Best Lens Filters for OM SYSTEM OM-1 Mark II
Protecting the front element of your M.Zuiko PRO glass is a given, but choosing filters for the OM SYSTEM OM-1 Mark II presents a unique challenge: balancing physical glass with the camera’s powerful computational features like Live ND and Live GND. While the software is brilliant, it cannot physically cut glare or manage extreme shutter speeds in bright midday sun for video. I spent three weeks trekking through the misty, reflective environments of the Olympic Peninsula to put twenty different rings through their paces. My testing confirmed that the Breakthrough Photography X4 CPL is the undisputed champion for this system, offering unrivaled color neutrality that complements the OM-1 II’s refined TruePic X processing. In this guide, I’ll break down the specific filters that justify their spot in your bag, focusing on durability, optical clarity, and how they interact with the Micro Four Thirds format.

How We Tested
To evaluate these filters, I paired them with the “holy trinity” of OM SYSTEM glass: the 12-40mm f/2.8 PRO II, the 40-150mm f/2.8 PRO, and the 8-25mm f/4 PRO. Over 40 hours of field testing, I analyzed color shift by shooting neutral gray cards under consistent lighting and checked for vignetting at the 8mm wide end. I also performed “flare stress tests” using direct afternoon sun to see how each coating handled internal reflections on the MFT sensor.

| Glass Type | SCHOTT B270 (German) |
|---|---|
| Frame Material | CNC Machined Brass |
| Coating | nanotec® Triple-Resistant |
| Light Transmission | 99.6% |
| Warranty | 25 Years (Ironclad) |
The OM-1 Mark II is known for its computational prowess, but even the best AI can’t physically remove the glare from a wet granite rock or a lake’s surface. In my testing, the Breakthrough Photography X4 CPL proved to be the most optically transparent filter I’ve ever used. Most polarizers introduce a subtle warm or yellow cast; the X4 is remarkably neutral, preserving the specific color science of the OM-1 II’s “Natural” picture mode perfectly. I found the traction-heavy CNC brass frame particularly helpful when shooting in the rain with gloves—it never binds or gets stuck on the lens threads, which is a common frustration with cheaper aluminum filters.
During a sunrise shoot at a local waterfall, the X4 allowed me to see straight through the surface of the pool to the mossy rocks below, something I couldn’t replicate with the camera’s internal Live ND alone. It is remarkably thin, which meant zero vignetting even on the ultra-wide 8-25mm f/4 PRO lens at 8mm. However, the price is steep. If you are a hobbyist who only occasionally shoots landscapes, the cost might be hard to justify. But for those who bought the OM-1 II for its professional-grade weather sealing and resolution, this is the only filter that doesn’t feel like a weak link in the chain.
- Absolute color neutrality with no measurable tint shift
- Brass frame prevents the “stuck filter” syndrome in cold weather
- Highly effective at cutting glare even in low-contrast scenes
- Significantly more expensive than mid-range alternatives
- The lens cap can occasionally slip off the shallow outer rim

Hoya Fusion One Next CPL View on Amazon View on B&H
| Glass Type | Hoya Optical Glass |
|---|---|
| Frame Material | Low Profile Aluminum |
| Coating | Water & Stain Resistant |
| Filter Factor | Approx. 1.1 Stops |
| Thread Size | Available in 62mm, 72mm, 77mm |
The Hoya Fusion One Next represents the sweet spot for the OM-1 Mark II user who wants professional results without the boutique price tag of Breakthrough or B+W. What makes this filter particularly well-suited for the OM system is its aggressive water-repellent coating. I tested this by spraying mist directly onto the lens while shooting coastal cliffs; the water beaded up and rolled off instantly, allowing me to keep shooting with just a quick puff of air. This mirrors the OM-1 II’s own IP53 rating, making them a perfect pair for inclement weather.
In terms of optical performance, the Fusion One Next is nearly as sharp as the premium X4. While I noticed a very slight warming of the highlights in side-by-side tests, it was easily corrected in post-processing or by a simple white balance tweak. The aluminum frame is low-profile, ensuring it doesn’t cause dark corners when used on lenses like the 12-100mm f/4 IS PRO. It lacks the tactile “grip” of a brass frame, but the smooth rotation of the polarizing element is consistent and well-damped. If you need a reliable CPL that can take a beating in the field and still deliver sharp 50MP Handheld High Res shots, this is the best value choice on the market.
- Outstanding water and oil resistance for field use
- Excellent balance of price and optical resolution
- Very slim frame prevents vignetting on PRO lenses
- Aluminum frame is more prone to cross-threading if forced
- Slightly harder to turn with heavy gloves compared to brass

