@Brightcolors: I might be wrong, but I think the TC diminishes the DOF, so that f2.8 on a 100mm gives about the same DOF as f4 on the combination with the 1.4x TC...????


@popo: I have the Kenko 1.4x converter pro300 dgx, according to Kenko it fits on the Canon 100mm IS, I tried to find out if it also fits the Sigma 150mm OS, but I did not get any results.


I googled a bit more about IS and OS, I think both Sigma 150mm OS and Canon 100mm IS have tilt & shift corrections.


Thanks popo and Brightcolors!
