Changing Lens Mounts

[seandudding]

So I currently have a lot of Sigma SA Mount lenses. When I bought my kit 3 years ago I was taken by the Sigma SD10's Foveon Sensor technology. I am now getting fed up with there slowness to keep up with Canon etc in the body upgrades.

I know the Sigma mount is very similar to the Canon mount, and I know people have been able to change mounts. Sigma use to offer this service but no longer do so.

Does anyone know someone who may be able to convert these lenses for me?

Thanks Sean
