Further to the Hejnar PHOTO Replacement Foot for Sony FE 70-200 f/2.8 Lens with QD socket that we saw yesterday, another addition came in dedicated to another popular SONY telephoto lens The new replacement foot is intended for the Sony FE 100-400 mm f/4.5-5.6 GM OSS lens and equipped with a QD (Quick Detach) socket.
Same as its sibling the addition of a QD socket on the replacement foot not only allows for Arca compatible support, but also helps to carry safely the lens around in nature.
