- 14-blade diaphragm (vs 9)
- 300 degree plus focus rotation
- Common outer dimensions (for the majority of the lenses) makes it quick and easy to interchange a lense during shooting
- Calibrated Lens Scales
- Interchangeable mounts
Switching mounts requires a torque wrench and a test chart or calibration device to set the back-focus for the lens correctly. The first time a new mount is put on a lens, it needs to be adjusted using shims (provided.) As long as you mark the shims and keep them with the mount, the swap after that is just a mechanical change; you don't need to recalibrate each time you switch mounts.
Currently they offer PL, Canon EF, Nikon F and Micro 4/3rds mounts. They had intended to offer Sony A mount (Alpha) but he said that they just don't see that as being a factor for video applications. He did say though, that they will "possibly" offer some more mounts later in 2011.
[Wild Speculation: with Sony's NEX-VG10, and the upcoming NXCAM 35mm camera sharing the Sony E-mount, perhaps Zeiss might be considering supporting that mount in place of the A mount?]
