The short focal length of the telephoto lens is combined with a bright maximum aperture of f/1.4, offering control over depth of field and benefits in challenging lighting conditions.
The optical design includes:
- Extra-low dispersion elements
- High refractive index
- Reduction of aberrations and distortions
- High sharpness and color accuracy
The lens features an STM stepping motor for fast, nearly silent, and accurate autofocus performance, as well as full-time manual focus override. The internal design contributes to fast performance, while the built-in micro-USB port allows for future firmware updates. The black finish matches similar cameras.
