Musashi-Opt states that the 1.4x extender utilizes a system of AR multi-coated optics that are claimed to help lenses maintain the highest level of image quality. You will lose 1 stop of light when using the 1.4x extender.
The body of the TL-FFX14 is made out of anodized aluminum while both PL mounts are stainless steel.
Please be aware that most PL-PL 2x and 1.4x extenders won’t work with every single lens, and that includes this one. It is interesting to see that Musashi-Opt did not make a version with an LPL mount.
