I experimented with using the EF600/4L IS with the new EF2 II and EF1.4 tc's on the
moon out of curiosity. Conditions were ideal with no wind to speak of.
I was not pleased with the results . . . all images were too soft.
So, I am surprised that you had such success. Arthur Morris also states he uses ganged
converters on the faster IS lenses so you are in good company.
I will have to try again.
