native or adapted? which focal lengths? thx

Adapted via the Sigma MC-11 adapter. 20mm, 24mm, 35mm, 50mm, 85mm.

ive been under the impression that adapting the lenses yields crappy video AF. but good stills AF. interesting that it sucked for you on both. i'm assuming everything was up to date firmware wise
They were starting behind the 8-ball. Now, they're on top.
And Nikon is down for the count and soon may be dragged out of the ring on a stretcher.
The adapter may be the problem.
Although, of all the AF adapters, it's top rated on B&H.

I've used the MC11/a73/a7r3 with the EF mount Sigma 35 art, the 24-105 Art and the 150-600 Sport lenses (along with Canon 16-35/2.8 III and 100-400 L II) and for me stills AF has been close to a native lens most of the time when shooting photos. You get the AF boxes dancing across the viewfinder and face/eye AF locks and tracks with decent accuracy. With the a73/150-600, I had the eye AF lock onto a Great Blue Heron's eye too, and the a73 doesn't have the fancy new Real Time Tracking AF. For video its rubbish and occasionally when shooting photos it doesn't lock so it racks the focus. Its inconsistent, sometimes its really snappy and no issues, sometimes despite easy AF areas of contrast it hunts. It even does a decent job with the OG a7r's contrast only AF. Its slow, but eventually it locks. On Fred Miranda there's a user that posts BIF shots with the MC11 and two stacked TC's on a Canon 600mm lens and still tracks birds with the a9.

I also have the Sigma 150-600mm, but it's the Contemporary version. It's fine on slow-moving or static subjects in stills but misses focus most of the time on fast subjects, like birds. It's always there or thereabouts but rarely tack sharp.

Tweet from Jordan Drake:
"Spent the last 2.5 hours shooting the Canon R6 in the hot sun in Drumheller, 29 degrees Celsius. We have about half an hour of 4K/24P recorded intermittently and the camera overheated. If you require reliable recording in warm climates, both the R5 and R6 will give you issues."

Some main takeaways:
(1) Very visible difference between 4K HQ and the regular mode as previously noted.
(2) Good news: Regular 4K/30p didn't overheat for TN after 1.5 hours (also mentioned the camera didn't even get hot).
(3) Even though he calls some of the modes on the R5 "mushy" including 60p and 120p - which they clearly are less detailed in his tests - IMO, I still think they can look really nice as proved by some samples available online. I think the 4K/30p regular mode is going to look as good as many of the currently available hybrid options.
(4) Big one...R6's 4K looks better than the R5's! Including 60p. (And he thinks the R6's 4K standard is comparable to the R5's HQ!)
Puzzling video!! Good stuff though if true.

My pre-order is canceled. Multiple sources saying similar things about the overheating issues. It maybe wise to let some time pass after production units are in the hands of more people and see if any real solutions are offered up. I don't have too much confidence in the Tilta solution or that this could be remedied by firmware. Also the recording modes that are not over sampled haven't really sold me. If it turns out you can get a decent amount of record time on the R5 with the over sampled modes I will most certainly reconsider.
Actually, this makes sense, as it's downsampled 5.5K-into-4K on R6 vs. pixel binned and/or heavily compressed 4K.
FWIW, I thought Johnny Behiri's mini doc looked pretty good too. Now, there's going to be a race to find a cooling solution.
Judging from Canon's overheating chart, the 4K 60p video mode on the R6 uses oversampling, while the R5 uses a reduced sensor readout for 4K 60p such as pixel binning or line skipping. So it's not a surprise that the 4K 60p on the R6 might be more detailed than the 4K 60p on the R5.
With the 4K 30p modes, the R6 is oversampling from 5.1K, and with 4K 30p HQ mode the R5 is oversampling from 8K. It's possible that a 5.1K oversample is sufficient to resolve most of the 4K output and so oversampling from a full 8K doesn't bring a huge improvement in detail. I think the Panasonic EVA1 uses a 5.7K sensor, in part because this is sufficient to resolve 4K resolution from a Bayer sensor.
It would be interesting to know how the APS-C crop recording modes look on the R5 as these are also oversampled from a 5.1K readout of the sensor. And at least in 4K 30p, the APS-C recording times are not heat constrained.

I would imagine the R5's 4K/60p APS-C to look exactly the same as the R6's ~full-frame.
It's one thing reading the specs, and another seeing some visual evidence of clear differences when zoomed-in (which isn't always the case).
But on YouTube, no one will notice the difference when not side-by-side.

Well, it depends. I honestly didn't really expect the R6's ~FF oversampled 4K to look that much better than the R5's FF standard.
The real surprise was the oversampled 5.1K being compared equally to the R5's 8.2K HQ.
But maybe only a bit more resolution is truly necessary and anymore won't be so visible, as davedv points out above.

Well supposedly the R5 standard 4K is line-skipped...!
The quality of R6 5.1K downsample makes me hopeful that the A7SIII won't be too far left behind in detail

Is this confirmed or forum/YouTube talk? J/W
Does anyone ever know what exactly the engineers are doing in Japan? I don't.
