E-Mount to PL Mount Pro (Sony FX6) is a shimmable Sony E-Mount to PL mount adapter that enables mounting of PL mount lenses onto the Sony PXW-FX6 camera. In our factory, we set the flange focus to match the Sony FX6; You only need to adjust the shims should you find that your camera is out of calibration. The adapter is shimmable by loosening six socket cap screws around the collar area, separating the two sections, and adding color coded shims of various thickness. Back focus should be checked using collimation tools or a wide lens focused to infinity. Mount includes a support ring that integrates with our Top Plate (Sony FX6), a highly recommended addition to this system. Loosen the support ring thumbscrew to quickly remove the mount and install another adapter. PL Cap included to prevent dust from entering sensor area when lens is not attached.This adapter will also work with any E-Mount camera like the FS7mkII, FX9, A7, A7r, A7s, A7II, FS100, FS700, NEX-5, NEX-6, NEX-7, etc, however, the support ring would not be utilized.Features: - Support ring capable of integrating with Top Plate (Sony FX6)Includes:(2) support screwsShim set (stackable to achieve necessary thickness)Silver .0127mm (0.0005")Amber .0254mm (0.001")Purple .0381mm (0.0015")Red .0508mm (0.002")Green .0762mm (0.003")Tan .1016mm (0.004")Blue .127mm (0.005")
