Sirui Astra Series AST-100-LN 100mm
Combining a fast T1.8 aperture with selectable autofocus in a full-frame anamorphic lens, the 100mm focal length delivers a 2.4:1 widescreen image with characteristic blue streak flares and no cropping. The 13-blade diaphragm creates oval bokeh and the weather-sealed, 700g build maintains a practical 67mm filter thread for on-set versatility. This lens is best for narrative filmmakers and solo operators who need the classic anamorphic look with the speed and convenience of reliable autofocus on Sony E-mount cameras.
