Best Lens Filter for Mitakon Zhongyi Speedmaster 50mm f/0.95
Owning the Mitakon Zhongyi Speedmaster 50mm f/0.95 is like having a superpower for low light and “bokehlicious” portraits, but that massive f/0.95 aperture presents a unique challenge: shooting in daylight without blowing out your highlights. Whether you’re trying to manage exposure or protect that specialized glass, choosing the right filter is critical. After putting several options through their paces, I’ve found that a high-quality Variable ND is the absolute best companion for this lens to maintain that dreamy, wide-open look.

Best Lens Filters for Mitakon Speedmaster 50mm f/0.95: Detailed Reviews
PolarPro PMVND Signature Edition II View on Amazon View on B&H
The Mitakon f/0.95 is a light bucket, and the PolarPro PMVND Signature Edition II is the best way to tame it. When shooting at f/0.95 in broad daylight, even a 1/8000 shutter speed often isn’t enough. This filter provides 2-5 or 6-9 stops of light reduction with zero cross-polarization (the dreaded “X-pattern”). I found the haptic feedback—a subtle click at each stop—incredibly useful when I didn’t want to take my eye off the viewfinder. The color accuracy is second to none; there is no annoying yellow or blue shift that you often see in cheaper NDs. It’s built like a tank with fused quartz glass, ensuring that your $600+ lens’s sharpness isn’t compromised. The only downside is the price, but if you’re serious about the “Speedmaster” look in the sun, this is the gold standard.

K&F Concept Nano-X True Color View on Amazon View on B&H
If you can’t justify spending nearly half the cost of the lens on a filter, the K&F Concept Nano-X True Color is a revelation. Traditionally, budget VNDs suffer from a heavy green tint, but K&F has mostly solved this with their “True Color” series. Using this on the Speedmaster 50mm f/0.95 III, I noticed it maintains the lens’s natural character while allowing for that razor-thin depth of field in bright conditions. The 28 multi-layer coatings help significantly with ghosting and flares—a common issue with the Mitakon’s older optical designs. The frame is surprisingly slim, which is a big plus because the Speedmaster is already a heavy, chunky lens. It doesn’t have the haptic clicks of the PolarPro, and you might see very slight vignetting at the maximum setting, but for the price, it’s an unbeatable value proposition.

Hoya NXT Plus UV Filter View on Amazon View on B&H
Sometimes you don’t need to cut light; you just need to protect that massive 67mm front element from dust, fingerprints, and the occasional bump. The Hoya NXT Plus is my go-to “set it and forget it” filter for the Mitakon. It’s incredibly affordable but doesn’t feel cheap. The 10 layers of Hoya Multi-Coating (HMC) are vital here because the Speedmaster 50mm is already prone to internal reflections; you don’t want a low-quality UV filter adding more flare. The glass is 98% transparent, meaning it won’t affect your exposure or image quality in any perceptible way. It’s a simple, honest piece of equipment. While it won’t help you shoot at f/0.95 in the sun, it’s essential for street photography where you might be changing lenses quickly and don’t want to worry about scratching the Mitakon’s front element.

B+W 010 UV-Haze MRC nano (T-Pro) View on Amazon View on B&H
If you want the absolute best German engineering for your lens, the B+W T-Pro series is the answer. The Speedmaster is a dense, heavy lens, and it deserves a filter with a brass frame that won’t bind or get stuck. The MRC nano coating is legendary for how easily it sheds water and oil; if you get a fingerprint on this while shooting a wedding, a quick wipe with a microfiber cloth cleans it instantly without smearing. I find this filter particularly good for the Mitakon because it is ultra-slim, ensuring that the filter itself doesn’t cause any mechanical vignetting on top of the lens’s natural f/0.95 light falloff. It’s an investment in the longevity of your gear. While expensive for “just” a UV filter, the peace of mind and ease of cleaning make it a favorite for working professionals.

Tiffen Black Pro-Mist 1/4 View on Amazon View on B&H
The Mitakon 50mm f/0.95 is already known for its “glow” and soft rendering wide open. If you want to lean into that “vintage cinema” look, the Tiffen Black Pro-Mist 1/4 is a magical addition. It takes the sharp edges off digital sensors and adds a beautiful halation to light sources. When I use this for night portraits at f/0.95, the streetlights bloom in a way that looks like 35mm film. It also softens skin textures slightly, which is great for portraiture where the lens’s narrow depth of field might otherwise make skin imperfections pop. It’s not a filter you’ll leave on every day, but for stylized video work or romantic portraits, it complements the Mitakon’s optical character perfectly. Be careful with the 1/2 strength, as it can be a bit “too much” on an already soft lens like this.

Frequently Asked Questions
What is the filter thread size for the Mitakon Speedmaster 50mm f/0.95?
The most common version, the Mitakon Zhongyi Speedmaster 50mm f/0.95 III (for Sony E, Canon RF, and Nikon Z), uses a 67mm filter thread. However, older versions like the Mark II for Sony E used a smaller 58mm thread. It is vital to check the markings on the front of your specific lens barrel or the inside of your lens cap before purchasing to ensure a perfect fit.
Do I really need an ND filter for an f/0.95 lens?
Yes, absolutely. If you want to shoot at f/0.95 in daylight, you will almost certainly hit your camera’s maximum shutter speed (usually 1/4000 or 1/8000) and still have an overexposed image. A Variable ND filter allows you to block enough light to keep that aperture wide open, giving you the shallow depth of field and beautiful bokeh that you bought the lens for in the first place.
Will a filter cause vignetting on this lens?
The Speedmaster 50mm f/0.95 naturally has heavy vignetting when shot wide open. Adding a thick or poorly designed filter can worsen this effect, creating “mechanical vignetting” where the filter frame itself blocks light. To avoid this, always look for “slim” or “thin” profile filters. All the options recommended in this guide are chosen specifically because they have slim frames that minimize any additional corner shading.
Does an ND filter affect the bokeh quality?
A high-quality ND filter like the PolarPro or K&F Nano-X will not noticeably affect the shape or smoothness of your bokeh. However, very cheap, non-coated filters can introduce internal reflections or “ghosting” within the bokeh balls. Because the Speedmaster’s bokeh is its main selling point, I highly recommend investing in a filter with quality multi-coatings to preserve the lens’s unique optical “character” and creamy background blur.
Can I use a lens hood with these filters?
The Mitakon 50mm f/0.95 III comes with a clip-on or screw-in hood depending on the batch. Most standard UV filters will allow you to attach the hood over them. However, Variable ND filters are often slightly wider than the thread size to prevent vignetting, which can sometimes interfere with the original lens hood. In those cases, you may need to choose between the hood or the VND filter during your shoot.
Final Verdict
If you are a professional videographer or a portrait photographer who lives for that f/0.95 look, the PolarPro PMVND is the best investment you can make for this lens. For those on a tighter budget who still want to shoot wide open in the sun, the K&F Concept Nano-X offers incredible “true color” performance. Finally, if you just need to protect your glass from the elements, the Hoya NXT Plus is a reliable, no-nonsense choice that won’t degrade your image quality.
