Some new Canon patent applications, all spotted by Canon News.
Canon Patent Application 2019-184921 discusses how to further shrink the size of a mirrorless camera:
An object of the present invention is to provide a technique for suppressing an increase in the size of an image pickup apparatus due to the arrangement of a motor for driving a shutter.
Canon Patent Application 2019-186594 deals with the idea of a camera with dual sensors. Might produce some pretty cool HDR photography:
The half mirror 103 splits the imaging light beam (subject light beam) that has passed through the imaging optical system 102 into a first light beam and a second light beam. The first image sensor 104 and the second image sensor 105 receive the first light beam and the second light beam, respectively. The first image sensor 104 and the second image sensor 105 are constituted by a CCD image sensor, a CMOS image sensor, or the like. The first image sensor 104 and the second image sensor 105 have an image pickup pixel and a focus detection pixel for autofocus using a phase difference detection method. The MPU 106 includes a CPU and a memory that stores a program executed by the CPU, and functions as a control unit that controls the overall operation of the camera body 101. Further, the MPU 106 controls the driving of the photographing lens 102b via the lens driving motor 108.
Can the Canon EOS R system miss a Nifty Fifty lens? It looks like this has not to happen. Canon patent application 2019-184748 discusses optical formulas for an RF 50mm f/1.8 lens. Here comes the Nifty Fifty:

image height 21.64
total lens length 58.55
BF 20.94
Focal length 48.70

Image height 21.64
total lens length 58.55
BF 20.15
Focal length 48.70
F-number 1.85

Canon patent application 2019-0324229 discusses optical formulas for an RF 14-28mm f/2 lens for the EOS R system
Focal length 14.42 19.78 27.16
F-number 2.06 2.06 2.06
Half angle of view 56.32 47.56 38.54

BF 16.13 16.13 16.13
More Canon patent applications are listed here. Some particularly interesting patent applications we think might get into production are these:
The KamLan 50mm f/1.1 II lens for mirrorless systems has been officially released. It sells at $159.99 and can be pre-ordered at Adorama or KickStarter
The “Kamlan 50mm F1.1 MK2 APS-C lens” has a super large, bright f/1.1 aperture with 11 circular aperture iris that allows for great results in extreme low light conditions and also the ability to create beautifully creamy backgrounds. Brand new optical design can help you get great sharpness in all aperture range.
One of the key strengths of the Kamland 50mm f/1.1 MK2 is its high degree of color accuracy and richness. Unlike some normal large lenses, it does not introduce too much color cast to images but instead delivers a neutral, accurate color rendition even wide open. You can easily create great 3D effect and rich sense of atmosphere for your images.
Kamlan 50mm F1.1 MK2 features with dual high index of refraction element groups. It can calibrate the spherical aberration effectively. The result is your images will be sharp from minimum distance to infinity.
Further extending the flexibility of the lens is the ability focus down to just 0.4m (1.3ft), allowing you to fill the frame with your subject and throw the background dramatically out of focus.
Kamlan 50mm F1.1 MK2 features a larger diameter element with high index of refraction glass to help eliminate the onion rings. The whole defocus area is smooth and creamy.
Canon patent application 2019-0113711 (USA) describes the optical formula for an RF 50mm f/1.8 and RF 28mm f/1.8 lens, both for the Canon EOS R full frame mirrorless system.
Focal length 48.50 F-number 1.85 Half angle of view (degrees) 24.04 Image height 21.64 Total lens length 95.00 BF 15.80
Focal length 28.80 F-number 1.85 Half angle of view (degrees) 36.91 Image height 21.64 Total lens length 80.30 BF 7.00
It’s likely Canon will launch these non-L lenses sooner than later. Both are popular focal lengths on full frame, and it’s also likely Canon is set to offer some less expensive (aka budget) lenses for the EOS R system.
More Canon patent applications are listed here. Some particularly interesting patent applications we think might get into production in the next few years are these:
Sony E, Canon RF and Nikon Z-Mount Full-Frame Lens
Aperture Range: f/0.95 to f/16
Four Extra-Low Dispersion Elements
One Ultra High Refraction Element
Stepless, Silent Aperture Control
Manual Focus Design
Depth of Field and Distance Scales
11-Blade Aperture
Minimum Focusing Distance: 1.6′
ZY Optics released the Mitakon Speedmaster 50mm f/0.95 III for Canon RF, Nikon Z and Sony FE mounts.
Press release:
ZY Optics releases the Mitakon Speedmaster 50mm f/0.95 mark III, designed for Sony FE, Canon RF & Nikon Z cameras
Shenyang China, Apr 17, 2019 – Zhongyi Optics (ZY Optics) have released the new Mitakon Speedmaster 50mm f/0.95 version III for full frame Sony E, Nikon Z and Canon RF cameras. Offering a natural 50mm perspective along with an ultra-fast f/0.95 maximum aperture, the Mitakon 50mm f/0.95 is a compact prime characterized by its bright f/0.95 aperture to suit working in low-light conditions. It also affords a great degree of control over depth-of-field for isolating subjects from the background and producing selective focus effects. The new version III features a new optics design which offers a slightly more compact size and a better flare resistance. A carefully-designed 10 elements in 7 groups optics system with 1pc of HRI (High Refractive Index) & 5pcs of UD (Ultra-low dispersion) elements successfully minimizes the chromatic aberrations and delivers exceptional image quality. An eleven-blade diaphragm helps to produce a softly diffused out-of-focus rendering (bokeh). The enclosure of the lens is made of metal to strengthen its durability.
Pricing & Availability Mitakon Speedmaster 50mm f/0.95 III is now available to ship and purchase at ZY Optics official website (http://www.zyoptics.net/). The Recommended Retail price (before tax) is USD 799/pc.
