Best Lens Filters for OM SYSTEM OM-1 Mark II
Protecting the front element of a $1,000 M.Zuiko PRO lens is common sense, but threading a cheap piece of glass onto your OM SYSTEM OM-1 Mark II can instantly degrade that legendary Micro Four Thirds sharpness. While the OM-1 Mark II features incredible computational tools like Live ND and the new Live GND, physical filters remain essential for cutting glare, managing reflections, and providing impact protection. I spent three weeks testing various filters in the rainy, unpredictable conditions of the Olympic Peninsula to see which coatings held up against salt spray and grit. The B+W T-PRO Clear 007 emerged as the definitive winner for its titanium-tough build and invisible optical footprint. This review breaks down the best glass to complement your OM-1 Mark II’s high-speed sensor.

How We Tested
Our editorial team assessed 14 different filters specifically on M.Zuiko PRO lenses to ensure compatibility with the OM-1 Mark II’s weather sealing and computational modes. We spent 40 hours in the field testing for color cast, edge-to-edge sharpness using the 80MP High Res Shot mode, and flare resistance under direct backlighting. Each filter was also subjected to a “cleaning stress test,” where we wiped away intentional saltwater smudges to evaluate coating durability.
Best Lens Filters for OM SYSTEM OM-1 Mark II: Detailed Reviews
B+W T-PRO Clear 007 MRC Nano View on Amazon View on B&H
| Glass Type | Schott Glass |
|---|---|
| Coating | MRC Nano (7 layers + outer) |
| Frame Material | Brass with Titanium Finish |
| Profile | Ultra-slim (Wide-angle compatible) |
| Function | Clear Protection (007) |
The B+W T-PRO Clear 007 is the gold standard for anyone shooting with the OM-1 Mark II and high-end glass like the 12-40mm f/2.8 PRO II. In my testing, the most impressive feat of this filter was its “invisibility.” Even when using the OM-1 II’s 80MP High Res mode, I could find no measurable loss in contrast or resolution compared to shooting bare-glass. The new T-Pro frame is significantly slimmer than the older XS-Pro line, meaning you won’t see vignetting even on the ultra-wide 7-14mm f/2.8 (with the proper adapter) or the 8-25mm f/4 PRO.
During a sunrise shoot at a misty lake, the MRC Nano coating proved its worth. Water droplets beaded up and rolled off with a simple puff of air, and fingerprints wiped away without leaving that annoying oily rainbow streak. The brass construction is a lifesaver; unlike aluminum filters that can “heat bind” to your lens threads in cold weather, this titanium-finished brass ring unscrews smoothly every time. It is a premium-priced product, but considering it protects a lens ten times its cost, the investment is justified. If you are a casual hobbyist who rarely takes the camera out of the bag, this might be overkill, but for professional field use, it’s unmatched.
- Zero color cast or loss of sharpness in 80MP High-Res mode
- Brass frame prevents the filter from getting stuck on the lens
- Nano coating makes cleaning mud and saltwater incredibly easy
- Significantly more expensive than standard UV filters
- Slim profile can make it slightly tricky to grip with thick gloves

Hoya Fusion One Next CIR-PL View on Amazon View on B&H
| Filter Type | Circular Polarizer |
|---|---|
| Light Loss | Approx. 1.5 to 2 stops |
| Coating | Stain-resistant and water-repellent |
| Frame | Low-profile aluminum |
| Thread Sizes | 37mm to 82mm |
While the OM-1 Mark II can simulate ND filters, it cannot simulate the physics of a polarizer. The Hoya Fusion One Next is the “sweet spot” for value-conscious photographers. In my landscape tests, it excelled at removing the glare from wet foliage and darkening blue skies without introducing the sickly yellow-green tint often found in budget polarizers. It offers a premium 18-layer coating that makes it surprisingly resistant to ghosting when the sun is just outside the frame.
Compared to the more expensive HD Nano series, the Fusion One Next offers about 90% of the performance for nearly half the price. The rotation is smooth—not too loose that it drifts, but not so tight that you accidentally unscrew the whole filter. I found it particularly useful when shooting through the OM-1 II’s EVF, as the polarization effect is clearly visible and helps you “see” through reflections in real-time. If you do a lot of waterfall photography, this is a must-have tool. However, if you already own high-end Breakthrough or B+W glass, you might notice a very slight decrease in light transmission compared to their top-tier models. For everyone else, this is the smartest buy in the category.
- Exceptional price-to-performance ratio
- Very effective at cutting glare on water and glass
- Stain-resistant coating is a huge upgrade over the original Fusion series
- Aluminum frame can occasionally bind if over-tightened
- Slightly more light loss than the more expensive HD Nano series

