"I try to start these articles by putting my preconceptions out there first. Every reviewer or blogger has them, they affect our opinions, and you have a right to know them. So I’m writing this introduction the day before our first copies arrive.
The lens is designed by IB/E Optics GmbH in Germany and manufactured by Kipon (aka Shanghai Transvision Photographic Equipment Co. Ltd). IB/E has developed a number of lenses and adapters for the Cinema world and other optics, so I figured the design would be good; probably a telecentric lens with a built-in speedbooster-type element or group. Kipon is known as a lens adapter company, although Shanghai Transvision has also manufactured and distributed video and photo accessories. They are rumored to manufacture lenses for other brand names, so they have some lens manufacturing experience. But, I have to say, my expectations for build quality weren’t great.
Okay, so much for what I expected. There are now five new copies sitting on my desk so let’s take a look."
