You may want to check out Matt Grangers newest video(ironically its about audio and not visuals) . The reason why is that in the background he appears to have a 3rd lens that has the same visual characteristics as both the Zeiss Otus 85 1.4 and the 55 1.4 (http://youtu.be/guMdDse7t24?t=2m35s
)
Maybe a 35 1.4 to round out the range ?
