567 PD pixels on the A7riv of 61MP in total? Not a big deal. What was more of a problem was that a sensor being constantly busy produces more heat (-> noise) compared to DSLRs.
Canon's DPAF won't come with no penalty, too. They use almost 90% of the pixels now in the 1dxiii, for example. Shouldn't read noise be higher with more diodes being used simultaneously?
DPAF has the advantage of producing no striping in backlit scenarios, something I encounter with A9/A7iii from time to time (Nikon has that, too of course). I think cross-type sensitivity can be much easier implemented with Canons DPAF, too (Sony + Nikon right now have only a linear sensitivity) and you have many more active AF points for AF, giving you the possibility to build up a depth map or use those for pattern recognition. Although being a Sony shooter, I see great potential in DPAF.

Dual pixels are read as two diodes for AF calculation exposures only. For the exposure that makes the image, the two diodes are coupled and read as one.
More importantly, a tiny bit more noise is less annoying than striping, even if that occurs only once in a while. Sony cameras does handle it better than some others, like the Fuji GFX 100 that tries to fix the striping but introduces shadow banding instead. The cure is worse than the disease, and reduced the usable DR of the most interesting medium format camera significantly.

For cross type sensitivity, wouldn’t we need quad pixel AF?
You would need an other type of orientation of many of the pixels. I like the Interview with Canon at IR, a very good source in the past for well informed interviews and there are a lot of nice talking points (flange distance, mount diameter etc.).
Due to the very high number of AF points the linear orientation is not a big problem:
"but when I asked the Canon engineers about it, they gave essentially the same answer the Nikon engineers had about the Z7: Thanks to the very high density of AF points, the chances of missing focus on a subject because it has no horizontal detail are very low. Even with a subject like window blinds, if the camera is the tiniest bit tilted relative to the subject, an edge of a slat (for instance) would cross an area covered by an AF point, letting the camera focus."
As the Z6/7 have clearly less AF PD points, they are at a disadvantage like Sony, as we all know. https://www.imaging-resource.com/news/2018/09/15/canon-eos-r-qa-with-the-canon-engineers

Agree to the striping.
One more thing, the number of AF points does not equal the number of PDAF pixels. Each AF point needs a number of PDAF pixels to work. IIRC the PDAF pixel density is about 1:5 in the newest Sony cameras, destroying about 1/25 of the pixels or 1M pixels.
Sorry all, meant to say 1:5 out of the blue pixels, not total pixels. So it will be only a quarter of what I said earlier, so typically up to 250 K pixels are PD pixels in a modern 24 MP Sony sensor.

The EOS-R5 should logically be an allround mirrorless pro body like the 5DIV is an allround pro dslr. There is not yet a reason to release a 1DX like mirrorless AF and speed monster because Canon still needs a couple of years to make the RF lenses for such a body, like a 300mm f2.8, 500mm f4, 400mm f2.8
Because the existing EF lenses adapt very well to the EOS-R, everybody seems to think that Canon will be content to develop a mirrorless top body without the neccessary EF lenses, but that is not like Canon.
Look at the EF lenses developed so far: they all fit a 5DIV like pro allround mirrorless body like a glove. Canon has most likely with intent worked on the lenses for the EOS-R5, and now they're here, it's time for the body. I don't expect super sports wildlife performance yet though, that is for what comes after, when they have the lenses ready. ...Show more → EB-1 wrote:

