Christine,were you using the Kenko ext tubes?.I have a set of these,bought at the end of the year,and only tried once.I tried with the 400F5.6 and then with the 100-400,but only obtained a pic with the latter.But I was much closer than 6ft,more like 2ft.Did you use any specail settings,and did you use all the tubes.I would love to try this method for butterflies etc,in the summer,as I am unable to crouch down close to the subject,but would find it much easier to be able to shoot from my normal distance.
I did take a couple of shots in low light using the 1x4 on auto focus today,and not bad.When I have re -sized,(it takes ages) will post one.
