What we don't know is how far along Canon is with their Global Shutter sensor. If they are still experiencing poor noise and dynamic range, would they still release it at that time? Sony had to make a decision on just when it was good enough to release. Is Canon at that point too? We don't know.

I think we can also agree that getting global shutter to actually capture an image is likely the easy part. Getting the IQ they want is the hard part.

This PetaPixel Podcast covers many topics, but the main topic is the Sony A9III and global shutters in general, and they discuss the pros and cons of a stacked global shutter when it comes to base ISO, high ISO Image quality, noise and dynamic range, with reports from around the world.

If you want to start with the A9III and global shutter discussion, skip to 32:50 minute in from the beginning. The entire Podcast runs 120 minutes long.

Some of what they say is the most info we know yet on this subject, and whether we will see other global shutter cameras on the market and from whom, and when.

Reports now from Canon sources say the coming Canon R1 ( spring 2024) will NOT have a global shutter, but will have a new fast stacked BSI sensor.

Here is a reality check.

I would need to use 1/8000s at f/2.8 ISO 250 (the A9 III base ISO) in direct sunlight. I can do that now with the A7 III (also 24MP) but its base ISO is 100 so I have some flexibility.

If I use a shutter speed greater than 1/8000s or an aperture smaller than f/2.8 with the A9 III I would need more light (more than broad daylight?) or each result would be underexposed unless I raise the ISO. At 1/80000s I would also lose about 3 stops of dynamic range.

Thank goodness it's priced out of my range.

Your understanding of the possible settings in different situations of light and/or flash with the A9III vs an A7III is a total misconception, unless you know all the variables of all subjects you are trying to capture with respect to Depth of Field, lighting ratios, stopping or showing motion, trying to overcome the daylight, shooting under artificial light, flash sync speeds and how to make the most of them, and countless other variables.

Do you really think you know all this better than the Sony engineers who worked years designing this A9III, and better than all the pro sports, news and wildlife shooters that are ordering this camera around the world, happily spending $6k USD for each A9III, and who will be using A9III at the Paris Olympics, and are already making creative A9III shots they could never creatively make with any A7III ($2200 USD), which yes I have owned.

In fact, many pros have said publically they would have gladly paid even more than $6k to have all the creative advantages this A9III camera has.

As a longtime Professor of Photography at a state university, a pro photojournalist of over 50 years in the business, and with a Masters Degree in Digital Photography I think I understand the physics, and know how revolutionary and game-changing this A9III is .

FYI, I have owned Sony A6500, A7RII, A7RIII, A7III, A7RIV, A9, and currently own A1, A7RV, A7SIII. And this A9III with either its base ISO of 250 or its adjusted low ISO of 125 can creatively make shots that other Sony cameras can not creatively do, just the facts, just the physics.

It will all become clearer to you as more pros ,testers and top youtubers put it through it paces with full production models in more situations, and show you what the fuss is all about. Shots that you will NOT be able to pull off with your rolling shutter BSI sensor A7III at any ISO, sorry .

Please do better research.

Hang in there.

Cheers and best to you.

(quote) Why Hate the Sony A9III ? This Nikon guy appreciate this monumental moment. What''s with all the Sony A9III hate out there? What's with some channels dissing Sony's monumental achievement here? As a lifelong Nikon photographer as I am, let's talk about this. We should not hate what Sony has done here? We should not downplay or lessen the A9 III and what this means. We should give major credit where credit is due.

As a Nikon photographer owning many F, D and Z cameras, I do just that. We should not hate or downgrade this monent, instead we should say - "What does this global shutter on the Sony A9 III mean for future Nikon photographers". and also give credit where credit is due.

Let's get into it. (end quote)

I have a pretty good handle on the different light situations and depth of field. Here are a couple of examples where you might expect to be using the A9 III with the lens at f/8 for good sharpness and DOF.

Notice the ISO required to deal with these two light levels. They are both pretty high. When it comes to night sports the shutter speed has to drop to 1/1000s and the ISO raised to 25600, the A9 III maximum. These are not optimal ISO settings.

As for flash photography, remember that the flash duration on most speedlights is between 1/400s at full power, and 1/20,000 at low power. An 1/80000s exposure is not going to capture all of the power of a normal flash. It will only record a small fraction of the full power burst. You might as well get hit by lightning.

As for all of those other variables and situations, let's wait for the hands-on reviews. Don't get taken in by a shiny new object.

Who told you the A9III will only shoot flash at 1/80,000 sec. LOL

It will shoot at any sync speed the photographer choses for any flash duration of their strobes .

You are making an issue that isn't an issue. Photographers already have used it with single and multiple strobes at various flash sync speeds up to and including 1/80/000 second with excellent results photographing models and moving athletes . That was shown in some of the first videos released by independent youtubers at the Sony launch event in NYC.

Check it out.

Cheers and best to you.

Nobody!

I was just pointing out how incompatible flash is with one of the camera's major features. It's going to take a lot of strobes to squeeze enough light into 1/80000s.

There are lots of things we are going to learn about this camera once it becomes available.

There is nothing about it that tempts me to buy. I just hope you don't waste any money on it until you are sure of its benefits.

What I see is that this camera is going to get used a lot at the Paris Olympics. Add the new 300 mm lens and you have something that the professional sport photographer will want.

The lowest ISO setting is 250. That might cause some issues in lower light situations.

I can see wildlife and bird photographers liking the speed that they claim this has. I think it was something like 120 fps.

I think everyone would like this camera, but I suspect that to get the full functionality, you'll have to upgrade to ultra fast memory cards that no one has discussed.

I'm sure that down the road, when this global shutter becomes common a camera might be produced in a price range that fits the average photographer. Until then, It is way beyond my budget.

(your quote) "I was just pointing out how incompatible flash is with one of the camera's major features. It's going to take a lot of strobes to squeeze enough light into 1/80000s."

No not really. Look at top pro and youtuber Manny Ortiz' video from the Sony event using a single on-camera strobe and shooting flash photos with the A9III at 1/80/000 second, no problem.

Like I said, please do better research, the answers to your misunderstandings are already out there.

Better informed and knowledgeable professional and hobbyist photographers than you have already pre-ordered the camera around the world, and they will gladly make great use of all its creative and revolutionary advances. With pre-orders alone, it is already a "Top Seller" at B&H Photo/Video, the biggest selling camera store in the World.

As a professional photographer with 50 years in the business, and also as a longtime Professor of Photographer at a state university with my Masters Degree in Digital Photography, I fully understand the physics here as well as the practical applications and advantages of a global shutter. I currently own pro Sony A1, Sony A7RV, Sony A7SIII fullframe mirrorless cameras, and may add this A9III too for what it can creatively do that my other top pro cameras can not.

No camera is perfect and none are perfect for everyone's needs . It is fine if you have no need for such a revolutionary camera at this price. Many wont need this camera and what it can do. That is fine. Sony isn't making this for everyone, but for those that will benefit from it, it is money well spent.

Just know that Canon, Panasonic and others have also been working on this for years, and are close to releasing their own fullframe global shutter sensor cameras. As more come to market and in different price ranges, more will be able to know and to embrace this revolutionary technology in the future, maybe even you one day.

Cheers and best to you.

I have no problem with the global shutter. Sounds like a nifty idea that solves a couple of annoying problems.

But the ultra high shutter speed may have some side effects that aren’t that easy to live with.

gwilliams6

Sorry, but you are still misunderstanding the applied physics and practical applications of that 1/80,000 sec. shutter speed in all creative professional situations, including using flash as some fill light in bright-sunlit action and sports photography, while still stopping or blurring the motion.

Cheers and best to you.
