Being modest for storytelling

Being modest for storytelling

Over the past few years, cinema cameras have become remarkably smaller, driving the demand for compact, high-performance cine lenses. The Simera-C responds to this need by blending the design legacy of classic rangefinder lenses with DZOFILM’s cinema DNA and cutting-edge optical technology. This fusion achieves a perfect balance between the precision of still photography and the cinematic quality of motion picture imagery within an incredibly compact form.

Simera-C delivers beautifully smooth bokeh and natural edge fall-off, offering exceptional dimensionality for storytelling. It captures a raw and naturalistic aesthetic with clean chromatic aberration control and human-eye-like field curvature even at wide open. The flare is subtly managed to capture highlights without overwhelming the image, keeping the storytelling pure and authentic.

The floating element design throughout the Simera-C series enables a closer minimum focusing distance than most rehoused or modified rangefinder lenses. This allows filmmakers to capture greater texture and detail in close-up shots, providing enhanced creative flexibility and depth.

Constant T1.5 Aperture for Cinematic Depth

The Simera-C series offers focal lengths of 21mm, 28mm, 35mm, 50mm, and 75mm, covering a spectrum from wide-angle to medium telephoto to suit various shooting scenarios. With a constant T1.5 aperture throughout the series, these lenses excel in diverse lighting conditions. The ultra-shallow depth of field adds dramatic depth and spatial separation to each frame, while the ample light intake supports high-frame-rate shooting, ensuring rich tonality and texture even in low-light environments. Each image captures emotion and poetic nuance, embodying the essence of cinematic storytelling.

With a meticulously crafted optical structure that incorporates aspherical lenses, low-dispersion elements, and high-refractive-index elements, Simera-C achieves outstanding resolution and exceptional chromatic aberration control, supporting 8K high-resolution production. The aperture blades have been increased from 14 to 16 compared to the Simera photography series, producing smoother, rounder bokeh and minimizing "onion rings" or irregular highlights. This natural and soft background blur enhances image purity and elevates the artistic aesthetics of every shot.

High Contrast for Dramatic Depth

High Contrast for Dramatic Depth

The creamy bokeh and moderate high-contrast render the layers of light and shadow with intricate detail, with a striking contrast between highlights and shadows that accentuates the subject, adding dimensionality and spatial depth to the frame. Simera-C is perfectly compatible with high-resolution digital cinema cameras that provides broader dynamic range and rich textures, enhancing the flexibility of post-production.

Simera-C utilizes advanced vacuum coating and multi-layer anti-reflective coatings to minimize reflections and suppress flaring and ghosting, delivering accurate color reproduction even in backlit conditions. The internal anodized matte-black finish keeps reflectivity below 3.5%, significantly reducing internal stray light reflections. This superior anti-glare capability ensures pristine image quality under complex lighting, capturing both highlights and shadows with impressive clarity, contrast, and depth.

Lightweight Durability, Unrestricted Mobility

Crafted from aerospace-grade aluminum alloy, the all-metal body of the Simera-C series balances strength and lightness. Each lens weighs between just 380-470 grams, slightly heavier than a 330ml soda can but with a more compact form. This breaks free from the traditional constraints of cinema lenses regarding size and weight, allowing seamless use across handheld, gimbal, or drone setups. The internal dust and splash-resistant design ensure reliable performance even in the most challenging shooting environments.

Streamlined for Effortless Creativity

The compact design reduces reliance on heavy cinema accessories and lightens the load for filmmakers. Multiple focal lengths can be easily packed and carried, making Simera-C particularly suited for travel shoots and documentary work where mobility is key. When paired with auto-focus systems like DJI Focus Pro, operational demands and crew burden are lightened, offering enhanced agility for solo operators and small production teams.

Modular System Integration, Expanding Creative Boundaries

The ultra-compact design of the Simera-C makes it one of the few cinema lens sets compatible with the DJI Ronin 4D. When integrated with the DJI FLEX system, complex setups like low-angle, over-the-shoulder tracking, or tight interior car shots become easy to execute. This compatibility enriches the visual storytelling, enhancing the mobility, operability, and creative freedom on set.

Precision Consistency, Seamless Operation

The entire series features a 0.8 MOD gear pitch for both focus and aperture rings, ensuring compatibility with common follow focus systems and cinema accessories. The consistent gear positioning allows for lens and accessory swaps without the need for recalibration. The 28-50mm lenses have the same length, while the 21mm and 75mm lenses are slightly longer. With similar lengths and weights, lens swaps on stabilizers or sliders are smooth, reducing the need for rebalancing and boosting shooting efficiency.A 210° focus throw offers ample precision for manual focus, with smooth, controlled operation allowing for subtle focus pulls or precise shallow depth-of-field control.

The M mount represents a significant chapter in the history of still lens evolution. Simera-C is inspired by some of the most legendary M mount rangefinder still lenses, inheriting their unique mood and texutre—a kind of mysterious atmosphere created by optic imperfections mixing with softness.

The compact size, lightweight design, and exceptional quality of the Simera-C make it the perfect tool for capturing stunning motion images in any mobile setting.

Short flange distances are the future. Designing lenses based on the M mount's flange distance of 27.8mm not only makes them significantly smaller and lighter compared to mounts with longer flange distances, like the PL mount at 52mm, but also allows for remarkably similar image quality.

M-mount offers versatility comparable to PL-mount

With standard M-mount adapters, Simera-C lenses can adapt to various mirrorless cameras (E, RF, Z, L, X mounts) for cross-system use. With a locking M-ARRI adapter, they are also compatible with ARRI ALEXA Mini LF, ALEXA Mini, AMIRA and other ARRI systems. This exceptional compatibility makes it easy to work with everything from entry-level mirrorless cameras to high-end cinema rigs like DJI Ronin 4D, Sony Venice, ARRI, and more.

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.

Refined Techniques for Superb Imagery

Each Simera-C lens undergoes rigorous quality control, crafted with micron-level precision using a combined milling process. This ensures exceptional manufacturing accuracy for each element, reducing optical aberrations like chromatic aberration and astigmatism. The entire series maintains consistent image quality, delivering uniform sharpness from center to edge, whether capturing wide-angle or telephoto scenes, meeting the demands of high-end production.
