Best UV Filters for Yongnuo YN50mm F1.8
Protecting your Yongnuo YN50mm F1.8 is a bit of a balancing act. Since this “nifty fifty” is prized for its incredible affordability, you don’t want to spend more on glass protection than you did on the lens itself, yet poor-quality filters can easily degrade its surprisingly sharp output. I’ve tested dozens of filters on budget primes, and for most users, the Hoya NXT Plus hits the sweet spot. Let’s dive into which UV filters provide the best clarity without breaking the bank.

Best UV Filters for Yongnuo YN50mm F1.8: Detailed Reviews
Hoya NXT Plus UV View on Amazon View on B&H
The Hoya NXT Plus is my top recommendation because it doesn’t compromise the YN50mm’s sharpness. It features high-quality Schott glass and a 10-layer multicoating that boasts a 98% light transmission rate. One thing I love about this specific model is the waterproof top coat; if you’re shooting outdoors and a stray raindrop or fingerprint hits the glass, it wipes off effortlessly without leaving those annoying greasy streaks. The low-profile aluminum frame is well-machined, ensuring it won’t get stuck on your lens threads—a common issue with cheaper filters. While it costs a bit more than the absolute entry-level options, the ghosting resistance it provides when shooting into the sun is a massive upgrade over non-coated filters. It’s the perfect companion for the Yongnuo, offering professional-grade optics at a price that respects your budget.

Tiffen UV Protector View on Amazon View on B&H
Tiffen has been a staple in camera bags for decades, and their standard UV Protector is arguably the most popular filter ever made. It uses their proprietary ColorCore technology, which laminates the filter material between two pieces of optical glass. For the Yongnuo YN50mm, this filter provides rugged, physical protection against sand, dust, and accidental bumps. I’ve found that Tiffen filters are incredibly durable, though they do lack the fancy multicoatings of more expensive rivals. This means you might notice a slight increase in lens flare if you’re shooting directly toward a bright light source. However, for the price of a couple of lattes, you get a made-in-the-USA product that won’t perceptibly change the color balance of your shots. It’s the “set it and forget it” choice for photographers who want reliable peace of mind without overthinking the technical specs.

Amazon Basics UV Filter View on Amazon View on B&H
If you just bought the Yongnuo YN50mm and literally have ten dollars left in your pocket, the Amazon Basics UV filter is your savior. It is surprisingly well-constructed for the price, featuring a slim aluminum frame that prevents vignetting on full-frame sensors. I’ve used these as “disposable” protection in harsh environments like salt-spray beaches or mud runs where I don’t want to risk a $100 filter. The glass is clear and basic; you won’t see a drop in sharpness in typical daylight conditions. The drawback? It is highly prone to ghosting and internal reflections during night photography or high-contrast scenes. If you see “orbs” of light in your night shots, you’ll need to unscrew this. But for pure physical protection against a toddler’s sticky fingers or a thorny bush, it’s an unbeatable bargain that does exactly what it says on the tin.

B+W 010 UV-Haze MRC nano View on Amazon View on B&H
Putting a B+W filter on a Yongnuo lens is like putting premium tires on a budget sedan—it might seem like overkill, but the performance boost is real. The B+W 010 uses legendary Schott glass and a brass frame. Unlike aluminum, brass won’t “cold-weld” to your lens, making it much easier to remove after temperature changes. The MRC nano coating is incredibly slick, repelling water and oil better than any other filter I’ve handled. In side-by-side tests, the B+W maintains the micro-contrast of the lens better than the cheaper options, ensuring your F1.8 portraits remain crisp and punchy. If you plan on eventually upgrading to a Canon or Nikon 50mm, buying this 52mm filter now is a smart investment, as it will outlast the lens itself. It is the gold standard for photographers who refuse to put anything but the best glass in front of their sensors.

Urth UV Filter (Plus+) View on Amazon View on B&H
Urth (formerly Gobe) has made a name for itself by combining sleek design with environmental responsibility. Their “Plus+” range uses professional German SCHOTT glass, which is a significant step up from their entry-level line. In my experience, the Urth filters have some of the thinnest frames on the market, making them look very integrated into the Yongnuo’s plastic body. The 20-layer nano-coating does a fantastic job of cutting out haze and protecting the lens from scratches. Beyond the technical, for every filter purchased, Urth plants five trees in deforested areas—a mission I personally find very easy to support. While the threading can occasionally feel a little “tight” compared to the B+W brass, the optical quality is nearly indistinguishable in real-world shooting. It’s a stylish, high-performing alternative that feels modern and performs like a much more expensive piece of kit.

Frequently Asked Questions
Do I really need a UV filter for a cheap lens like the Yongnuo?
While the Yongnuo is affordable, a scratched front element will still render it useless. A UV filter acts as a cheap insurance policy. It’s much easier to replace a $20 filter than to buy a whole new lens. Plus, it keeps dust and moisture out of the lens barrel, which is particularly important since the YN50mm isn’t weather-sealed.
Will a UV filter make my photos look worse?
If you use a high-quality multicoated filter like the Hoya or B+W, you won’t notice any difference in sharpness or color. However, very cheap, non-coated filters can cause “ghosting” (duplicate light spots) and a loss of contrast when shooting toward the sun or bright indoor lights. Always choose a multicoated option if you’re worried about image quality.
What size filter does the Yongnuo YN50mm F1.8 take?
The most common version (for Canon EF mount) takes a 52mm filter. The Yongnuo 50mm F1.8 II also uses 52mm. However, the Nikon F-mount version typically uses a 58mm thread. Always check the number printed on the front of your lens next to the “ø” symbol to be 100% sure before ordering.
Can I leave the UV filter on all the time?
Yes, most photographers treat UV filters as permanent protection. They don’t significantly reduce the amount of light reaching your sensor (unlike ND filters), so there’s no need to take it off for low-light shots. The only time I recommend removing it is if you are seeing unwanted reflections when shooting bright city lights at night.
Is there a difference between a “UV” filter and a “Protector” filter?
Modern digital sensors already have UV-cut filters built-in, so the “UV” aspect is less important than it was in the film era. Today, UV filters and “Protector” filters are essentially the same thing: a clear piece of glass meant to shield your lens. Some “UV” filters may have a very slight warming effect, but it’s usually negligible.
Final Verdict
For most Yongnuo YN50mm owners, the Hoya NXT Plus is the clear winner—it offers the high-end coatings needed to maintain image quality without costing more than the lens itself. If you’re a student on a shoestring budget, the Tiffen or Amazon Basics filters provide excellent physical protection for a few dollars. Professionals or those planning to upgrade their kit soon should look at the B+W as a long-term investment in quality glass.
