The world of cinema lenses continues to evolve, with filmmakers increasingly demanding smaller, more versatile lenses without compromising optical performance. In response to these demands, Thypoch introduced the Simera-C Line earlier this year to try to meet those needs. Originally released as stills lenses in various mirrorless and Leica M mounts, they transitioned over for use in cinema. And now they continue to the transition by adding the new 21mm T1.5, expanding its already impressive range of cine primes. This new ultra-wide-angle lens joins the Simera-C lineup, which already includes the 28mm, 35mm, 50mm, and 75mm models. With its compact design, cinematic aesthetics, and exceptional performance, the Simera-C 21mm T1.5 promises to be a valuable addition for filmmakers and content creators alike.
Key Features of the Simera-C 21mm T1.5
Thypoch has created a lens that combines innovative optical engineering with a design philosophy that emphasizes practicality and artistry. There’s a character to the Simeras that I find myself favoring quite a bit. There’s a blanket softness that smoothens out the entire image. Not in a bad way by any means. In fact they make the images feel somewhat surreal.

The Simera-C 21mm T1.5 is designed to maintain the consistent look and feel of the existing Simera-C primes, which includes the 28mm, 35mm, 50mm, and 75mm lenses. All Simera-C lenses share the following key features:
- 16 aperture blades for smooth, rounded bokeh.
- 210° focus control throw for precise focus adjustments.
- A 67mm front diameter to match majority of the Simera-C lineup.
- Dual focus scales in both metric and imperial units for easy, consistent focusing.
These shared characteristics ensure that the Simera-C 21mm T1.5 will pair seamlessly with the other lenses in the series, offering consistency across a range of focal lengths.
Close Focus and Detail Capture
The Simera-C 21mm T1.5 features a minimum focusing distance of just 0.23 meters, the closest of any lens in the Simera-C lineup. This makes it perfect for capturing intricate details or for close-up shots, all while maintaining impressive optical clarity. Whether you’re filming wide vistas or tight corners, this tiny lens is veritable Swiss army knife.
Smooth Focus Control
With its 210° focus throw, the Simera-C 21mm T1.5 allows for smooth, controlled focus pulls. It’s not the longest focus throw in the world and definitely less so than something like the NiSi Athenas, but it’s more than enough to dial in when you are racking between subjects. Whether you’re focusing on a subject at a distance or capturing fine details in close-up shots, the lens provides precision control that allows you to achieve your creative vision with ease.

Cinematic Optics for Storytelling
One of the standout features of the Simera-C 21mm T1.5 is its exceptional optical design, inherited from the previous Simera-C lenses. The 21mm delivers sharp images with a subtle touch of softness, perfect for cinematic storytelling. Its natural look avoids overwhelming the scene, ensuring that the focus remains on the subject. The bokeh is creamy and rounded, thanks to the 16 aperture blades, and the lens controls flare with precision, delivering controlled highlights that enhance the image without distractions.

The Simera-C 21mm T1.5 delivers high-quality results thanks to a carefully engineered optical design. The lens uses 2 aspherical elements, 3 low-dispersion elements, and 3 high-refractive-index elements to reduce common optical issues like chromatic aberrations and flare. This design ensures excellent resolution across the entire image, from center to edge, while maintaining a pleasing, natural softness that enhances the storytelling aspect of your visuals. As well engineered as it is, there is still some driving character to it that helps it stand out from a lot of the other lenses in this price point.
Versatility in a Compact Package
Despite its impressive performance, the Simera-C 21mm T1.5 is incredibly compact, measuring only 78.6mm in length and weighing just 491g. This makes it perfect for handheld shooting or gimbal setups, particularly when paired with platforms like the DJI Ronin 4D. Its lightweight and robust design allow it to be used in a variety of scenarios, from tight indoor spaces to wide outdoor landscapes, without adding unnecessary bulk to your rig.
