Ok that kind of stopped my stroll down the sidewalk.
I couldn't imagine really trying to pick from the 12 frames in a 1/10th of a second...
ooof.

The R3 can do a RAW burst at up to 195 fps. Useful for water drops and not much else for me.
Impressive .... Sony has been leading the way for a few years now in my opinion, especially for wildlife and sports photographers. I think Nikon is catching up a bit on their AF. The new A9III also features Pre-Shooting where it captures frames before you press the shutter in case you miss something by being a tad late. Olympus has had this feature for a while.
I have been very tempted to switch to Sony several times but have resisted due to so much I have invested in Canon lenses.
If Canon doesn't already have something similar in the R1 to compete we may see it delayed further and or Canon taking a bit more of a market loss to Sony.
I think Read the a9III can do 1/80,000 shutter speed and sync with flash at any shutter speed too ..... that is beyond freezing Hummingbird wings although a lot of light or really high iso would be needed. Amazing technology and only $6000. lol.
Sorry, you don’t get both.
1/80,000 is one frame only.
Drops to a paltry 1/16,000 during continuous shooting.
Global shutter and the sync speeds is very cool.
As for 120 fps, not to be a cynic but I am waiting for the caveats. Sony RAW files are usually 2x their MP.
So, 24 MP x 2 x 120 = 5,760 GB/sec. A9 3 still has Type A CFe cards. They are not coming close to keeping up. I know what my RAM sticks for my desktop look like. They have heat sinks, etc. you aren’t fitting those into a camera body. At a minimum the burst is going to be limited. I very much wonder if other crimping of files will take place. I mean, even if they dropped 32 GB of RAM into the camera, that is 5 sec burst until filled.
Anyway, very happy to seen Sony innovating. Very happy to see a global shutter.

:( Did not know those limitations, regardless I am staying put (cost is prohibitive to replace my current kit with all Sony) but still impressed with specs and their AF performance.Quote:

I did not know that, I haven't installed the latest firmware update but, RAW Burst Mode isn't on my R5. Maybe it's included in the most recent update. Thanks for pointing that out.
I haven’t seen it go by, but I haven’t looked recently either. Even the M6II has a pre buffer mode (RAW burst if I remember correctly). Anyway, classic canon, they are beta testing on their lower end models and “the best” makes it into the top end.
I say Classic Canon as there seem to be two philosophies in play…Sony leads in specs and introduces new tech/specs in their higher end gear. Canon introduces new tech in lower/mid gear. The top end typically only includes features that are rock solid dependable.
Btw, watched a video, A9 III hit buffer before my 2 Mississippi count. I’d say 1.6 -1.7 seconds or so. With writing to card, I am guessing it is 8 GB of RAM onboard the A9 III. Still impressive. But typical CFE Type A card write speed will limit you to “only” ~12-15 fps after that. So a great feature for certain instances where you can burst, wait for buffer to clear, burst again. And, considering having to sort 120 fps, maybe that is all you want.
But that buffer will still be very useful if someone sets the fps to 30, 50, etc.
Big picture, these are features I am glad to see out there.

Yeah ... the frame rate of 120 per second isn't something I want but the idea that, even for short bursts, a global shutter can function at that speed is amazing. I am usually a short burst shooter even on birds in flight and 30 per second seems more than adequate. For birders, I am still of the opinion that Sony is leading (in terms of features not necessarily image quality:cool: )
The manual doesn't mention the raw-burst capture rate, but according to the web, both are 30 FPS, with ~0.5s pre-capture, so 15 images from prior to your shutter press, and on the R7, up to 2 seconds after shutter press until the buffer fills, giving you 75 shots over 2.5 seconds. I didn't see a buffer size/max capture count mentioned for the R8.
Note to get the image out of a raw-burst you need to use DPP, or extract it from the burst in camera, as the whole burst is one big file.
Not quite A9III performance, but it's a budget camera, and it sounds like Joel would be happier with the image count too.
The "pre-capture" feature is something I would like but not enough to buy another camera body right now.....maybe it will be implemented on the R5.
I also didn't know you had to use DDP in order to get an image out of it. That is a bit of pain in terms of workflow.
I had lots of glitches with DPP, stopped using it.
Appreciate all the detailed information from everyone....takes an effort to keep up with it.
Just noticed the native ISO range of ISO 250 - 25,600. I have seen references to 120 fps officially lasting 1.6 seconds (my count was pretty good!), a bit more noise than usual at higher ISOs, but not awful noise.
I am not trying to be too critical of the A9 III, but just trying to get past the headlines. From my perspective, the programable FPS is probably the feature I am most interested in but is also the feature I can see getting me into the most trouble. Respect....but no thank you. I like the idea of no flash max sync speed. But, whenever I am using flash, 1/125 - 1/200th is my target shutter speed anyways, 'cause, you know, I need a flash because there isn't much light. Max shutter speed of >1/8000, again, sounds amazing...except even on bright days I usually max out at 1/4000th. I do occasionally see wobbles with electronic shutter, but a faster readout speed will likely solve that.
Actually, the most impressive thing I may have heard about the A9 III is how people are raving about the AF system. I always need/want a better AF system.
But, then the negatives, CFE Type A cards...no. RAM of 8 GB...that is likely the same as my current R5, so actually not that impressive. Native ISO of 250 to 25,600. I could say what I care about is how clean the ISO is, but I am often using ISO 100 even ISO 50 on bright days. And there are reports (granted preliminary) of some slightly increased noise. So, no thank you.
I often fall back by thinking of % of pictures a new feature would allow me to get. I have no doubt I will buy a new camera someday; I enjoy gear too much. But I fully admit my R5 has a very small % of images that I try to capture where it can be improved upon. Next gen AF system, 14 bit for all files, not changing fps with battery life, control over fps in electronic shutter, better control over video button, a legit pre-capture mode, a few things like that. And, if they can get better IQ...somehow...always better IQ. But the R5 is a beast of a camera. I am very happy with it.
Global shutter comes at a price – noise. According to DPR, Sony claims the a9 III, "...doesn't compromise on ISO performance or dynamic range." Giving them the benefit of the doubt, I suppose they mean that at base ISO the sensor is no noisier than, for example, the a9 II...at the same ISO value. However, going from ISO 100 to ISO 250 on the a9 II costs a stop of DR, and the DR of the a9 II at ISO 100 is already a stop lower than the R3 at ISO 100. Oh, how the times have changed...Quote:

The "solution" is to have on-chip and even in-pixel memory. So the data from 24 MP is instantly moved to memory which is they read sequentially by the processor. If that memory is located adjacent to the pixel well, it is taking up surface area on the sensor, so you actually are using less than the full sensor surface area (apparently this has been the case with several sensors), smaller pixel wells (which might lead to a smaller ISO range?). The other option seems to be having the memory behind the pixel well, so the sensor surface area is unimpeded, but you have more distance between a heat sink at the back of the sensor and the pixel wells. Either way, by having on chip memory, you are adding a step to the process and each step increases noise.
Or so I read/watched.
In a way I am glad Sony did this: 1) push the envelope; but 2) mentally, I am now only really looking for faster read speeds.
I'm sure we'll see a global shutter from Canon at some point. Canon is definitely not an envelope-pusher when it comes to sensors. Personally, I have not had any issues with rolling shutter effects on the R3. The readout speed is nearly as fast as a mechanical shutter. If Canon brings a stacked sensor to the 5-series, that would give you what you want (or...buy an R3 :cool: ).Quote:
