SIRUI Astra 50mm T1.8 1.33x Full Frame E Mount NF

SIRUI Astra Series - 1.33x Full Frame Auto Focus Anamorphic Cine Lenses (50/75/100mm T1.8)

Cinema starts here - stories in true anamorphic look
With the Astra Series, SIRUI sets new standards: the manufacturer's first full frame anamorphic lenses with autofocus combine cinematic aesthetics, modern technology and maximum efficiency.
Available in 50mm, 75mm and 100mm T1.8, this series covers everything from expansive scenes to intense close-ups

. True cinemascope look - without compromise
Thanks to the constant 1.33x squeeze factor, the native 16:9 sensor format is transformed directly into the classic 2.4:1 widescreen format - without any cropping or loss of quality.

The result:

• Authentic cinematic proportions
• Oval bokeh highlights
• Characteristic vertical background stretching
• Immersive image effect with maximum resolution

The generous 44mm image circle fully covers full-frame sensors and makes the lenses ideal for modern mirrorless camera systems.

• No focus puller required
• Ideal for solo filmmakers & small crews

Additionally provide:

  for reliable, professional focus tracking.
