Sirui SIRUI 50mm T2.9 1.6X Full-Frame Anamorphic Lens Review

This lens is a one-trick pony, but that trick is cinematic magic. The Sirui 50mm T2.9 1.6X Anamorphic is built for one thing: giving your footage that classic, widescreen movie look without a Hollywood budget. It's heavy, manual focus only, and not exactly versatile, but if you're chasing that specific anamorphic vibe—the horizontal flares, oval bokeh, and ultra-wide aspect ratios—this is your most accessible ticket in.

The optical performance is surprisingly sharp for the price, landing in the 93rd percentile. The built-in image stabilization is also a huge plus, sitting at the 89th percentile and helping keep those cinematic shots steady. But the real story is the 1.6x squeeze. It transforms a standard 16:9 video into a dramatic 2.8:1 aspect ratio, which is instantly more immersive. Just don't expect speed; the autofocus is manual-only, which is reflected in its 47th percentile ranking.

At around $449, the value proposition is crystal clear. You are paying for the anamorphic optical design and stabilization, not for versatility or speed. Compared to renting or buying professional anamorphic lenses, this is a steal. But compared to a standard autofocus prime lens at this price, you're getting a very different, more niche tool.

Don't compare this to standard primes like the Viltrox 35mm f/1.7. That lens is about autofocus speed and a bright aperture for photos. The Sirui is for video. A closer competitor might be the Meike 55mm F1.8 Pro, which offers full-frame autofocus and a brighter aperture for stills, but it doesn't give you the anamorphic look. The Sirui's real competition is other entry-level anamorphics, and in that space, its combination of optical performance, 1.6x squeeze, and built-in stabilization is hard to beat for the money.

Buy this lens if you shoot video and you're obsessed with getting a cinematic anamorphic look on a budget. It's a purpose-built tool that does its one job very well. Skip it entirely if you need autofocus, shoot mostly photos, or want a lightweight, versatile walk-around lens. For the right filmmaker, this is an easy recommendation.
