This hard-wearing aluminium mount adapter ring allows you to use all M42 mount lenses on your Sigma SD cameras or SA mounts, saving you the expense of a costly and irreversible conversion.

Don't worry, infinity focus is still achievable and to make life that little bit easier, the ring also comes with a key which slots into the adapter for easy, twist and turn attachment and removal.
