Sirui 50mm f/1.8 Anamorphic 1.33x Lens (MFT Mount) Review

The Sirui 50mm f/1.8 Anamorphic 1.33x is a landmark lens, single-handedly making the coveted anamorphic look accessible to a new generation of filmmakers. For years, the distinct horizontal flares, oval bokeh, and cinematic widescreen format were the exclusive domain of high-end productions. This lens changed the game by delivering those core characteristics in a competent package at an unprecedentedly low price point. It's not simply an effect filter; it is a true anamorphic optic that provides authentic, characterful results that elevate productions far beyond what a spherical lens can offer.

Of course, reaching this price involves some practical compromises. The 1.33x squeeze is more subtle than the 1.8x or 2x squeeze factors found on professional cinema lenses, resulting in less pronounced anamorphic traits. Optically, it's not the sharpest lens on the market, especially when shooting wide open at f/1.8, but its softness and unique flare patterns are arguably part of its charm. The full manual control also requires a more deliberate shooting process. These are not so much flaws as they are understandable trade-offs for the incredible value offered. For what it is, the build quality is surprisingly robust and the user experience is straightforward for anyone familiar with manual lenses.

Ultimately, this lens has earned its reputation as the go-to starting point for budget anamorphic filmmaking. It provides a genuine cinematic tool that encourages creativity and adds immense production value. While more expensive options will offer greater sharpness and a more extreme anamorphic effect, the Sirui 50mm delivers an experience and a final look that punches far, far above its weight class.
