That's right. This was a standard measure in the era when there was no anti-flicker function.
Fortunately, there was an example.

1/160s.

1/40s.

It has been significantly reduced.

However, 1/40 is too slow for indoor sports.
Even when shooting landscapes, I had to take a tripod with me until image stabilization was introduced.

For reference: 1/160s, anti-flicker.


It has been significantly reduced.
This was taken with the 7RIV, which doesn't have a high-precision shutter function, so this is the best I can do.

As a side note, this is a special spot for cherry blossoms that bloom in winter, and is a favorite place where you can see autumn leaves and cherry blossoms at the same time. However, the drawback is that the frequency of the LED lighting varies dramatically depending on the location, causing flicker.

A focal plane shutter in 35 mm film photography has similar distortion as a digital sensor that reads line-by-line.

NZ price has been announced at $NZ 11,099. So a little less than my guess of $12,000. But still far too high for my budget.
So I'm not in the market for the new camera.

It is €7000,-over here. I feel that is in line with the US price: $6000,- is €5600 and with VAT added (20%) gives €6700,-

More then I am willing to pay, so I'll stick with my A7r4

Interesting- $US 6000 is about $NZ 10,000 and with 15% GST, would be around $NZ11,500. I will be sticking with my ɑ1, like you're sticking to the ɑ7r4. The ɑ9iii has some tech and abilities I'd really like to try, but not enough to pay that price.

The UK price (I saw £6099 at Wex) is higher than $6000 + 20% VAT by around £200. I'm surprised they didn't go for £5999, but even so the A7 III is going to remain by my side.

Thank you, gigo, for attempting to check LA-EA5 compatibility. I laughed to think the young are not aware of it, but it is a natural thing.

The fast global shutter might make an STF mode easier to implement. The bokeh shaping of leaf shutters is still an advantage.

OK, I concede to the engineers and will say it's an interesting development in sensor technology.
I am however still having difficulty with the use case.
As I understand it, this is aimed at sport photographers.
I have yet to see a baseball trophy with a figure bunting.
As a visual art form, things come down to composition, story or drama, and in the case of sports; gesture and or movement.
A racing car without movement looks parked. The interesting bits of sport gesture is at the ends of the movement arcs where motion is lowest and tension at its highest.
It's at the height of the jump, the stretch of the throw or swing, the reach for the catch or block.
Even the dramatic interruptions (tackles, checks, collisions) are sudden stops but with movement.
It would most likely be useful in advertising with controlled dramatic lighting for advertising sports, but there doesn't seem to be a shortage of options for that use case.
Like many others at $8,299.99 + 13% HST CDN$ it will not be in my stocking this Christmas.
But it is nice to see Sony introduce a "Pro Capture" feature finally in it's product line-up. It really is over due.

I think the issue with the a9iii is it looks to be more of a niche camera. Its feature set will appeal to people who need to photograph or video fast-moving action. But it's simply too expensive to compete against the more general purpose cameras. I'm sure there is a market for it, but suspect that market doesn't have a strong presence here on Dyxum

I'm certainly not in it . I'm not ready to give up 50mp images to shoot at up to 120fps...

A perfect image at 24 mp is better than a near perfect image at 50. Atleast that was the argument I believe I was given by some on this forum when I mentioned the a7rv had better autofocus than the a1. I have both. And yes the a7rv does have better af than the a1. But it was argued by some including yourself that the a1 had blackout free and did 30 fps. Your argument now is confusing to me as a7rv has more megapixels than the a1🤷‍♂️.

The a9iii is going to get all the latest goodies the rv has. It’s going to be an af monster. Even at 24 mp I can see the utility of a camera that rarely misses and can do up to 120 fps. Truly groundbreaking. And for the record I like mp as well. It’s why I reach for the rv much more than I do the a1. So in a sense I agree with you wetapunga.

It's not so much about maximising the MP, but having 'enough' MP to do large prints for sale. Most of my photography is still landscape photography, where I'm focusing in manual mode. I shot for several years at 24MP with the a900, but I now wouldn't go below ≈40MP for landscape work. 50MP is more than good enough. 24MP is just too limiting. I've been there.

The high frame rate of the ɑ1 does suit shooting small NZ birds flitting about in forests. You can get in a burst of many more shots, in the fraction of time it's in view, without being hindered by blackout.

I don't doubt that the ɑ7Rv is also an extremely capable camera and was my first choice, unless I could find an ɑ1 whose price was similar.

Definitely, it should be amazing photographing everything from flying birds to flying insects! All the times I was thwarted in the past shooting flying bees could be solved. I'd really like to try the a9iii.

However, the economic equation is I get income from my landscape and event photography (and occasionally videography). I don't get income from my birds-in-flight pictures. That's more recreational. The a9iii isn't going to make me a better landscape or event photographer. It's just too expensive and doesn't map to my needs better than the ɑ1.
