Best UV Filter for Samyang AF 35mm f/1.8
The Samyang AF 35mm f/1.8 is a hidden gem for Sony shooters, offering razor-sharp optics in a tiny, weather-sealed package. However, that exposed front element is a magnet for dust and fingerprints, which can ruin your street photography sessions. I’ve tested dozens of glass options and found that the B+W 010 MRC Nano is the perfect companion for this specific lens. In this guide, I’ll help you choose a filter that preserves the Samyang’s impressive micro-contrast without adding unwanted flare.

Best UV Filter for Samyang AF 35mm f/1.8: Detailed Reviews
B+W 58mm 010 UV-Haze MRC Nano View on Amazon View on B&H
When you’re shooting with a lens as sharp as the Samyang AF 35mm f/1.8, the last thing you want is a cheap piece of glass degrading your resolution. The B+W 010 MRC Nano is widely considered the gold standard for a reason. Featuring Schott glass and a premium 16-layer Multi-Resistant Coating (MRC), it effectively eliminates ghosting and flare while remaining incredibly easy to clean. Raindrops and oil simply bead off the surface. I especially appreciate the brass ring construction; unlike aluminum filters that tend to “bind” or get stuck on lens threads, this brass frame glides on and off smoothly. While it is on the pricier side, the peace of mind it provides for the Samyang’s front element is unmatched. It’s a slim-profile design, so you won’t see any vignetting even if you stack a circular polarizer on top. It’s the ultimate “set it and forget it” protection.

Hoya 58mm NXT Plus UV View on Amazon View on B&H
Hoya has a reputation for delivering high-quality optics at a price that doesn’t hurt the wallet, and the NXT Plus is no exception. This filter features a waterproof top coat which is a massive upgrade over the standard HMC line. If you’re out shooting street photography in light drizzle, you’ll find that cleaning this filter is significantly easier than cheaper alternatives. The 58mm thread size fits the Samyang perfectly, and the aluminum frame is milled with a low profile to prevent any corner shading. I’ve found that the light transmission on this filter is remarkably high (over 98%), meaning you won’t notice any loss in exposure or color shifts. While it doesn’t have the heavy, luxury feel of the B+W brass, it’s a rugged, dependable piece of kit. For the enthusiast who wants to protect their lens without spending nearly a third of the lens’s cost on a filter, this is the sweet spot.

K&F Concept 58mm MCUV Nano-K View on Amazon View on B&H
If you’ve just spent your budget on the Samyang lens and a Sony body, you might be looking for a low-cost way to keep that glass safe. The K&F Concept Nano-K series is surprisingly good for the price. Unlike the “no-name” filters often found in bundles, K&F uses genuine optical glass with 18 layers of multi-coating. In my experience, it handles basic reflections well, though it may show slightly more flare than the B+W when shooting directly into a sunset. The frame is made of aviation-grade aluminum and is incredibly thin, which is great for the compact Samyang 35mm. The main limitation is that the coating isn’t quite as “slick” as the more expensive Nano coatings, so fingerprints might take an extra wipe to remove. However, for sheer physical protection against scratches and sand, it performs exactly as it should without breaking the bank.

Breakthrough Photography 58mm X4 UV View on Amazon View on B&H
The Breakthrough Photography X4 is for the perfectionist who demands the absolute best transmission. They claim it is the world’s sharpest UV filter, and while that’s hard to verify without a lab, the real-world results are stunning. It uses SCHOTT Superwhite B270 glass and features a unique “traction” frame. This knurled texture makes it incredibly easy to grip, even when wearing gloves—a feature I’ve come to love during cold morning shoots. It’s also incredibly color-neutral; many UV filters have a slight warm or cool cast, but the X4 is virtually invisible to your camera’s sensor. The weather-sealing on the Samyang 35mm f/1.8 is already good, but adding a high-end filter like the X4 creates a total front seal that protects against the finest salt spray or dust. It’s a luxury item, but it’s built to last a lifetime and backed by a 25-year warranty.

Zeiss 58mm T* UV Filter View on Amazon View on B&H
If you’re a fan of the “Zeiss Look” and want to maintain that specific rendering on your Samyang lens, the Zeiss T* UV filter is a fantastic choice. This filter uses the same legendary T* anti-reflective coating found on high-end Zeiss lenses. I’ve found that it produces a very clean, high-contrast image, especially when shooting in backlit situations where other filters might struggle with internal reflections. The build quality is exceptional, featuring a slim mount that ensures no vignetting on the 35mm focal length. While Samyang and Zeiss are different manufacturers, the rendering of the T* coating actually complements the Samyang’s sharp, modern look quite well. It’s slightly more expensive than the Hoya but cheaper than the Breakthrough X4, making it a solid mid-to-high-tier option for those who value brand heritage and proven coating technology.

Frequently Asked Questions
Does the Samyang 35mm f/1.8 need a UV filter for weather sealing?
While the Samyang AF 35mm f/1.8 features weather sealing at the mount and several internal points, the front element is often the most vulnerable spot. Adding a high-quality UV filter completes the “seal” by preventing moisture or dust from entering through the front lens group movemement. It’s highly recommended if you plan on shooting in humid or dusty environments to fully protect the internal electronics of the lens.
Will a UV filter reduce the sharpness of my images?
If you use a high-quality multi-coated filter like the B+W or Hoya options mentioned above, you will not notice any visible drop in sharpness. Modern optical glass is incredibly precise. However, cheap, non-coated filters can cause light diffraction, leading to “soft” images and loss of contrast. I always suggest that if you can’t afford a decent filter, it’s better to use no filter at all and just rely on the lens hood.
What is the difference between UV and Protector filters?
UV filters are designed to block ultraviolet light, which could cause a blueish haze in film photography. On modern digital sensors, which already have UV filters built-in, a UV filter primarily serves as a physical “protector.” Some brands sell “Protector” filters which are just clear glass. For all practical purposes, they serve the same role on a digital camera: keeping your expensive Samyang lens element safe from scratches and impact.
Can I still use my original Samyang lens cap with these filters?
Yes, all the filters listed here—including the slim-profile ones—feature front threads. This means you can easily snap your original 58mm Samyang lens cap directly onto the front of the filter. You can also stack other filters, like a Circular Polarizer or an ND filter, though I recommend removing the UV filter first if you’re stacking to minimize the risk of vignetting or image degradation.
How often should I clean my UV filter?
You should only clean your filter when you see visible smudges, dust, or water spots. Over-cleaning can actually lead to micro-scratches in the coating over time. I find it’s best to use a rocket blower first to remove loose grit, followed by a clean microfiber cloth or a LensPen. The Nano coatings on the B+W and Breakthrough filters make this process much faster as they resist oils and fingerprints better than standard glass.
Final Verdict
For most Samyang AF 35mm f/1.8 owners, the B+W 010 MRC Nano is the smartest investment; its brass ring and elite coating ensure your lens performs perfectly for years. If you’re on a tighter budget, the Hoya NXT Plus offers nearly identical optical performance with a slightly less premium frame. For casual weekend shooters, the K&F Concept provides adequate protection. Whichever you choose, ensure it’s a 58mm slim-frame model to keep your Sony setup compact and vignette-free.
