SIRUI Venus Full-Frame Anamorphic Lens

Overview

The SIRUI Venus anamorphic lenses are a full-frame compatible set of cinema-primes with an anamorphic “squeeze”
factor (typically 1.6×, with optional 1.25× adapter for up to ~2×) and T2.9 maximum aperture. They are intended
to give a cinematic look — wide horizontal field of view, oval bokeh, characteristic lens flares (especially
blue streaks) and high resolution for full-frame mirrorless and cinema systems.

The lineup includes multiple focal lengths (35 mm, 50 mm, 75 mm, 100 mm, 135 mm, 150 mm) and multiple mounts
(Canon RF, L-Mount, Sony E, Nikon Z) making it versatile for various full-frame camera bodies.

Key Features & Benefits

• Anamorphic Squeeze (1.6× standard, optionally ~2× with adapter)
  Provides a wider field of view and a more cinematic aspect ratio (e.g., when using 16:9 sensor format you
  can get ~2.8:1 aspect after de-squeeze) — useful for high-end cinematic productions.

• Full-Frame Coverage
  Designed for full-frame sensors, giving more image area and flexibility (including for crop/punch-in)
  compared to APS-C anamorphic designs. :contentReference[oaicite:4]{index=4}
• Cinematic “look” – Oval Bokeh & Blue Lens Flares
  The lenses produce the classic oval out-of-focus highlights of anamorphic lenses and characteristic
  horizontal blue streak flares when pointed at bright light sources — adding that “cinema lens” aesthetic.

• Varied Focal Lengths and Matched Aesthetic
  The set covers a range of focal lengths (35/50/75/100/135/150) all designed to share common color tonality,
  gear positions, filter thread size and overall optical character, so switching between them stays visually
  consistent. :contentReference[oaicite:6]{index=6}
• Cine-style Build / Gear Rings / Support Friendly
  The barrels have standardized filter threads (e.g., 82 mm for many lengths), geared focus & aperture rings
  for follow focus rigs, ¼-20 support threads, etc., making them suitable for serious video / film work.

• Optional Adapter for Higher Squeeze Ratio
  A 1.25× adapter can be screwed on top of the 1.6× anamorphic to achieve ~2× squeeze, giving even wider
  aspect ratio and stronger anamorphic effect. :contentReference[oaicite:8]{index=8}

Summary of Benefits

• Provides a true cine-look in full-frame format with anamorphic characteristics (wider field, oval bokeh,
  lens flares) at a relatively accessible price compared to some high-end cinema anamorphics.
• Full-frame coverage gives more flexibility for high-resolution sensors, cropping/punching, and better use of
  sensor area.
• Set consistency means you can build up a kit of focal lengths and maintain matching visual character, easing
  multi-lens productions.
• Geared rings, support threads and cine-friendly build make it useful for serious video/film rigs.
• Optional adapter for higher squeeze gives you creative flexibility (even more dramatic widescreen or
  reframing in post).

Perfect For

• Cinematographers and filmmakers using full-frame mirrorless or cinema cameras who want to capture authentic
  anamorphic aesthetics without paying ultra-high prices.
• High-end video productions, commercial work, narrative filmmaking where lens character (bokeh, flares, wide
  field) matters.
• Pro content creators who want a matching set of primes to cover focal lengths while keeping visual
  consistency.
• Hybrid shooters with full-frame cameras who want to step up from spherical lenses into anamorphic territory
  and explore widescreen look.

In summary: the SIRUI Venus Full-Frame Anamorphic Lens series delivers cinematic imagery via
true anamorphic design, full-frame compatibility, and a range of focal lengths — a compelling option for
filmmakers looking for anamorphic aesthetics without the extreme cost of legacy high-end cinema lenses.
