RE: TC and Tubes for macro

[Alan Chan]

I have never done that but my brain tells me to put TC between extension 
tube and the lens. However, the Pentax TC manual mentions they were not 
designed for macro works.

Has anyone performed tests on TC/tube combos for macro use? If you were 
using
tubes and a TC would you put the TC or tubes directly behind the lens?
