideal. A 2 or 3-stop filter usually isn’t enough to tame the f/0.95 beast outdoors.
Final Verdict
If you’re a professional videographer or portrait artist, the PolarPro PMVND is the clear choice for its haptic feedback and reliability. Enthusiasts will find the K&F Nano-X provides 90% of the performance for half the price. For those who want the absolute cleanest image for fine art, the B+W fixed 10-stop is the way to go. No matter which you choose, don’t let your f/0.95 stay in the bag just because it’s sunny outside!
