Substitute Sony with Canon in that search  :P

Also some rotational play is completely normal, happens with all my Canon lenses on my Canon bodies.

Actually, I did that.  There are questions about rotational play which have nothing to do with strength of a lens mount.  Its a tolerance build up on the lens side of the mount, and has nothing to do with the mount on the camera body.
 
Rotational play is not the same issue as a plastic lens mount that is deflecting.  There are no companies that produce replacement mounts for the 100 million or so Canon lenses out there, because they don't need them.  Sure, the mounts do get replaced, but its very infrequent.

Yeah well this is the internet, full of problems blown completely out of proportion and in this case there is a company making money by blowing it out of proportion.

The company selling replacements and making money did not blow it out of proportion, they responded to user demand.  If users do not have a problem, they won't buy one, so they are taking a risk.  The problem came first, then the third party fix. Sony is well known for their refusal to respond to buyer issues. That is something they need to respond to before most Professional Photographers will take them seriously.

...

How do you know? Did you read Roger's posts, specifically what he had to say about Photodiox's video? No offence, but I think I'll trust Lensrentals experiences with renting out "dozens and dozens" of A7 cameras over what I read from that company.

Roger was responding to the posts about loosening the mount screws to simulate the issue.  He said that loosening the screws will always cause it to happen and I agree.
 
I believe that my assessment which says that users who do not have a problem will not buy one is correct, Roger said nothing about that. 
 
I also believe the many posts from owners who saw the issue long before Fotodiox announced their product 5 days ago. Its pretty difficult to announce a product on October 18, and cause camera owners to complain last March.  Some sort of really neat time machine would be needed.

I was just comparing several of the cameras.  It is better than I expected based on earlier raw test images.  This is about as good of a performance as could be expected, and should make buyers very happy.
 
Looking at different areas of the test image seems to result in different results, so I chose the pie chart just below the playing cards.  based on that, and looking at Raw images at ISO 12800... about 1 stop better than the 70D, at least 2/3 stops better than the Sony A6000, and about a full stop better than the Nikon D7100.
 
The 5D MK III is slightly more than 1 stop better, and the 6D about 1 stop better.  As expected the 1D X is over 1-1/2 stops better.
 
The Nikon D610 is 1/3 stop better.

What I care about is that my lens not disconnect from my camera body at the wrong time.  This happened to me with my 5D3 and 500mm f/4 with 1.4x III extender.  I connected the lens to my Black Rapid with my hand wrapped around the foot of the lens in order to stabilize it while walking.  Nevertheless, my 5D3 disconnected with the lens and fell on the concrete (my RRS L-bracket took the hit).  Somehow my 5D3 loosened and rotated off the lens while I was walking along.  I have no clue how it happened.  Anyone who thinks Canon is not prone to mount-related issues is mistaken.

Actually, the big whites have strap attachments, and lens plates are available with attach points as well, its just something to complain about on a slow day.

Your hand or some part of your clothing or the strap depressed the lens release button.  That's a 'mount-related issue' only in the wetware sense (i.e. you).  I speak from experience, in my case it was the belt loop of my jeans when carrying the 5DII with 70-200 II after mounting the 2xII.  The TC altered the balance of the rig and I didn't change the position of the 1" clamp connecting the BR strap to the lens foot.  FWIW, my camera was fine although when I checked AFMA I found the values for all lenses had shifted ~10 units negative.

That's a issue that has been around for Bayonet mounts since they were first invented.  Push the button or pull a lever, twist the lens, and it comes off.  Threaded lenses were better in that respect, a lot of people preferred the breech lock system, but the same thing could happen, just not quite as easily.

I'd think that a secondary safety lock might be useful for those who are carrying the camera on a type of strap that lets that button get pressed unknowingly.  The standard Canon neck strap cause the accidental release, it merely puts my neck and back into agony.

Maybe someone could convince Fotodiox to make something like that, or a kick starter project.  I'd have to have funding to buy one each of all the Canon DSLR's and lenses in order to test it out  thoroughly.  I guess I'd need to try it with all the carry straps as well.

I've a couple of ideas to do it.

There's a much simpler way to handle that problem: glue a security eyelet to the side of each lens, attach a short strap with a carabiner, and when you attach the lens, clip the carabiner to your camera strap.  That way, even if it detaches, the lens won't fall very far.

I wonder if China will ban sales of the Sony cameras like they did Nikon with the D600?  Japan also banned sales of the Nikon D700 due to its unsafe battery.

It probably depends on Sony's response to the issue.

Each new release of a Apple OS breaks Canon Software as well as lots of printer drivers.  Its best to wait until either Apple does a fix, or Canon releases a fix.  I've seen posts that say 3.1 works, but 3.0 which was released a few months ago does not.

I've seen a thousand posts asking why Canon did not have a XX mm camera lens in their lineup.  They have far more lens models than other manufacturers, but its not likely that they will have every possible lens focal length and aperture.
 
