I was on the canon learning site and one of the pro photographers was shooting using a 70/200L and he said when he wants to get macro shots he just puts an extender on (no glass in it, looks about 3 or 4 inches long). He took some macro of some fosil in a rock and it looked really good. He said he does this so he don't have to carry a lot of equipment. Question is why does that work??????? Pat

Could you use an extender with the 70-200mmto take photos indoors? say, to sub for a 28-50mm? It would be awfully long though.

Using an extension tube doesn't just bring in the mfd, it severely limits the range of focus. Like maybe an inch from minimum focus to maximum focus. It's pretty much only for macro use.
