Sirui 1.25x Anamorphic Adapter for camcorder accessory

SKU CH-021X-MSF80

Transforms spherical lenses into anamorphic optics with a 1.25x squeeze for cinematic widescreen footage

  • Transform spherical lenses into anamorphic with 1.25x squeeze
  • Pair with 1.6x lens for 2x squeeze and thinner bokeh
  • Desqueeze 4:3 sensor footage to near 16:9 for broadcast
  • Shoot spherical 16:9 to achieve cinematic 20:9 aspect ratio
  • Bright T2.9 aperture maintains exposure in low-light conditions

Sirui 1.25x Anamorphic Adapter

The Sirui 1.25x Anamorphic Adapter attaches to a spherical lens to add a 25 percent wider horizontal field of view. It delivers the classic cinematic look associated with anamorphic optics, including distinctive stretched backgrounds. The adapter maintains a T2.9 maximum aperture for strong light transmission in varied shooting conditions. Its durable construction is built for professional filmmaking workflows.

Upgrade from spherical lenses

This adapter replaces the need for a dedicated anamorphic lens by converting existing spherical glass. It provides a 1.25x squeeze factor that yields a 20:9 aspect ratio when shooting in 16:9. Pairing it with a 1.6x anamorphic lens creates a 2x squeeze for more pronounced oval bokeh and shallower depth of field. The jump is worth it when you want anamorphic characteristics without replacing your lens kit.

Filmmakers seeking widescreen cinematic look

Videographers using spherical lenses who want a 20:9 aspect ratio will benefit from this adapter. It also suits owners of 1.6x anamorphic lenses aiming for a 2x squeeze and users of 4:3 sensor cameras needing a 16:9 output. Shooters requiring a different squeeze factor or those without compatible front filter threads should look at other solutions.

Questions about this item

What thread size or mount does the Sirui 1.25x Anamorphic Adapter need on the taking lens?

The adapter is designed to fit standard filter threads on spherical or anamorphic lenses, letting you stack it in front of the glass without a dedicated mount.

How do I attach the 1.25x adapter to my lens and what step is often missed?

Screw the adapter onto the lens filter threads, then rotate the front element until the blue alignment mark sits at the top so the squeeze axis stays horizontal.

Will the anti-reflection coating on the adapter need re-coating or replacement over time?

The multi-layer coating is bonded to the optical glass and does not degrade under normal use; no re-coating or element replacement is required.
