Lens optical design and image quality
The Sirui Aurora 85mm f/1.4 lens uses an optical system composed of 14 elements in 9 groups. The combination of aspherical elements and special types of ED and HRI glass effectively reduces chromatic aberration, spherical distortion and loss of contrast in backlight. The result is high sharpness from the centre to the edges of the image and consistent image performance across the aperture range.

Lens aperture and blur work
A maximum aperture of f/1.4 allows low-light shooting without the need to significantly increase ISO sensitivity, while also providing significant control over depth of field. The 15-blade aperture produces a smooth and natural background blur that is especially suitable for portraits, close-ups and creative video.

Auto focus and lens control
Autofocusing is achieved by a stepper motor that works quickly, precisely and quietly. The lens is also suitable for shooting video and supports advanced camera functions such as subject tracking and eye detection. The lens body features an AF/MF switch, a programmable function button and an aperture lock that allows you to select step or continuous aperture operation depending on the application.

Lens design and use in practice
The all-metal lens body is designed with durability and longevity in mind. The design is protected against dust and splash water, allowing use in harsh environments. The front optical element is coated with a protective fluorine coating to repel grease and dirt and facilitate maintenance during daily use.
