The OptMore TL-FFX14 1.4x Extender from Musashi Optical System is designed for full-frame/large-format sensor cinema cameras and lenses with industry-standard PL mounts. A new system of AR multicoated optics is designed to effectively increase the focal length of the lens by a factor of 1.4x while maintaining the highest level of image quality.
The OptMore 1.4x extender has the advantage of only reducing the light passing through by just one T-stop, while effectively magnifying the focal length of the taking lens. This provides for a narrower field of view while maintaining the character and unique optical quality of the taking lens. The FFX14 is designed with precision in both optics and mechanics. The body of the FFX14 is anodized aluminum, while both PL mounts are stainless steel for durability.
