B&W International Adapter ring Step-Up 67-77 mm

B+W adapter rings for adapting filters, supplementary lenses, and other attachments to lenses with different filter thread sizes.

Features:

• Step-Up adapter ring
• Lens thread: 67 mm
• Filter thread: 77 mm
• High-quality and precise craftsmanship
• Made of metal

Typically, larger diameter filters or attachments are adapted to smaller lens diameters. For example, in a photography setup that includes lenses with 52 mm and 49 mm filter threads, these rings allow the use of 52 mm filters on both lens groups. This not only saves money but also reduces volume and weight in the camera bag.
