matthew saville: OK, it's pretty clear the A9 is worth $4,500, if you're coming from a D5 or 1Dx2.

However, it's NOT as attractive if you're "only" coming from a 5D4 or D810. Sure, the A9 might be superior, but that's still a huge price jump.

The REAL question is, ...what next? A7R mk3, or A9R?

These *could* be the exact same camera: an A9, with a ~50 MP sensor and fewer FPS.

HOWEVER, they could also be totally different cameras: an A7R mk3 being "just" an A7R mk2 but with a new sensor, and maybe one or two trickle-down features from the A9, but not all. Say, for example, still just a single card slot and the A7R mk2 AF system, but maybe the new battery and ergonomics.

The price point of these two potentially different cameras is what I'm curious about. If Sony does a true A9R, they will still not attract 8xx and 5-series shooters if they price it at $4,500. Alternately, if they price it at $2,500-3,200, they'll be angering a whole lot of A9 buyers who really didn't need $4,500 worth of camera...

I see your point but my point is that the 1DxII and the D5 are not high MP cameras but premium high speed cameras. Precisely the category Sony is aiming at. I would note that they lead with "20 FPS!!!!"

The high MP niche ironically has evolved to a lower price point evidenced in the 5Ds and the A7RII.
Trying to compare the A9 to the high MP category is missing the point.

Good points but I would note both Canon and Nikon offer lower res high speed cameras ata a premium.

Photomonkey: This should satisfy the minimum DOF fans.....if they can focus them.

@JACS. I am referring, of course , to the obsession with ultrafast lenses not because of their light gathering but for their shallow DOF.
Note that EVERY complaint about sub FF formats is the greater DOF at a given distance and AOV.
Note too, the flood of desperately close cropped images made solely to display the effect.
Back in the 70's we actually learned all the principles of format size, lens AOV and DOF. We also were not obsessed with fast lenses as they were generally regarded as nice but not a real benefit other than being able to more easily focus in low light.
We were interested in getting some decent DOF to ensure sharpness of the subject.
These lenses will sell fairly well I predict and we will have to suffer through more boring photos of faces with one sharp eye.

Ebrahim Saadawi: Article coming: warning!

The Sony A9 is not merely an evolution/tweak for the popular a7 line of cameras, it's something much more.

It's the first mirrorless camera that boldly puts an end to the SLR superiority as a camera design. That's revolution not evolution.

Up to this point the SLR was always defended by being more capable cameras due to a few elements that kept shrinking over time, but the Sony A9 checks the last few ones that remained untouched by mirrorless cameras: battery life, burst rate, buffer, dual cards, sports AF, and quick menus/buttons.

That's it. We can no longer claim the DSLR is accurately superior to mirrorless cameras per design and concept, and as time keeps going on, the very minor remaining differences will be easily tackled as well (such as more telephoto lenses and weather sealing, uncompressed raw bursts, higher-end service support) and most importantly, the Sony Alpha 9 features will trickle down the mirrorless camera concept, making it a worthy of a neck-to-neck competition with Canon and Nikon DSLRs, not just a different parallel type of cameras for a specific purpose.

The Alpha A9 is a cornerstone of a product in the camera-making industry, being the first of a product in changing the landscape of the camera choice throughout the image-makers' world, bringing the DSLR benefits to mirrorless cameras, but perhaps more importantly, bringing the mirrorless design benefits to DSLR cameras in concept, such as unlimited video-like bursts, no VF blackouts, Eye detect and large coverage AF, adaptable mounts, fullframe sensor stabilization, silent shooting, better video shooting experience with a working viewfinder, moving LCDs, peaking/zebras/LOG/custom curves/customizable buttons, and more.

Well done, Sony Co.

This is going to start an in-country Japanese war among three major camera makers. Which can only benefit you and I, the end consumer.

The real significance of these advances will be in the next couple of years as others bring these features and performance to cameras at the $1500 price point.
I dont need 20 FPS but 10FPS with no blackout and no rolling shutter will get my attention.
Of course once I can get 1/1000 sec flash sync and silent shutter I can die happy.

"Sony's looking to storm the sports photography market with its new a9 mirrorless camera."

Storm some wallets more likely.

falconeyes: > The new α9 also supports uncompressed 14-bit RAW, ensuring users can get the most out of the wide dynamic range of the sensor.

Still no lossless compressed raw.

@falconeyes. I understand what you are saying as Hensel pioneered this idea with their Freemask flash feature.
However I have yet to hear of anyone actually using it or any variation of your technique.
As flash cannot be used with the e-shutter this is a non-issue. It may have applicability with a 1Dx or D5 but again, I haven't heard of anyone really trying to set that up.

In reply to:

Photomonkey: So basically it is a FF 24MP Olympus EM-1mk2 with fewer lenses? ;)

Oh yeah, the Oly gets 60FPS.

