Obito was so fast with Kamui that during the Five Kage Summit, he entered the Dust Release cube Sasuke was in and warped him and Sasuke away before it exploded. That's easily one fo his best speed feats, especially considering the cube was already glowing and the next instance after that was obliteration.

Also, concerning the whole Amaterasu argument. If Obito can warp away objects he comes into contact with, what makes people think he can't warp away flames in contact with his body? He also has the Regeneration Ability, so that would explain why there was no burns left on him.
