Canon EOS 90D Specification List [CR1]
- Thread starter Canon Rumors Guy
- Start date
I said in an earlier post, it may be that they are stating Effective Pixels rather than total pixels.
Interesting...
Firstly, maybe the registered 32.5mp sensor is listed as 31.2mp due to the IBIS?
I’d be incredibly surprised to see an EF mirrorless! If this is true, then Canon should not have bothered with the RF mount (yet) and just used their EF mount for their mirrorless range. Sure, the RF mount enables incredible lenses but Canons EF lenses are already pretty incredible so..

A perceived advantage could be using EF(-s) lenses without an adapter. I have nothing put praise for the RF-EF adapters, but some folks just can't stand the idea.
Canon may have had this camera in process as a test bed for new technology prior to completion of the R interface and components that could be used for full system testing. The camera may have been stuffed with all the latests tech on an EF platform - sensor, communications channels, digit processors, IBIS, new AF as a testbed, EVF with fast refresh. It could be the tech demonstrator to pull the flock back together. Do I hope for that, Yes. Do I expect a 5d type miracle, NO. As someone else said, it is humorous that we wonder if there is truth in this rumors because of the crazy things Canon has done n the past. Let's hope they are Bats*** crazy and release a killer last EF mount camera (plus the 1dxIII. Who knows?
In one of the recent IBIS patents, Canon has what seems to be an EF-mount mirrorless camera with EVF and IBIS. It's just a patent, but it's obvious that Canon at least experiments with EF mirrorless things. (It also seems to have a mirror inside the EVF, so technically it's not mirrorless.
)Hmm, 10fps, just like the M50...
I'm thinking that maybe we won't see a 90D, but a M5 Mark II replacing both the 80D and the M5 instead

I would think higher DR and DPAF both slows readout,more data needed get out sensor? so if you get both frame rate would be super slow?
hey maybe its sony sensor with canon patents so no dpaf and no cropping =8k .
werent here earlier some fake rumours about backlighted 32mpix 7Diii

There is imo very low chance we will see EF mirrorless, unless we would have to consider Canon being just insane. Why would they come up with a RF mount then, risking by making it even an M mount incompatible? I still somehow can't accept the fact, that there is no upgrade path for an M mount cameras. What is imo more likely, is the chance of an APS-C with a RF mount.

Canon made a mistake in my opinion in 2012 when they designed the M mount and not accounted for a future FF mount.
I think they thought that mirrorless will always remain a cheap and consumer line and will never go FF.
The M would be the perfect system to complement the RF system if would be compatible with RF lenses.
It does require more data but I don’t believe that affects DR as much. Dynamic Range has more to do with the minimum amount of photons needed to trigger the pixels while keeping the noise to a minimum.in fact, Canon has been working on quad pixel Autofocus technology for a while that could theoretically be saved separately so that software Pixel shifts that into a much bigger image programmatically.
The biggest impediment to doing this is simply that Canons sensor chip fabs are way, way, way behind Sony’s in the ‘die’ size. This makes each sweep of readouts from every pixel take way longer than Sony’s sensors do. That’s why the quality of the picture is nearly the same but the speed isnt. The silicon under the pixels (which by physics are nearing their limits) can be much smaller than canons current tech, which means faster and less power. As you get smaller the cost of manufacturing goes up almost exponentially. Sony sells millions of chips to cell phone manufacturers, Canon doesn’t. If they have invested in a new fab, expect to see canon made chips in other brands In the future. If they haven’t, they might be outsourcing the fabrication of the sensors to a third party. They are a major player in lithoscope technology which is a component of a fab so their costs would be less expensive than other companies, but that is just one step of many in the expense of creating a new fab.
Canon uses a 1:1 pixel readout for 4k. They are somehow unable to sample a 4k image out of the full sensor area. maybe a heat or processor or sensor redout speed related problem. So they "fix" this by just taking the middle area for 4k with 3840x2160 pixels. this results in an insane crop mode on higher resolution bodies.
In the industry, nobody wants this, its just bullshit. Super 35 (about 1,5, so about the same as canon APS-C) is a nice format for filmmakers (you can shoot wide open with it with super fast primes, without a toooo shallow depth of field. But 1,9 crop like on the 5d iv is just completely unusable (paired with the completely insane rolling shutter, it rendered the 5d iv VERY unpopular amonst filmmakers)
They are related though, a smaller process node allows for more electronics to be implemented on the sensor than a larger process node which can help with readout speed.
