Extremely fast HSS is indeed one advantage of a global shutter, people who need that are excited, people who don't are not, nothing new.

But the other big advantage vs "non-global shutters" is no rolling shutter when using full electronic shutter (or for video), again for some that's a big deal and major step forward and for others not. It all depends on your use cases.

But one thing is sure, it's a big technical innovation to be able to read out the whole sensor at once in a very short time and not have that process slowed down by relatively slowly reading line-by-line from one side of the sensor to the other.

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.


Quite, the global shutter really is the breakthrough many have wanted. For anyone photographing or videoing rapidly moving subjects, you escape the dreaded rolling-shutter effect. You're not going to see the images gradually skew, stretch or bend from the top of the frame to the bottom. That's really going to matter for sports photographers, videographers and to an extent, bird and wildlife photographers.

A shutter speed of 1/80,000s and a frame rate of 120fps, is going to impress any sports or action photographer who wants to capture and freeze that decisive moment. It's going to open up subjects to photograph that were only rarely and with good luck, photographed before. I think it might also appeal for wedding photographers who want to capture the perfect moment.

The a93 with global shutter is truly ground breaking. I’m absolutely puzzled why some on this thread are dismissing it as a meh feature. Anyone that shoots indoors with led lighting even with faster cams like the a1 are always battling banding issues with l.e.d. Lighting. Banding will never occur again with any cam with a global shutter.   120 fps with precapture are revolutionary. I can think of all kinds of use cases for me. I love shooting Airshow’s. I shoot about 12 a year. The high speed passes where the military jets produce vapor cones occur so fast that it’s nearly impossible to shoot. Won’t be anymore. Another scenario would be shooting diving eagles or ospreys. With precapture you only need to click the shutter when you see the bird has a fish in talons instead of wasting bursts on fruitless attempts. I’ll likely buy this even at this price. To me this is ground breaking.

Given that the buffer for Pre Capture covers just something like 1.6 s, I am not sure your example use case works. But certainly that feature is something that has been sorely missed in Sony camp as it should help to get some photos even if you are tad late for the action.

Sorry, I brought my SONY 50/1.4 and LA-EA5, but I was not allowed to use with A9III the lenses I brought because Fitmware was in beta version.

I asked about LA-EA5, but the young staff members didn't seem to know what it was...

Looks like we have no choice but to wait for the compatibility table to be released.

If you think about it for a moment, you'll understand, but that doesn't happen with global shutter cameras.
That large amount of light is required for 1/80000 seconds, not the few milliseconds it takes for the shutter curtain to run completely.

In fact, we today's guests used flash a lot in a mock badminton match, but the players didn't care at all.

There's nothing to worry about. Even groundbreaking features like AE and AF were initially met with a ``meh''.
But both people who are excited about the latest features and people who are skeptical are important and valuable people.

I also tried pre-capture. Of course, longer is better, but unless you're really distracted, 0.5s is enough. 1.6s is like an eternity.

The setting was baseball toss batting, but you can figure out the timing by watching the batter, so it's easy even with A1 without pre-capture.

If this were a whack-a-mole game, I might have thought I had no choice but to buy 9III.

That ground was broken a while back. Olympus E-M1 cameras have been so equipped since 2016.

The global shutter read speed does solve the electronic shutter (rolling shutter) ; but since I don't do video with weird back and forth panning or rarely use electronic shutter, not for me.
Flicker free would suggest to me Sony's flicker free modes on there current line-up isn't working?

Rolling shutter distortion isn't just for videos.
Even in still images, there are many things like the windows of high-speed trains becoming diamond-shaped, the shapes of airplanes at air shows being distorted and strange, and birds in flight appearing asymmetrical.

7RM4 anti-flicker off,

and on.

The function detects and synchronizes the frequency of flicker, but it takes some time to detect, the shutter cannot be released at the desired timing, and the continuous shooting interval varies as a result.It requires some skill and has many limitations.
The A1 also has a high-precision shutter that can be synchronized more precisely to prevent flicker, but it takes a considerable amount of time to adjust it to prevent flicker.

Shutter speed 1/51s.(51Hz)


What can't be done is when there are multiple light sources with different frequencies within the screen.
In the past, lights used to be light bulbs or fluorescent lights, so they were all synchronized with commercial power.However, LED lighting, which cannot be turned on directly with commercial power, will not synchronize unless it is designed that way. It is highly unlikely that multiple electronic bulletin boards will be synchronized.

It seems that many beta testers were delighted with the 9III, which does not require synchronization and is flicker-free in principle.

Not to point out the obvious but isn't the problem in those examples solved with a longer exposure....
ND and CPL, not just for day light?

Regardless; It is satisfying that in 2023 digital photography has finally matched the full frame image quality without distortion as 35mm iso100 film.
