Here is the Canon EOS R announcement live
- Thread starter Canon Rumors Guy
- Start date
They needed to release a super wide lens RF lens with that 4K 1.6 crop.
You can't vlog with a 24mm lens, or a 3lb lens (28-70). The 24-105 also has a min. focusing distance of 17.71 inches...
Yes, you can adapt to an ef-s lens (no 60P) 10-18 which is much lower quality or use an other existing wider lens that will introduce noise when focusing. Unfortunately, this likely won't work for me.

i presume it draws power to keep shutter open, for me that would be the logical thing to do.

Erm... how can the same sensor have more phase AF pixels when it uses DPAF?
It’s the same sensor with a different software implementation for selectable locations.

Actually, Canon missed a marketing coup by not saying that the EOS R has 26,492,928 DP AF points, which, for purposes of usability, was simplified to 5655 selectable AF points.

Exactly. Canon missed highlighting that back with the 70D & 7D2. Imagine the press release with "16 Million AF points in Live View & EOS Movie shooting".

There could be practical limitations in how these pixels are grouped together for more reliable (less noisy) phase detection.

Agreed. I assume software establishes line pairs (albeit with a single column of pixels) in specific locations rather than having some amorphous blob.
It’s likely that some locations work better than others, and additionally having discrete predetermined locations is computationally lighter than some dynamic implementation.

The area of the sensor that can be used for AF is roughly 80%x80% in the 5D4 generation DPAF. Whether the rest of the sensor physically has "normal pixels" or if it's only a software limitation to prevent potentially poor AF behavior near the edges I don't know, but the end result is the same. In the R, like in the M50, the area that is usable has increased to 88%x100%. So it is fair to say that there are more AF pixels (effectively if not otherwise).

Has anyone noticed if DPRAW files are exactly double the file size of non DPRAW files? I guess you'd have to take the exact same photo twice to know for sure since RAW file sizes do fluctuate.
I can't imagine that there's some periphery around the edge of the 5D4 sensor that physically does not have dual pixels compared to the middle of the sensor. Seems like it would be much harder to manufacture a sensor like this compared to one that just has uniform pixels throughout.
Also, in relation to that bokeh shift feature on the 5D4, I don't think you could do that without some weird artifacts around the edges of the photo if the sensor did not have dual pixels all the way through.
Not having 100% focus coverage is probably just a software and processor thing. Besides, if the subject you're focusing on is really that far to the edge of the frame, maybe you should just consider recomposing your photo.

Yeah, after I posted it occurred to me too that DPRAW certainly implies that the whole sensor is dual pixel.

The claim is fastest to lock, not fastest throughput. With fps, the bottleneck can be the mirror, shutter, AF system, or CPU/buffer to move the data. Yes, the mirror is removed, but the other bottlenecks may remain.
The (sort of) SLR equivalent of this camera, the 5D4, has 7 fps as an SLR and only 4.3 fps (I believe) with Liveview -- which is how the EOS R also focuses. So in that light, 5 fps isn't terrible. My guess is that DPAF + tracking (i.e. Servo) is too large a computational lift for high framerates in this class of camera, and that will improve over time.

May be when the R series gets to the level of 1D, it will be larger, thus able to have 3 processors with one dedicated for AF and increase frame rate.
Beings the Olympic games are in Tokyo 2020 it may appear before that, so 18 months time.

The 1DX2 already can shoot 16 fps in Liveview with AF working ...but not under Servo AF. I've been looking around for a published actual top speed with Liveview burst shooting doing the tracking work and I can't find it at either TDP or Canon proper. (Anyone know?)
Total bushleague thumbnail calculation based on EOS R specs:
- EOS R
- 30 MP x 8 fps = 240 MP/sec possible in Liveview + AF (but no Servo AF)
- 30 x 5 = 150 possible in Liveview with Servo AF
- ---> Servo AF under Liveview saps 37.5% of the throughput.
- 1DX2
- 16 MP x 20 fps = 320 MP/sec possible in Liveview + AF (but no Servo AF)
- 37.5% less throughput would be 200 MP / sec
- 200 MP/sec by 16 MP = 12.5 fps

You know, for all of the ways that this camera seems a little lackluster... No dual card slots, not the fastest fps, at least they're giving us essentially the best full frame sensor they've got. Yes, it would've been wonderful for it to be an all-new sensor with even better specs than anything else they've released.
But, at this price point, they could have just thrown the 6D II sensor in there and called it a day. And then I would be really conflicted, because that would set up the choice between having better image quality in the 5D4, or the mirrorless technology in the EOS R.
As far as ultimate image quality goes, this camera doesn't seem like it will force us to compromise compared to a 5D4, and that's really nice.
