It sort of sucks for people who made a big investment into C-Fast cards but in the end it was the correct move by Canon to move to DUAL "Hallelujah" CFExpress cards which seems to be the most future proof, high speed format going forward. This camera should easily have an unlimited buffer even shooting RAW to both cards (like D5/D500) with it still being in the low 20MP range (speculation on my part based on not touting a MP jump).
EDIT: Actually, now that I think about it, I may have been shooting backup RAWs to the CF slot which would explain my buffer limitations as IR said 57 shots to the CF card in full RAW 14FPS. Maybe, Canon is touting that 5x increase when shooting to both cards RAW+Jpeg or something?? That would make sense as they are now dual CFE and should easily increase from the 42 RAW+Jpeg when shooting to both slots in the 1DXII.
Having the same slots is a huge feature IMHO, not since the 1DX (the one and only to ever do this from Canon) have we seen that and now we see it with some of the fastest cards around.

Could have sworn I saw something about 525 AF points covering roughly 90% of the sensor. Though with the EOS R claiming to have 5,000+ AF points, I don't know what to make of things.
To me this announcement is underwhelming unless Canon can reach that 16fps with at least 28-30megapixels. Otherwise it's not really an upgrade to me when they aren't even caught up with Sony. Hopefully it will have that touchscreen ability we've seen with other new Canon cameras as well, and it will need to be priced more competitively.
I think bigger news is actually the additional price drop on the EOS R. I think this is going to signal a more professional mirrorless pro body like An EOS Rx or 5D5 being announced very, very soon with shipping before Christmas.
Yeah those are the on-sensor PDAF specs, we mean the actual physical AF sensor used for OVF operation. Rumors said still 61 points, but Canon did not disclose that which is interesting, why not reveal it unless they have a surprise.

I did hit the buffer on 1DXII a few times shooting a very long SEO flight sequence (just ask Pius ). I think it was in the 60 shot range?

The IR test is silly then, black frames gives much smaller raw files with (lossless) compression than files with content.
I was thinking since they use dual CFExpress now, the writing to the cards would also be faster. As you say, the buffer may be needed when writing to both cards.
Just trying to find hints that the file size will increase
You have a good point that specifications not given are likely to remain unchanged though.

A surprise? Or nothing to report...ie it didn't change? I'm betting on the latter but see my earlier reply in why that doesn't really phase me.

Sorry, I edited my post as you were replying....I think you are correct and it was unlimited when not using the CF slot. I'm not sure if IR used black frames but I know that TheDigitalPicture did when they found unlimited. I can't recall if I ever tested it myself.

That is the AF sensor. And as PixelPerfect pointed out, most likely the iTR sensor that was only 0.36MP before so will jump to 9-10MPs. I don't believe the actual AF sensor has a specified resolution. That could mean a big improvement in OVF face recognition and priority of moving subjects like Nikon has in their AF algorithms in D500, D850, D5. All good news. But the actual sensor resolution will likely be unchanged or at most an extra 2MPs...not mentioning it in this press release doesn't bode well for a big jump to 28MP+ as the rumors were saying. But we now know just about everything in the recent rumors were incorrect meaning the rumors were made up...no IBIS, no new battery, etc......Show more →
Yeah, all the talk of IBIS, 6K video, new battery, are bogus, so worried about the sensor res. 22MP would be really weak, I mean at least make it 24MP. If dual digic 6 can handle 20MP @ 14fps, dual digic 8's let alone 9's should handle even 40MP @ 16fps based on the historical rate of throughput improvement of digic, but with all the pro whining about file size, hard to see Canon going beyond 24MP. Still there are some features which a better than I thought and it looks to be better update than 1DXII even without knowing all the specs. Can't wait to see D6 specs.
A surprise? Or nothing to report...ie it didn't change? I'm betting on the latter but see my earlier reply in why that doesn't really phase me.
But normally they would say larger coverage, AF down to -4EV, etc they didn't hide that when 1DXII was announced did they?
It's not a big deal so much of the number of points but of course how they perform. Same basic system is great if they have really improved the performance and if this deep learning addition isn't a gimmick. Still I was hoping they could offer greater coverage in OVF use with even just another vertical row left and right and horizontal row top and bottom, maybe another 20 points or so. Maybe not physically possible for this sensor in it's location off sensor or it might have meant smaller sensors that would be less sensitive. Still you'd think the tech would have progressed from the 1DX days.
Anyway if it fixes the few weaknesses Canon has compared to Nikon and Sony I don't care how they do it.

