Some impressive features.
But why 20MP Monochrome?

Ebrahim Saadawi: Who holds the Patent for Dual Pixel Auto focus technology? Canon seem to brag they invented and pioneered this technology in the 70D.

If Samsung can use it, it's either commissioned by Canon to do so or it's not a patented technology, in which case one would wonder, with the marvel advances that comes with Canon DPAF then why Sony and Nikon cameras don't have it too?

@Richard Butler
The Sony-sourced Chips in Samsung's smartphones clearly used "split" pixels. There should be some kind of IP exchange agreement between Sony and Samsung.
And do we know who makes the sensor in Google's Pixel 2?

Dual Pixel sensors have been used by a lot of cell phones from several manufactures. These cell phone sensors are mainly Sony made.

Apple iPhone 7 Plus uses a new Dual PDAF system which does a better job than the traditional dual pd system in preserving light.
iPhone 8 and and Oppo R9s might be using the same system.

ozturert: Bold statement from a company whose about 85% of its customers prefer APSC.

How about profit?
Nikon's problem right now is that camera sales do translate to decent profit.

Full-frame is the right way to go. Focus your R&D and marketing resource on full-frame bodies and lenses.
The market for smaller-size sensor cameras, especially at the entry level, has been taken over by smart phones, and there is no coming back.
Canon's strategy of releasing 6-7 APSC bodies per year is outdated and shortsighted.

citrate: So many people emphasis the live-view focus function in a DSLR.
But why not just get a mirrorless camera and enjoy live-view function through a view finder?

@Dante Birchen
If you prefer an OVF, why do you value live-view function that much?

2016 is an off year, partially due to the Kumamoto earthquake.

On article Sony a9 Full Review: Mirrorless Redefined (2740 comments in total)

About the comparison between the lockon/3D focusing among cameras, I am wondering whether changing the setting from "AF Tracking Sensitivity '3' to '1,' or 'lock on.' would make a difference or not?
Since you are comparing how the camera locks on the selected subject, would it make more sense to have the setting at the highest level of lockon? Maybe difference camera systems have different tuning settings between sensitivity vs lockon.

In reply to:

citrate: Interesting.
http://www.photonstophotos.net/Charts/PDR.htm
There is another test done by photonstophotos.net. They estimated the dynamic range of A9 falling in between A7R2 and D5, but more close to A7R2.

Fuji XT-2 does not have better DR than sony APSC cameras. They are using basically the same sensor.
D750/D7200 has better DR than entire Canon camera line, full frame and APSC.
What we should compare here I think is A9 against D5 and 1DXII.

So interesting that Canon decided to release two mirrorless models with all most the same features (other than the evf) in this short time of window.

VadymA: So other than 20FPS without AF, what are other advantages of A9? I am wondering because my Nikon J5 can shoot 20FPS with AF on (!), and 60FPS with AF off. Buffer clearing seems on par with Sony as well :) So Nikon definitely has the technology and can easily incorporate it into a high-end MILC with the same or even better specs as A9 as early as this year. And with the JPEG color issues and who knows what other problems A9 may reveal, I don't see many Nikon pros ditching their systems in favor of A9 so quickly. So Sony may be helping to end of era of DSLR sooner, but not the end of Nikon / Canon dominance in the pro photography market. Just saying.

@VadymA
which camera drops to 12 fps with continuous AF ?

How big is the buffer size of J5? 20 images? I don't even know why J5 has a 60 pfs mode if the camera only has 20 images buffer size?
It is not a fair comparison to A9 in many ways.
I think Nikon is fully capable of producing a powerful mirrorless camera though, if they have the right sensor to make it work.

Is there a particular reason why "On-sensor phase detection doesn’t work any darker than F8"?
I remember A9 can autofocus at F11, with phase detection or contrast?

Canon has warmer color, extra magenta.
Similar issue with Fuji's color, and with more saturation and contrast.
Some people prefer this type of color rendering, and some don't.
I think it is perfectly OK to have personal color taste as a photographer.
But I am not sure it is appropriate to use this preference to evaluate the color performance of other cameras as a camera reviewing website.
And I don't know why and since when Canon and Fuji's color became the "standard" in the filed.
