sounds like a lot of light loss. but i don't plan on doing any macro - just closer portraits.
your ETs don't have lenses in them do they? I haven't experienced a loss of light.

and yes, with my longer lensees, if I use the small extension tubes, I can bring the subject slightly closer without turning the shots into macros.
