The FreePower RA58EOS ring is a helpful tool for working with reverse mount lenses. The adapter allows you to attach a 58 mm filter to the Canon EF / EF-S bayonet.

When shooting with the reverse adapter, there is always a risk of mechanical damage to the rear lens element or dust being sucked inside it. For such an eventuality, the FreePower RA58EOS adapter was designed, which, when connected to the lens, enables the use of a protective filter.

The adapter is equipped with an optics mount in the Canon EF and Canon EF-S standard. The bayonet has a locking lever that allows for quick assembly and disassembly. On its other side there is a 58 mm thread. Everything is made of metal.
