Fit larger filters without swapping lenses - with 77mm to 82mm step up threading
Threaded adapter screws onto any lens with a 77mm filter diameter and presents an 82mm thread so larger filters and hoods can be attached. Low-profile construction keeps the optical stack compact and reduces the chance of vignetting with moderate filter stacks.
Use one set of 82mm filters across lenses that have 77mm threads, cutting kit duplication and saving time during shoots.
Field-ready durability - thanks to aircraft-grade aluminium construction
Manufactured from aircraft-grade aluminium alloy, the ring is corrosion resistant and engineered to resist impact, torsion and compression. The surface is oxidised and sandblasted to create a hard finish and to help limit stray light entering the lens mount.
Durable, precision-machined rings withstand regular outdoor use while maintaining a professional, thin finish that users report as secure and accurate.
Keep accessories safe and tidy - with included case and microfibre cloth
Package contains two metal adapter rings, one microfibre cleaning cloth and one protective filter case, and includes a 24 month manufacturer's warranty. Protective kit reduces the chance of scratches and contamination while transporting accessories.
