Slight edge to R3, according to him.

Happy news for the customers of both companies. Stiff competition benefits us all.

Thanks aftab

As a R5 user, I am hoping some of that AF will be available in the upcoming firmware upgrade.

Frog is a funny guy:-) Interesting that Sony does so well with 50 MP and great that Canon caught up

Now, it would be interesting to see how Z9 AF performs in real life. I think the difference between the top 3 will be insignificant and barely discernible.

Most likely.

Sony actually is able to scan faster than Canon despite having more MP. I wonder if dual pixel architecture demands additional calculations/processing for image formation and thus offsets some of the advantages of lower resolution.

Definitely, dual-pixel means having two read two photodiodes for each pixel. Processor could definitely handle more (as R5 already does), but the sensor is the limiting factor here.

It's not coincidence that:

45mp * 20fps * 12bpp ~= 24mp * 30fps * 14bpp

They do almost the same data rates if you factor in the bit depth too

I think Sony has always been prioritizing humans in general, whereas Canon is better for animals. Not only that it has Animal eye AF in video, but the AF points snap on more distant subjects/eyes, right? And I don't see it jump from one resolution to another in the EVF every time it auto focuses... not at least from what I can discern by watching those videos.

Watched with great interest. Key take away is to know what resolution you want before comparing. I cancelled my R3 pre-order after deciding 24 Mpixel was not what I wanted. I’m not doing pure human based sports anymore and BIF is my fast frame rate / high speed AF driver so I want the higher resolution. Got my A1 about 2 wks ago and also have the R5 so a 45-50 Mpixel camera is what I want. Will the R1 offer that and if so at what price?

want to get a look at the Z9 only for comparison. Don’t own any glass to use with it but it’s attractive price makes it interesting. It’s large size and weight are it’s downside I think.

All I'm Hoping For

is that the new firmware update for the R5 will provide stickiness of the focus we see in this test on the R3 will be translated to the R5. I believe it IS possible. Can't wait to load it and check it out.

Name the gear and I've probably owned it and used it.

The R3 af is working differently to the R5?

Anyone else notice that he's using expand spot/area and it's picking out faces and tracking?

That's exclusively on R3 and not supported by R5/6 (for now) meanwhile any spot/area can be initial start for tracking.

Yeah I got bit by a bit of the Nikonitis. I was a Nikonian for over a decade before making the rounds with several others and finally heading back to Canon. That sweet Z9 body is exactly what I wanted to be checking out with all it's pro tendencies of button placements and speed. I'm hoping to be one of the first wave receiving it so we'll see. I would certainly report back my findings

I saw that when he posted his RAWs from the R3. Wonder why he is not using Human Eye AF?

He is. The R3 allows face/eye detect in any focus mode.

That is what the R5 should be doing.

There is no real excuse for the two modes

It confirms my suspicion that the R5 has been crippled, made inconvenient to use well. I find that small spot AF, in macro is very accurate, but tracking (no eye) very rarely chooses the same place.Canon has told me that Tracking  AF is designed only to work properly , for face and eye

So two button AF users like myself are fooling ourselves using small spot AF to 'prefocus', tracking mode, as they work independently. Tracking uses a initial focus spot twice as large as small spot focus, even though in eye mode, tracking can use a spot half the size of small spot AF.

I use the diagonal grid as a cross hair and can position the spot very accurately. on the same place, tracking pretty well always decides to wander off.

If it was in any way linked to the small spot, it would stay there

You never know the new firmware might improve things, but I doubt it.
