Canon Working On Eye Controlled Autofocus For Mirrorless Camera, Patent

Eye Controlled Autofocus
View Post

Note: we are not talking about eye-autofocus here, but about eye controlled AF. Something Canon featured already on film cameras (e.g. Canon EOS-3).

Canon parent application 2019-129461 discusses method and technology for an eye controlled AF system on a mirrorless camera. Eye controlled AF focuses, and decides where the focus point is, according to the eye position.

Canon Patent For 20mm f/1.4 and 12-24mm f/4.3-5.6 Lenses For EF Mount

Canon Patent
View Post

Hi Lows Note spotted a Canon patent application (2019-128526, Japan) describing optical formulas for a 20mm f/1.4 and a 12-24mm f/4.3-5.6 lens, both for the Canon EF mount.

20mm f/1.4 lens:

  • Focal length: 20.50 mm
  • FNo.: 1.44
  • ω: 46.54
  • Image height: 21.64 mm
  • Lens length: 134.70 mm
  • Back focus: 36.81 mm

12-24mm f/4.3-5.6 lens:

  • Focal length: 12.40 – 18.00 – 23.64 mm
  • FNo.: 4.35 – 4.96 – 5.60
  • ω: 60.18 – 50.25 – 42.47
  • Image height: 21.64 mm
  • Lens length: 142.18 – 132.82 – 131.14 mm
  • Back focus: 36.14 – 44.23 – 52.29 mm

Canon Patent For 35mm f/1.2 Lens For EOS R System

Eos R System

That’s a bit weird. After the rumor about a possible RF 35mm f/1.2L lens we spotted a patent describing such a lens. We wonder if the source of the rumor also found the patent.

Canon patent application 2019-128526 describes the optical formula for a 35mm f/1.2 prime lenses for the EOS R system. How to correct chromatic aberrations with the use of low dispersion glass is also discussed in the patent application.

And Here Is One More Canon Patent Dealing With IBIS (In Body Image Stabilisation)

Here is another Canon patent application (US 2019-0222763) dealing with IBIS (in Body Image Stabilisation).

As seen with another Canon patent about IBIS, here too the discussion is about how to make IBIS and lens IS work together smoothly. An algorithm is described that allows the camera to chose if use IBIS, lens IS, or both together.

Given all the recent Canon patent dealing with IBIS, you can safely assume that Canon will soon feature it on their camera bodies. Most likely first on the EOS R system, but there has also been a patent discussing IBIS on a DSLR.

So, IBIS is coming to the Canon universe. Sure thing.

Canon Working On Triple Image Stabilisation System, Canon Patent Suggests

Canon Patent
View Post

We already know that most likely Canon will feature IBIS (In Body Image Stabilisation) on future Canon mirrorless cameras (and maybe on DSLRs too). Canon execs confirmed it.

It seems Canon wants to do things right, as we are used to. Canon patent application 2019-0199930 (US) describes technology and methods to make three image stabilisation systems work together. The patent discusses how to combine lens image stabilisation, IBIS, and digital image stabilisation.

Another Canon patent application discusses how to make IBIS and lens IS work together smoothly.
