The VX-6 would be a better comparison, and the Z3 edges this one out as well in the lowest light (they are VERY close in good daylight). The VX-3i is a bit below those 2 in terms of resolving power, perceived brightness and edge-to-edge sharpness.
Bobby,
Have you looked at the VX-5HD? If so how did it stack up?
Sorry to the OP for the tangent.
