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

Canon

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).

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.

Canon Patent Application for Long Eye Relief Optics in EVF

Canon Patent

Canon patent application 2018-124349 discusses optics for long eye relief (Wikipedia) in an Electronic View Finder (EVF). This is particularly useful for people wearing glasses. Otherwise they would struggle to see the whole image in the EVF. This patent application might actually go into production sooner or later.
