The Atlas EF Mount Kit is designed to convert the Orion Series lenses to be used natively on EF mount cameras.
- All shims are stainless steel and are stamped with their thickness value for easy recognition.
- Mounts can be easily changed with the recommended number of shims (marked on the inside of each mount) and a T6 Torx driver in a clean environment. Please take care to use the mount shim thickness indicated.
- For instructions on how to swap out mounts, please see the Orion Series Owner’s Manual (page 7).
