Canon Patent: In Body Image Stabilization For EOS M Or PowerShot Camera

Canon Patent

After all those Canon patents referring to RF mount lenses, here is a different one: IBIS on a small camera body.

Canon patent application US20210105391 (USA) discusses In Body Image Stabilization (IBIS) for a small camera body. According to the drawings in the patent literature it’s either an EOS M camera or a PowerShot camera. IBIS coming to the EOS M system is already rumored. This patent seems to consolidate it.

This one looks more like a PowerShot camera

Canon Patent: Various Telephoto Zoom Lenses For The RF Mount

Telephoto Zoom

And here is another Canon patent application for telephoto zoom RF mount lenses. No doubt left that Canon is heavily investing in the EOS R full frame mirrorless system.

Canon patent application P2021-56407A (Japan) discusses optical formulas and designs for a bunch of telephoto zoom lenses for the RF mount. However, one of the optical designs listed below is for an APS-C sensor, so either for the EOS M (likely) or for Canon’s crop sensor DSLR lineup. The patent application was spotted by Hi Lows Note.

Canon EOS R5 Firmware Review (version 1.3.0, C-Log 3 gamma, Raw lite, 1080/120p)

Canon EOS R5 Firmware Update Sony A7s Iii

Guess this is something we might get used to: reviews of firmware updates. Here is a Canon EOS R5 firmware review.

DPReview TV reviews the Canon EOS R5 firmware as of version 1.3. Under scrutiny are the new C-Log 3 gamma profile, the 1080/120p footage, and the new Raw lite video codec. Enjoy.

More Canon EOS R5 review stuff is listed here, for EOS R6 review stuff see here. The EOS R5 is highly regarded as a stills camera. In particular, the EOS R5 autofocus system seems to be huge leap forwards. User manual are available for download for the EOS R5 and the EOS R6.

Canon Announces A New 4K Portable Zoom Lens, The Canon CJ17ex6.2B

Canon CJ17ex6.2B

Is there a reason Canon’s broadcast lenses have to have such names? There is a new 4K portable zoom lens: the Canon CJ17ex6.2B

Canon press release:

Canon U.S.A. Bolsters the Company’s Industry-Leading1 Number of UHDgc 4K Portable Zoom Lenses With The Introduction Of The New CJ17ex6.2B

The New Lens Features a 17x Zoom, Built-In 2x Extender, Cleverly Designed Lens Barrel and Coating to Help Reduce Ghosting and Flaring

MELVILLE, NY, April 7, 2021Designed to provide both stunning HDR imagery as well as beautiful 4K, Canon U.S.A., Inc., a leader in digital imaging solutions, is introducing a new addition to its cost-effective UHDgc series of portable 4K broadcast zoom lenses — the CJ17ex6.2B. This lens supports 4K UHD quality optical performance and provides operators with a compact, lightweight, and highly portable form factor for easy integration into Houses of Worship, ENG, and commercial environments. With the addition of this lens, Canon further expands its lineup of 4K broadcast lenses, now at an industry-leadingi 18 models.

The CJ17ex6.2B features a wide-angle focal length of 6.2 mm and a 17x zoom ratio that brings the telephoto focal length up to 106 mm. The lens is also equipped with a built-in 2x extender that enables users to quickly double the focal length up to 212 mm while maintaining amazing image quality and fine details. The lens utilizes UD (Ultra-low Dispersion) lens elements, optimally arranged in a Canon proprietary optical configuration, providing superb color reproduction to the image’s peripheral areas by enabling the suppression of potential chromatic aberrations such as color bleeding and fringing. Special lens coatings on all elements combine with a number of optomechanical strategies on the interior of the lens barrel to help reduce ghosting and flaring. Like all Canon 4K lenses, the CJ17ex6.2B comes standard with a drive unit that contains 16-bit absolute value encoders for smooth cooperation with CG environments, as well as three 20-pin connectors for easy integration into virtual and robotic systems. In addition, the lens supports HDR and WCG compatible color gradation, producing images rich with vivid colors and details.

The CJ17ex6.2B lens is easy to maneuver and shoulder, with its compact and lightweight design, weighing approximately 4.78 pounds and measuring approximately 6.49 inches (w) x 4.31 inches (h) x 9.46 inches (l) in size. The lens itself is designed with optimally located handgrips to help minimize operator fatigue when shoulder-mount recording.

The CJ17ex6.2B 4K UHD portable zoom broadcast lens is scheduled to be available in June 2021*. For more information, please visit,
