B and W Filter 40.5MM CLR UV HAZE MRC (010M)

The B+W Filter 40.5mm Clear UV Haze MRC (010M) is a premium protective filter designed for lenses with a 40.5mm filter thread. Based on B+W's well-known 010 UV Haze design, this filter absorbs ultraviolet light while serving as a highly practical clear front-line shield for your lens. On most modern digital cameras, the visible imaging effect of a UV filter is subtle, but the protection benefits are significant for everyday use.

Compatible With

• Lenses with a 40.5mm front filter thread

Premium Optical Protection

This filter is made for photographers who want to protect the front element of their lens without compromising image quality. It helps guard against dust, dirt, fingerprints, sea spray, light moisture, and accidental contact during transport or shooting. Because it uses quality optical glass, it is intended to preserve sharpness and contrast while acting as a sacrificial barrier that is easier and less costly to replace than a damaged lens front element.

B+W MRC Coating Advantage

One of the key features of this model is B+W's Multi-Resistant Coating (MRC). This advanced coating reduces internal reflections that can otherwise contribute to flare and ghosting, especially when photographing backlit scenes or bright point light sources. The coating also improves the filter's resistance to dirt and water, making the surface easier to clean compared to uncoated filters.

UV Haze Function

The 010 UV Haze filter is designed to cut ultraviolet light, which historically helped reduce bluish cast and atmospheric haze in film photography, especially in open shade, mountain, coastal, and distant landscape scenes. In digital photography, UV sensitivity is generally already controlled by the camera sensor stack, so many users select this filter primarily for physical lens protection and the convenience of leaving a high-quality clear filter mounted full time.

Why Choose a B+W Filter

B+W filters have long been respected by photographers for their precision manufacturing, dependable optical quality, and durable construction. Compared with basic protective filters, the B+W 010M stands out through its better coatings, stronger build quality, and trusted performance. For photographers using compact system lenses, premium compact primes, or specialized optics with a 40.5mm thread, choosing a high-grade filter helps ensure the lens performs as intended.

Ideal Uses

This 40.5mm UV filter is well suited for travel photography, day-to-day shooting, street photography, hiking, family documentation, and general outdoor work. It is especially helpful in environments where blowing dust, fingerprints, drizzle, or salt spray can reach the front of the lens. Instead of cleaning the lens element repeatedly, photographers can clean the filter surface and preserve the condition of the lens beneath it.

Handling and Care Tips

To get the best performance, confirm your lens has a 40.5mm filter thread before mounting. Clean the filter with a blower first to remove loose grit, then use a clean microfiber cloth or lens tissue for smudges. Keeping the filter clean helps maintain contrast and minimizes the chance of flare in challenging light. Pairing the filter with the correct lens hood can provide added protection and further improve resistance to stray light.

Recommended Accessories

Useful companions for this filter include a microfiber cleaning cloth, lens cleaning solution, blower, lens cap sized for your lens, and a dedicated lens hood. A protective pouch or small filter case can also be helpful when storing spare filters in a camera bag.

In Summary

The B+W 40.5mm Clear UV Haze MRC (010M) is an excellent choice for photographers seeking dependable front-element protection with high optical standards. Its MRC coating, quality glass, and practical UV/protective design make it a strong everyday accessory for any lens that accepts 40.5mm filters.
