The Voigtlander branded lenses available in LTM and "M" mount are much better than the fixed lens on the Olympus XA cameras, even though the lens on the XA is quite good for the camera size. On the XA, when I scan my slides at high resolution (4000 ppi) I notice chromatic abberations at the corners of the frame (color fringing). You won't see this with any of the Voigtlander lenses.
