DZOFILM EF-Mount Tool Kit 4-Pack
This four-pack tool kit is built for owners of DZOFILM Vespid, Catta Ace, or Gnosis lenses who need to convert them to an EF mount. It supplies the hardware required to adapt each lens for use with EF-mount cinema or mirrorless cameras. The kit is intended for professionals and enthusiasts who maintain a consistent lens lineup across different camera bodies. It is not for users who own lenses outside the three named series or who require a different mount standard.
EF bayonet and shim set for precise flange
The decisive specification is the included EF bayonet combined with a shim set, which together set the correct flange focal distance for each converted lens. Accurate shimming preserves infinity focus and image quality across the frame. Without the ability to fine-tune this distance, the adapter would not deliver reliable optical performance. The kit provides the specific components needed to achieve that calibration on every supported lens.
Screwdriver included for straightforward
Installation uses the supplied screwdriver to attach the bayonet and insert shims, a process that can be completed at a workbench without specialised tools. The most common issue is selecting an incorrect shim thickness, which results in focus shift or the inability to reach infinity; users should verify focus at multiple distances after assembly. Port caps protect the mount when the lens is off the camera.

Questions about this item
How does the 4-pack EF bayonet kit change a Vespid, Catta Ace or Gnosis lens when it is mounted on an EF-mount camera?
It converts the lens to a native EF mount so the camera controls aperture and focus electronically, keeping the original image circle and focal length intact.
What does the EF-mount interface on these bayonets actually connect to on the camera side?
The bayonets lock into any Canon EF or EF-S mount body, passing electronic aperture and focus signals without an adapter in between.
What physical items are inside the box to install and shim one bayonet onto a lens?
Each of the four sets supplies an EF bayonet, a port cap, a full shim assortment for flange-depth tuning, and a dedicated screwdriver for the mounting screws.
