- Optical improvements include: an aspherical surface, glass with anomalous partial dispersion and a high refractive index, a floating element including a brand new, high-precision adjusting mechanism, lens coating, and sophisticated measures to reduce internal reflection
- Floating element maintains the outstanding imaging performance even at the minimum range of 2.3' (0.7 m)
- Built-in lens hood can be locked in its extended position to prevent it from accidentally being pushed back in
- Includes "6-bit code" which allows the digital M8 camera to identify which lens is being used, and also to store this information in image metadata
