Canon continues to put R&D into stacked sensors. This latest patent for the technology is quite detailed in its delivery.

According to Canon News:

This patent application is for suppressing the dark current and/or leakage current by using diffusion preventing films surrounding the bonding areas.

This is a very highly detailed patent application, going into a significant amount of diagrams and specifics.  It stands to reason that Canon is heavily investing it’s time in and energy into stacked sensors, and these patents seem to indicate just that.

We’re all hoping for some sensor breakthroughs from Canon for the next generation of DSLRs and mirrorless cameras.

Sigma has released new firmware for  the following flash, mount converter and lenses.

Sigma flash and mount converter with the following firmware updates:

ELECTRONIC FLASH EF-630

• It has corrected the phenomenon where it occasionally stops communicating after recovering from Auto Power Off.

MOUNT CONVERTER MC-11

• It has become compatible with the SIGMA 70mm F2.8 DG MACRO
• It has become compatible with the SIGMA 105mm F1.4 DG HSM

We’re told that a new EF 24-70mm f/2.8L is on the horizon. The source didn’t know if the update lens would have image stabilization, or if it would be an EF 24-70mm f/2.8L III.

Previous reports peg two new “professional” lenses would be announced for Photokina, and one of the obvious lens possibilities would indeed be a EF 24-70mm f/2.8L replacement.

THe EF 16-35mm f/2.8L III and EF 70-200mm f/2.8L IS III releases have updated two of the three “holy trinity” f/2.8L zooms from Canon. While this update could be great, we can’t help but wish an IS version of the EF 24-70mm f/2.8L existed for the people that want it.

Take this with a big grain of salt for the moment and treat the [CR1] rating accordingly.

We’re told a big selling point of all future Canon prosumer camera bodies will be video capabilities. Internally Canon has had a lot of discussion about improving the perceived feature set of prosumer cameras to match the likes of Sony and Panasonic.

We consider a prosumer DSLR to be anything EOS 7D Mark II and up. That said, we don’t think Canon has anything currently we’d consider prosumer in the mirrorless space, as much as I like the EOS M5 and EOS M50. Feel free to disagree on the latter.

The source claims that Canon no longer wants to lose the “spec war” with their future camera releases. This way of thinking is trickling down to various Canon subsidiaries around the globe to prepare for the changes coming.

As we mentioned yesterday, there’s likely going to be an accelerated product development cycle over the next 18-24 months, and video will be central to it.

After last week’s announcement of the EF 70-200mm f/4L IS II and EF 70-200mm f/2.8L IS III, most everyone around these parts want to know what’s next from Canon. While the roadmap is still a bit unknown for us, we do have some suggestions about what’s on the near horizon from Canon.

Camera Bodies:

• Prosumer mirrorless camera announced ahead of Photokina
• One DSLR at Photokina

Lenses:

• Two “professional” lenses ahead of Photokina
• EF-M 32mm f/1.4 ahead of Photokina
• New “kit” lens ahead of Photokina

Cinema:

• One more Cinema EOS body in 2018, some signs point to an EOS C300 Mark III.
• New style of cinema camera body

A couple of sources have said to expect an accelerated product development cycle over the next 18-24 months over the entire imaging lineup. We’ll let you guess what that means.
