I already have three lenses to try with it: 28-300 asph IF, 70-300 non Apo and 70-300 Apo DG.
The 28-300 is probably too old and does not focus. Both 70-300s work all right but step into focus slowly in poor light or at f/5.6 max aperture. Neither will focus in AF-C, which I knew in advance.
Both the 70-300s appear to slightly back focus, so adjustments might be tried. Since I'm using DFD contrast AF, that seems odd. We'll try more stuff soon.
