Sirui's MFT anamorphic — the 50mm f/1.8 1.33x for MFT widescreen cinema, same concept as ID 3676.
The Sirui 50mm f/1.8 Anamorphic 1.33X is a compact anamorphic prime from Sirui for Micro Four Thirds cameras, applying a 1.33x horizontal squeeze to produce a widescreen 2.35:1 aspect ratio when de-squeezed in post-production. The 50mm on MFT gives a 100mm full-frame equivalent with anamorphic characteristics.
The lens delivers 50mm (100mm equivalent on MFT) at f/1.8 transmission aperture with 1.33x anamorphic squeeze, horizontal lens flares, oval bokeh, manual focus and aperture operation, and MFT mount.
Sirui's 1.33x anamorphic lenses made the cinematic anamorphic aesthetic accessible to MFT mirrorless filmmakers at a fraction of professional anamorphic lens costs. The 100mm equivalent focal length on MFT provides strong portrait compression with the anamorphic rendering characteristics prized in narrative filmmaking.
Check focus ring smoothness for precise manual focus. Verify horizontal flare characteristics. Test anamorphic squeeze uniformity. Inspect front element for coating integrity — flare character depends on it.
