Sirui 40mm T1.8 1.33X S35 AF Anamorphic Lens (L Mount Neutral Flare)

Sirui 40mm T1.8 1.33X S35 AF Anamorphic Lens (L Mount Neutral Flare) | Widescreen filmmaking with autofocus

The 1.33x anamorphic squeeze gives this Sirui a distinct widescreen purpose: it’s made for filmmakers who want a cinematic frame without giving up autofocus. It’s an interchangeable lens for video and filmmaking, with a 40mm focal length and a neutral-flare look. The design suits APS-C and Super 35 filmmaking, from composed dialogue scenes to moving shots where keeping focus manageable matters. Its Leica L mount makes it relevant to filmmakers building around that system. Rather than a general-purpose stills lens, this one makes most sense when you’re planning shots for a widescreen result and want anamorphic character as part of the image. You’ll need to account for the squeeze in your editing workflow, but that’s part of using anamorphic footage, not an extra effect the lens applies for you.

Making the widescreen look work

Think about the frame while you compose: give faces and important details room across the image, and leave space for movement when a subject crosses the shot. The neutral-flare version is a sensible direction when you want anamorphic character without making a colored flare the main visual event. It’s a focused filmmaking tool, so its appeal is strongest when you have a widescreen look in mind rather than needing one lens to cover every kind of shooting.
