The M mount version of the Lanthar is different to the SLR version ...

I doubt the optical design differs between the two. Rangefinder 90mm lenses have a lot of clearance between the last piece of glass and the sensor/film. You can easily fit a mirror in there.
On the other hand, I don't see any disagreement between the two tests. The numbers are actually very close. It might be that the 10MP of the Nikon D200 coincides with the MTF50 of that lens, and the higher resolution of the NEX outresolves that lens.
