The older of those that don't support Silent Priority Aperture Drive in AF will have the aperture setting locked at the first frame when using 60 FPS or higher.

Thank you for the information.
I decided not to buy a lens that couldn't produce 30fps, so I was able to confirm that there was no need to replace it.

I'm at least tempted, although there is few things that make me hesitate a bit. Just noticed first price listing on a Finnish camera shop: 7299 €, which is certainly one thing that makes me wonder if I can afford to get one - even if I trade one of my existing cameras (probably α7R IV or maybe α1).

The specs (on paper) are very impressive. 120fps seems crazy fast. I mean, I remember when the a900 was released and we were kind of awed it could do 5fps as a full frame camera. I also like that it has 'corrected' the video gap with the previous ɑ9 models. You can now shoot in S-log (if limited to 4k). It'll be interesting to get some reports of actual use.

Despite the impressive stats, I think overall, the ɑ1 still suits my style better (albeit a firmware update would be really, really nice Sony!). I'd still rather have 50mp than 24MP to work with.
At least Sony has promised a firmware update also for α1, albeit only in March next year. I hope that firmware update would introduce the Pre Capture mode also for α1 since that is one of the main features that makes me dream about α9 III. That would be so nice to have when you are for example waiting for a bird to take off. The fewer megapixels might be an issue, although for years I used A mount APS-C models and I was quite happy with max 24 megapixels. And I am not giving away my α7R V, which has even more megapixels than α1...

Pro capture on a 24MP sensor? My E-M1X is fine at 20MP. Kind of a spec drop from the A1 and 7R series. Trying to position the A9 as the "professional" when the consumer line and the elitist lines are older, makes me think that a project manager will soon be out of a job.

Not to imply that it's not a useful feature, it was part of the feature set that seen me return to Olympus with the OM-D E-M1 Mk2 when Sony abandoned a-mount.
It just seems Sony isn't trying with the A9.
The Mk2 could have been done with a firmware update and the Mk3 looks like a slightly warmed over Mk1 with a 2020 release date.

Ehm, the A9m3 is a sports camera - no time for cropping, no use for big files. 24mp is more then enough.

A global shutter, an 1/80.000s shutter, flash at all shutterspeeds - this is not "slightly warmed over" this is a breakthrough.

We'll have to wait for the reviews, but a lot of people are impressed.

So.... Full time HSS is impressive? Don't you just get that by removing the mechanical shutter?

Removing the mechanical shutter on a "non-global" sensor still has the time lag by reading the sensor lines one after each other which leads to a rolling shutter effect, banding in artificial light and other drawbacks. A global shutter reads all pixels at the same time, so no rolling shutter effect and no banding.

I'm still having a problem getting excited. I can understand the occasional need for a bit more speed. I usually use my a99II at 18MP because at 42MP it tends to bog down. But if using a feature like "pro capture" I don't see where the problem is. I wish the a99M2 had a feature like"pro capture".
It's about time Sony.
As for sports, aren't flashes frowned upon?

With the practical application of global shutter, HSS has become a completely meaningless function.
Eventually, they will suffer the same fate as the long-vanished FP class flashbulbs (which provide stable light emission for long periods of time for focal plane shutter cameras).

Modern flashes tend to emit light for a long time in order to increase the amount of light, but this may change. This is because if the flash duration is long, the effective light amount will drop sharply with a high-speed shutter.

I think the day will soon come when flashes that not only can use global shutter but are also optimized for global shutter will be released.

I won't pursue it here because it's off topic, but the relationship between light emission time adjustment for light intensity control and exposure time is interesting.

Sounds like a solution in search of a problem. But if it's got you excited, who am I to say "Meh".

OK, I'm going to the Sony presentation today with LA-EA5 in my bag.

Here is an article from yesterday's venue. (Japanese)

Increasing the flash duration kind of defeats the shutter speed. Good for a well lit blur I guess. Other than that it becomes a HSS effect.

One last thing on this: At ISO100 1:80,000 of a second and F8 the flash power for proper exposure will probably be deemed to be a hazard, for eye retina damage. just sayin'

@Hezu,

I thought you might be tempted given your interests. It looks like you could get some incredible bursts of shots of birds and wildlife and really capture a decisive moment. So far the price in NZ hasn't been announced but going by the rough rule of thumb, of double the US price in NZD, I'm expecting ≈$NZ 12,000. The only way I could afford that would be to sell the ɑ1, and I'm not sure I want to give up 8K video and 50MP image size yet. Albeit the lack of rolling shutter will have some videographers very, very keen. And down-sampled 6K to 4K is still very nice quality.

I did not realise an ɑ1 firmware update was planned. That is encouraging. There's a few refinements I'd like to see brought to the ɑ1.

I agree that a lot of photographers, especially those this camera is aimed at, won't be bothered by the 24 MP image size. I was very happy for a long time with 24MP on my ɑ900 and ɑ77ii. Even the ɑ9 was still very good with a 24MP image size. Still, since having the ɑ1 I have appreciated the extra 'cropability' I get with 50MP files for birds. And it's still a better file size for landscapes. But I don't think the ɑ9iii is really aimed at the landscape photographer set
