Sirui's anamorphic prime for MFT — the 35mm f/1.8 creating cinematic widescreen images.
The Sirui 35mm f/1.8 1.33x Anamorphic is a cinema-oriented prime for Micro Four Thirds cameras that produces genuine anamorphic widescreen images. Unlike conventional widescreen crops, anamorphic lenses squeeze a wider field of view onto the sensor, providing the distinctive horizontal lens flares, oval bokeh, and cinematic look associated with Hollywood productions.
The 1.33x anamorphic squeeze combined with the MFT 2x crop factor creates an effective widescreen ratio. The f/1.8 aperture provides good low-light capability. The anamorphic characteristics — horizontal flares, oval bokeh, and distinctive rendering — are the creative selling points. Sharpness is good in the centre with some softening at the edges typical of anamorphic designs.
Micro Four Thirds mount. Filter thread is 67mm — consistent across Sirui's anamorphic set. Weight is approximately 460 grams. Build quality is cinema-grade with geared focus ring for follow-focus systems. De-clicked aperture for smooth iris transitions. Manual focus only. The lens requires de-squeeze in post-production to achieve the correct aspect ratio.
Available on the used market at moderate prices — significantly more affordable than professional cinema anamorphic lenses. Check for smooth geared ring operation. An extraordinary creative tool for filmmakers wanting authentic anamorphic characteristics on MFT cameras. The matching 24mm and 50mm complete a compact anamorphic set.
