Very good (MFT version)

The Objektib is made with value and fits securely on the housing. The aperture can be adjusted neatly and also the focus ring has a good resistance. The toothed ring is as would be expected for the ideal follow-Focus application.

Free from the hand operated: wonderful control.

For me, however, was already clear beforehand: This is not a simple plan-objective, but to the rig. Weight and size are the one that relatively small and singular screw the camera body (GH2, but applies to all video-snapping) does not stand up against the rotating force of the FF. This rises and every (!) Lens reduces minimal. By contrast, only one lens support, which also relieves the lens mount helps.

The image quality is absolutely convincing. Photographic or blur I could find none.