I found my 400mm f/5.6 to be too long to be a practical carry around lens and to fit in my camera bag.  A 500mm lens would be even longer.  Reducing the aperture size reduces the diameter, but not the length.   How many people would pay $4,000 for such a lens?  Canon, like it or not, prices lenses at much higher levels than the third party manufacturers.
 
A zoom lens is more practical to carry around, since they normally only extend to their full length when zoomed out.

Yet another thing that makes me scratch my head on how some people get / keep jobs.

First and Foremost - Again my biggest gripe with reviews - Understanding the target audience - who is the camera designed / aimed for and does it meet those needs.

To me at least, the 7D MK II is aimed at sports photographers and wildlife - this means a little reach (crop) decent ISO (It is APS-C), Sick Autofocus

1)  Her first gripe is the AF Mode lever on the back - WHAT??? I used Expanded AF Area a lot as well, but am constantly switching zones and modes when shooting sports.  It is about control and sometimes I want the focus on a subject in a specific area and am creatively using DOF to the picture.   I cannot understand how a sports photographer does not want more control, especially in a sport like football where a player may break in front of you and take away the focus you want.

To me at least, this lever is a GOD SEND and in a place that will not bother me.  If Anything, I think the placement is genius.

2)  Her major gripe - no Audio tagging of images.  How many cameras do this?  1Dx, D3?  A nice feature but seriously

3)  Love the Duplicity - Crop sensor a plus for reach - crop sensor a negative for image feel.  Who is the target audience?  Seriously.  People by crop sensors (at least my opinion) for a price break, both in the sensors appear cheaper and they gain more reaches with their lenses.  Comparing the 7D to the 1Dx again... I would take the 1Dx in a heartbeat.

4)  Lack of analysis on the AF.  Then again, not surprised given she only shoots in one mode and does not switch.  The 7D MK II seems to be up their with the 1Dx in terms of AF features and capabilities.  The fact that limited tracking analysis was done as well as little digging into the modes immediately shows her naivety.

And seriously.  If you time some of the holiday sales right, you could wind up with a Sigma 150-600 and a 7D MK II for the price a little more than a 5D MKIII

That is in essence a 240-960 with Crazy AF performance.

One thing I would be interested in is if Sigma will be upgrading their TeleConverters as well.  A 1.4X or 2X with this combo will likely be MF only, but that is then a 480 - 1920mm

To try and compare the 7D MK II to a 1Dx is folly. 

Then again, if you want to bring dollars into the equation and spend $7500 of lenses and bodies, which will give you more?

 
I'd say that someone else other than her is Na├»ve.  The 7D MK II is targeted at amateurs and enthusiasts who do not depend on a camera for their income.  I'm in that category, if my camera stopped working, and I lost a game making play, it would only matter to me.
 
She was given a preproduction model to try out several weeks ago, so she did.  Canon does not give out pre-production cameras to photographers who do not know how to use them.
 
She is a professional who uses cameras at the highest level.  Show us some of your photos that are published so you can confirm your qualifications to criticize.

My 5D MK III allows for setting of Standard Time as well as setting Daylight Savings Time.  Some places do not recognize it, some change by 30 minutes, so setting it properly should eliminate the issue.

You may also find some Black Friday discounts coming up.  They have to compete for the buyers dollar.
 
Adorama has 1 new pro 8 Elite left for $150 on ebay with free shipping, so you would save $50 on the upgrade.

Her analysis is exactly what I expected of the camera, so, of course, I tend to believe it. 
 
This is not a camera intended for photographers to use in professional level sports.  That's not bad, its just what it is.  Certainly, it can be used for professional sports, but lacks the features to fit into a workflow that makes use of voice recording, as in her example, where different people develop and edit the images, and need to be able to title them accurately.
 
She mentioned that it still had a lot of noise at high ISO's, but is better than the original 7D.  I've seen plenty of test shots by now that confirm that.  The APS-C sensor might gain 1/2+ stop over the original 7D, but there are no miracles or violations of the laws of physics.
 
Overall, for the price, its going to be a great camera and very popular for enthusiasts and for wildlife, but it is not a substitute for a D1X, and not advertised as such.  I'd have no problem buying one, except that extreme low light is what I do most, and even a FF sensor struggles there.  I don't expect a new FF sensor to be much better in low light, but some of the other areas are overdue for a big improvement.

Canon General / Re: new 70d, wrong manual, no plastic wrap

Your description sounds like a gray market camera.  Did you buy it from a authorized Canon Dealer in France, or from a online seller who might not be authorized, and selling gray units, which may have no warranty, depending on the local Canon office.

+1...In addition to AF speed, I like the idea of having EVF for afternoon shooting.

I still like my 5D III + 40pancake. Still, it's nice to have a pocketable camera for an afternoon walk sometimes.

Agreed, even a evf is better than none at all, and the built-in evf of the RXIII is very appealing.  I really miss one on my G1X MK II, but have no plans to buy the evf as of yet.
