the A22 will be just fine i suppose,
a great lens for small and medium 8>1m) sized painting is obviously a 120mm Macro, fine, sharp. I have a V-system, whenever the 120mm is too long, i take the 80mm and the 60mm. if i'm on location and there's no place to move. I'm not that happy with the barrel distortion of the 60mm at 4-6m from a rectangular frame, I wonder how it will be with a wider lens.
