I don't need images, because I have that lens. :) It takes great pictures, even if it does focus slow and feels more like a toy than my kids Fisher Price camera!

In any case, the MTF at the Nyquist frequency is only important if your output can show it, but I think many Scarlet users will have 1080p as the max output, and the MTF there will be much better looking.

The macro lenses such as 100mm f/2.8 would be excellent telephoto lenses lenses on Scarlet 2/3", except that their focus mechanics for normal-distance subjects leaves something to be desired. I think there are some other good options.
