How did I miss this? Bird eye detection?

"effectively tracking the whole body, face, or eye of cats, dogs, or birds for speed and precision."

So the R5 and maybe R6 will track the eye of a bird?

If the processor is powerful enough this might be very interesting.   Or it could be a gimmick.

The 9th will be a fun day.

I wonder if birds’ eye can tracked at the distance we normally take pictures of them.

Yes, it will be an interesting day

Maybe that's going to be the biggest argument for having an 800mm F11 instead of cropping from a 100-400F5.6L2? Both give you the exact same amount of light gathering, but the former will let you throw four times as many pixels at the bird's eye, which should help with recognition and tracking.

How does F5.6 and F11 give you the same light gathering?

example,

if F5.6 gives 1/200 at iso 800 then

F11 at 1/200 would give 3200 or 4 times less light

or

if F5.6 at say iso 800 gives you 1/100 (which it often does here in the uK)

then

at F11 at iso 800 would give 1/25 which is unusable.

F5.6 to F11 is 2 stops or 4 times less light

On the plus side, AF at F11 works on these mirrorless cameras which is great but it's slower than a lens at f5.6 or F4.

I can see these consumer-grade F11 lenses been popular with amateurs and beginners into bird photography but they will soon realise the lenses limitations and see why 500 and 600mm F4 lenses are popular with professionals and wealthy amateurs.

I am lucky enough to own the 300 f2.8 and 500 f4 lenses and i realise its a big investment but i think Canon should have followed Nikon's lead and made a 500 or 600 F5.6 DO rather than these F11 lenses.

If you crop the 400 f5.6 to have the same angle of view as the 800mm lens you also magnify the noise. This magnification is equal to increasing the iso 2 stops.

F11 at 1/200 would give 3200 or 4 times less light

If you are going to crop a 400mm image down to 800mm equivalent, you’re throwing away 3/4 of the incident light, hence the total number of photons used in the two situations are exactly the same. The difference is that a 400mm F5.6 lens concentrates all the relevant light onto 1/4 of the sensor area with the rest being completely wasted, whereas an 800mm F11 lens projects the light at 1/4 the average intensity over the entire sensor.

In the former case, individual pixels see more light, which improves noise and may help with focusing, especially in low light. The downside is that there are only 1/4 as many pixels, which hurts resolution and also possibly make the tracking of small objects (like bird eyes) less precise because shapes are harder to recognize.

In the latter case, individual pixels are darker and therefore more noisy, and will cause AF to start faltering two stops earlier. As a tradeoff, more pixels are trained on any given object, which improves resolution and may also possibly improve focusing accuracy when AF does work, as well as overall noise when downscaled to the same pixel count as the cropped version.

These are just hypotheticals, of course. In absence of an actual product to test (sensor and lens), it is not a priori obvious which alternative is going to deliver better results.

I wonder if it matters at all whether the camera is able to track a birds face or its eye. Wouldn't both fall within the depth-of-field at usual shooting distances?

It doesn't do magic. But if there's enough Birb in the picture for the software to work, then I guess yes. There might be the one guy again, though, who complains he couldn't track the Bird 500 meters away with his 15mm lens.

"might"?

At least for me, focusing on the head (not beaks) is good enough

Re: How did I miss this? Bird eye detection?

I think it will be more of a gimmick than a very useful feature.

I can definitely see it being able to track a birds eye when it’s perched in a tree or something and you fill the frame with the bird, but for BIF when it doesn’t fill the frame I doubt it will work. 
Even with the largest of birds, bald eagles, pelicans, great horned owls and herons the eyes are very small. If you have to crop your images most likely the bird is to far away for the auto focus to be able to lock on to a eye and track it.

I would love to be wrong and for it to work but I don’t think it will

Body and eyes tracking on animals should work. Anyways its all new technology so lets wait and see
