That might be the case with the new HC120 macro but my HTS plus 80 or plus 100 definitely performs better at that distance than my HC120. I quite often grab the HTS/80/13mm extender (or the same combo but with the HC100 instead of the 80) instead of the HC120.
Now, I am told by several people that have the HC120mkII and have used the HC120 as well that the new version is much better at close range. I have just yet not had the urge to pony up the money to replace my HC120. Maybe next year...