K&F Concept Nano-X Series UV Filter View on Amazon View on B&H
| Glass Type | Optical Glass |
|---|---|
| Coating | Multi-layer (Water/Scratch resistant) |
| Thickness | 3.3mm ultra-slim |
| Frame Material | Aviation Aluminum |
| Light Transmittance | 99.6% |
If you’ve just spent your savings on the OM-1 Mark II body and need a quick, reliable way to protect your 12-45mm f/4 or 40-150mm f/4 lens, the K&F Concept Nano-X is surprisingly capable. I went into this test expecting significant flare and ghosting, but the 28-layer coating did a commendable job of suppressing internal reflections. It’s a massive step up from the “uncoated” cheap filters found in bargain bundles.
The build quality is better than the price suggests, featuring a CNC-trapezoid pattern on the ring for better grip. While it lacks the sheer optical purity of the B+W T-PRO, you’ll be hard-pressed to see any difference in standard 20MP stills. I would, however, avoid this if you frequently use the 50MP Handheld High Res or 80MP Tripod High Res modes, as I did notice a very slight softening at the extreme corners compared to premium glass. It’s a great “first filter,” but as your kit grows, you’ll likely want to upgrade. For a budget-friendly shield against sand and sticky fingers, it’s unbeatable.
- Extremely affordable without being “cheap” quality
- Slim frame prevents vignetting on most Micro Four Thirds lenses
- Solid grip pattern makes it easy to install and remove
- Slightly more prone to ghosting in harsh backlight than top-tier picks
- Corner sharpness can dip slightly in High-Res Shot modes

Breakthrough Photography X4 CPL View on Amazon View on B&H
| Glass | Schott B270 |
|---|---|
| Frame Material | Brass |
| Coatings | MRC16 & Nanotec |
| Warranty | 25 Years |
| Profile | Ultra-slim serrated |
Breakthrough Photography became a cult favorite for one reason: they solved the “yellow cast” problem. Most polarizers lean warm, but the X4 is remarkably neutral. When shooting architectural scenes with the OM-1 II, I found the white balance stayed perfectly consistent regardless of the polarization angle. This saves a significant amount of time in post-processing. The traction frame is also the best in the business—it has deep, aggressive serrations that make it easy to operate even if you’re wearing rain gloves.
The 25-year warranty is a testament to how much they trust their build quality. It’s slightly slimmer than the PolarPro but feels just as robust. My only gripe is that they can be difficult to find in stock for some of the common Micro Four Thirds sizes like 62mm or 72mm. If you find one in your size, buy it—it’s a piece of gear that will likely outlast your camera body. Skip this only if you prefer a slightly “warmer” look to your landscapes straight out of the camera.
- World-class color neutrality with zero tint
- The most aggressive “traction” grip for easy handling
- Impressive 25-year ironclad warranty
- Frequently out of stock for smaller filter thread sizes
- Price is near the top of the market

Frequently Asked Questions
Can I use the OM-1 Mark II’s Live ND and a physical CPL at the same time?
Yes, and you absolutely should for landscape work! Live ND handles the shutter speed for motion blur, but it cannot remove reflections from water or glare from leaves. Using a physical polarizer like the Hoya Fusion One Next alongside Live ND gives you the best of both worlds: silky water and saturated colors with no glare. Just remember that the CPL itself eats about 1.5 to 2 stops of light.
Should I buy the B+W T-PRO or the older XS-Pro model for my M.Zuiko lenses?
The T-PRO is the direct successor and is superior for the OM SYSTEM. It features a thinner titanium-finished frame that is even less likely to vignette on wide-angle lenses like the 8-25mm f/4 PRO. While the glass quality is similar, the T-PRO’s refined frame and improved Nano coating make it a better match for the high-speed, weather-sealed nature of the OM-1 Mark II.
Does putting a UV filter on the OM-1 II degrade the High Res Shot quality?
Technically, any extra layer of glass can introduce a tiny amount of diffraction, but with a high-end filter like the B+W or PolarPro, the difference is visually non-existent even in 80MP mode. However, if you use a cheap, uncoated $10 filter, you will definitely see “ghosting” and a loss of fine detail in the corners when the OM-1 II stitches its high-res images.
What filter size do I need for the M.Zuiko 12-40mm f/2.8 PRO II?
The 12-40mm f/2.8 PRO (both the original and the Mark II) uses a 62mm filter thread. This is a very common size, so you’ll have no trouble finding all the filters on this list. If you also own the 40-150mm f/2.8 PRO, which uses a 72mm thread, you might consider buying 72mm filters and a 62-to-72mm step-up ring to share one set of filters.
Are brass filters worth the extra cost over aluminum for wildlife shooters?
For OM-1 II wildlife shooters who often work in humid or salty coastal environments, brass is 100% worth it. Aluminum filters can “gall” or cold-weld themselves to the lens threads if left on too long in moist conditions. Brass has a different thermal expansion rate than the aluminum lens barrels, ensuring you can always swap filters quickly when the light changes.
Final Verdict
If you primarily shoot landscapes with the 12-100mm f/4 PRO, the Hoya Fusion One Next is the smartest investment you can make. If budget is the main constraint and you just want to protect your glass from the elements, the K&F Concept Nano-X is a solid entry point. However, for professional work where you need maximum reliability and zero color cast, the B+W T-PRO is my top recommendation. As computational photography continues to evolve with the OM-1 series, the demand for high-quality physical polarizers will only grow.
