The announcement is tomorrow but apparently the A9III will have a global shutter - https://www.youtube.com/watch?v=r27i_86bwrs

I'm sure this will make some people very happy. Personally, I don't know if it is the optimal choice for me if there is a trade-off with high ISO performance and dynamic range. I'm kind of fine with the readout speed from the A7SIII.

But it's definitely exciting to see what sort of implementation Sony has come up with! Maybe they've solved some of the issues related to global shutter. They've certainly been tight-lipped about this development. Usually we'd hear news like this at least a month in advance.

Looking forward to seeing what they come up with in terms of DR and whether they put it into an FX cam. Planning on going to the event Wed -- are you, Abe?
 
That would be a big deal. Especially if there are not any drawbacks. Sensor tech is basically the camera these days and Sony is in the best position the lead the charge. I am silently hoping for a 1" sensor camera release someday with more current specs. An RX10 28 or so. Something small and useful to compliment my A-series cameras.
 
It would be cool if they started experimenting with f/1.8 fixed-lens camcorders with MFT sensor sizes, but not going to happen.
 
Yes, it seems the days of a wide variety of camera sensor sizes are past. I find quite a few video uses for my RX10 II but want it to be more modern.
 
Wow this thing is a game-changer for photo. It can pre-capture for 1s at 120fps 14-bit 24MP. Looks like with the buffer it can shoot 120fps stills for 1.6s.

Its shutter speed goes up to 1/80,000. And it can flash sync at any speed up to 1/80,000. That's nuts

mmm... 4k120fps with no crop...

Interesting. A9iii claims 8 stops of IBIS. A7siii claims only 5.5 stops. Maybe sony is finally uncrippling its IBIS?

$6k, available next spring. More than the $4500 predicted, but totally reasonable if it's for you

A1 and a7siii are getting a firmware update next spring. Breathing compensation for a7siii. No mention of variable shutter but who knows

Sort of funny that they're bragging about a planned firmware update for the a9iii itself. Another way of saying it's going to be flawed on release

Anyway, no mention of native ISO/s or DR performance. That what i need to hear about. But since it's not available for another few months, it's no big deal. I can wait to see what other cameras Sony announces over the next couple months before making a choice.

Yeah, but no FX announcement. I'm sure you're happy with the a7siii fw update, Abe...

yeah, more or less. what I really want is variable shutter.... it's unbelievable that the camera doesn't have that.... but breathing compensation I have found to be useful on the a7iv when shooting high-magnification slider shots with the 35mm GM. That lens breathes so much! And with the focus behavior of the camera, the shifts can be quite sudden.

But if Sony is going to release an a7siv, there's a chance I will sell the a7siii. I'm not sure. I probably don't need more than 4 mirrorless cameras. I currently have 3. I don't know what my lineup will be in the future...

I was hoping for an fx3II. I just bought the BM 6K FF and the sensor smearing in low light is really terrible: https://vimeo.com/manage/videos/881940044 I expected some grain but this was unexpected. There CS is great, but putting out a sensor with these problems is crazy in 2023. Probably returning it (barring a life saving FW update from BM) but don't know where to go from here...

Hmm I guess it depends on what need you're trying to fill. I'm committed to living in a Sony world because I have a bunch of their lenses, and their image quality is already good enough for my needs basically. So, I personally wouldn't buy another brand on the basis of IQ. And it's hard for me to imagine Canon or someone else coming out with camera tech that thrashed Sony's so roundly that it was worth it for me to lose thousands of dollars switching brands. If anything, Sony would probably catch up to them in short order.

The b&h product page for a9iii is out: https://www.bhphotovideo.com/c/produ...%20md_5722.jpg

Still no mention of native ISO or dynamic range.

One troubling thing I noticed -- you can't record 4k120 in the s-i all-intra codec. That would be a problem for me because my biggest client demands that codec. Which puts the a7siii/fx3 at an advantage in that regard. Relatedly, the a9iii only does full sensor readout up to 4k60, it seems. I assume that to do 4k120 it does some sort of pixel-binning. Not the end of the world, but again the a7siii does that better.

All in all, given that I don't really need a global shutter and that I prioritize high-ISO performance and dynamic range, this probably isn't the camera for me. Let's hope that the video-oriented cameras Sony announces next also boast 8 stops of IBIS...
 
Abe, what about a used a1? 4K XACI-I @ 120 fps looks great. It would probably cost less than a new a9iii. I've been very happy with my a1 and use it for video more than I ever expected.
 
Base ISO of the A9III is 250. I think the normal range is ISO 250-25600 but I can't find it in the DPReview article anymore. Base ISO for S-LOG3 is 2000! That is pretty high and will need quite a lot of ND in sunny conditions. Still much to find out about this new offering. It could be a game changer or it could be a nice attempt :) This is the first real round of global shutter sensors, so it will get better. Hopefully by the time I want to replace my current cameras.
 
Wow, think of what this new sensor is capable of outputting in RAW:
- Full Frame Global Shutter
- 6000 x 4000
- 120fps

Then get it packaged into a video centric body!

As it is implemented in the A9III, you could even shoot continuous 24mb 4:4:4 14-bit still frames internally and then use those to create a video rather than traditional XAVC or external RAW

Kind of relieved they didn't intro a new cinema body -- now I don't feel compelled to sell my fx6 and by something new ;)
 
"Global shutter technology requires extra circuitry on the sensor, usually in a space normally reserved for collecting light. With Sony’s stacked CMOS technology however, this circuitry is in a 3D arrangement sitting behind the light collecting photodiode layer of the chip. This means, in theory that low light performance and dynamic range aren’t impacted by it. Whether this is really true remains to be seen when the first reviews of the a9 III drop in Spring 2024."

From EOSHD

If this explanation of the technology turns out to be correct and there are no low light/DR penalties.....wow
 
Just came back from the Sony Creators event. Really cool. I had a long conversation with Sony's Cinema Line Product Mgr. No FX6II or FX3II for a couple of years. No immediate plans for an fx9II. They're going to eventually implement the global shutter in their cinema line. I have his email, so I'm going to ask him about E-nd in the fx3II and IBIS in the FX6II, as well as shutter angle via firmware implementation in the fx3...
 
Sounds good. I'm keen on a device that has both eVND and IBIS that is not at the price point of the Murano
 
Thanks for the insight, scorsesefan .

Any updates on whether they're considering a true S35 cinema camera? I.e., something in a proper body with internal NDs and the usual connections? I love my FX6 but when people started speculating about an "FX60" I was more than a little intrigued by the idea.
