Talk:Sigma SA-mount

The compatibility paragraph is very garbled: "Despite of the physical similarities Pentax K-mount (PK) lenses can't really be fitted straight onto the SA-mount as well, once the protruding AA lever and AA protector outcrop are removed, though the fit is slightly loose as the SA-mount has a slightly bigger bore than the PK-mount." If you can make sense of this, or know what it is meant to say, then please rewrite this.
