- Excellent performance at work from 30mm, with a 4.0 aperture that is incredibly crisp, even too much so. It's possible that you struck it rich with the carcass.
- The price is around average. On the other hand, I only need to start at 30 millimeters before I can use it without mounting it. Very black when viewed from a wide angle (24mm). On the other hand, everything is incredibly simple and quick.
