Best Lens Filter for Leica Q2
The Leica Q2 is a masterpiece of optical engineering, centered around that legendary 28mm f/1.7 Summilux lens. However, leaving such a premium element exposed to the elements is a risk most photographers aren’t willing to take. Whether you are battling street dust in NYC or sea spray on the coast, the right 49mm filter is essential. My top recommendation is the B+W Master Series, which offers the perfect balance of ruggedness and optical transparency to complement your 47.3MP sensor.

Best Lens Filter for Leica Q2: Detailed Reviews
B+W 49mm Master 010 UV-Haze MRC Nano View on Amazon View on B&H
When you’ve spent thousands on a Leica Q2, putting a cheap piece of glass in front of that Summilux lens is almost sacrilegious. The B+W Master Series (which replaces the legendary XS-Pro line) is the gold standard. I’ve used these filters for years, and the MRC Nano coating is a lifesaver; fingerprints and water droplets wipe off with a single pass of a microfiber cloth. The brass mount is another highlight—it’s much less likely to bind or “freeze” onto your lens threads compared to aluminum alternatives. Optically, it is virtually invisible, maintaining the biting sharpness of the Q2’s 47MP sensor. While it’s pricier than entry-level filters, the peace of mind and the lack of ghosting in backlit situations make it the only logical choice for a high-end fixed-lens camera. The slim profile also ensures you won’t see any additional vignetting on that wide 28mm frame.

Hoya 49mm NXT Plus UV Filter View on Amazon View on B&H
The Hoya NXT Plus is the sweet spot for many Q2 shooters. It provides a significant step up from budget glass without hitting the triple-digit price tags of premium German brands. I find this filter particularly impressive because it features a waterproof top coat that actually works, making it great for rainy days or humid environments. The 10 layers of multi-coating do a fantastic job of suppressing flare, which is vital since the Q2’s 28mm lens can be prone to catching stray light if you aren’t using the lens hood. It uses a low-profile aluminum frame that is surprisingly sturdy and threads smoothly. While it doesn’t feel quite as substantial as the brass B+W, the optical performance is very close. If you want to protect your lens but would rather save your cash for a leather half-case or extra batteries, the Hoya NXT Plus is the smartest buy on the market.

Tiffen 49mm UV Protector View on Amazon View on B&H
If you’ve just liquidated your savings to buy a Leica Q2 and literally have twenty dollars left, the Tiffen UV Protector is your “better than nothing” solution. It is a simple, no-frills piece of glass designed primarily for impact and scratch protection. Unlike the higher-end options, Tiffen filters are often non-coated or have minimal coating, which means you might notice a slight increase in lens flare or ghosting when shooting directly into the sun or bright street lights at night. However, for everyday physical defense against sticky fingers or dust, it does the job. It’s made in the USA and uses Tiffen’s ColorCore process. I wouldn’t recommend this for professional gallery work where maximum contrast is required, but as a temporary placeholder to keep your Summilux safe until you can upgrade, it’s a functional and widely available choice that fits the Q2’s 49mm thread perfectly.

Leica 49mm UVa II Filter, Black View on Amazon View on B&H
For some, only Leica glass should sit in front of a Leica lens. The UVa II filter is specifically designed by Leica to match the optical properties and physical aesthetics of the Q2. The black finish on the ring is an exact match for the Q2’s lens barrel, ensuring that the camera maintains its sleek, stealthy look. Beyond looks, the glass is of exceptional quality, designed to handle the high resolution of the Q2 sensor without adding any chromatic aberration. You’ll notice that the threading is incredibly precise, and the filter allows you to still use the original Q2 lens hood without any clearance issues. It is the most expensive option on this list, and while you are certainly paying for the brand name, you are also getting a product that Leica guarantees will not degrade the performance of their world-class Summilux optics. For many owners, that guarantee is worth every penny.

B+W 49mm Master High Transmission CPL View on Amazon View on B&H
While most people look for a UV filter for protection, a Circular Polarizer (CPL) is the one filter whose effect cannot be replicated in Lightroom. If you use your Q2 for landscape or architectural shots, this B+W Master CPL is a game-changer. The Kaesemann HTC foil provides incredible contrast and color saturation while only losing about 1 to 1.5 stops of light—much better than older CPLs that eat 2-3 stops. It effectively removes reflections from water, glass, and foliage, making the colors “pop” in a way that looks natural and professional. I find it particularly useful for street photography when you want to see through car windows or shop fronts. The build quality is top-tier Master series brass, and the rotation is smooth and damped, giving you tactile control over the polarization angle. It’s a specialized tool, but for the 28mm wide angle of the Q2, it’s an essential addition to your bag.

Frequently Asked Questions
Does the Leica Q2 need a 49mm filter?
Yes, the Leica Q2 and the Q2 Monochrom both feature a 49mm filter thread on the front of the Summilux 28mm f/1.7 lens. Using any other size would require a step-up or step-down ring, which can interfere with the lens hood or cause significant vignetting. Stick to 49mm for a native, flush fit that allows the use of the original Leica accessories.
Will a filter cause vignetting on the 28mm lens?
Because 28mm is a wide-angle focal length, thick filter frames can potentially clip the corners of your image. This is why I strongly recommend “Slim” or “Low Profile” filters. Most modern high-end filters from B+W, Hoya, and Leica are designed with slim frames specifically to prevent this issue on wide-angle lenses, ensuring your 47MP files remain clear from edge to edge.
Can I still use the Leica lens hood with a filter attached?
Yes, you can! The 49mm filter threads onto the inner part of the lens, while the Leica Q2 lens hood screws onto the outer threading of the lens barrel. As long as you choose a standard or slim 49mm filter, the hood will fit perfectly over it. In fact, many photographers leave a UV filter and the hood on at all times for maximum protection.
Do filters degrade the image quality of the Q2?
Technically, adding any layer of glass can introduce reflections. However, with high-quality multi-coated filters like the B+W Master or Leica UVa II, the degradation is virtually immeasurable. In contrast, cheap, non-coated filters can cause significant flare and loss of contrast. On a camera as capable as the Q2, the “protection vs. quality” trade-off is only worth it if you use premium glass.
Is the Leica brand filter better than B+W?
Optically, they are very similar. Both use top-tier Schott glass and advanced coatings. The Leica brand filter offers a perfect aesthetic match in terms of color and finish to the Q2 body. The B+W Master series offers a brass mount which is arguably more durable for frequent changes. Most users choose based on whether they prefer the “Leica” name or the specialized engineering of B+W.
Final Verdict
If you want the absolute best for your Leica Q2, the B+W Master Series is the clear winner for its durability and optical perfection. Purists who want an exact aesthetic match should look no further than the Leica UVa II. However, if you are looking for a reliable “set it and forget it” protector that won’t empty your wallet further, the Hoya NXT Plus is a phenomenal value that doesn’t compromise on the Q2’s legendary sharpness.
