"This is Part II of my three part series on Zeiss/Contax lenses for video.
In my Part I article, I discussed cost and feasability considerations in regards to these lenses, and offered a few tips on how to shop for a set of your own Zeiss Contax lenses.

Some observations on resolution performance:"
