andrewD2: The WB sensor can see light reflected from a shiny red mount ring? Make the ring neutral, it serves no purpose.

WB,sensor?
Oh you still are thinking DSL which had many small dedicated sensors because it was designed like a film camera.
There is one sensor to rule them all. The big one in the middle.
And no not even with a pancake lens will that position of red ring affect WB. It's not near the light path at all.
I do think of this kind of thing. Lots drone lens filters put a colored ring to close to the front of the filter.

Roland Karlsson: Good. Very good.

It is a pity that you can file patents that are unpatentable. That is a waste of everyone's time, money and patience.

Damn that Edison... everyone knew candels were not good so someone would have figured it out. Damn 3M and their stick up notes... That idea is totally obvious. Except it wasn't.
I have co-authored patents, with a patent attorney. Autel was first with the folding drone, they just patented 4 arms that fold out symetrically with landing gear on the ends. DJI foled two under and sits the drone butt on the dirt. AFTER I am sure they saw Autel's patent.

cosinaphile: like patenting the wheel .... its the game corporations play

Except in this case DJI's attorneys are talking a big game. but they also clearly advised DJI to change the propeller design on the Mavic Air 2. You can place the props on the wrong motor if you don't pay attention vs the Autel design which prevents that and which the Mavic emulated.
DJI by changing their design sort of admitted it was a patent violation.

cosinaphile: now if dji can just lighten up on the restrictive software ... that seems to go beyond what is mandated by law

Seems is not the word.
DJI years ago signed with the FAA to be a LAANC service provider. But their entire fly save database for the US is obsolete around airports. The lock places to 200 feet below tree level in my case, when the LAANC altitude is 400 feet. in other cases the new LAANC. But this limit is not self unlockable so It took me 3 months to convince them to unlock my drone to fly at legal levels above my home. Geofencing has a place, but they are year behind in the US, I wonder how it is in other countries.

mr.izo: actually, autel did copy whole mavic 2 series also, if we are at it. but tht patent it realy stupid, now whole world knows it.

The EVO series IS NOT a copy of the Mavic series.
In 2013 THREE years before the first Mavic from DJI. Autel filed a patent that includes folding arms with the motors at the end and land struts at the end of the arms for increased stability. The patent was granted in 2014.
Enter DJI, with a folding drone, but they fold the rear arms under and had the drone sit on its butt, thus it appears learning from Autel, but not violating the patent.
The Evo matches Autel's patent. Which is why DJI doesn't want to open that can of worms.
I would love an EVO II Pro, but I am the happy owner of a Mavic Mini and Mavic Air 2. The Air 2 I credit Skydio and Autel for because DJI took the competitive action Canon didn't for 10 years, and risked cannibalizing it Pro line to compete with new coming tech. So yes the Air 2 will cost them some sales of the Pro level Mavics, but they took my money vs Skydio or Autel getting it. But unlike Canon, DJI is shipping REAL product not rumors and leaks.

Alfred S: What about propeller noise ? The original mavic air was really noisy. How does this compare to that? Or to the mavic 2 pro ?

I saw one youtube with a DB meter that placed it at the same level as the Mavic Mini at a short distance.

kiri: If only I could fly it somewhere...

This is my reading of all the info on the net.
The FAA has total control of the skies and is the final rule. PERIOD.
There are FAA NO FLY zones.
The DJI database is obsolete and far from well synchronized with FAA data, so I suspect it is as bad in other countries.
There are many places near where I live with they limit use where the FAA will Auto Approve a flight in seconds. And oddly a few places where the FAA has a zero altitude limit that the DJI data allows flight in.
As to US laws against drones. In most cases including parks, even national parks they can only limit your right to take off or land on the ground they control, not the flight over the ground. Example if you take off from outside a park you can fly over it and land outside. I would document your flight well as the National Parks Service has a clear record of hunting down youtube photographers who have taken off from in a park and fining them, they are tougher on this than the FAA is on this.

JackM: 48mp mode doesn't seem to offer any more detail, just a bigger image (and file).

Not correct. There are tons of samples on the internet of 12 MP and 48 MP from the Air 2 samples showing the same size of objects and the 48 does have more detail. Keep in mind as with any camera, your real limiting factor is the lens.

dmartin92: Just out of curiosity, is it legal to fly a drone in downtown Grand Rapids, Michigan, near the Blue Bridge, early in the morning ?

