The M-mount holds a significant place in the history of still photography lenses. The Simera-C draws inspiration from legendary M-mount rangefinder lenses of the past, inheriting their unique atmosphere and texture—a vintage sentiment woven from optical imperfections and softness. The Simera-C 100mm features a 0.85m minimum focusing distance, providing a more ample working distance for telephoto close-ups and turning subtle performance details into the narrative essence brimming with tension.



The M-mount Simera-C can be adapted to ARRI cinema cameras using a third-party ARRI mount adapter. For compatibility, we recommend XPIMAGE's ARRI mount for Simera-C. This ARRI M mount is compatible with the following ARRI camera models: Alexa 35, Alexa Mini LF, Alexa Mini, and Amira.

The Simera-C (E and M) can be used with the DJI Ronin 4D by simply switching the mount of Zenmuse X9 without needing counterweights.
All elements are manufactured with micron-level precision and combined milling processes, minimizing optical aberrations like chromatic aberration. This ensures consistent imaging across all focal lengths—delivering uniform center-to-edge sharpness for high-end productions.
With unified mechanics and consistent color, the Simera-C covers everything from dramatic wide angles and natural standard narratives to refined telephoto close-ups. Ultra-lightweight yet versatile, it is the ultimate choice for solo creators and lightweight crews.

FAQ
How can the Simera-C lenses be adapted for autofocus with the DJI Ronin 4D?
Follow DJI's official calibration process for calibration. If focusing issues occur, we recommend adding more calibration focus points, as this step typically helps the system better recognize the focus target, improving focus accuracy.
Can the Simera-C lens fit an 80mm standard cine matte box?
Yes, the Simera-C 21mm, 28mm, 35mm, and 50mm lenses have a 62mm filter thread, and can use a 62mm-82mm filter adapter ring to be compatible with an 80mm matte box. The 75mm lens has a 67mm filter thread and can use a 67mm-80mm filter adapter ring to be compatible with an 80mm matte box.
Does the Simera-C lens have electronic contacts?
No, the Simera-C series does not have electronic contacts.
Are Simera-C lenses compatible with ARRI cinema cameras?
Yes, they are compatible with ARRI cinema cameras using the XPimage Leica M to ARRI locking adapter.
