Good to know they're maintaining the backward compatibility with A-mount lenses. Thanks.

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.

I found a new showroom report. (Japanese)

@C_N_RED_AGAIN

I think it may suit your photography really well. I will be interested in your impressions, especially in relation to the a1 and a7RV. It’s just too expensive for me to get as a “second camera” just for action, and it can’t fully replace my a1 with its lower MP. I guess all that breakthrough technology doesn’t come cheap…I’d love to be able to justify its purchase 🙂🙂

I’ll probably buy one. My neighbor happens to be disneys photographer here in florida and his agency uses Sony. So I will get to test it out first before I buy it. They’ve been battling banding issues for years and his agency already told him they were getting multiple a9iii.

@C_N_RED_AGAIN

That sounds quite amazing. I suspect the ɑ9iii will allow action-photographers to try shots they hadn't considered feasible before.

Are you tempted by the camera?

Saw a video today on you tube. Fro knows photos. He got to play with the a9iii quite a bit. One sequence he was photographing very competitive ping pong players. With the 120 fps burst rate he was able to get a photo of the ping pong ball and its label perfectly sharp. Was really cool pic. Not sure shots like this were even possible before. I can think of tons of uses for the global shutter. This is as ground breaking as the original a9 stacked sensor

It would only be blinding if the photographer insisted on very high flash levels combined with those very fast shutter speeds.

I'm trying to imagine the setup courtside at Wimbledon if allowed. A $100,000 in power units and a couple dozen full power strobes,

There is no reason for flash sync at 1/80,000s at Wimbledon.

Check out the Tony Northrup review of the a9iii about 5 minutes in.

Yes, and he states that it was operating at minimum power in order to sync at 1/80,000s. I think that's only 2.4 WS - which is not very bright. Using a big bad uberflash just seems like a piece of showmanship. As I was saying, the actual usefulness of flash sync at 1/80,000s is rather limited.

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.

If you're trying to light something at ISO 100 and f/8 for such a short duration, you'll need as much light as possible. A normal flash puts out very little power in 1/80,000 of a second ... so to get the required number of photons to do the job, you might need several flashes fired simultaneously, which could be rather bright. But the bigger issue might be the number of flashes required.

In practice, though, I don't think there will be many situations that require that set of shooting parameters.

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.
