The B+W +5 close-up lens 55 mm offers an affordable entry into macro photography, allowing photographers to experiment with close-ups and miniature photography without significant financial investment. This lens attaches directly to compatible 55 mm lens threads and provides a +5 diopter magnification, enabling shorter focusing distances for detailed close-up shots. Constructed with the B+W F-Pro filter system, the close-up lens features a brass housing with a matte black finish to minimize reflections and prevent light interference. The F-Pro design includes threads on both sides, allowing for the use of standard lens caps and potential filter stacking, although multiple filter combinations on wide-angle lenses under 24 mm on full-frame cameras may cause vignetting. Made from high-quality optical glass manufactured in Germany, this close-up lens preserves image quality by correcting optical properties before the light reaches the camera sensor. The +5 magnification strength represents a moderate close-up capability within the available B+W range of +1 to +10 diopter options, with higher-numbered filters providing stronger magnification and shorter minimum focusing distances. This lens does not require exposure compensation or extended shutter speeds, although users should be aware of the significantly reduced depth of field characteristic of close-up photography. The precise brass construction ensures durability and reliable mounting, while the anti-reflective coating and matte surface contribute to maintaining optimal image contrast and color accuracy.