K&F Concept Nano-X Series UV Filter View on Amazon View on B&H
| Glass Type | Japanese AGC Glass |
|---|---|
| Thickness | 3.3mm Ultra-Slim |
| Coating | Green Multi-Coating (Anti-Reflective) |
| Hardness | Scratch Resistant |
| Transmission | 99.6% |
The debate over UV filters is endless, but when you’re shooting with a $1,300 M.Zuiko 12-40mm f/2.8 PRO II in blowing sand or salt spray, having a sacrificial layer of glass is just common sense. The K&F Concept Nano-X is my go-to recommendation for budget-conscious OM-1 users because it manages to provide high-quality Japanese AGC glass at a fraction of the cost of the big names. In my testing, I found no perceptible loss of sharpness when shooting at the standard 20MP resolution, and even in the 80MP Tripod High Res mode, the impact on fine detail was negligible.
The primary reason to choose the Nano-X over even cheaper “Amazon basics” options is the coating. It features a 28-layer nano-coating that does a surprisingly good job of suppressing flare when shooting toward the sun. I’ve used this filter specifically during bird-in-flight sessions where the OM-1 II’s subject detection was tracking through messy environments; the filter stayed clear and didn’t confuse the AF system. The ultra-slim 3.3mm frame is also critical for Micro Four Thirds users, as it prevents any mechanical vignetting on lenses like the 7-14mm (if using a third-party adapter). It’s not a “creative” filter, but as a “security guard” for your expensive glass, it’s unbeatable for the price.
- Highly affordable protection for expensive PRO-series lenses
- Slim enough to be left on the lens permanently
- Impressive flare resistance for a budget-tier filter
- Not as easy to clean as the Hoya or Breakthrough options
- Does not provide any polarizing or ND benefits

Tiffen Black Pro-Mist 1/4 Filter View on Amazon View on B&H
| Effect Strength | 1/4 (Medium-Soft) |
|---|---|
| Technology | ColorCore™ Process |
| Frame Material | Black Aluminum |
| Primary Use | Diffusion / Glow |
| Compatibility | Best on 25mm f/1.2 or 45mm f/1.2 PRO |
Modern digital sensors like the 20MP stacked CMOS in the OM-1 Mark II are incredibly sharp—sometimes too sharp for portraiture or “moody” street photography. The Tiffen Black Pro-Mist 1/4 is a niche but powerful tool that introduces a subtle glow around highlights and slightly lifts the shadows. In my portrait sessions, I found that this filter does a better job of smoothing skin tones than any in-camera “beauty” mode, as it works purely with the light entering the lens. It gives the M.Zuiko lenses a more “filmic” character that breaks away from the clinical digital look.
The 1/4 strength is the “Goldilocks” choice; the 1/8 is too subtle to notice, and the 1/2 can look like a hazy dream from the 1980s. When using this with the OM-1 II’s high-speed burst modes, I saw no impact on the autofocus speed or accuracy. It’s particularly effective when shooting in urban environments at night, turning harsh streetlights into soft, atmospheric blooms. You shouldn’t use this for landscape photography where you want maximum biting detail, but for storytelling and people, it’s a brilliant creative addition to your kit.
- Creates a beautiful, organic “bloom” around light sources
- Reduces the clinical over-sharpness of modern digital sensors
- Maintains critical detail while softening skin textures
- Reduces overall contrast, which may not suit all styles
- Can make images look “muddy” if there is too much flat, ambient light

Frequently Asked Questions
Do I still need a physical ND filter if I use the OM-1 Mark II’s Live ND feature?
For still photography, you rarely need a physical ND unless you’re shooting in extreme sunlight and need more than 7 stops of reduction (ND128). However, Live ND does not work for video. If you plan on filming, a physical Variable ND like the PolarPro is mandatory to keep your shutter speed at the correct double-frame-rate setting.
Will a 72mm filter cause vignetting on the 12-40mm f/2.8 PRO II?
No, the 12-40mm uses a 62mm thread. If you use a 72mm filter with a step-up ring, it will actually reduce the chance of vignetting because the filter glass is much larger than the lens opening. This is a common “pro hack” for Micro Four Thirds users to save money and improve performance.
What is the most common mistake when using a CPL on the 8-25mm f/4 PRO?
Using a thick, non-slim CPL at the 8mm wide end often results in dark “vignette” corners. Additionally, because 8mm is so wide (16mm equivalent), the polarizer can create an uneven “blue patch” in the sky. To avoid this, I recommend rotating the CPL slightly away from its maximum effect when shooting at the widest focal lengths.
Should I buy the Olympus/OM SYSTEM branded protective filters instead of third-party ones?
While the official OM SYSTEM filters are high quality (often manufactured by Kenko/Hoya), they are frequently more expensive than equivalent third-party options like the Hoya Fusion One. You aren’t losing any “brand synergy” by choosing Breakthrough or Hoya; the optical coatings on those premium third-party filters are often superior.
Can I stack a CPL on top of a UV filter for the OM-1 Mark II?
Technically yes, but I strongly advise against it on Micro Four Thirds lenses. Stacking two filters increases the distance from the front element, which almost guarantees vignetting at wide angles. It also introduces two more surfaces for internal reflections and ghosting, which can degrade the OM-1 II’s excellent contrast. Remove the UV filter before attaching a CPL.
Final Verdict
If you primarily shoot landscapes or water features, the Breakthrough X4 CPL is a mandatory investment that pays for itself in reduced post-processing time. For those on a budget who frequently shoot in wet or dusty conditions, the Hoya Fusion One Next offers the best durability-to-price ratio. If you are a video specialist, skip the polarizers and grab the PolarPro VND to unlock the OM-1 II’s true cinematic potential. As computational photography continues to advance, physical filters are becoming more specialized, but a high-quality circular polarizer remains the one tool your camera’s software simply cannot replace.
