I'm still a little lairy about how easy it will be to move around the AF point field quickly though. The spec sheet says:
but they appear to be pretty small controls for man hands and sausage fingers to contend with..!

Here are the first images and specifications of the Canon EOS R and the new RF mount lenses
- Thread starter Canon Rumors
- Start date

That would be one thing that would make me consider ditching Canon. I love my Canon glass, but I love my Sigma glass enough I wouldn’t want to be tethered to a system cut off from that lens innovation.

Wonder if Sigma lenses become usable on Canon with DPAF or if it’s the same as today with DSLR and PhaseAF via VF.

I laugh at all the old people here still talking about resolution in terms of how big a print you can make. Go back to your darkroom, grandpa!
I do primarily images for online. And with 5K+ screens (14 megapixel) becoming the norm images for screen display a 24 megapixel sensor doesn't end up giving you a great deal of crop flexibility. 40-50 megapixel sensors give much better options for cropping and/or downsampling images to be displayed at their best on a retina-style screen.
People tend to still make "real money" by sellng wall art.....you know, the stuff good enough to occupy a permanent place on the walls of your living abode?
Web shooting is transitory, but quality art for walls, lasts...and often brings in high $$'s.
Now...get off my lawn!!

The most layers in a printed circuit board is 129, and it was created and released by Denso Corporation (Japan) in Chita, Aichi, Japan, on 13 June 2012. So, yes, somebody can.

The “you really can’t” was a question, i.e. he was asking why 70 were needed, not if it’s possible to route with that many layers.
If you’re constrained for space and have a bunch of traces which need isolation, adding ground planes is an easy solution. Most boards I see these days have 20 layers or fewer.

After reading trough 30 pages.. some thoughts:
Market position
I think it's obvious that the R line is far away from the M line and more close to Canons FF DSLRs. And R lenses obviously more in line with EF than EF-M. If the body will really only be named "R" without number, i guess we will see more segmentation later. And like the M at the time it's a first shot and they will listen to feedback before developing a different form factor.
Lenses
Complete opposit of EF-M and a boom like 28-70/2. Would the same be (economically) possible in EF? AFAIK a lens must use a retrofocus/reverse tele for FLs shorter than the registration distance. On EF, 28 is within that range, on R it's not. All in all an impressive lineup. Maybe we will see cheaper lenses later, like variable aperture zooms and 2,8 pancakes or so.
Mount
I was a bit surprised by that move but if it enables lenses like the 2,0 zoom it seems worth the hassle. Also, we have to wait and see what canon has officially to say about the benefits of the new mount. A shorter mount is only usefull on short focal lengths, so i guess we won't see any big whites in R anytime soon. On the other hand, Canon could someday offer a EF to R conversion simply by changing the part of the lens body that the mount sits on or by bolting on a fixed, sealed and calibrated extention tube.

Sigma EF lenses would continue to be useable via the EF adaptors. But it may be unlikely that Sigma would be allowed to produce RF lenses. At least not for a few years.

I'm kinda disappointed on the options. Those sound.... non-creative. If they add strange slide&touch&push -bar, it should do some cool things. Zoom-control would be interesting feature, assuming power-zoom lenses.
Or maybe EVF zoom control to help confirm focus. There's no reason why you wouldn't be able to zoom on EVF, snap to 10x and back with a swipe.

It isn’t very often, but sometimes I find myself with the 5D4 needing to use a different light source at roughly the same distance in order to focus for a shot I’m taking. This is typically outdoors in the evening, shooting a creature. This works maybe one out of five times. So I will follow up by manually focusing, racking the focus as slightly as I can from one direction, through the proper focus, and onward a few extra ticks. This might give me eight or 10 shots, and later I can pick the one that is the best focus. That works about half or 2/3 of the time.
For still subjects, these tactics work for the most part. But I was trying to do things like photograph bats when they come out in the evening, and of course that just wasn’t working.
I very much appreciate -6ev.

I think that Canon has shown some innovation with this new camera. Although it does not sport a native EF mount, the EF lens adapters are innovative, like with the drop in filter mount and the control ring mount. Even Nikon could not think of that. Then there are two small, but important things that both Nikon and Canon did get right over Sony. The inclusion of a top LCD and making the camera with a better and longer grip. That's what you get from the two top camera companies, cameras, designed with a photographers needs in mind.

This is one of the reasons I would not touch a Sigma or a Tamron lens that is not “dock compatible”.... with those ones, you can easily get firmware updates.....

This is now fantastically off topic, but it’s interesting so I’m going to keep at it.
That is also my industry, in particular military comms (C4ISR). The customer is often very sensitive to layer count, because there is a relationship to yield. It’s obviously not the end all be all; a 20 layer board with micro vias and sequential laminations is probably riskier than an 80 layer simple board, but still, they don’t like it.

If this cam is the prosumer camera, which way or ways will the pro bodies go?
Will a DX type have like 24 MP and a high frame rate say greater than 20 and the 5 series equivalent go for high MP and lower FPS, say 8-10 and trickle down tech, or option B might we actually get a 50MP DX with a 15+ FPS.?
Option B is too good to be true, and not in canons method of operation, and lower lighting situations sporting events etc will probably still require the lower number larger pixel solution.
And of course when?

I've not worked in the PCB industry since 2003 when it seems most of the board shops I serviced moved off shore. I worked for KCA (Anaheim), Multek (Irvine), and then for an equipment and material supplier/servicer in Orange (Circuit Image Systems). Also worked for a contractor I can't mention. I think Korean Circuits of America (KCA) is barely hanging on in the U.S. I'm not sure Multek is even still around. I believe their operations in Irvine moved to Guadalajara years ago, and CIS went bankrupt in 2004, I think. The founder of CIS (Marv Bain) is now deceased.
I actually built a direct impingement copper plating prototype (my design) in 2001. You know why that's important when it comes to vias.

I don’t know any of those shops, but we still have some regional ones like Hughes Circuits, Streamline, and TTM (was VIA systems). There are actually dozens of shops, of highly variable capability
