Canon EOS 7D Mark II Spec List [CR2]

[Plamen]

you tell me that this forum  is the best place , but no one have answerered my question,  is this a wish list or is it a reality when it comes to Canons sensors? 24Mp at a APS size and what  is the signal noise ratio with current technology and  the dynamic range compared to others

See this.

How harmful would it be for them to pay a small team of photo nerds to surf the web all day and find out what buyers want?

Because people posting in forums are not necessarily buyers, or at least there is hardly any connection between internet opinion and sales, the latest example is the underwhelming but popular 6d.

What happens if you ask buyers about what they want you can as well file for bankruptcy right away like when Homer's brother let him design a car: http://simpsons.wikia.com/wiki/The_Homer

And another example highlighted above.  Only a small number of people in Canon know whether the 6d is "popular" as far as meeting expected sales figures.  And a similar small number know whether the "underwhelming" view of the 6D is just from crazed internet forums or actually the view of the camera buying public at large.

For example, I think the 60D was under-speced, with the deletion of MFA a big mistake.  I also think the 6D should have had an AF system at least as good as the 60D.  But unless someone at Canon shows unusual candor, we'll never know if they agree with these points, or if they even acknowledge that these issues affected sales of the cameras.

Tests have shown that even the best APS-C lenses are limited to around 20 megapixels of resolution,

Point me to those tests and I'll show you why they're wrong.

[Plamen]

what is it that I should look after?

The QE figures determine the shot noise per unit area. A sensor with 42% QE, for example will have 1/2 stop better noise performance than one with 30%, at base ISO, at least. (Ratio of 2 is one stop). This is valid for comparisons within the same format.

Then there is data for the read noise, this determines the deep shadow noise.

I know Bob,he is a friend of mine , who has this site.

I read some of his posts elsewhere, he is a smart and funny guy.

[Plamen]

yes I know what QE is , and ?

You asked about comparisons to others. They are a lot of them there. The newest Canon FF sensors are comparable to the Nikon ones in terms of QE. The current (a bit old already) crop sensors are at 40% or so, so they lag a bit behind. What I expect is to see a new crop sensor with QE around 55% or so. This would be about 1/2 stop better than the current 7D.

I have no idea what to expect about the read noise.

Since it is obvious we don't have that data (I guess even Canon doesn't have a representative overview on the worldwide opinion in different buyer segments on the 6d) I was talking from my personal perspective - and according to the initial reactions to the 6d (mine included) there shouldn't be anyone out there buying it, but obviously a lot of people are nevertheless (me included :-)).

For example, I think the 60D was under-speced, with the deletion of MFA a big mistake.

I also though so but stood corrected - removing afma from the 60d was a very smart move by Canon, lots of people bought the more expensive 7d.

I'd like to see these tests as well, Radiating. The Nikon D3200 is already a 24mp APS-C, and it produces some amazing quality, and its pixels are in the 3 micron range. Small form factor sensors have pixels under 2 microns now.

If one wants to talk about finite limits on pixel size, I'd offer around 800nm, or 0.8µm. Any smaller than that, and you are going to start clipping frequencies of visible light (starting in the deep reds)...but we are a LONG way off from sub-micron pixels in larger form factor sensors.

Where did you get this rumor from - CR :-> ? I think the decisive Canon people are in Japan and a small circle of execs (like the CEO in a recent interview) and maybe some tech people, and I would be very surprised if any information from places like this would reach them - most likely they rely on their internal marketing studies and some direct feedback from cps professionals and beta testers.

How harmful would it be for them to pay a small team of photo nerds to surf the web all day and find out what buyers want?
(Heck, I'd do it for free if they let me try some prototypes every now and then.)

Very harmful.

The data would not be simply useless, it would be misleading garbage.

Market research is a science. Canon has decades of hard data based on its sales figures. In addition, everyone who fills out a warranty card goes into a data base that Canon can mine for additional information. They scour competitors annual reports and sales figures, just as the competitors scour theirs.

The data is supplemented with surveys that adhere to strict standards to assure that they are polling a representative sample of customers. Those surveys are no doubt conducted on every continent to study trends in each region. They also likely use focus groups of key customer subsets to flesh out the data. They use field testers to try products out in the real world and give them feedback.

A basic rule of any polling is that you never, never use subjects that self-select. They are notoriously unreliable and not representative of the larger universe. Just one tiny example shows how fruitless it would be: there is zero ability to match up the data on this website with actual buying patterns. There is nothing that could assure Canon that the whining, trolling and fantasizing that goes on on internet forums has any relationship whatsoever to sales.

At most, they may employ robots to search the internet for key words and associations. The best you can hope for, is that if Canon finds a spike in the internet on some word string, like: "5DIII, Weak Focus, Low Light " they might investigate it further to see if there is a trend or problem developing.

