The Haida Rear Lens Filter Adapter Ring allows photographers to attach compatible Haida rear‑mount filters to the Tamron SP 15‑30mm f/2.8 Di VC USD and G2 lenses (Canon EF mount), which do not have traditional front filter threads. This enables creative exposure control, long‑exposure effects, and neutral density use behind the lens element without affecting optical performance.

Precision‑engineered from durable aluminum, the adapter ring provides a secure fit and effortless filter installation when needed. It includes a mini Phillips‑head screwdriver for installation and can remain on the lens indefinitely, making it a practical accessory for landscape photography, outdoor videography, and advanced lighting control workflows.
