Georg, I am no "expert" on the TC16A, just intrigued as this little and overlooked piece of glass performs so well; though at FX bodies borders can suffer, at DX no problem and the center is very good.
Scott, I think both 55/2.8 and 105/2.8 are good at macro and at infinity.
My feelings/experiences (at least with my copies: two 55/2.8, one 55/3.5 and 2 105/2.8) revealed that in general the 55s are a little bit sharper and have almost no CA when compared to the 105/2.8. But the 105 micro is no slouch, far from that, and I was surprised with test results against the legendary 105/2.5:
