    Happy reading!

    3. Thank you! Note that when I downloaded the manual from your site, the photos and diagrams were very pixelated. I downloaded directly from Canon and the photos and diagrams looked fine.
    5. The only camera Canon released this year was the R3. No other mirrorless, DSLR, or even 1" compact camera.
      The first year I remember with only a single new camera.
      With the supply chain issues I am not surprised. I hope that 2022 sees more releases of cameras and lenses.

      As I'm sure you've noticed, there's a pandemic that has affected economies and productivity. But that aside, your post is completely irrelevant to the thread.
    7. I have a dumb question that I need to ask:

      Why on the R3 is the buffer depth the same regardless if one writes to the SD Card or CF Express cards at 30 fps with the electronic shutter? For the R5 at 12 fps mechanical shutter there was a significant difference between the two.

      I should have posted a note that the viewer compresses the PDF for server purposes. Sorry about that.
    9. Canon's Compatible Accessories information says the USB Power Adapter PD-E1 "Can only be used to charge battery packs. Cannot power the camera." But I'm pretty sure Gordon Laing's initial review said he was able to do a 6 hour video using a MacBook Pro USB charger.

      Also, the official list of compatible Flash Units is shorter than I expected.
      Edit: But the R3 Manual itself does say EL/EX series Speedlites can be used.
    10. I see Jared Polin got a production unit from Canon a few days ago and now the manual has been published. I wonder if there is any chance of the R3 starting to ship before 26th November, which in US is Black Friday so seems a strange date to start shipping on.

      The list is only current flashes. Older/discontinued flashes are also compatible, as long as they’re EX (I don’t think the really old EZ flashes work on any digital models).

      Thanks for your sarcastic answer. You must feel very clever.

      The camera buffer is fixed and is separate from the storage medium being written. Its depth does not change but the ability to clear it does depending on how fast the offloading is to the storage medium. The buffer will fill up faster with slow storage medium (SD) and clear faster with faster storage medium (CFX), and thus will appear to have a bigger "depth" with fast storage mediums.

      It's probably a typo.
    16. It appears that the R3 only supports V60 SD cards, but not V90, and doesn't allow movies with SD cards at the highest data rates. That needs to be fixed! The Canon C70 uses SD cards and supports V90.

      Are you referring to the chart on page 1021? I don't think that is saying V90 cards aren't supported, rather it says for those 4K options you need AT LEAST V60.

      Your reply was my understanding as well. I do hope that it is a typo. Will hopefully find out in a few more weeks.

      You're right but it also says that high data rate video cannot be used with SD cards. The C70 not only supports V90 cards, it requires them at high data rates. The R3 may support V90 cards but their speed advantage is apparently lost. That's what upsets me.
