Canon Working on Lens Driving Adapter


Canon latest patent shows that they are working on a Lens Driving Adapter possibly for EF and EF-S Lenses. It will going to attach on the side of the lens to do the zoom operation by rotating the lens barrel.

Before we begin let me tell you that the Canon PZ-E1 zoom adapter was announced sometime in Feb 18 2016 and that works only with Canon 18-135mm IS USM (Nano) Lens.  But this patent was filed on June of 2016 and it was first published on Jan 5, 2017. Hence Canon may be working on improved and versatile version of its current PZ-E1 zoom adapter .

Patent Details (Translated)
The lens driving adapter is detachably attachable to a lens barrel on which an operation member is provided. The adapter includes a driver configured to drive the operation member, and an adapter body holding the driver. The adapter body includes a first contact portion and a second contact portion that are protrusions contactable with two circumferential portions in an outer circumferential surface of the lens barrel. The first and the second contact portions are contactable with outer circumferential surfaces of lens barrels whose outer diameters are mutually different. The adapter body includes a fixing member configured to fix the adapter body to any of the lens barrels.

    Well I am glad that you published this patent, I have the privileged to use it prior to its announcement.

    Actually The patent you are showing is of IInd generation PZ-E1 power zoom adapter.

    The first gen of powerzoom adapters was introduced on Feb month of 2016.

    The first generation of adapters are available but only compatible with EF-S 18-135mm IS USM Lens (Nano USM).

    Thanks Steve for your input

    Puzzling product.
    The controls suggest that the device powers the zoom, using a manual toggle.
    How this improves on just turning the zoom collar manually is not clear.
    What am I missing?

    I don’t think the we need these things. Canon should concentrate on some more important.. for example do they working on in-camera IS system? Since all major mirrorless makers offering DUOS IS.
