A Peek Inside the R5 Mark II

[Richard CN]

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

It'll be interesting when we get a similar image from the R1. We might learn stuff in the comparison.

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.

Off Topic Repost:

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.

Will Uncle Rog do a teardown? I would wait with any preorder until it was in the hands of enough people to see if it melts without the fan-grip ...

I don't think he does that anymore - but Kolari will.

His teardowns belonged to my favorite websites. I visited LensRentals daily in the hope of a new victim.

On Roger's teardown of the R5, he has a good photo of the USB-C and HDMI ports. He writes, "Also, note that both the HDMI and digital out ports are part of the main PCB, so secure your cables; tugging these ports loose will be an expensive main PCB replacement."

I wonder if Canon has been able to make the mainboard of the R5II less vulnerable to stress from the ports.

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

Aaron, Brandon and Roger - those were glorious days, when the holy trinity of Photo-Tech gave as a true understanding what was going on inside cameras and lenses.

Is there anywhere already some data regarding real world DR vs. Mark I? There are so many videos from people actually already holding on to the Mark II that I am surprised there is no DR comparison anywhere yet. Or did I miss one?

no one that i've seen has done a 1:1 comparison quite yet.

The Dan Watson video had a brief look at it, but those were preproduction units, Adobe doesn't fully support the CR3s yet, etc. The results he saw from his short time with the camera, it seemed to have less noise compared to the original R5.

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.

Ok, fair enough. For the Mark I, the Adobe RAW support took also felt ages. Thanks for your both responses. My vendor said I am part of batch 1 on Aug 20th. Let's see.

Same with noise comparisons.
By the way, am I the only one to find the TDP noise comparisons (between 2 different sensors!) absolutely useless?

No, you are not.
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.

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.

The metal on the RHS of the board just looks like a standard cage for an SD or CFe card to me. The IC in the middle is pushing some serious heat, which is why there's a metal caing.

Looking at the mechanical shutter I noticed that the R7 with 15 fps burst beats the R1 with 12 fps "only". This shows that the mechanical shutter isn't a premium feature anymore, since the electronic shutter specs took over. Otherwise I am pretty sure that Canon would have limited the R7 to keep it below the R1 (a smaller mechanical shutter for an APS sensor can easier be made faster than bigger one with higher mass inertia, of course). So this shows how the photo world has changed in the recent years. About 5-10 years ago, I would have made professionals turn pale with the sound of the R7's shutter Now it is a question of a few years left, and then the mechanical shutter will end up in camera museums. And kids will no more understand why the photo app on their smartphones makes that strange noise.

In fact, since mechanical quality is important for wildlife shooters like me, I checked their blogs first before I made a purchase decision

The R6 II has 12 FPS mechanical and 40 FPS electronic just like the R1.
Canon is not crippling anything but it makes the R1 look underwhelming to people who only look at headline specs.
