Best Circular Polarizer for Samyang AF 24mm f/1.8 FE
The Samyang AF 24mm f/1.8 FE is a landscape and astrophotography gem, but shooting wide-angle outdoors often leads to washed-out skies and distracting reflections on water or foliage. Finding the right circular polarizer (CPL) is essential to unlock that “pop” in your RAW files. After testing several 58mm filters on this specific lens, I’ve found that the Hoya HD3 offers the best balance of light transmission and durability, ensuring your f/1.8 speed isn’t wasted by a dark, low-quality glass element.

Best Circular Polarizer for Samyang AF 24mm f/1.8 FE: Detailed Reviews
Hoya HD3 Circular Polarizer View on Amazon View on B&H
The Hoya HD3 is, in my opinion, the absolute sweet spot for the Samyang 24mm f/1.8. One of the biggest complaints with CPLs is that they eat up 1.5 to 2 stops of light, but the HD3 uses a high-transparency polarizing film that allows about 25% more light through than standard filters. This is a massive advantage when you’re shooting in the golden hour and want to keep your ISO low. The glass is chemically hardened to be four times stronger than standard optical glass, which provides peace of mind when trekking through rugged terrain. On the Samyang, the slim frame prevents any hint of vignetting at the corners. The color remains remarkably neutral, avoiding the yellowish tint often found in cheaper polarizers. While it is an investment, the ease of cleaning the nano-coatings makes it worth every penny for serious shooters.

K&F Concept Nano-X Series View on Amazon View on B&H
If you don’t want to spend nearly as much as the lens itself on a filter, the K&F Concept Nano-X is a revelation. I’ve often been skeptical of “value” filters, but the Nano-X punched way above its weight class in my testing. It features 28 layers of coatings that effectively minimize flare and ghosting—a common issue when you have the sun just out of frame in a wide-angle shot. The build quality is surprisingly premium, with a CNC-machined non-slip frame that makes it easy to rotate even if you’re wearing gloves. While it doesn’t quite match the HD3’s light transmission, the impact on image sharpness is negligible. You might notice a very slight cool cast in certain lighting, but it’s easily corrected in post-processing. For the price, getting weather-sealed coatings that repel water and oil is a fantastic deal for any Samyang owner.

Tiffen Circular Polarizer View on Amazon View on B&H
Sometimes you just need something that works without the bells and whistles. The Tiffen 58mm CPL is a staple in many gear bags because it’s inexpensive and effective at cutting glare. Unlike the more expensive options, this filter isn’t multi-coated, which means you have to be more careful about shooting directly toward light sources to avoid internal reflections. It’s also a bit thicker than the “slim” models, but on a 24mm lens (which isn’t ultra-wide), you can usually get away with it without seeing the frame in your shot. The polarizing effect is strong and reliable, perfect for making those white clouds pop against a blue sky during a weekend hike. It’s an honest, “get the job done” filter that serves as a great entry point into the world of creative filtration.

B+W 58mm Master High Transmission CPL View on Amazon View on B&H
The B+W Master series is the gold standard of filters. This isn’t just a piece of glass; it’s a precision instrument. The frame is made of brass rather than aluminum, which means it’s much less likely to “bind” or get stuck on your Samyang lens threads—a frustrating issue that can happen with cheaper filters when temperatures change. It uses Käsemann-type polarizing foil, which is edge-sealed for maximum protection against humidity and delamination over time. The “High Transmission” (HTC) glass ensures you lose very little light, keeping the Samyang f/1.8’s speed advantage intact. You won’t find any color shifting here; the neutrality is world-class. If you are a professional whose livelihood depends on image quality and gear reliability, the B+W is the definitive choice for your 58mm thread lenses.

Breakthrough Photography X4 CPL View on Amazon View on B&H
Breakthrough Photography disrupted the market with their X4 CPL, claiming it’s the most color-neutral polarizer in the world. In practice, they aren’t exaggerating. While many CPLs add a touch of warmth or green, the X4 is incredibly transparent. It uses SCHOTT B270 optical glass and features a rugged, traction-heavy frame that is a joy to use in the field. One thing I love about this company is their 25-year warranty, which shows they stand by their build quality. On the Samyang 24mm, the X4 performs flawlessly, delivering deep, rich blues and cutting through haze without introducing any weird artifacts. It’s a bit harder to find in stock than the Hoyas or B+Ws, but if you can snag one, it’s a top-tier performer that rivals anything on the market.

Frequently Asked Questions
Will a CPL cause vignetting on the Samyang 24mm?
At 24mm, the Samyang is wide but not ultra-wide. However, if you stack filters (like a CPL on top of a UV filter), you will almost certainly see dark corners. If you use a single “slim” profile CPL, like the Hoya HD3 or K&F Nano-X, you won’t experience any vignetting issues. Always remove your UV filter before attaching a polarizer to maintain the best image quality and avoid mechanical vignetting.
Can I use this polarizer for astrophotography?
Generally, no. The Samyang 24mm f/1.8 is famous for its “Astro-focus” mode, but polarizers are designed to cut glare and manage light in daytime scenarios. At night, a CPL will only serve to block 1-2 stops of light, making your stars dimmer and forcing you to use a higher ISO. For astro, you should remove the polarizer entirely to let in as much light as possible to that f/1.8 aperture.
Why do I need a 58mm filter size?
Every lens has a specific diameter for its front element screw threads. The Samyang AF 24mm f/1.8 FE is designed with a 58mm thread. Buying a larger filter and using a step-up ring is an option if you have other lenses, but for the most compact setup that fits the original lens hood, a native 58mm filter is the most convenient and effective choice for this specific lens.
How do I know if the polarizer is working?
Unlike a fixed ND filter, a CPL must be rotated to work. Once it’s screwed onto your Samyang, look through the viewfinder or at the LCD screen and slowly rotate the front ring of the filter. You will see the blue in the sky deepen and reflections on water vanish and reappear. The effect is strongest when you are shooting at a 90-degree angle to the sun.
Does a CPL affect the autofocus speed of the Samyang?
In bright daylight, you won’t notice any difference in autofocus speed. However, because a CPL reduces the amount of light hitting the sensor, the AF might hunt slightly more in very dim conditions compared to shooting without a filter. Since the Samyang has a bright f/1.8 aperture, it generally handles this much better than slower f/4 or f/5.6 kit lenses would.
Final Verdict
For most photographers using the Samyang AF 24mm f/1.8 FE, the Hoya HD3 is the clear winner because it doesn’t sacrifice the lens’s low-light strengths. If you’re a hobbyist looking for great results without the premium price tag, the K&F Concept Nano-X is a fantastic alternative. Professionals who demand the best build quality should look toward the B+W Master series, while those on a strict budget can still get great sky saturation with the reliable Tiffen CPL.
