SIRUI Aurora 35mm F1.4 wide-angle autofocus lens
Product description
This wide-angle prime lens brings a natural perspective and fast low-light performance for full-frame L mount cameras, combining a bright aperture with autofocus for stills and video work. It suits street, travel and portrait photography where shallow depth of field and smooth bokeh are required while keeping handling straightforward.
Key Points
The lens delivers strong centre-to-edge sharpness, with aspherical, ED and HRI elements working together to reduce chromatic aberration and maintain authentic colours. Its fifteen-blade diaphragm helps create soft, rounded bokeh that can add a pleasing separation between subject and background. Autofocus is driven by a step motor that supports eye AF and object tracking, offering smooth and precise focusing for moving subjects and casual video use. The physical controls include an AF/MF switch, an AFL button and an aperture ring with switchable click stops, giving tactile control whether you prefer manual adjustments or quick AF intervention. Consider that, according to the manufacturer, performance remains high even at the maximum aperture, but users seeking extreme long-range reach will need a longer focal length.

Usage Recommendations
Use the wide aperture to separate subjects from busy backgrounds, especially in low light where the f/1.4 setting offers more flexibility. For street and travel work, keep AF engaged for quick captures and switch to manual for deliberate compositions or when shooting in consistent lighting. When recording video, rely on the step motor for smoother focus pulls, and consider engaging the aperture click stops when you want audible feedback from the ring during controlled adjustments. 📷
