B and W Filter 46MM CLOSE-UP +4 SC (NL4)

The B + W 46mm Close-Up +4 SC (NL4) is a screw-in close-up lens filter designed to shorten the minimum focusing distance of compatible lenses, allowing you to capture small subjects larger in the frame. It offers a practical and affordable way to explore close-up photography without moving to a dedicated macro lens system. For photographers working with compact primes, standard zooms, or travel lenses that accept 46mm filters, this accessory can open up creative opportunities for detail shots, texture studies, flowers, collectibles, crafts, and tabletop subjects.

Compatible With

• Lenses with a 46mm front filter thread

What a +4 Close-Up Filter Does

A close-up filter acts like a magnifying optic placed in front of your lens. The +4 diopter strength provides a stronger close-focusing effect than mild close-up filters, making it useful when you want to fill the frame with smaller subjects while keeping your kit compact and easy to use. It is especially appealing for photographers who want macro-like results from an existing lens setup without the added size, weight, or cost of a separate macro lens.

Optical Performance

This B + W close-up filter uses optical glass construction and a single coating design, identified by the SC designation. The coating helps reduce internal reflections compared to completely uncoated glass, which can improve contrast and help control flare in many shooting conditions. As with most close-up accessories, best results are typically achieved with careful lighting, moderate apertures, and attention to focusing distance.

Why Choose a Close-Up Filter

Close-up filters are popular because they are simple to use and preserve full light transmission better than extension-based solutions that may affect exposure or handling. They also maintain autofocus compatibility on many lens and camera combinations, though manual focus is often preferred for precision at close distances. For hobbyists, travelers, and content creators, a compact close-up filter can be a very convenient addition to the camera bag.

Best Uses

The 46mm Close-Up +4 SC (NL4) is well suited for photographing flowers, jewelry, coins, stamps, food details, craft work, textures, and other small subjects. It can also be useful for product photography when you need a tighter framing than your lens normally allows. Because it threads onto the front of the lens, setup is fast and straightforward, making it a practical tool for spontaneous close-up work.

Handling and Shooting Tips

For the sharpest results, use steady support such as a tripod when possible, stop down moderately to increase depth of field, and use bright, even light to keep shutter speeds comfortable. Since depth of field becomes very shallow at close distances, careful focus placement is important. If your lens extends while focusing or zooming, always verify working distance and framing before critical shooting.

Build and Mounting

This filter features a 46mm threaded mount, allowing it to attach securely to lenses with matching front threads. Its slim, lightweight format makes it easy to store in a pouch or accessory case, and it can be a smart option for photographers who want an occasional macro-capable tool without carrying additional lenses.

B + W Heritage

B + W is widely recognized for precision photographic filters and optical accessories, with a long-standing reputation for quality manufacturing and dependable performance. The company has been a trusted name among photographers who value durable construction and optical consistency across filter categories ranging from protective and polarizing filters to specialized creative and close-up designs.

Recommended Accessories

To get the most from this close-up filter, consider pairing it with a lens cleaning cloth, blower, protective filter case, compact tripod, LED light for close work, and a step-up or step-down ring only when used appropriately with compatible optics. Good lighting and stable support can make a noticeable difference in close-up image quality.