I ask the question not to be annoying but just to know: does the sample footage really represent a realistic representation of the things you could do with this drone, and remaining within the parameters of legality ?

You would be surprised where it is legal to fly a drone. Given the shrill nature of some regulators.
In the US FAA has full control of the skies and you can confirm where they consider it legal with the B4ufly app they offer.
Local governments and places like national parks can tell prevent you from landing or taking off from land they control. They can not prevent you from flying over it. The key FAA regulations in a city are related to flying over people and traffic. So when you cross a street you need to make sure it is clear of traffic, then it is legal.
Now if you break other laws like using one to peep in windows that act is illegal, having the drone in the air is not illegal as long as you are following FAA rules.

You can not deactivate geozones!
You can self unlock SOME after checking a number of boxes absolving DJI of liability.
But even then you will find DJI geofencing is obsolete in that it will limit usage in areas and below altitude allowed under LAANC auto approval. And I can speak from directly experience, that DJI will not accepted FAA maps and Proof off LAANC as documentation to unlock to the legal limits. One person did this for me and his manager had him remove the authorization from my account in later days. That means where I live my drone is locked below the height of local trees and at half the altitude the local airport FAA allows.
If you rely on your drone for professional work you should make sure you own a Skydio2 or Autel drone in your kit. Or you may find yourself locked out of LEGAL flight areas.

Vanitas Photo: I will use my "ignorant to the bones" card about 8k here:

Can you tell me why people are so excited about it when the adoption of 4K TVs hasn't been as massive as 1080p TVs (and much less 8k)

I mean you would really need a serious computer and storage rig to edit the footage... Really not being sarcastic nor ironic with my comment, really want to know what's up.

8K content is future protected so will retain value if its commercial. Some great TV shows from the first years of straight to video shooting are almost unwatchable now.
Also you can crop and format video in 8K so get better shots after the fact. But its also a lot of "Something new hype"

K E Hoffman: This brings back fond memories of my youth in the early Micro-computer industry.

When someone was behind and losing sales to another software company, announce version 2! So your current users didn't leave, because you needed them for your upgrade sales revenue models.

"Way better than version 1.5 we just released, that took 2 years.
"Way better than the competitor's current version. That is already pushing the CPU"
"Coming soon! Here's a T-shirt to make it real."

Many of the T-shirts wore out before "Version 2" ever shipped. If it did.
It was called Vaporware! It was an announcement meant to stop the bleeding of customers, while you figured out how to do 32 bit programs on 16 bit CPUS and how to load data twice as fast as current HDs could do it. To match your press release.

No date, no price
No Camera... in 2020 is my guess.
And maybe some spec changes on the final?

Yes it's Canon.
It has no date, because they have no idea when it will all work.
I am sure they are working on it.
But will the announced camera arrive before Sony ships one that matches or beats it?
And since it is loaded with tech they are still new to creating, like IBIS that coordinates with IS lenses, will it work right on release or after 2-3 firmware updates?
This is meant to stop the bleeding of market share. To keep Canon DLSR users where they are, because if they go to mirrorless now. Most won't go Canon
And unlike the micro-computer industry of the 1980's they are building into a smaller and smaller market.
This was a vaporware announcement, some vaporware arrived but when it did it had competition with simular specs.
Wordperfect was king... Missed the move to Windows and worked hard to catch up. Died when it's DOS converter was worse than Microsofts converter.
Giants do fall when they protect brand vs innovate.

Its sort of like watching Canon/Nikon driving head-on towards Sony.
Saying...
"They'll stop."
"I'm sure they will stop."
"Oh, Crap.!!"
Panic Steering!!!!
Suddenly a good driver in a typical situation is in a ditch.
Tactically it's a case-study in getting too cozy with market share in a declining technology to the point of almost missing the next wave.
Remember Altavista Search Engine? How many use Yahoo to find stuff on the web anymore?
How is that IBM PC working for you?
At this point looking at the recent attempts to catch up, Nikon seems to be trying the hardest but is still behind by months or even years. Canon ....

Mateus1: Another test about Z6/7 battery - it seems around 1500-2000 shots per chargé

http://www.rossharvey.com/reviews/nikon-z7-review

CIPA is a benchmark.. Not an estimate of what individuals will find. It tells us the Nikon battery has about half the life of the Sony. It won't tell you the final number you will get from either as each of us use the camera differently.

