B4 2/3" to Sony E-mount Package

An original design by Mike Tapa and Alister Chapman.

The B4 2/3" broadcast lens to Sony E-mount package is a useful way of utilising all of your B4 mounted lenses on Super 35 E-mount cameras such as the NEX FS-100, FS-700, FS7 and FS5

By detaching the E-mount from the rear of the package, it can also be used on APS-C sized sensor cameras such as the Canon 7D and the Canon C300, as well as the Canon 1D C and the new Sony A7s (both when used in Super35 crop mode only).

  • Solid all aluminium construction.
  • Chrome plated Canon EF mount.
  • Multi layer coated optics.
  • Complete with MTF Canon EF to Sony E-mount adaptor.
  • Complete with support bridge.
  • Complete with Canon front and rear caps.

(Can only be used on B4 2/3" lenses with built in 2X extender engaged. HD lenses recommended)
