A patent for an optical formula showing  a wide angle zoom lens for a full frame mirrorless body has appeared.


It looks like this patent is for a 16-30mm f/2.8 and has a short backfocus of 11.34mm, which tells us it’s not for a DSLR.


Canon 16-30mm f/2.8 Specifications: (Japan Patent Application 2018-077320)



  • Zoom ratio: 1.67

  • Focal length: 16.48-27.44mm

  • F number: 2.88

  • Half angle: 52.70 – 38.25

  • Image height: 21.64mm

  • Back focus: 12.33 – 10.00mm

Is this the first sign they could be dropping EF mount? So far almost every lens rumour favours EF.

Not every patent turns into a lens.

There's the electronic side of EF, and there's the mechanical (= throat diameter & flange distance) side of EF. Canon might have the FF mirrorless have EF electronics, EF throat diameter, and a shorter flange distance, which would allow mounting all existing EF lenses with an extension tube.

There is also still a possibility of a recessed mount that is EF compatible.

No, there have been several patents that were FF mirrorless related over the past few years, lenses, including a EF- new lens mount converter.  We know what the news lens mount will likely look like, assuming that Canon decides to go with it, which looks likely.

This patent is the latest of several signs that Canon is exploring the design of a new mount for mirrorless fullframe camera.  Even if Canon does bring out a FF Mirrorless camera with a new mount, that does not mean that Canon will "abandon the EF mount".    In the first place it will keep making DSLR cameras.  In the second place, it may bring out mirrorless models that have the EF mount, depending on how the market develops.

I like how likely how the mirrorless will have a mount like the design that I like!   ;D

Not every patent turns into a lens.

It seems like every week there are one or more lens patents.... it has to be less than ten percent of them that result in a lens being made.
The best camera is the one in your hands

Somebody's facetious radar is down.  We can wait to sell until the fall.
