Indeed it does look good, and I had mulled the idea he used of a hoodman to use it as an effective MILC in Live View, I know it looks silly etc but I am having real issues converting to EVF's full time for pro work, I still find the lag distracting, the brightness odd, and looking through one for hours gives me motion sickness.

The problem with a Hoodman is that you lose access to the touchscreen, which is one of the main advantages to live view.

After seeing this I'm debating how I'm going to keep my composure if the R5 doesn't AF this well! :unsure: And then there is the, will there soon be an R1 that will be the true mirrorless of the 1Dx3, a little bigger and all the bells and whistles. And what if it (the R5) doesn't have a CFe slot?

I love how the camera momentarily locks onto the basketball a couple of times. I wonder if it's seeing a face in there or if the deep learning neural net has learned to recognize balls as pertinent objects in their own category.

My guess would be that it recognized the ball as a head with a helmet. Face AF detection should be really reliable, but the Head detection uses a Neural Network and is as good as the training data. Maybe it will see improvements over time once Canon gets more Input, like we saw with the EOS R.

Why would Canon spend so much time and effort to get the LiveView Performance of a 1D X series body as great as possible? In previous versions, there straight up was no servo AF in LiveView, so clearly they don't think the target demographic craves good LiveView AF.

I believe the 1DX III gave them the budget to lay down the fundament for future mirrorless bodies. The DIGIC X plays a great part in the AF, for instance it handles the head detection and has dedicated circuits for dealing with DPAF. It would be a shame if they didn't tickle that thing down to the upcoming models.

In case of R5, I suspect we will see mix of both SD and CFe slots rather than both CFe slots(if its prices in same range as 5D then certainly it wont 2 CFe). From the video its really interesting to see buffer clearing near instantly and best part of it being a Canon camera no lockouts during clearing process.

As it is a sports camera, it can as well be trained to recognise the ball as a ball, especially near the basket.

It could be mostly reusing the same neural net that makes the OVF AF performance as great as possible.

I didn't read anything about recognizing objects like balls in the white paper though. That's why I'm not certain tracking the ball here is really a feature or a bug - but depending on who you ask, they might just be the same ;)

The problem with a Hoodman is that you lose access to the touchscreen, which is one of the main advantages to live view.
If you are using an EVF the only advantage to the rear screen being touch is if you can drag focus, the 1DX III doesn't need that capability on screen, and it would ba a stretch with a thumb anyway, because it has the new scrollable AF button.

I'm not saying a hoodman is an elegant solution, more a way to wean me into EVF's, or at least better come to terms with when their use can be advantageous.

:D! A lot of theatrics (and I don't like this - as well as some other and more important things...). Anyway, there is no problem - I just learned not to click on the link:LOL:...
The point of my thread was the access to the first RAW files I know of.

The biggest difference I would expect between an R1 and R5 would be resolution.

No, it will 'mistake' a ball for a 'head' shaped object, don't forget we know it was taught to look for heads with helmets on, I don't see how you could differentiate between a helmeted head sitting in an open cockpit and a basketball.

I know some people who might as well have a basketball for a head (empty space full of air), so maybe the camera is that smart.