I've owned the a7r III since the first week and it has some good points, but a lot of annoying limitations. Canon noise is less ugly than Sony noise, so 45MP Canon can be usable for some situations. The big questions is whether it will be a bit cleaner than the old Nikon D850. Maybe by next year there will be a 30-32MP body with AF at framing speed, an updated EOS R.
In any case, I'll probably preorder the R5 to test with the EF lenses. There's too much nonsense and too many uncritical users online to get much useful info without both controlled indoor tests and field trials.
gdanmitchell wrote: markd61 wrote...Frankly, Canon is just beginning to flex it’s considerable tech prowess in the mirrorless field. The RF line of lenses has already made a statement of intent and seems to be just gathering steam.
So for the moment, I believe Canon is about to loose its first rounds of shock and awe in the mirrorless body campaign.FWIW, while I don't actually "know" what is coming from Canon, I think we all have some suspicions... and the process is one that I've written about for some time. My thinking has, for several years, been something like the following.
First, Sony made an absolutely brilliant set of moves when they introduced the mirrorless A7rII full frame camera. Sony recognized that they were very unlikely to be as successful in the DSLR space, even though they had proven that they could make competitive DSLR systems. The issue was that the base of Canon and Nikon DSLR users was so large and so invested in those systems that it wouldn't be enough to equal those brands — Sony would have to exceed them significantly in terms of features and performance and probably at the same or lower price points. That was, as Sony recognized after trying, going to be a nearly impossible task.
So Sony zigged where the others were still zagging. To this day, I think that nearly everything about the introduction of the A7rII was brilliant — even though I personally did not find the camera compelling for my own photography. What made it so smart?
1. The camera appealed to the portion of the market that is always looking for the cool, new thing since the cool, new thing was the full frame mirrorless camera.
2. They went right at "early adopter" types (who often don't fully trust their existing brand, and often think the grass is greener on the other side of the fence). These folks also tend to be a lot more forgiving of new systems that have some rough edges and limitations, since the potential of the new system appeals to them.
3. The first model offered the highest resolution sensor then available, so it naturally appealed to high-MP fans, in particular landscape photographers. This went straight at Canon, whose high-MP cameras at that point were lounging around in the 20MP range, while the new Sony had 36MP. (Nikon also had 36MP in the D800, but more on that it moment.)
4. Sony also went straight at Canon by largely foregoing the marketing of Sony-native lenses, instead offering an adapter that allowed Canon lenses to work on their camera. There were issues — some lenses didn't work well at all, and many worked less well, but the cost of trying the Sony system was greatly reduced for Canon owners who could bring their existing lenses along.
5. While the adapted lenses didn't work well enough for some uses dependent on critically accurate and fast AF, they worked fine in less challenging circumstances, and arguably as well for things like landscape as they worked on native Canon cameras... which, remember, now looked less appealing by way of their lower MP sensors.
6. All of this gave Sony quick market penetration, and as they began to build out lenses and improve the operation of their cameras they already had a strong and growing base in the market.
Someone will — if they haven't already — do a case study on this and use it to illustrate some principles about marketing and development strategies.
At that time, we heard the constant refrain of "But Canon isn't innovating! Canon is falling behind! What's wrong with Canon?!"
Well, yes, but...
Unlike Sony, until then a small player with a tiny installed base of users, Canon could not afford to move as fast or experiment on their customers. Consider for a moment: If the exact same camera that we got with the A7rII had come from Canon, the reaction would have been almost entirely different. People would have complained mightily about the AF problems. They would have rejected the need to use old lenses with adapters. They would never have tolerated the less sophisticated interface. The installed base of Canon users would have — let's be honest here — pilloried Canon if they had released the very same camera under their brand.
That is not an indictment of Canon nor Sony. It simply recognizes the different realities for bigger, established companies versus upstart players in a market.
The big company cannot bring a product with a lot of rough edges to market. They have far less ability to experiment on their users. They need to present an entire integrated system. They can't rely on telling users to buy parts from a competitor.
And Canon didn't do those things. They set about on a longer-term development process that literally took years — as they had to do — with a goal of being able to introduce a fairly mature product line-up that would, from the start, compare favorably with their existing DSLR line-up, and if possible exceed its capabilities.
It looks like we are getting very, very close to seeing the real fruits of that long term process. Arguably we begin so see some wins in the M cameras, and we are seeing some clearer evidence in the R and the RP. But even more so, we are seeing it in the lenses. Canon knows that if they are to move users to the new system that there must be lenses ready to go. Increasingly it is clear that there are and will be. Existing EF lenses appear to work essentially as well on R systems as they work on DSLRs, by means of an inexpensive adapter. But even more important, as Canon introduces new R lenses they almost always exceed the capabilities of the previous EF incarnations in some way or ways. They have a larger maximum aperture, a larger focal length range, better image quality. What I think we are seeing is a plan by Canon to make sure that when current DSLR users look at the new R system they will understand/think that a) they can bring their existing lenses along, b) the new system performs as well as or better than the older systems, and c) that a extensive line-up of native lenses is available, and d) that the new lenses also offer advances over the old lenses.
Make sense now?
"Will it live up to the hype?" I have no idea, but it looks like Canon is rolling out at pretty serious and respectable system.
BTW, this is not intended to be pro- or anti- any brand... They all are producing really fine gear these days....Show more →
Canon can afford a longer R&D period between cameras than Sony because their bred and butter are their inexpensive consumer cameras and lenses. I agree they’ve produced some very impressive RF lenses so far, but how they manage expectations for the R5 and how that camera delivers I think is a huge gamble.
For the reasons you’ve mentioned, it can’t not perform. If it’s the actual cross of the a9 and a7riii that it appears to be, I may move to Canon. But that’s a big if.