Link | Posted on Aug 26, 2018 at 20:29 UTC

A lot of criticism comes from people disappointed because they wanted a Sony killer or an instant alternative to Sony. It is neither and it's not its job to be either this generation. Its #1 job is to stop the bleeding of Nikon users to Sony. Thus the undersized but compatible battery. The same with having no interest in adapting other lenses. They are not looking to gain users to a new system. They are looking to guide current Nikon users to their coming system. I suspect the big news will come in 2-3 years when the lens line is larger and Nikon takes Z where E-mount can never go. Medium format. If Canon's mount is a rehash of the EF mount or new but like Sony FF /APC only.. then Nikon will have made a strategic move that will give it a unique place for decades maybe.
That Nikon went from infinitely behind Sony in mirrorless to about 18 months behind, with a few exceptions is pretty good. Welcome Nikon it's nice to have another innovator competing hard in mirrorless.

In reply to:

Royal Majesty: "Overall, the combination of high resolution, expansive dynamic range, compact size, comfortable handling and great 4K video with intuitive and decisive autofocus is hard to dismiss. We're confident in saying that, as of now, the Z 7 is Nikon's most well-rounded camera they've ever produced."

Oh please...

Serious photographers don't care about video on their stills camera and serious videographers don't use stills cameras to shoot video. And serious photographers also don't care about a few ounces and 1/4" size reduction.

What serious photographers care about that are missing on the Z is no-compromises AF performance and no-compromises ergonomics.

Simply being better than Sony is not saying much at all. I mean, seriously, no AF lever next to the lens barrel and dependence on the FTZ adapter for a decade+ is Nikon's most well-rounded camera ever???

Um, no its not. It's a good start, but also a giant letdown because of the glaring totally-avoidable unforgivable blunders.

Sorry that opinion is very 2008. Anyone paying attention can see video people using mirrorless "still" cameras because of size and format. Any many modern photographers are adapting to the needs of their customers to include stills and videos into projects. Those who don't adapt will be getting less work. One device that does both is allowing adaptable photographers to become better at servicing their clients, vs those who are all wrapped up in "Real Photographers..." rules

Najinsky: My dear Sony fanpersons, trolls, shills, or however it is you like to be addressed.

It seems you are unaware that an ILC camera requires 2 elements to become a photo-taking machine. One is the body, the other is a lens.

You repeatedly post on these threads for other cameras saying, just buy a Sony Axxxx with pancake lens.

Did it ever occur to you that many have considered this option and rejected it?

Perhaps you are not well acquainted with actual lens performance, so let me help you out. Please see the graphic on this post:

https://www.dpreview.com/forums/post/60346738

If you are not a graphics kind of person then let me express it in words.

Put a pancake lens on a Sony and you get image recording performance almost on par with an RX100.

Put a pancake on an EOS-M and you get image recording performance approaching that of a midrange DSLR with an 'L' Lens.

When Sony learn how to make compact lenses that perform like good lenses, I may reconsider. But for now, its rejected.

Love the FAKE LENS Data and Myths presented as FACTS .
Lets Try some REAL LENS data. DXO MARK LENS DB
If you get to COUNT Canon Adapted lenses for EOS-M then you get to count them for Sony E-mount too. So you can have any Canon lens you want AND top of the line DR and Image Quality.
But lets talk about lens Say under $600 list price native mount.
Out of the TOP 10 listed on DXO Mark:
Sony Makes 6 Canon Makes 1
Sigma makes 3 that are not available for EOSM but are for E-mount and M3/4

https://www.dxomark.com/lenses/launched-between-1987-and-2017/focal-from-1-to-84/aperture_max-from-0.95-to-45/launch_price-from-0-to-600-usd/lens_zoom-prime-zoom#hideAdvancedOptions=false&viewMode=list&yDataType=global

Let check out NATIVE Mirrorless Sony vs Canon Zooms under $600
There are FOUR listed Sony at #1 Canon #2-#3 and Sony again #4
So keep telling yourself somehow Sony is lagging EOS-M NOT SO...

Mr Canon Fanperson
Why would anyone consider a mirrorless system with so few lenses. Has not Canon taught us... its the Lens count more than anything else you should use to choose camera? Heck if you have lenses you don't even need Dynamic Range anymore.. Right?
BH
E-mount Lenses listed 122
Add in FE and its 246 Total
Canon EOS M 46
clearly a system with so few lenses shouldn't be considered by a REAL SERIOUS PHOTOGRAPHER.. Right? ;)
