Canon Patent For RF 28-70mm F/2-2.8 For EOS R (with no image stabilisation, sign for IBIS?)

Canon Patent

Hi Lows Note spotted a Canon patent application (2018-197774) for an RF 28-70mm F/2-2.8 lens for the EOS R system.

  • Focal length: 28.68 – 67.90mm
  • F number: 2.26 – 2.91
  • Half angle of view: 37.03 – 17.67
  • Image height: 21.64 – 21.64mm
  • Lens length: 149.69 – 174.43mm
  • Back focus: 20.57 – 35.45mm

The interesting fact: the lens literature does not refer to an image stabilisation group inside the lens. Some people is saying this is a sign for IBIS (In Body Image Stabilisation) coming to future EOS R models (rumors already surfaced). We are not sure how to interpret this.

Canon always stated the superiority of image stabilisation in the lens. Never the less, Canon execs didn’t exclude the possibility of a future mirrorless camera with IBIS, and there are a few patents clearly discussing IBIS (patent 1 | 2 | 3).

Do you think this patent application is a clear sign of IBIS to be featured on future EOS R cameras?

Canon in an unusual move for the company already disclosed the the EOS R lens roadmap for the next years (also see this interview). The lens described in the patent application doesn’t seem to be on Canon’s immediate agenda. Keep in mind that patents are a way for companies to secure they research and development and hence their intellectual propriety. A patent application rarely means a product is coming to the market soon.

Canon Patent For Basic IBIS (In Body Image Stabilisation) Used To Correct Lens Eccentricity


What a neat coincidence. After a rumor about Canon featuring IBIS in future EOS R cameras, we can report a Canon patent application for a basic IBIS system spotted by Hi Lows Note.

The literature in patent application 2018-194766 seems to describe a basic IBIS system used to correct lens eccentricity. The image sensor can tilt in order to correct the lens eccentricity.

Machine translated excerpt:

[…] the optical instrument concerning the present invention, and its system, A camera device provided with the control means which carries out the tilt of the image sensor to an optic axis, It consists of a lens device provided with the detection means which detects the parameter to which the image formation performance of a lens is changed, The image sensor according to a parameter falls from the aforementioned lens device, information is transmited to the aforementioned camera device, and it is characterized by comprising the optical instrument which consists of the camera device in which the thing [ falling and carrying out the tilt of the image sensor to an optic axis based on information ] is possible, and its system.

As usual I’m glad for any help interpreting patent literature.


Canon Working on RF 25-300mm F/3.5-5.6 For Canon EOS R, Patent Suggests


Hi Lows Note spotted a Canon patent application (2018-180203) for a RF 25-300mm F/3.5-5.6 lens for the Canon EOS R system. The patent literature describes a compact lens. Doesn’t look like a L-grade lens.

  • Zoom ratio: 11.68
  • Focal length: 25.20 – 294.41 mm
  • F number: 3.50 – 5.60
  • Angle of view: 36.72 – 4.20
  • Image height: 18.80 – 21.61 mm
  • Lens length: 374.08 mm
  • Back focus: 21.75 mm


Here Is A Canon Patent For In Body Image Stabilisation (IBIS)

Canon Patent

Japanese site Hi Lows Note spotted the patent of the year.

Canon patent application in Japan 2018-165756 describes an IBIS (In Body Image Stabilisation) system.

The lack of IBIS was one of the criticism Canon had to face after the launch of the Canon EOS R. There have been various statements by Canon execs about how much better image stabilisation in lens is working. However, no one ever excluded the possibility Canon might feature IBIS on future cameras. At least now we know there is a Canon patent application for it. Interesting note: the picture on top is depicting a DSLR and not a mirrorless camera.

Machine translated excerpt from the patent literature:

The imaging device of the present invention is provided with an image sensor, the frame which supports the aforementioned image sensor, and the driving member which moves the aforementioned frame in the direction parallel to the imaging surface of the aforementioned image sensor, and the aforementioned vibrating member, It has a vibration portion which vibration occurs, it sees from the direction which intersects perpendicularly to the imaging surface of the aforementioned image sensor, and the vibration portion of at least one driving member overlaps the center of the imaging surface of the aforementioned image sensor.

What do you think, is Canon considering to sport IBIS on future cameras?

Canon Patent Application for 18-55mm Lens With Variable Field Curvature

Canon Patent

Japanese blog Hi Lows Note spotted another interesting patent (2018-159876).

The patent literature describes a 18-55mm lens with variable field curvature and spherical aberrations reduction.

This appears to be a lens with a design suited for an APS-C mirrorless camera. May this come to the EOS M system one day?

  • Zoom ratio: 2.88
  • Focal length: 18.58 – 53.49 mm
  • F number: 3.56 – 5.87
  • Angle of view: 36.32 – 14.32
  • Image height: 13.66 mm
  • Lens length: 126.24 mm
  • Back focus: 11.55 mm

There is a lot of buzz around patents. Mostly for nothing. Patents are foremost a way companies have to secure their R&D efforts (research and development).

More Canon patent applications are listed here. Some particularly interesting patent applications we think might get into production in the next years are these:

Canon Patent Application for 360 degree camera with 8 zoom lenses

LetsGoDigital spotted a rather interesting patent.

The patent literature describes a professional spherical camera system, consisting of multiple cameras that can capture 360 degree images and panorama images.

The eight cameras (one at the bottom and at the top and six divided over the middle axis) are continuously connected to each other. Each camera can zoom individually. They are configured in such a way that the field angle overlap each other, which benefits the stitching process.

As soon as the camera system is switched off again, the eight lens barrels will be closed automatically, so that they remain protected against external influences. A power switch is positioned on the top of the device, as well as a shutter release button and two zoom buttons. The zoom buttons can control one or more cameras at the same time. It is also possible to remotely operate the system via a PC or smartphone.

The Canon 360-degree camera comes with three built-in tripod legs, which can be adjusted individually both in length and angle. In addition, three movable illumination units are installed on the camera system. The battery compartment is located in the lower part of the camera.
