Our editorial take on the Sirui 35mm f/1.8 Anamorphic 1.33x Lens (MFT Mount)
The Sirui 35mm f/1.8 Anamorphic lens fundamentally changed the landscape for budget filmmakers using the Micro Four Thirds system. It effectively democratized a cinematic look that was previously reserved for high-end productions or those willing to wrangle with cumbersome adapters. By offering a self-contained, affordable, and surprisingly sharp anamorphic solution, Sirui provided a critical entry point for creators wanting to experiment with the format's signature aesthetic.
The lens successfully delivers the most important anamorphic characteristics. You get the classic streaking lens flares and the pleasing, oblong bokeh that immediately separate your footage from standard spherical lenses. The 1.33x squeeze factor is a sensible compromise, providing a distinct cinematic widescreen look without being so extreme that it becomes distracting. Paired with a fast f/1.8 aperture for low-light work and a commendably sharp optical performance, this lens is far more than a novelty. It's a practical and powerful tool that continues to be a go-to recommendation for any MFT shooter looking to elevate their visual style.
- Groundbreaking affordability for a dedicated anamorphic lens
- Impressively sharp image quality, even at its widest aperture
- Delivers classic anamorphic traits like horizontal flares and oval bokeh
- Fast f/1.8 aperture performs well in low light
- Compact, all-in-one design is much simpler than adapter rigs
- Solid build quality for the price point
- Manual focus only, which requires more deliberate operation
- The 1.33x squeeze factor is less dramatic than more expensive 1.8x or 2x lenses
