don't know about the MC version - I have an older 4x,32 Diatal C (W Germany) .. seems to track more consistently than the 1.75-6 and 2.5 Leupolds do fwiw
The Zeiss would be similar in quality to the FXIII, 6X36. The FXII is a good but lower performance scope at a couple hundred $ less. The FXIII is built to the same standard as the VXIII's. Phil.
