Best UV Filter for Mitakon Speedmaster 50mm f/0.95
The Mitakon Speedmaster 50mm f/0.95 is a masterpiece of light-gathering, but its massive front element is a magnet for dust and fingerprints. When you’re shooting wide open at f/0.95, any optical imperfection is magnified, making a high-quality UV filter essential rather than optional. I’ve tested dozens of filters on fast primes, and for this specific lens, the B+W Master 010 stands out as the gold standard for preserving that dreamy bokeh and legendary sharpness without introducing ghosting.

Best UV Filter for Mitakon Speedmaster 50mm f/0.95: Detailed Reviews
B+W 67mm Master 010 UV MRC Nano View on Amazon View on B&H
If you have spent the money on a lens as unique as the Speedmaster, you shouldn’t compromise on the glass sitting in front of it. The B+W Master 010 uses premium Schott glass, ensuring that the light transmission remains nearly perfect. What I love most about the Master series is the brass traction frame; unlike aluminum filters that can “bind” or get stuck on your lens threads, the brass ring on this B+W glides on smoothly and stays put. The MRC Nano coating is a lifesaver when shooting in messy environments, as it repels water and oil like magic. While it is certainly on the pricier side, it is the only filter I truly trust not to introduce unwanted flaring when I’m shooting directly into a light source at f/0.95. It’s a slim profile too, so no vignetting issues here.

Hoya 67mm NXT Plus UV Filter View on Amazon View on B&H
The Hoya NXT Plus is the “sweet spot” of UV filters. It offers significantly better performance than entry-level glass without hitting the triple-digit price tag of premium German brands. I’ve found that Hoya’s HMC (Hoya Multi-Coated) technology does an excellent job of minimizing reflections—a critical factor when you’re using a lens with an f/0.95 aperture that is already prone to some internal flare. This filter features a waterproof top coat that makes it much easier to wipe away raindrops or stray fingerprints in the field. The aluminum frame is low-profile and lightweight, fitting perfectly on the Mitakon’s 67mm thread. While it might not feel as “heavy-duty” as a brass B+W, its optical performance is remarkably close. For most photographers, this is the most sensible choice for balancing protection and image quality.

K&F Concept 67mm Nano-K UV Filter View on Amazon View on B&H
If you just bought the Mitakon and your wallet is feeling a bit thin, the K&F Concept Nano-K series is a surprisingly competent placeholder. For a budget filter, it’s impressively thin, which is great for maintaining the sleek look of your Speedmaster. It features 18 layers of multi-coating, which is rare at this price point. In my testing, it provides solid protection against scratches and dust. However, be aware that in challenging backlit situations, you might notice a slight increase in lens flare compared to a Hoya or B+W. The glass is good, but not “perfectly” neutral. It is perfect for those who primarily want a “sacrificial” layer of glass to protect their lens during street photography. It’s a great way to get peace of mind without spending a fortune, just be prepared for a bit more cleaning effort than the nano-coated options.

Breakthrough Photography 67mm X4 UV Filter View on Amazon View on B&H
The Breakthrough Photography X4 is widely considered the most color-neutral UV filter on the market. When you’re shooting with a f/0.95 lens, you want every bit of light to hit the sensor accurately. This filter boasts a staggering 99.4% light transmission, ensuring no loss in exposure. The build quality is phenomenal; it uses a knurled “traction” frame that makes it incredibly easy to grip, even if you’re wearing gloves or shooting in the rain. It’s made of brass, just like the B+W, so it won’t bind to your lens. Breakthrough is so confident in the X4 that they offer a 25-year warranty, which is almost unheard of in the industry. If you want the absolute best optical performance possible for your 50mm Speedmaster and you don’t mind paying a premium for it, the X4 is the ultimate choice.

Marumi 67mm Exus UV Filter View on Amazon View on B&H
The Marumi Exus is a hidden gem from Japan that many photographers overlook. Its standout feature is an anti-static coating that prevents dust from clinging to the glass—a major plus for the Mitakon 50mm f/0.95, as dust particles on the front element can sometimes show up as “bokeh balls” or artifacts when shooting wide open. The glass is high-grade and the frame is designed with a blackened outer rim to reduce internal reflections. In my use, I’ve found it to be exceptionally easy to clean; a quick puff of air usually does the trick. It’s also very thin, which ensures it won’t interfere with the lens cap or create vignetting. If you frequently find yourself shooting in dry, dusty locations, the Marumi Exus will save you a lot of time in post-production by keeping your shots clean from the start.

Frequently Asked Questions
Will a UV filter cause vignetting on the 50mm f/0.95?
Generally, no. Since 50mm is a standard focal length, it is not wide enough to be affected by the thickness of a standard filter frame. However, choosing a slim-profile filter like the B+W Master or Hoya NXT Plus is always a good practice to ensure that there is absolutely no interference with the lens’s field of view or the attachment of the lens hood.
Does a UV filter affect the bokeh of the Speedmaster?
If you use a high-quality multi-coated filter, the impact on bokeh is negligible. However, a cheap, non-coated filter can introduce “onion rings” or flare artifacts into your out-of-focus highlights. Because the Mitakon f/0.95 is famous for its smooth bokeh, I highly recommend investing in a premium filter like the B+W or Breakthrough X4 to preserve that unique look.
What is the filter thread size for the Mitakon Speedmaster 50mm f/0.95?
The standard filter thread size for the Mitakon Speedmaster 50mm f/0.95 (Version II and III for Sony E, Nikon Z, and Canon RF) is 67mm. It is always wise to double-check the front of your specific lens barrel, as some very early versions or different mounts might have variations, though 67mm is the industry standard for this specific model.
Do I really need a UV filter for mirrorless cameras?
Modern digital sensors have built-in UV and IR filters, so a UV filter won’t “improve” the image quality in the traditional sense. However, for a lens with a large front element like the Speedmaster, the primary purpose is physical protection. It is much cheaper and easier to replace a $60 filter than it is to repair a scratch on f/0.95 optics.
Can I stack a UV filter with a CPL or ND filter?
Technically yes, but it is not recommended on a lens this fast. Stacking multiple layers of glass increases the risk of internal reflections and ghosting, especially when shooting wide open. If you need to use an ND filter for daytime shooting at f/0.95, I recommend removing the UV filter first to maintain the highest possible image contrast and clarity.
Final Verdict
For the Mitakon Speedmaster 50mm f/0.95, the B+W Master 010 is the clear winner for professionals who want zero compromises. If you are a hobbyist looking for a reliable balance of price and performance, the Hoya NXT Plus is an excellent secondary choice. For those primarily concerned with physical protection on a budget, the K&F Concept will do the job, but remember that the higher-end glass truly lets this lens shine.