My comment was obviously tongue-in-cheek however we cannot overlook the fact that Olympus has a very responsive camera in the EM-1mk2.
I am also aware of the µ43 vs. FF differences.
I would also note that as a user of both these formats there is a lot less difference in most typical usage than many would claim.
Yes, shallow DOF on FF is easier but as that is a small part of so many photographs.
Yes, noise at high ISOs is an issue but I have regularly shot at ISO 6400 in dark wedding venues and have gotten very usable results.
The other fact we need to look at is how images are displayed.
The VAST bulk of images are shared at 1200pixels or less. Phones do well in this fight.
If you need large prints you will need lower ISOs or FF at high ISOs. With all the whining I hear on these boards about the cost of things I wonder how many actually spring for large prints to actually see the differences.
At 11x14 and below µ43 and FF are almost indistinguishable at ISOs up to 400.

I think it is useful to remember that electronic shutters (as we have them at the moment) are really just full-res video capture.
IOW rolling shutter is present, flash is not available, and flicker in some light sources is present.
For many applications this is fine. Silence is wonderful for weddings, wildlife, candids and street photography.
Flash is still limited to the maximum sync speed of the mechanical shutter.
I would also add that when using flash, the silence of the shutter becomes moot.

Fun 4 all: How bad will the rolling shutter be?
Most A7 series were pretty lousy, some 24MP versions measuring over 30ms. The A6300 was 39ms.

And this is bothersome: Electronic shutter mode. At apertures smaller than F11 (F-numbers higher than F11), focus will not track the subject and focus points will be fixed on the first frame.

Well, it puts it in perspective.
High frame rates are the key selling point of this camera.
For me the real significance are the improvements in the finder, controls, battery and card slots.
A true global shutter with flash sync at all speeds would be a real breakthrough.

Photomonkey: " extremely low rolling shutter thanks to the incredibly fast readout speeds of the new stacked CMOS sensor."
Just how fast? As this is a camera geared to sports and wildlife photographers the 20 FPS needs to hold up to action stopping shutter speeds.

Scan speed is critical because we already have the Oly EM1-mk2 producing much higher speeds at 60 fps at full res.
20fps at 24 mp doesn't seem so impressive UNLESS it has real action stopping power.

@rrccad. Yes, in florescent light you need to shoot at under 1/60 sec or you will get banding.
This happens with my cameras that have e-shutters.
E-shutters also disable the hotshoe to prevent flash use.

CONT...

IMO Sony probably has a much higher readout speed (they certainly clim it but do not offer a spec) but unless it is blisteringly fast, it will show warping artifacts that will be severely criticized by potential users in sports and others needing action stopping speed.

@LDunn, The sensor is operating in a different manner in e-shutter mode.
In e-shutter it is effectively a high frame rate video scan.

In mechanical shutter mode the sensor is accumulating light with the mechanical shutter cutting off the light supply. THEN the read out of the lines begins and thus is not critical to the rendering of the image.

Sensor readout speeds are important in e-shutter because of rolling shutter. Thus all the wailing about video in DSLRs and cameras not having a global or mechanical shutter.

As for the 1/32000 sec speed, that is the the amount of time each line accumulates light. However it takes approx. 1/60 of a sec to read all the lines so the last line is read 1/60 of a sec AFTER the first line. So action is stopped at each individual line but the entire image can exhibit warping due to subject motion during exposure.

The camera has a mechanical shutter that is probably the same as in the A7RII. That limits flash sync to 1/250 sec.
The e-shutter has a top speed of 1/32000 sec but that is only the effective exposure time, not a measure of action stopping.
I have no idea what the scan speed of the sensor is or if it employs a different strategy altogether. However, current e-shutters read line by line in about 1/60 sec. Thus the action stopping ability is effectively 1/60sec irrespective of the exposure speed of the e-shutter.
With the mechanical shutter the maximum shutter speed is 1/8000 sec with real action stopping power.

J A C S: The skin colors are inconsistent - sometimes just right, sometimes too reddish. Maybe the Provia profile is not the best, have not downloaded the RAWs to check myself.

I am of the opinion that is shot with window light and thus is quite blue.
Blue cast will not show up obviously on the clothing or watch but the skin tone (even for a pale Seattle-ite) is very blue.
The others seem to be shot with strobe and thus are more consistent with each other.

@LDunn, Yes Jacques Henri Lartigue becomes hip all over again.;)
Actually, as you probably know, that is only true for a single subject going in one direction. If they travel the other way they look like they are leaning backward.
Also spinning blades (helicopters, swords etc) will render bent.
The real issue is multiple subjects (soccer game, hockey) where subjects are moving quickly in different directions.

@Josh, this was my question as I see rolling shutter in action images from my Panasonic GX7 and FZ1000 when using e-shutter.

I guess we will have to see how it works IRL.
Seems a brilliant camera but not what I need as high speed sports etc are not my job.