But, it is crazy to think Canon or any other manufacturer is going to waste valuable resources trolling internet forums.

It does make sense, indeed.
Thanks for the great answer!

Hey Canon, I want a 1DXs - a 45mp full frame camera with 1DX performance.  Will happily pay up to $1500.  Don't forget to make it EF-S compatable in crop sensor mode.

And how's that Eos-Me going with built in EVF and zippy AF?  I assume we've got some new lenses coming out soon?

PS - Where can I send my invoice for market research work?

I guess I'm learning it the hard way... 

[jrista]

I have read this thread with interest, I have use  Canon cameras  the  10 last years
My own feelings is that this is some kind of  a wish list.
Where can I find some hard  facts about  what is going on with Canon and  theirs new sensor technology or are the using the same old technology but improved as good as it get?

CanonRumors is the best place, really. Anything with a CR2 is pretty good information. The only time you will get better information is when CR starts posting CR3 rated rumors, which are, for all intents and purposes, fact.

Thanks a lot

If I had to guess where the information came from, I would say that, assuming an Aug. 2013 release date is legit, it is one of probably several potential specs, based off of a prototype someone has been using in the field. Whether these are the specs that actually end up in the retail version, no one can say...not until someone actually has a legit retail version in their hands or breaks and NDA.

I wouldn't necessarily say this is just a wish list. If it was CR0/1, definitely a wish list, but since it is a CR2, it could be legitimate information based on pre-release spec sheets, a closed-room session a known source had with canon reps, information based on a prototype version out in the field (potentially second-hand, so the information could be a bit more sketchy if that's the case), etc.

I wouldn't go around stating these specifications as fact, but I wouldn't simply discount them off-hand either. It's a rumor, and its a pretty decent one...the best we have at the moment.

As for the sensor's ISO range, noise quality, dynamic range, etc....no real solid rumors on that yet, so no one can really say. If the sensor is fabricated on Canon's past 500nm process, I wouldn't get my hopes up all that much. You can only push a process so far before you hit a brick wall. I am not really sure what value a 24mp APS-C sensor would have on a 500nm process...the circuitry would consume so much die space relative to the photodiode itself, I can't imagine such a sensor would perform very well in any context. With a 180nm process, that cuts the transistor size down to nearly 1/3rd, leaving you with far more room to dedicate to the photodiode, making APS-C sensors with pixels smaller than 4 microns more realistic.

The question is how the internal Canon decision hierarchy is - it'd be interesting to know, but of course no one will tell. I guess the final say on the gear to be produced is either made by accounting (estimated profit, i.e. mainly production cost flavored with some marketing thoughts) and/or by the top execs if it's a strategic decision.

The recent interview about the 7d2 might let us hope that Canon tries to make a big splash this time to make up for the recent lack of user's enthusiasm, so the 7d2 might really come out with a lot of features at a "reasonable"  price - but then again it might just have been a decoy to gain time because Canon is behind in the sensor race.

[mdrewpix]

If true, is it me or is the Canon camera lineup getting confused? Used to be that upgrades were real upgrades, and you'd upgrade to get better features for a similar price as you originally paid. Now you're getting more, but paying more, and the difference between the bodies is getting smaller. 

Not quite.

Have a look at Thom Hogan's article entitled 'The Last Camera Syndrome'. We are getting there, if not there already.

I'm talking about me personally - I'd love to upgrade, I like to get the latest features and have the money to do it, but Canon just isn't giving me a reason to do it. A high megapixel body would do it though.

On "The Last Camera" yes DSLR's are past the point where you need to continually upgrade I believe. The 5DIII has great metering, great autofocus, great IQ etc. Even the 5DII with it's poor autofocus system is good enough to last me another five years easy. This is why I think Canon needs some big features like new sensor tech to lure us back.

A while back a Canon rep said "users need better pixels, not more pixels". Seems like Nikon is taking them up on that one. And besides they didn't really give us better pixels.

Sorry, but that kind of thinking is just foolish. How much more detail do you really need? And I said need, not want. We already have cameras that out-perfom the hallowed slide films of yore. And this constant foolishness with the Nikon vs Canon debate has to stop. If you can't shoot decent pictures with what's already available then the problem is not with which camera you're using.

I really can't say how Canon decides what products to bring to market. I imagine it is a rather complex process with far too many "moving parts". I work at a very large, established company that develops online educational platforms. From the outside things look very simple and cohesive, but decision making processes are extremely complex, usually involve hundreds of people, and take a very long time. We have an 80-step process that must be followed to patent anything, that spans at least 7 departments.

Given how large and established Canon is...I'd imagine their decision making processes are fairly similar, at least on the complexity front. Although them being a Japanese company, things are probably more orderly and refined (something the Japanese excel at, where as American companies tend to get mired too deeply into political infighting, empire building, petty squabbling, etc.)
