Sigma Lens Resolution in MP?
2

In this recent thread , there were many posts, including the OP, that stated lens resolution as MP. Meanwhile, lens manufacturers continue to state lens resolution by MTF curves.

So, how does one measure lens resolution in MP? Any credible links to where that Unit of Measure is used?
