Really, the *main* stupid thing Sigma did was the development of the
'Sigma' mount. They should simply have picked one of Nikon / Canon /
Pentax.

Not so easy. These manufacturers are under no obligation to share the
technical details of their lens mounts with Sigma.

Sigma already makes lens for those mounts.


Look at all the problems Sigma lenses have with compatibility with other
manufacturer's cameras. Can you imagine if Sigma bodies had to be compatible
with Canon or Nikon or Pentax lenses? Well. we'll soon see if the Sigma
manufactured, Kodak DCS14/c works with all the Canon lenses.


yes but how much of that is real insurmountable incompat vs tradeoffs in making
all the same lens for 5 different mounts?
