The IB/E Universal Mount System (UMS) for Canon Cinema Zooms makes it easy for users to quickly switch between various lens mounts in the field. Of the various mount options, the first available mount was for Canon EF, but with the recent crop of new cameras, you now have the ability to use any of the popular Canon Cinema Zooms (14.5-60, 30-300, 15.5-47, and 30-105) on cameras such as the Sony a7S, Panasonic GH4, or Blackmagic Studio Camera.
When performed by one of our lens technicians, the installation is reversible and non-invasive. Our techs will also calibrate back focus and zoom center axis (zoom tracking) during this process to ensure accuracy when switching between lens mounts. The process of switching to a different mount (such as the FS700's E-mount or the Blackmagic Studio Camera's MFT mount) is easy - just unscrew the four screws in the center of the flange and remove the extension you want to switch out. (For a step-by-step look, see Jeff's previous UMS post.)
Plus, for a limited time, anyone who purchases the UMS for Canon Cinema Zooms, along with one of the compatible Canon lenses, can take advantage of free installation!
