It seems that the digital t/c is known to do a pretty good job. It sounds like this only changes the JPG (basically zooms the jpg). Do you agree with this? Reason I am asking is I set the camera to only shoot raw, so I only have half as many files to manage, I only edit raw anyway, and export to jpg for the web I guess. Only fooling around right now regardless. So the question is I guess is the t/c useless for raw only shooters? I think it is.
