Lens Overview — Sirui 1.33x Anamorphic Lens Collection for MFT

The Sirui Mars Anamorphic Lens Collection for Micro Four Thirds brings together four prime lenses spanning 24mm, 35mm, 50mm, and 75mm focal lengths, all designed for the MFT camera system. Each lens in the collection is of the anamorphic type, delivering the distinctive cinematic characteristics that filmmakers and photographers seek from this format. The entire set is built around manual focus operation, giving shooters precise, tactile control over their focusing without any autofocus mechanism.

All four lenses share a common f/2.8 maximum aperture, ensuring consistent exposure and depth-of-field behavior as you move between focal lengths during a shoot. A unified 67mm filter thread across the collection makes it straightforward to use the same filter set or matte box on every lens without swapping adapters. The full set weighs 707g combined, keeping the overall package relatively portable for a multi-lens anamorphic kit.

Designed exclusively for the Micro Four Thirds mount, the collection integrates directly with any compatible mirrorless body. There is no image stabilization in any of the lenses, so shooters will rely on in-body stabilization where available. For content creators working in the MFT ecosystem who want a cohesive anamorphic prime set with matched optics and shared accessories, this collection offers a unified solution across the standard focal length range.

Description — Sirui 1.33x Anamorphic Lens Collection for MFT

The Sirui Mars Anamorphic Lens Collection for Micro Four Thirds is a matched set of four anamorphic prime lenses covering 24mm, 35mm, 50mm, and 75mm focal lengths. Designed exclusively for the Micro Four Thirds mount and mirrorless camera systems, each lens delivers the characteristic look associated with anamorphic optics. All four lenses share a f/2.8 maximum aperture, providing consistent rendering and exposure behavior across the entire set.

Focus is manual on every lens, with no autofocus available, giving the shooter direct, deliberate control over focus — well suited to cinematic and video applications. A unified 67mm filter thread runs across all four lenses, simplifying accessory use whether you're working with ND filters, matte boxes, or other front-of-lens tools. The complete collection weighs in at 707g total. Image stabilization is not present in any of the lenses, so body-based stabilization should be considered when selecting a compatible camera.

With focal lengths spanning the standard range and anamorphic optics throughout, this set is built for MFT shooters who want a cohesive, matched prime lineup for cinematic work.