Yeah, I understand all that but Dan made at least two mentions of Sony directly going after Canon users and Dan even goes as far as saying they forego their own lens development to go after Canon glass owners....I call hogwash on that because there is no evidence of that and it is blatantly false information that they made an EF adapter.
I made at least one error and perhaps two, though I don't think they change my overall point.
1. I mentioned A7rII where I meant to refer to the 36MP A7r which had a sensor equivalent to that in the D800 and (more accurately, perhaps) the D800e.
2. I apologize if I'm mistaken about Sony producing/selling an adapter to use Canon lenses on the A7r. Was that only third-party stuff? Given the overwhelming argument that photographers could take their Canon lenses along to the A7r, the enthusiasm for doing so, and the fact that this was the only initial route to having necessary lenses at first...
After acknowledging and correcting those errors, I think my basic analysis is still correct.
Sounds like some are getting nervous and sending out warnings to Sony.
Can't say they were not warned over a year ago.
Go Tokura (Canon's Image Communication Business Operations Chief Executive)
"As you may know, Canon has a history of not always being first in the market with new technology, but we are very good at catching up, going beyond and becoming the leader."
I've long advocated that part of the advantage of mirrorless is that the space / size design changes that come from the mirrorbox being no longer necessary ... is that you now have MORE SPACE to engineer / design / work with for power generation & heat dissipation.
I've said for years that if Sony would build the mirrorless in a larger body (or whoever decides to first) will do well, because of the performance capability. Sure, you can still make it smaller than if it would have a mirrorbox ... but, that doesn't mean you have to give away all the advantage, just for the sake of making it small.
Judging from the pics, it looks like Canon is going to retain sufficient size to pack some punch. I mean there's a reason why a 1D series is larger than a 5D series ... power & heat dissipation require such. I'm glad to see that the R5 appears to have a thick body to support the engineering guts.
Combined with what looks like a good layout (joystick & assumed touch screen), a size that looks like it'll land between a traditional 5D IV, and the EOS R ... I think they may have put the mirrorbox space to good use (rather than just whittlin' down the size ... because you can).
Imo, if they have taken their time to figure out how to best use that space for power / heat dissipation (and card placement, etc.) ... well, if the time spent to crack that nut was well used. I'm seeing a "home run" for the EOS-R5.
Video @ 8K ... on spec is great, but since I'm not video oriented, the 12 FPS mechanical & 20 FPS max is going to be sweet. I mean, 20 fps @ 40MP-ish ... that's some processing power that is a quantum leap over some previous FF spec. Typically, you have to choose between fps & MP to accommodate the processing limitations (back to power & heat dissipation).
If my read on this is anywhere close, this EOS R5 (with IBIS, so now we can use more glass) is going to be rather well heralded. Will it garner the same as the original 5D for its place in history, maybe not quite that much ... but, let's just say I think it'll be one that proves itself to have been worth the wait. Which is really tough thing to say about Canon, because we all love to hate on how slow they are at getting there.
Time will tell, but the early presentation lends me to think that Canon got this one pretty darn good (at least in the direction that I've been hoping for) ... i.e. 1) use the space to increase power / heat performance capability and 2) use the space to retain good ergonomics. I sense a world-class workhorse is about to hit the track ... not just a Shetland pony that is smaller in size.
We'll soon find out ... Build it, and they will come. This one could be worth waiting for.

