Just had a look through several lenses with the A-200 attached:
100mm f2.8 slight vignetting
135mm f3.5 negligible vignetting
50mm f1.4 severe vignetting
50mm f3.5 bad vignetting
75mm-150mm bad vignetting (slightly worse at the 75mm end)
The vignetting looks worse as you stop down as it has a sharper "edge".
