Canon Patent: 30-90mm f/1.5, 18-45mm f/1.5, 70-210mm f/2.5 Cinema Lenses

Canon Patent

A new Canon patent and for once it doesn’t refer to RF mount lenses but for Cinema optics: 30-90mm f/1.5, 18-45mm f/1.5, 70-210mm f/2.5.

Canon patent application 2022119007 (Japan) discusses optical formulas for three lenses we think are Cinema or broadcasting lenses:

  • 30-90mm f/1.5
  • 18-45mm f/1.5
  • 70-210mm f/2.5

From the patent literature:

To provide a zoom lens that is advantageous in terms of, for example, a large aperture, small size and light weight, and high optical performance over the entire zoom range.

The lens diameter of the lens group closest to the object side in the first lens group is determined by the off-axis ray at the wide-angle end, and the lens diameter of the lens group closest to the image side in the first lens group is determined by the on-axis ray at the telephoto end. Therefore, if the first lens group is thickened, the size of the lens will increase if the aperture is to be further increased. In the zoom lens of Patent Literature 1, since the first lens group is thick, the zoom lens may become large if it is intended to accommodate a large-format sensor such as a Super 35 format or a full-frame format while maintaining the F-number.

Example 1

  • Focal length: 31.20-89.85
  • F-value: 1.51
  • Half angle of view: 25.38-9.35
  • Total length: 284.23
  • Back focus: 39.00

Example 2

  • Focal length: 21.00-80.57
  • F-value: 1.51
  • Half angle of view: 35.17-10.41
  • Total length: 288.03
  • Back focus: 39.00

Example 3

  • Focal length: 18.01-45.01
  • F-value: 1.51
  • Half angle of view: 39.422-18.20
  • Total length: 308.88
  • Back focus: 39.00

Canon EOS C200 Mark II Set To Get Released In 2023 (with switchable EF/RF mount)?

Cinema EOS C200

Canon might release a replacement for the Canon EOS C200 soon, i.e. next year.

Latest murmurings have it that Canon might release the Canon EOS C200 Mark II in 2023. It seems the Canon EOS C200 Mark II will have “the ability to easily switch between EF and RF mounts. We’re told that the EF mount comes off to reveal the RF mount“. A first set of specifications also leaked:

  • Same image sensor as the Cinema EOS C300 Mark III
  • Same connection ports as the Cinema EOS C300 Mark III
  • Compatible with Cinema EOS C300 Mark III and Cinema EOS C500 Mark II accessories
  • Timecode
  • SDI Terminals
  • Easily interchangable EF and RF mount
  • Same frame rates and resolution as the Cinema EOS C300 Mark III

Unfortunately, this is a long running rumor so I’d take it with a grain of salt.

Stay tuned…

Canon Announced New Flex Zoom Lens Series For Cinema With T2.4 Aperture

Flex Zoom

Canon announced the new Flex Zoom Cinema lens series: Canon CN-E 20-50mm T2.4 LF and CN-E 45-135mm T2.4 L F/FP lenses. Preorders start at $21,999.

Canon press release:

Canon Announces New Flex Zoom Lens Series of EF Cinema Lenses with Wide T2.4 Aperture Designed for Full-Frame Cameras

MELVILLE, NY, April 12, 2022Canon U.S.A., Inc., a leader in digital imaging solutions, announced today the launch of a new series of lenses for the company’s EF Cinema Lens lineup — the Flex Zoom Lens series of lenses, which were developed to create cinema-style productions with greater workflow efficiency. The first lenses in the series are the CN-E20-50mm T2.4 L F/FP wide-angle zoom lens and the CN-E45-135mm T2.4 L F/FP telephoto zoom lens.

Designed in the pursuit of cinematic beauty, the new large-aperture lenses feature both high-level optical design and performance while maintaining the style and ease-of-use of Canon’s EF Cinema lens series. With the introduction of the zoom lenses featuring focal length ranges of 20-50mm for wide-angle and 45-135mm for telephoto, Canon now offers zoom lenses that cover the same range as its six existing prime (single focal length) lenses. The versatility of these new lenses supports efficient production workflows for a wide range of scenarios, including film, TV programs, commercials, and much more.

