Patent: Some very strange full frame lenses

Patent: Some very strange full frame lenses

By Canon Rumors | August 13, 2020 | Canon Patents

Canon News uncovered a patent showing some very strange optical formulas, they’re strange because of the back focus distance. The optical formulas in this patent have back focus distances of 0mm to 2mm.

The EF mount has a back focus distance of around 44mm, while the RF mount is much closer at 18mm.

I have a hard time believing Canon is going to get into the fixed-lens full-frame camera segment, but hey… I’d love that. :)

Canon to introduce two 8K Cinema EOS cameras in 2021 [CR2]

Canon to introduce two 8K Cinema EOS cameras in 2021 [CR2]

By Canon Rumors | August 13, 2020 | Canon Cinema EOS Rumors

Canon first teased an 8K Cinema EOS camera back in 2015 at the Canon EXPO, we’ve also seen some other sightings at various tradeshows over the years. Now that we have 8K capability in the Canon EOS R5, the next step for Canon will be to introduce a Cinema EOS camera with 8K capture.

I have been told that Canon will introduce not one, but two 8K Cinema EOS cameras in 2021. One of the cameras will be a flagship camera with “A camera” aspirations, likely in the form factor of the Canon Cinema EOS C700.

The second one I have been told will be a more modular camera in the same vein as the Cinema EOS C300 Mark III and Cinema EOS C500 Mark II. Where it exactly fits into the Cinema EOS ecosystem is unknown at this time.

I don’t expect an announcement until around the NAB 2021 timeframe, which usually occurs in April.

By Canon Rumors | August 11, 2020 | Canon Lens Rumors

The Canon RF 70-200mm f/4L IS USM has appeared for Russian certification (SKU 4318C005A), which means we should get an official announcement soon. I expect to see the RF 50mm f/1.8 IS STM to be announced alongside it.

While we don’t have an exact announcement date, we may see them announced in a few weeks alongside the new RF mount Cinema cameras and other new gear.

Canon EOS R5 firmware update coming soon, RAW light to be added? [CR2]

Canon EOS R5 firmware update coming soon, RAW light to be added? [CR2]

By Canon Rumors | August 11, 2020 | Canon EOS R

I don’t think it comes as a surprise that Canon will be releasing firmware updates for the Canon EOS R5. I have been told that we will see an update “soon”, no date was given. As with most firmware updates, it’ll be released when it’s done.

The source claims the following will be added to the Canon EOS R5, but cautions it may not come all at once in a single firmware update.

  • Addition of Cinema RAW light option to 8K recording
  • Addition of CLog 3
  • Increased record time limits (but don’t expect a huge boost)
  • Various bug fixes

These additions may not be all that is coming, but the source claims these features are what’s coming first.

Teardown: The Canon EOS R5 gets an autopsy

Teardown: The Canon EOS R5 gets an autopsy

By Canon Rumors | August 10, 2020 | Canon EOS R

Here we have our first teardown of the Canon EOS R5, and it will give you some idea in how Canon has chosen to control heat. There are a few design choices that I find interesting.

  1. The thermal pads on the CPU don’t cover the full CPU
  2. Aluminum was used instead of copper, though there is added cost and complexity of working with copper.
  3. There is definitely no venting for heat to escape
  4. Is there an issue with the CFExpress slot being so close to the processor?

As pointed out by EOSHD,  why does not of this matter when recording externally? I and others think it’s probably some kind of software limit.

Canon EOS R5 records 4 hours of 4KHQ 30p to an external recorder, with a couple of simple tweaks

By Canon Rumors | August 6, 2020 | Canon EOS R

Wayne from No Life Digital has posted a video to his YouTube channel showing how he got the Canon EOS R5 to record 4 hours of 4KHQ 30p video to an Atomos Ninja V before the camera overheated.

Simply by removing the memory cards from the camera while recording externally lead to a big boost in recording time. This seems like a pretty surprising outcome for something so simple. Is there some kind of software limitation in the camera?

A dummy battery was also used in this test.

Testing methodology:

The Canon R5 does not seem to overheat, externally, if you don’t have any cards in the camera. In this video I show (with as much proof as I can), how I’m able to record up to 4 hours in 4KHQ 30fps, 10-bit CLOG, with IBIS and DPAF all on, with no issues like the blackout or screen off issue myself and Gerald were having.

The setup here is as follows – HDMI out of Canon R5, into Atomos, out of Atomos, into ATEM, out of ATEM, into OBS on the PC. This is no different than Geralds live streaming setup, and showcasing the times you can expect as if you were recording on the Atomos. This was to record for this long period of time, without the MASSIVE Atomos file, and still show the camera was in fact running for the entire time.
