- Four aspherical elements are featured in the optical design to control spherical aberrations in order to produce a high degree of sharpness while also limiting distortion.
- One Super ED and three ED elements are used to suppress chromatic aberrations and color fringing for improved clarity and color accuracy.
- Nano AR Coating has been applied to reduce surface reflections, flare, and ghosting for increased contrast and color rendering in strong lighting conditions.
- Constant f/4 maximum aperture offers consistent performance throughout the zoom range.
- Direct Drive Super Sonic wave Motor AF system and internal focus mechanism provides quick, quiet, and precise autofocus performance that is suitable for both stills and video use.
- Customizable focus hold button on the lens barrel for intuitive tactile control and rapid access to select settings.
- Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.
- Integrated lens hood helps reduce flaring and also provides some physical protection to the front lens element.
