Certainly. Indeed, so far I haven't found a good side-by-side comparison or even a site where both mk2 cameras were tested in a similar way, but hopefully links below would be of some use.

While not very scientific tests, when comparing to my experience with M6 mkII (also represented well on other Youtube AF-test videos), to me the new M50's eye-AF algorithms look improved.

Link 1 - M50mk2 Eye-AF Test around 3:40 mark

and

Link 2 - M50mk2 review around 4:15

My conclusion: The M50II recognizes eyes at a larger distance (or, more precise, with persons being smaller in the frame) compared to the M6mkII.

I'm interested in this topic as often recommended here spot-AF had not delivered on a few occasions (especially with environmental portraits, despite the AF point covering person's face, the camera focused on the surrounding foliage slightly behind - and actually very similar phenomenon was being discussed on the Canon R forum).

A better eye recognition won't help for focusing on brighter backgrounds in stead of the subject. If that's your problem, the best thing you could do is mount a large aperture lens (even if you're shooting stopped down) AND use the smallest single AF point.

The larger aperture will provide more light to the AF-system to get enough contrast to grab focus. This will help you more than better eye recognition, as recognizing the eye is one thing, but focusing on that eye is another thing. If the camera succeeds in recognizing it, that's isn't guaranteeing you it will be able to focus on it.

Of course I'm tempted to, at some point (Black Friday maybe?), just buy the M50mk2 and compare it side-by-side, but hopefully someone else in this forum has gone that (questionable) path already.

Sigma ef-m 16mm f/1.4

Canon ef-m 32mm f/1.4

Sigma ef-m 56mm f/1.4

adapted Sigma 18-35mm f/1.8

adapted Sigma 50-100mm f/1.8

Those lenses are helpful to get good focus in back lit situations. A used 18-35mm can be pretty affordable.

It sure does look like she is using the kit lens in the video too.

I am wondering how good it will work with the 32mm lens.

yes, would like someone to test with the 32 and 56

If it recognizes the eye with a kitlens it will recognize it with those primes too. So for eye recognition I don't need extra tests. If you want to know if it actually nails focus you need the actual pictures anyway, for nailing focus the given sources aren't proving anything for the kitlens too anyway.

I am thinking the M50II would do eye recognition better with the 32mm than the kit lens.

Why? As long there's enough light the kitlens should be fine.

I checked eye recognition with my M6II with the kit lens and no way no how will it do eye recognition like the M50II in the video.

We share the same conclusion. M50mkII is better for recognizing eyes at larger distances than the M6II.

My RP with the 35mm STM will not either.

That is one impressive firmware update they did to the M50II?

Firmware is exactly as important as hardware. Good firmware isn't for free. It takes R&D costs to get good performing firmware. The M50II isn't a minor update over the M50I. It's a HUGE update. Don't forget the price isn't substantially higher! If it even has the AF speed of the M6II I might prefer the M50II over the M6II. In that case I'm ready to go back to 24Mp, the only thing I don't want to sacrifice is it's better dynamic range of the M6II...

in addition the m50II has internal EVF

I'd prefer the M50II over the M6II

My testing was with a redhead girl. Could the lighter color of the eyelashes and eyebrows make a difference ?

As long as there's a good of amount of light I don't think so. For low light I think it could make a difference.

I noticed for eye recognition Asian faces can be more challenging, especially when smiling or laughing. If the camera can't fall back on the shape of the total face it can loose the eye. I think the round/oval shape of the eyes is more important than the eye brows.