Whys is the buffer depth increased 5x when the mk II already had unlimited raw buffer at 14 fps 20 MP?
I was thinking the same thing. However the Canon spec on the 1DXII does not say unlimited, if if testing showed it basically was with the right card. Now it would be effectively officially unlimited without them legally saying unlimited as someone will always be out there claiming not to able to get an infinite number of shots and then sue them.

And it will be when shooting to both cards full RAW+Jpeg or now RAW+HEIC
Who in the world is going to shoot action via LiveView while looking at the back of the camera?!?
If indeed LiveView AF performance is on pair with OVF, 1DXIII will be a great preview on what’s coming in the mirrorless version of 1D. Unfortunately, we won’t see it until 2021...
Lack of announcement on the sensor resolution means a minor bump I think.
I hope that there will be an option to assign more functions to the new AF button. Also, will the touch work with gloves on?
Hopefully we will get more information in upcoming days from PhotoPlus Expo in NYC.

Agreed, the only reason I would use it is if it had a flip screen and I could shoot my water level shots like I do with my MILCs. But I wouldn't be doing fast action or BIF with it in LV.

Three words.
Red Dot Sight
I've been hearing about several people using a Dot sight while in LV for fast action shooting on their DSLRs with great success.
I must admit this sounds cumbersome and awkward to me, but I'm going to yank one of my Red dots off one of my rifles and give it a try. From what I've read, the biggest issue is keeping it calibrated while in use. It sounds like the hot shoe doesn't provide a tight enough tolerance to hold the mount secure enough and just the slightest bump can throw it out even with the set screws holding it securely.
Should be an "interesting" experiment to play around with when I have time. It'll most likely end in pure frustration though.
For what it's worth, imaging resource tested the buffer of the 1DX Mk II and with raw+jpg it slowed down after 73 frames, after which it continued at 8 fps. And this is with CFast. If someone needed in-camera backups, it is possible that the buffer limit is reached due to limitations of the secondary (CF) card. These limitations (which are not too serious...) may be alleviated by the use of CFexpress cards.
I sometimes shoot action using LV when I need to rise the camera above my head (such as in a crowd) or at a low level close to the ground.
I wouldn't be surprised that the III will use AF like in the Sony 99II which uses an off site module with 79 points and PDAF on sensor to effectively gain hundreds of points of AF & where they over lap become cross points. (run on sentence, sorry)

I don't think 16 fps will be useful, the mirror blackout time in DSLR's is a given, typically 45-50 msec on the pro models. At 16 fps the total blackout time is 16 x 50 msec = 800 msec in each second of burst. which means when tracking a subject you and the camera are effectively blind almost 80% of the time! It will just lead to more missed shots or redundant frames. When I had a 1DXII I actually dialed it back to 12 fps...seemed to be enough to capture the "peak of action" moment
the only way to go to those high frame rates and still be useful is with the mirror up in LV or in mirror-less cameras... then it becomes a challenge to maintain true 120fps live feed during burst.
Just when I thought I could believe you, Pixel Perfect, and the other guys who claimed 16fps wasn't possible see below. And I'm happy to hear B&H confirm my first post that started this whole thread might be coming a reality. I guess 16fps is possible, but now we wait to see what the MP count is...this camera is looking to be a screamer.
). I think it was in the 60 shot range?
