A poster on dpreview (thank you) posted the main board and shutter assembly for the R5 Mark II.
It appears to be as if there is a huge DIGIC and another large chip assembly right beside it. I'm going to assume that the bigger mass in the middle is the DIGIC accelerator. It also appears as if the accelerator is stacked – quite possibly with memory on top.
It's a very tidy-looking board, and I'm certainly noticing there is a lot of metal surrounding the CFe card assembly. Presumably to shunt away the extreme amount of heat from the compact flash express card from impacting performance by messing up the camera thermals. Also when you imagine where this board sits in the camera, the two main chips seem to be directly in the path of the airflow up from the bottom.
There was a time we used to get a PDF white paper that would detail what each major part was, those were the days. I'll be waiting for Kolari to publish a tear-down when they get one to convert into infrared.
Next up we have the shutter assembly, but there is not much to see here, as the impressive mechanical engineering went out the window with the DSLRs.
Gone are the days when the shutter assembly took up a significant amount of space inside of the camera, leaving much more room for the other cool “guts” inside the camera body.
Even though it seems demand is high, it's a good time to remind everyone to get on the preorder list as it may take a while for Canon to catch up to demand on the Canon EOS R5 Mark II and the EOS R1.
If you compare that image to an R5 I motherboard, the CFexpress bits are just as large, but the compute stuff takes up less space. That older one also had a "bridge" attached across the motherboard that covered the CPU, which seemed really weird from a thermals perspective. We can see from the image you show here that there aren't any screw holes where the bridge would attach on the Mark II version.
You know I'm a bit over-eager to get my r5ii when I'm counting screw holes on images from the web.
From Canon's Q2 quarterly financial results, released today:
Camera "sales increased more than 50% compared to the first quarter and 9％ compared to the same period last year."
Bad news for the "Canon is doomed" crowd. 🙂
I don't think he does that anymore - but Kolari will.
I wonder if Canon has been able to make the mainboard of the R5II less vulnerable to stress from the ports.
Here's a link to R5 teardown: https://www.lensrentals.com/blog/2020/09/taking-apart-the-canon-r5-mirrorless-camera/
Yes I didn't think of that. it appears as if the HDMI and USB ports are on the underside of the PCB, you can see where the large space is on the PCB, with vias that anchor the larger full size HDMI port
no one that i've seen has done a 1:1 comparison quite yet.
Reviewers that are interested in things like that almost all say "we need more time with actual production units and support in our RAW converter of choice", so it will be a while.
By the way, am I the only one to find the TDP noise comparisons (between 2 different sensors!) absolutely useless?
They compare different cameras with different lenses and ignore moiré completely.
Sony lenses are "sharper" because they have a camera with 60 MP and no AA filter.
Canon is not crippling anything but it makes the R1 look underwhelming to people who only look at headline specs.
