Although the imaging circle actually covers 35mm, I believe the lens was designed for 16mm movie cameras. The reason I am saying that is because, like many of the c-mount cine lenses, this one is only sharp in the middle of the frame, but it does produce some interesting images, especially on full frame. I shot some pictures with my old 1Ds couple years ago with it, and I like some of its quirky qualities.
Even though my copy of this lens is in horrible condition, with coating on its rear elements disintegrated into a mess that I can't remove. If you look at it from a side, it looks like it has a layer of haze. Consequently, flare is a killer, and it does not have very high contrast when there is side light. But, it's very sharp in the middle. I think this lens will be pretty good at the edges on the micro 4/3 format, but I haven't tried it yet.

You can see from the above full frame picture that the edges isn't great, but with an APS-C size sensor, and stopped down to around f8, it's quite all right, as below.
