I buy a "Tarcus TV-Lens 8mm F1.3" and a c-mount adapter for m4/3 (Olympus E-PL1)

1. The adapter is not the right. Is this a cs-mount objektive?

2. I put the objektiv with my fingers (without Adapter) on the camera and make 2 test shots. The focus was "inf". Why the macro shot is in focus but not the teleshot?

Is cs-mount on mft not compatible on mft?

thx a lot
