Reimagining the image expansion experience with a low-attenuation design, the Marlin 1.4x Extender empowers the professional cinema lens ecosystem with effortless focal length and format extension. Seamlessly breathe new life into your existing lens lineup and adapt to diverse production gear.

Marlin: Native Transparency & Clarity
Utilizing high-refractive-index SR optical elements paired with large-diameter aspherical lenses, and complemented by an internal flocked anti-reflective lining, this extender effortlessly suppresses stray light and controls chromatic aberration to maintain a rendering texture nearly identical to the lens's native quality.
With a seamless 1.4x focal length extension, you can narrow your field of view and compress spatial depth without purchasing new lenses—unlocking far more creative potential from your existing lineup.

Minimal Light Loss: Preserving Rich Textures of Light & Shadow
While increasing the focal length, light loss is strictly controlled to less than 1 stop. This ensures excellent exposure performance, delicate depth-of-field effects, and flexible lighting setups in real-world shooting—extending your reach without sacrificing creative efficiency.

Format Versatility: Effortless Coverage Upgrades
Helps Super35 lenses perfectly cover Full-Frame sensors, or directly expands your existing lens pool on Full-Frame camera bodies. This reduces gear upgrade costs and extends the lifecycle of your lens investments, all while seamlessly adapting to next-generation mounts including E, Z, L, and RF.

All-Weather Design: Built for the Elements
Built-in back-focus adjustment mechanism: Eliminates the need to detach the lens or use shims, allowing swift calibration when switching between multiple lenses or camera bodies—perfectly tailored for rental houses and high-intensity shoots.
Front and rear stainless steel mounts with precision CNC machining: Prevents metal binding and ensures long-term stability and accuracy even after repeated mounting and unmounting.
