“Sirui has created a truly accessible entry point into the world of anamorphic photography, delivering the look and feel of cinema films without being overly stylized or breaking the budget. The Saturn V2 lenses are easy to use and look fantastic!”

“I’ve always been fascinated by anamorphic lenses and have used several SIRUI lenses over the years. What I love about them is the organic effect they give the image - less clinical and sharp, with a beautiful character that feels more cinematic and vibrant. And the fact that I can now use true vertical anamorphics is the icing on the cake, offering me flexibility I haven’t found in any other lens.”

Jason Morris

“With vertical shooting using conventional anamorphic lenses, flares and bokeh are also oriented vertically. With the brand-new Saturn Version 2s' new design, however, the lens can be rotated so that flares and oval bokeh remain horizontal. This offers maximum flexibility - thanks to the square image capture, you can conveniently crop your image horizontally or vertically.”

Frequently Asked Questions

How do I switch between horizontal and vertical shooting?
>

Flip the switch, rotate the lens 90 degrees, and lock it into place. The Saturn V2 switches between horizontal and vertical shooting without changing lenses.
Which aspect ratios are possible in horizontal and vertical modes?
>

With its constant 1.6x squeeze ratio, the Saturn V2 delivers an aspect ratio of approximately 0.9:1 after desqueezing with a 9:16 image and 1.07:1 with a 2:3 image. In landscape orientation, the aspect ratio is 2.84:1 at 16:9 and 2.4:1 at 3:2.
What are the benefits of vertical anamorphic shooting with the Saturn V2?
>

With its constant 1.6x squeeze ratio, the Saturn V2 delivers a wider, more complete field of view for vertical content while preserving its distinctive anamorphic look. Compared with a standard lens, it creates greater spatial depth, oval bokeh, and natural horizontal light streaks for a more cinematic image.
Which focal length should I use?
>

Choose 35 mm for wide-angle shots and establishing shots, 50 mm for street scenes and documentaries, and 75 mm for portraits, character shots, and narrative close-ups.
