It sounds like he is asking highly biased questions and will ignore whatever answers he gets because his mind is already made up....

No time wasted, the rough specs have been out for 6 months, only those hoping for something that defies the laws of physics will be disappointed.

Except for no WiFi or touchscreen, it is what I expected... plus a few more AF points as a bonus.

The purpose of an add is to sell product.... not piss people off to the point that they will never do business with that company.... the advertisers need to re-consider what they are doing....

"The switch from FD to EF in 1987 was clearly for the better."


Of course the switch to EF was the right decision, it didn't help "US" with thousands of dollars worth of gear though. Also you both seem to have missed my point, which was, Canon will do what they believe is best and give us the cameras we actually need, rather than profess to wanting, and they have been proven to get it right enough of the time to make the sales they do.

The question would be couldn't they have done the same thing and somehow preserved the FD mount?
Or was it a sales gimmick to force people to buy new gear. Remember we're talking 1987, in technology terms digital photography for the masses was a long way off.


They had to make a decision.... control the lens digitally... or control it with analog signals.

Unlike older systems where every function had it's own pin and there were even some systems where the lens was driven from a motor inside the camera body, the EF mount was simplicity redefined. Power, ground, data in, and data out, and a clocking signal.

They really didn't have the option of a hybrid system as that would have done nothing well. Keep in mind that digital sensors were emerging then and the writing was on the wall.... the film DSLR was on the way out and there was going to be a massive upheaval in the industry. Lenses were already at the point where it made more sense to control them digitally so looking at the future, Canon really didn't have much of a choice.

BTW, I got my first digital camera in 1986....

I agree withe AvTvM. WiFi is an inexcusable omission. Not only is it a matter of tethering but also  I like reviewing jpegs for example with no fuss or muss in a busy restaurant on my phone & sharing quickly & easily.  Once that would be a luxury but now its a comon feature :( available in cameras that cost less than $99.00. This cries out to me canon is negligent & or intends to rip me off.

Next is touch screen. Now don't get me wrong we want & need our existing hard buttons but in many cases option of tapping screen is a huge huge time saver. Such as reviewing pics, live view focus & even menus. Fast  :o navigating is important right?

Kinda like buying a brand new high end car & being told keyless entry & amfm radio doesn't come standard........
Grrrrrrrr canon >:( >:(  just grrrrrrrr!

EOS Bodies / Re: How does the reveal of the final 7D2 specs make you feel?
« on: September 14, 2014, 11:35:35 AM »
The one spec that no one seems to be mentioning much is the dual Digic 6 processors. Now I'm no technical guru so maybe extra processing power doesn't make much of a difference to anything but if the 7D Mk2 is such a small step forward as some are suggesting why does it need/have more processing power than any other camera in the Canon range (with the possible exception of the 1DX with it's 3rd processor)?
The extra processing power will allow you to produce better in-camera jpgs, will allow the higher frame rates for stills and video, and will also allow you to run far more complex AF and tracking algorithms...and that's the part that I am really anxious to see what they have done...

What's pathetic is the inflated sense of entitlement some of you lot have - "how dare Canon not make me my perfect camera..."
It's infantile - Canon isn't in the business of keeping you happy.

Well, if Canon is not in the business of keeping US happ ... representing pretty much a cross-section of their best, most loyal and longstanding clients who typically have shelled out anywhere from a couple 1000 bucks to a couple 10.000 on Canon products ... THEN Canon has no business. AS far as I am concerned.

And YES, we are fully ENTITLED to demand better products from Canon ... as we are entitled towards any other supplier of gear who fails to deliver products that are not as good as as they could be and that are not at least as good (!) in every which way as competitor's products and "technical state of the art" is.

We are even more entitled to demand this from the self-proclaimed global leader in imaging technology who has claimed on numerous occasions to bring us nothing less than "the future of photography".

Tell that to the many thousands of pros back in the '80's when they swapped from FD to EF mounts. Canon will do what it believes is in the best interests of its shareholders in the mid to long term, coincidentally they very often know better than us what we actually need.

The switch from FD to EF in 1987 was clearly for the better. Not only for Canon shareholders but for any photographer willing to buy their new products and enjoy the advantages of autofocus and alls sorts of beenfits associated with electron communication between lens and camera ... in the best implementation on the entire market. Yes, Canon could also have kept muddling on ... like Nikon did with their long obsolete F-mount and mechanical aprture coupling, but that was and is a very sub-optimal scenario for their clients and one of the reasons why many of us chose and choose Canon over Nikon and other screwdriver-AF companies.

Also, those clients who did not see the benefits of AF for their work had no problem to just hold on to their FD lenses and cameras. After all, those were analogue SLRs and not DSLRs were you need to upgrade to get improvements in image quality. Mechanical Film SLRs were little more than film holders with a shutter and viewfinder in them and progress between mechanical model generations was fairly limited ... real progress was only achieved once that lens mount was changed and electrified.

