Hello folks. Not a whole lot of information on the Meopta 80 MD. I found only a handful of reviews and opinions but hardly any qualitative comparisons. Can any of you good folks comment on how the Meopta 80 MD would compare to the Meopta S2 or Kowa TSN-883 based on practical experience? What I'm looking for is how well the optics resolve at both ends of the zoom range, chromatic aberrations and smoothness/preciseness of the focuser, i.e. stiff rotation, backlash, etc. Any feedback would be much appreciated. -Norm
