I saw the release info about hte new Sony Alpha 9 III a couple of days back, and thought I'd take a look at it in a bit more detail.
To say it is gobsmacking is an understatement. The big news is of course a Global Shutter - no more wavy lines. This also gives users the option to use flash at any speed, but it wasn't until today that I actually saw what speed that is. 1/80,000 of a second.
Anyone here got hand-shake?  Whilst I can see that with flash it could be great (although a bloody big flash would be required) could anyone imagine photographing anything at that speed? How much light would one need?
Just as a matter of interest, I calculated that light would only travel 3,747 metres in that time - 2.3 miles.
I guess for scientists this could prove a real boon.
The other specs on it seem to be pretty mind-blowing as well, as long as one remembers that the camera remembers faces, so data protection laws could be a bit of an issue.
...Of course, this is totally academic to me, as I couldn't afford the strap for the beast, let alone anything else

Could be useful for insects in flight and other action shots of beasties. May also be of interest to folk that use really wide apertures on really bright days. |

120 fps in burst mode. Id struggle to take that many frames in a day shooting wildlife.

Even on a bright day and an f/1.2 lens , you'd have to have the ISO cranked up , I think . As far as an insect in flight goes , to to use anywhere near 1/80,000 second exposure the aperture would have to be that wide open DOF would give you an essentially out of focus image , just one thin slice in focus . I doubt having a flash in use would give enough light out at the typical working distance for most flying insects to stop the lens down much . |

I don't know how spray pray enthusiasts do this at even modest burst rates but I guess we are only a step away from AI assisted sorting where, after a couple of iterations, the five will emerge from the tens of thousands. I didn't read the press release yet but I guess the ability to read and process sensor data this quickly opens the door to better AF tracking and that the headline achievable fps is mainly a come along. |

Let alone deleting all the duff images taken at 120fps, think of how long it would post-edit the only shots you want to keep... |

That's an already available feature on smartphones. Take a burst and it selects the 'best' ones. |

The Nikon 1 had something similar - took a load a pics and saved what it considered the best 5.

When the right to publish a photograph is sold then often the deal restricts the selling of rights to that photograph again. It seems we might have several versions of a critical moment each shot within milliseconds of each other. There might be money in this for lawyers.
