77mm EF Mount Macro Reverse Kit

Engineered specifically for Canon EF-mount DSLRs, this macro reverse kit comprises a single 77mm aluminium adapter ring and a complementary rear lens mount protector — both machined from the same high-grade aluminium alloy and weighing a combined 64g. The adapter ring features a 77mm male thread on the lens-facing side and a fully profiled EF bayonet mount on the camera-facing side. The protector ring screws onto the reversed lens’s rear using the same 77mm thread standard, forming a rigid barrier around the mount. Suitable only for EF lenses with 77mm front filter threads, it supports manual focusing and stop-down metering while retaining native lens resolution and bokeh characteristics at extreme close focus distances.
