Key Features — Sirui 75mm f/1.8 1.33x
1.33x Anamorphic Squeeze: Captures a wider field of view that unsqueezes to a cinematic widescreen aspect ratio, producing the oval bokeh and horizontal lens flares characteristic of anamorphic photography.
f/1.8 Maximum Aperture: Allows shooting in lower light conditions and creates a shallow depth of field with the distinctive rendering anamorphic lenses are known for.
75mm Prime Focal Length: Fixed focal length delivers a consistent standard-to-short telephoto angle of view on MFT cameras, well suited to portraits and cinematic close-ups.
Micro Four Thirds Mount: Natively compatible with MFT mirrorless cameras from Panasonic and Olympus/OM System without adapters.
Manual Focus Only: Designed around a deliberate manual focus workflow common in video production, with a focus ring built for smooth, controlled pulls.
67mm Filter Thread: Standard filter diameter makes it straightforward to use ND, polarizing, or other widely available filters for exposure control and creative effects.

Description — Sirui 75mm f/1.8 1.33x
The Sirui 75mm f/1.8 Anamorphic Lens is a prime lens in the standard focal length range, purpose-built for the Micro Four Thirds (MFT) mirrorless camera system. With a maximum aperture of f/1.8, this anamorphic lens opens up possibilities for low-light shooting and creamy background separation that spherical lenses at the same focal length cannot replicate in the same way. It is a manual focus lens with no autofocus capability, aligning with cinematic workflows where precise, deliberate focus control is standard practice.
The lens features a 67mm filter thread, making it easy to pair with widely available filter systems for creative or technical filtration needs. Weighing 795g, it has a solid, substantial build that MFT shooters should consider when planning their camera rig and support system. No image stabilization is included, so shooters should plan accordingly with in-body stabilization or external support. For MFT mirrorless users looking to bring an anamorphic aesthetic to their work, this 75mm f/1.8 prime offers a compelling option in its category.