When paired with full-frame or large-format cameras, these lenses fully leverage the cameras’ signature shallow depth-of-field look and provide smooth and natural background blur, helping to produce powerful storytelling imagery. The lenses also maintain a bright T2.4 aperture1 across their entire zoom ranges allowing for image capture in both natural light and darker environments. This feature helps to reduce the need for intricate lighting setups, enabling more efficient and cost-effective video production workflows.

Engineered with an optical configuration that creates the optimal placement of lens elements, including a large-aperture aspherical lens and an anomalous dispersion glass lens, the CN-E20-50mm T2.4 L F/FP and the CN-E45-135mm T2.4 L F/FP lenses help reduce the potential for color smudging and chromatic aberrations. This enables them to maintain high optical performance from the center of the image to the periphery when paired with 8K cameras.

In addition to supporting EF-mount data transmission2, the new lenses are also compatible with /i Technology3 from Cooke Optics. With this capability, recording metadata such as focus, zoom, aperture, and lens model can be transmitted via the lens mount for visualization on the camera itself. This additional information helps to contribute to more efficient workflows not only during on-location recording, but also during post-production and editing.

Pricing and Availability
The Canon CN-E20-50mm T2.4 L F/FP wide-angle zoom lens and Canon CN-E45-135mm T2.4 L F/FP telephoto zoom lens are scheduled to be available in early June 2022 and early September 2022 for an estimated retail price of $21,999.00.*

Canon will showcase its latest digital imaging solutions and products, including the new Flex Zoom Lens series of lenses, at the NAB Show 2022 (Booth #C4432) in Las Vegas, April 24th-27th. For more information about the new lenses and Canon’s presence at the show please visit usa.canon.com.

Canon Set To Announce New, Fast Cinema Zooms Soon?

Rf Mount Eos R6 Mark Ii Rf 300mm Rf 35mm Canon Eos R100 Rf 24mm F/1.8 Rf-s Canon Eos R7 Eos R100 Canon High Resolution Eos R R10 Eos C5 Canon Eos R1 Eos R5c Canon Rf 16mm Rf 35mm F/1.2L EF Lenses Tilt-shift Lenses Rumor

Canon might announce two new and fast Cinema zoom lenses in April 2022.

Latest rumor has it that Canon might have two Cinema zooms in the pipeline. Both lenses are said to feature a T stop of 2.0. One lens might start between 14mm and 20mm and go up between 40mm and 60mm. The other lens might start between 30mm ad 45mm and go up to 80mm-90mm.

Both lenses are designed for a Super 35mm imaging sensor but can be used with a converter.

The lenses could replace the CN 15.5-47mm and CN 30-105mm, and will be available for the EF and PL mounts.

These Might Be The Specifications Of One Of Canon’s Next Cinema Cameras (EOS C5?)

Rf Mount Eos R6 Mark Ii Rf 300mm Rf 35mm Canon Eos R100 Rf 24mm F/1.8 Rf-s Canon Eos R7 Eos R100 Canon High Resolution Eos R R10 Eos C5 Canon Eos R1 Eos R5c Canon Rf 16mm Rf 35mm F/1.2L EF Lenses Tilt-shift Lenses Rumor

We got a rumor from an unknown source. We report it as it is out of duty. Please take it with a grain of salt. Is a Canon EOS C5 coming?

We got tipped about a new, upcoming mirrorless Canon Cinema camera. A Cinema camera that seems to be closely related to the EOS R5/EOS R5 C. This is what we got:

  • The camera is a combination of the EOS R5 C and EOS C300 III, similar in appearance to the EOS R5 C, but more square, with the electric ND filter of the EOS C300 III, the professional interface of the EOS C70, and an extended battery compartment.
  • Its XF-AVC recording format is the same as the EOS C70, but it uses a modified version of the EOS R5 C’s CMOS sensor with a total of 22.5 megapixels.
  • With a sampling resolution of 8192×2160, it is capable of perfect oversampling to 4K 120fps, making it Canon’s current 4K 120fps product with the best image quality.
  • When the frame rate is reduced to 72fps or less, DGO mode is turned on to provide higher dynamic range.
  • Unlike the current EOS C70, it does not offer RAW recording for now.
  • Full pixel QPAF, and RAW internal recording in subsequent firmware.
  • In terms of photography, it no longer offers a mechanical shutter and is replaced by in-body stabilization.

The source suggested the moniker “Canon EOS C5“. Again, don’t forget the grain of salt. Please let me know what you think about this rumor. Anything to take seriously?