Even I - being a tough critic of Canon and certainly no fanboy - applaud them for the foresight that went into the EF mount. It has held up during the major changeover from analogue film cameras to digital DSLRs and is only now approaching the end of its lifecycle, as we soon will switch-over to native mirrorless lenses with shorter flange distance. The transitions will not be as painful, because this time round it is easy to privide simple extension tube adapters to keep the EF-glass working for as long as we are willing to accept the inconveniences of such an adpater solution. :-)

Canon knew that the FD mount was dead. The world was going digital and they designed a new lens mount that was capable of surviving well into the future. Watch what happens when Canon goes mirrorless in it's high end bodies.... you will end up with the exact same mount....

Just small incremental upgrades.  Not much to show for all the years of development if you ask me.  I'll skip the mark II, thank you.

Since I skipped the 30D, 40D, 50D, 60D and 7D, this looks like a huge upgrade to me over the 20D I shot with (very successfully) all day today.

I'm shooting with a 60D and it looks like a huge upgrade :)

My biggest question is, should I get a 70D or a 7DII?  Some advantages for each.  I'll wait for the announcement and first tests on the sensor of the 7DII before I make a decision.

Interestingly, I was considering between 70D & 6D versus 7DII & 5DIII.  I like my 20D and 5D because they basically have the same user interface.  But, for what I use it for, the 6D would actually probably be better than the 5DIII (WiFi would help at times, GPS would certainly help to keep the clock accurate, the low-light focusing point is probably more useful for me than the 5DIII's advanced super-fast focusing).  So my wife basically told me to suck it up and get the 7DII and 6D, and just learn to handle the UI differences.  Still thinking about that, but she probably has a point.
At the moment, we don't have a clue if Canon has addressed the noise problem or not.... I give it 50/50 odds. Rumours say a new sensor, yet at the same size as the 70D. It is possible that the 70D sensor was the first "kick at the cat" for an APS-C sensor with finer lithography and that the 7D2 builds on that sensor and adds in cleaner A/D... It would certainly make sense, but it is just a guess... We should find out in a week or so.

EOS Bodies / Re: A Surprise Cinema EOS Announcement for Photokina? [CR1]
« on: September 13, 2014, 08:09:22 PM »
I am fairly certain that there won't be a big Cinema EOS Announcement for Photokina.
IBC is going on right now(where Sony announced the FS7) and it is really the most likely to place for such an announcement.
The FS7 is interesting movie from Sony. If I had already invested in a F5/F55, then I would feel slightly pissed.
Nothing stops them from announcing it in two different places.....

EOS Bodies / Re: Digic 7 Development
« on: September 13, 2014, 11:10:43 AM »
This new processor is the key to high MP cameras.  Doubling the resolution will require 1.414 times the processing power.  The current Digic 6 will drop the 1Dx to 8FPS.  The Digic 7 is going to be a dual Digic 6 in one package which will allow 4x the processing power for high MP, high frame rate bodies.

Canon normally has 4 versions of their Digic Processors, the + version for the high end bodies.  I thought that the upcoming 7D will be the first to use the Digic 6+.  Why would they put a Digic 6 meant for low end DSLR's in a 1DX?  When the successor comes along, it will have two Digic 6+ processors, which will be appearing in cameras starting with the 7D MK II.

Do you have some facts?  Reference?.  Test Results? 

I'm not sure what to think of the comments, and your information about the make up of the Digic 7.

Canon uses ARM processors that are custom packaged for them and giving a Digic number.  Nikon, Sony, ...everyone does the same thing.

The issue is to get processing power with a low power usage.  This means that the fastest processors may not be used due to power consumption.
A lot depends on the architecture. You typically need computing power for short bursts, so a common trick is to use variable clock rates and to shut off cores under periods of low need. With the slower clock the devices use less power, and shutting down cores does the same. For example, perhaps the various cameras with dual digic processors normally run on one chip and only enable the second when you press the shutter....

Exactly, but not all ARM devices have the same power efficiency.  As new more efficient devices appear, they will be the candidates.

The Cortex versions seem to be the low power champions currently, but reducing the current 28nm process can reduce power / performance.

I notices a announcement that a new snapdragon processor will use the ARM Cortex A7's.  Its a lot like digic, it uses ARM processors plus more custom processors and firmware to accomplish a specialized task.  I'm not sure how the power usage compares with a DSLR, but I expect it consumes a lot of power.

agreed!
I would suspect that it is lower power for some tasks and higher power for others. What the net effect is would be anyone's guess, but since it is developed for cell phones, my bet would be lower in power overall.

I don't know what the video/still ratios are on smartphones, but I suspect that the video demands are far higher than on a DSLR... after all, video runs all the time, even when taking a still picture. I don't know, I/m just guessing.
