Best UV Filter for Mitakon Zhongyi Lens
Mitakon Zhongyi lenses, particularly the legendary Speedmaster series, are beloved for their ultra-fast apertures and unique character. However, these manual focus gems often lack robust weather sealing, making the front element vulnerable to dust and scratches. I’ve spent years shooting wide open at f/0.95, and I’ve learned that a subpar filter can ruin that creamy bokeh with nasty ghosting. For most Mitakon users, the Hoya NXT Plus offers the perfect balance of optical clarity and durable protection without breaking the bank.

Best UV Filter for Mitakon Zhongyi Lens: Detailed Reviews
Hoya NXT Plus UV View on Amazon View on B&H
The Hoya NXT Plus UV is my go-to recommendation for Mitakon lenses like the 50mm f/0.95 III. When you’re shooting with such a fast aperture, any internal reflections between the sensor and the filter glass can create distracting “ghost” artifacts. Hoya addresses this with a 10-layer HMC multicoating that boasts a 98% transmission rate. In my experience, it maintains the lens’s native contrast beautifully, even when shooting into backlit scenes. The waterproof top coat is a lifesaver; fingerprints and raindrops wipe off with a single pass of a microfiber cloth. It features a low-profile aluminum frame that prevents vignetting on wider Mitakon glass, such as the 20mm f/2 Super Macro. While some pros prefer brass frames, Hoyaβs precision milling ensures this won’t get stuck on your threads. Itβs a high-performance filter that respects the optical integrity of your “Speedmaster” glass.

B+W 010 UV-Haze MRC View on Amazon View on B&H
B+W is a name synonymous with quality, and their 010 UV-Haze with Multi-Resistant Coating (MRC) is a masterpiece of German engineering. What sets this apart for your Mitakon lens is the brass frame. Unlike aluminum, brass is less likely to “bind” or cross-thread, which is vital if you frequently swap filters in the field. The SCHOTT glass used here is world-class, ensuring that your f/0.95 bokeh stays smooth and free of “onion ring” textures caused by surface imperfections. The MRC coating is incredibly tough, resisting scratches and repelling dust effectively. I’ve found that in extremely harsh lighting, B+W filters handle flare slightly better than the Hoya, though the difference is subtle. The only downside is the price premium for the brass construction, but considering the investment youβve made in Mitakonβs fast primes, this filter provides peace of mind that lasts for decades.

Tiffen UV Protector View on Amazon View on B&H
If you’ve just spent your entire gear budget on a Mitakon 35mm f/0.95 and only have a few dollars left, the Tiffen UV Protector is a functional stop-gap. Itβs a no-frills piece of glass designed primarily for physical protection. It will stop a stray branch or a fingerprint from touching your precious front element. However, unlike the Hoya or B+W, this filter lacks advanced multicoating. This means you might notice a slight drop in contrast when shooting directly into the sun, and ghosting can become an issue during night photography. I often keep one of these in my bag as a “disposable” filter for shooting in messy environments like color runs or salt-spray heavy beaches. Itβs better than no protection at all, but for a lens with the optical character of a Mitakon, youβll eventually want to upgrade to something with better anti-reflective properties.

Breakthrough Photography X4 UV View on Amazon View on B&H
The Breakthrough Photography X4 UV is widely considered the sharpest UV filter on the market today. It uses SCHOTT B270 glass and features a state-of-the-art MRC16 coating layer. For Mitakon users, the real draw here is the 99.4% light transmission rate. When you’re using a Speedmaster to suck in every available photon in low-light environments, you don’t want a filter that eats your light. The frame is exceptionally well-built with deep knurling, making it easy to remove even when wearing gloves. I particularly appreciate that Breakthrough stands behind their products with a 25-year warranty. It is significantly more expensive than the Hoya, but the color neutrality is impeccable. If you are using a high-resolution sensor like the Sony A7R V with your Mitakon glass, this is the only filter that truly disappears from the optical path, leaving your images tack-sharp and flare-free.

Marumi Super DHG UV View on Amazon View on B&H
Marumi is the “dark horse” of the filter world, often outperforming much more expensive brands in independent lab tests. The Super DHG UV is an excellent middle-ground option that offers high-end coatings at a very reasonable price. It features a satin-finish frame designed to minimize internal reflections, which pairs perfectly with the high-gloss elements often found inside Mitakon lenses. The glass is thin but durable, and the oil-repellent coating works remarkably well against greasy smudge marks. I find Marumi filters to be particularly consistent; you never get a “bad” copy. Itβs an ideal choice for the Mitakon 65mm f/1.4 for Fuji GFX, where you need a large 72mm filter that won’t degrade the medium-format resolving power. While it lacks the brand prestige of B+W, the performance-to-price ratio is almost unbeatable for the serious hobbyist.

Frequently Asked Questions
Will a UV filter affect the f/0.95 bokeh?
If you use a high-quality filter like the Hoya NXT Plus or Breakthrough X4, you won’t see any impact on your bokeh. Low-quality, uncoated filters, however, can introduce “onion rings” or micro-contrast loss. Because Mitakon lenses are prized for their unique rendering, using a premium filter ensures that the dreamy background blur remains undisturbed while protecting the lens from the elements.
What is the filter size for the Mitakon 50mm f/0.95?
The Mitakon Zhongyi Speedmaster 50mm f/0.95 (Version III) typically uses a 67mm filter thread. However, older versions or the 50mm f/0.95 for Canon EF use different sizes. Always check the front of your lens barrel or the inside of the lens cap for the “ΓΈ” symbol followed by a numberβthat is your specific filter thread size in millimeters.
Do I really need a UV filter for a manual lens?
While UV light doesn’t affect digital sensors like it did film, the primary purpose today is physical protection. Mitakon lenses are often heavy and feature protruding front glass. A UV filter acts as a sacrificial layer. If you bump your lens against a table, itβs much cheaper to replace a $50 Hoya filter than to repair the front element of a Speedmaster lens.
Does a UV filter cause vignetting on Mitakon lenses?
Mitakonβs wider lenses, like the 20mm f/2 or 35mm f/0.95, can be sensitive to thick filter frames. To avoid dark corners (vignetting), always choose a “Slim” or “Low Profile” frame. All the recommendations on this list, except for the basic Tiffen, feature slim designs specifically engineered to work with wide-angle and fast-aperture lenses without cutting into the frame.
Can I stack a Polarizer over my UV filter?
You can, but I don’t recommend it. Stacking two filters increases the distance between the lens and the glass, which significantly increases the risk of vignetting and flare. If you need to use a Circular Polarizer (CPL) or an ND filter for a specific shot, itβs best practice to remove your UV filter first to maintain the highest possible image quality.
Final Verdict
For the vast majority of Mitakon Zhongyi owners, the Hoya NXT Plus UV is the smartest investment; it offers professional-grade coatings that preserve the lens’s character at a fair price. If you frequently shoot in harsh environments, the B+W 010’s brass frame is worth the extra cost. For those demanding absolute perfection on high-res bodies, the Breakthrough X4 is the ultimate choice. Whichever you choose, getting a filter on that lens today is a move your future self will thank you for.
