Sirui Astra Series Astra Series T1.8 1.33x 100mm Full-Frame Anamorphic 100mm
Combining a fast T1.8 aperture with selectable autofocus in a full-frame anamorphic, this 100mm lens delivers a 2.4:1 aspect ratio without cropping and neutral streak flares. Its 18-element optical design and expansive 44mm image circle ensure edge-to-edge sharpness, while the 13-blade diaphragm creates oval bokeh and vertical background stretch. This lens is best for cinematographers shooting narrative or music video content on Nikon Z who need classic anamorphic character with modern AF convenience.