That was all done via 3rd parties, just as the Nikon (and other) adapters were. The only adapter Sony made was for their A-mount lenses.It wasn't that they necessarily "targeted" adaptation of Canon glass by original design / intent. Rather, they became the benefactor of Canon's glass through (3rd party) adaptation ... and that was quite a benefit that lended them a helping hand in popularity.
For instance, the ability for landscapers to use Canon's T&S glass on Sony ... something that Sony likely is not ever going to develop. Same goes with other glass, in that it "bought them time" to either build or continue to borrow. In this regard, Sony had a full lineup of glass without having to produce the entire lineup.
That's not to take away from Sony's development of their own glass ... just saying it had some serious added benefit to them, that without, well things might be a little bit different....Show more →
It sounds like Sony targeted everyone else equally since they open sourced the E mount back in 2011. They didn't have to engineer and build an adapter. Why market something that you hope will only solve a short term problem and that Sony would likely have to take on support liability for their in-house adapter if the other guys lenses don't always work as advertised on all Sony E mount Cameras. After all there's a number of 3rd party manufacturers will independently do it for you no strings attached. Sony probably realized all of this after FotodioX, or whoever was first, introduced their (reversed engineered?) adapter in 2006.
Now that Canon just surpassed the A9II with a DSLR, just imagine what we're going to see with a full MILC flagship 1R.
Based on what we're seeing on the 1DXIII, I'm hopeful the R5 picks up the same AF features which would equal the A9II at a release price of $3499.
I keep hearing the cute little buzz phrase some Sony YouTuber came up with. The "Canon cripple hammer".
Funny how that little phrase has an opposite meaning now.
1. At times any of several companies could have the most compelling photographic tool, with your assessment of "most compelling" being somewhat subjective and different depending on what/how you photograph. The "lead" among companies rotates over time.
2. In a truly objective sense, the differences are far less important that we imagine — the fact is that all of these companies are making extremely competent equipment, and the difference between the best thing and the second-best thing in some aspect of camera performance is actually not that great. In addition, the second-best thing is almost certainly better in some other area of performance.
Regarding #2, I think there's a sort of inverse proportion principle: The more strongly you regard your camera company affiliation as if it were that of fan of a sports team, the larger you imagine the differences to be when they favor your brand and the smaller you regard them to be when they favor another brand/team.

Not really. Canon doesn't have a stacked sensor (1dxiii has 1/60s read out only. I don't need mechanical shutter unless I use flash at all with the A9ii. So the Sony stays in E-shutter 95% of the time and doesn't wear out the shutter. You can use it in LV or EVF mode at full speed). Buffer never has been an issue. I never shoot at 20fps for half a minute and I don't know anybody having done that at big sports events. Nevertheless, that is a weak point of the Sony.
Regarding AF, Canon just managed to get close, maybe even if we are nice, to Sony's 3 year old technology (!) at 2000 Euros less than the Canon.
You are dreaming to think a non-flagship R5 to even surpass the 1dxiii, all that with a higher MP sensor and in a much cheaper body. How realistic is that? We don't even know what the R5 will bring to the table in detail (20fps with AF frozen or not, etc., 12fps with frozen AF, or not, nothing is clear right now).
You seem to think this (likely) 45MP camera to surpass A9ii AF, won't happen. So your comment sound like a fanboy delusional comment, sorry to say that. And that comes from someone like me, even thinking of adding an R5 (I am not brand addicted).

Don't count your chickens before they hatch. Until we see what Canon does with the R5 and whether they ever move to a R1 (and if they do how far out it is) it is premature to really compare an R5 to an A9II. By the time an R1 shows up there could be an A9III or an A9R or who knows what....one can wish for anything but until I see a full spec sheet and can read all the caveats in the user manuals I'm not going to place my bets or my $$$ onto either system.
The Cripple Hammer may still rear its ugly head with the R5 especially if the price point is $3500 (I'd bet an extra $1K onto that price). The Youtuber that made that phrase is a M43 shooter for the most part and he isn't a stills shooter, all he talks about is video. I think he occasionally uses an A6400 but that is it for his Sony use.
I wouldn't get ahead of yourself on the R5 just yet....it sounds like Canon plans to finally close the gap, but Sony will probably soon respond with another TKO uppercut.
I'm sure no matter what, it will be picked apart by critics on technical details, but I think it will be a great camera. I'm sure there will be some brand wars comparisons on tenths of a stop of dynamic range etc. etc. If you can afford one and want one, go for it! If you shoot Nikon or Sony, someone with this gear is no better off than you and vice versa in most practical situations.
Meanwhile there are still people shooting with a 5D Mark I that still do great on things such as composition and exposure and who spend time out shooting instead of bragging for self-validation or tearing other people down on forums, which unfortunately seems to be the norm for any sort of gear post or question these days, including this one, which is unfortunate.
I'm most looking forward to smaller form factor, weather sealing and potentially dual card slots. Depending on the price, it may be some time before I buy one if ever. I do want to get into the R mount, but maybe I wait for an R6 (6D equivalent) or wait for the cost of the R to come down.
