EOS Bodies / Re: *UPDATE* Canon Rebel T4i/650D on June 8 [CR3]
« on: June 08, 2012, 06:48:47 PM »

I think its a new sensor because the pixel masking necessary for phase-detect pixels has to be added underneath the microlensing, as the microlens is an important factor in making FPPD-AF work. That would require some degree of reengineering...even if it is relatively minor. There may also be additional activate/read wiring to read out only the phase-detect pixels for AF before activating the full sensor for an image readout.

Well, the sensor surely had to be tweaked to accommodate the hybrid AF and maybe other minor enhancements.

You surely cannot just plug-in a 7D sensor in the 650D and expect it to have hybrid AF.

But the underlying sensor architecture and technology appear to be the same.
Hence, the sensor will perform the same way (more or less) as the 600D/60D/7D sensors.

Or, as I put it in another post:
It's a brand new sensor ... with the same performance as the old one ;).

Aye. And those pixels remain functional for standard imaging as well. Despite the masking, they do not actually remove pixels from the normal bayer image output...its just that since a few hundred thousand, maybe a million pixels are used for FPPD-AF, vs tens of millions for the total image, the IQ impact is non-existent.

So, except for the 'sunglasses', these pixels are no different than the other pixels on the sensor.

But isn't this what I said in the first place - that the hybrid AF has no bearing on the sensor. ;);).

But they don’t need to be special pixels or anything.

Sorry, but that is completely false.

Aah. So, we have certain pixels on the sensor wearing 'sunglasses', figuratively speaking.
This of course makes them totally different from the other pixels. Got it.

after searching 650D review, every article I've found says NEW Sensor, but they must be considering it new since it includes the phase detection AF.

I just looked at the ISO-series of samples on DPreview.

The 650D definitely has a brand new sensor ... with the exact same performance as the one on the 600D, 60D, and 7D.

But -- I'm just not  yet convinced that this 18MP "new" sensor is actually new. 

I sincerely hope you're wrong :P

If you think that the 5DIII has a "new" sensor compared to the 5DII, then yes, the 650D's sensor is also "new".

i apreciate your sensor tech knowladge and would like to read your opinion if it is a new sensor or a recikled on from 600d?
Can they add a sensor layer for the focusing sistem to a eksisting design or do thej need to design a ne on?

sorry for my bad English.

It's a tweaked/recycled version of Canon’s current 18mp sensor.

The hybrid AF has no bearing on the sensor.
For hybrid AF, certain pixels just need to be read out by the AF processor as well (in addition to the image processor).
But they don’t need to be special pixels or anything.

As for the higher ISO setting:
This is achieved with tweaks to the read-out logic and also by the Digic 5 processor.

EOS Bodies / Re: What will the 650d sensor be like?
« on: June 07, 2012, 05:05:25 PM »
I didn't mean to put down the 60D in any way.

Just saying that Canon made the 650D identical in specs to the 60D (sans the top LCD).
So, no more product differentiation between the two - a clear sign that the 60D days are numbered.
And that a higher specs 70D is on the way.

I think the only upgrades this year will be digic 5 and the AF and lens. Next year would get the 70d sensor.

+1.

The sensor will be the same one that's currently used in the 60D and 600D.
Maybe tweaked a little.

The 650D will still have some image quality improvements, though - coming from the Digic 5+ processor and Canon's new JPEG engine.
Maybe half a stop cleaner ISO.

In addition to the update AF, the 650D is also getting a pentaprism viewfinder.
Thus, the only difference between the 650D and the 60D is now the top LCD screen.

In other words, the 60D is basically dead. Long live the 70D ;).

EOS Bodies / Re: New Full Frame Camera in Testing [CR1]

I guess "sooner than you think" in fact means that Canon has found yet another new way to release a high-price product -  sooner than people would have feared after the 1dx and 5d3.

LOL ;).

This would leave Nikon to care for folks in the below $2000 segment...

Which is where the majority of buyers are, of course.

I was just thinking the other day:
The market leader in any industry is never the one with the premium pricing.
With its recent pricing policy, Canon is obviously trying to become a premium vendor.
So, have they decided to lose their market leadership position ???.

Aah, it seems to me that somebody has been daydreaming again ;).

So, Canon is going to compete with the $3K D800 ... with a $10K camera.

I wonder how this is going to work ???.
The D800 plus the trinity of Nikon f/1.4G primes (24, 35, and 85) will come cheaper than $10K.

Let us daydream for while ;) ;).

nice :D 

Sure thing ;).

Seriously, though, people on this thread want a 1DIV ... for a third of the price of the 1DIV.
That's classic!

Also seriously, I have no idea what Canon will do with the 7DII.

The word on the street is that the 5DII will be discontinued by the end of the year.
If Canon is planning to keep the 5DIII price high after the 5DII is discontinued, then it must be planning an advanced camera to fill-in the gap between the Rebels/60D and the super-expensive 5DIII.

But by the end of the year, Nikon will have the D600 - an entry level FF camera for $2K.
This leaves Canon little room in terms of specs & price for the advanced camera that will sit below the 5DIII in the lineup. 

If Canon is planning to charge around $2K for this camera, then it's not impossible that this will be the 7DII ... with a FF sensor.
Otherwise, the 7D will just be discontinued and the 70D, priced at $1500 max, will take its place.
In that case the 5DIII price will also have to be reduced to be more competitive with the D600/D800 combo.

Finally, it's not impossible that Canon will pull a "5DIII" and release a 7DII ... with a crop sensor and priced at around $2K.
I know for sure what I'll be doing in this case  8).

I still believe canon will pull something out of its sleeve. they need an ACE IN THE HOLE, and i believe the 7D II may be that ace if it has the following specs. APS-H - 14-18MP

Hope dies last!

Let us daydream for while ;) ;).

The 7DII will be out in the next 6-9 months ... with an 1.6x sensor
So, now is the time to daydream.

I seems to me that there are several anti Canon/pro Nikon threads - and it is always the same group of suspects whinging and whining

And of course there are always the Canon apologists.
No matter what Canon does (and how overpriced it is), it's always good.

I never understood the mentality of an apologist, btw.
What is it that drives an individual to defend the profit-driven decisions/actions of a profit-driven corporation ??? ?

Me? I just hate overpaying and like to get good deals when paying with my money.
No brand loyalty from me if I feel that a corporation is trying to milk me.

With the Sony sensors and the d800 release price, it seems Nikon wants to attack Canon and not just go along with them, and a budget ff body might be the way to throw down the gauntlet.

I think that Nikon and Canon are just targeting different crowds with their new offerings.

Canon seems to be targeting pros and the video/film crowd with the 5DIII. Hence the high price:
Pros will pay anyway and the video/film crowd supposedly has deep pockets. 

Nikon, on the other hand, has pros and photo-enthusiasts in mind with the D800.
And the rumored D600 will obviously be targeted squarely at enthusiasts.
Thus, the lower prices - especially for the rumored D600.

The question is, what happens if the video/film crowd doesn't line up to buy the 5DIII as they did for the 5DII?

255
This is why the D800 is such a game-changer. It establishes a totally new price-structure for higher-end DSLRs. 

+1000

Quote
New structure:
* Nikon D4/Canon 1D X - flagship specialist journalism/sports camera, max speed, limited resolution - USD/€ 6,000
* Nikon D800 - max. resolution, fully featured, except speed: USD/€ 2,900
* Nikon D600 - second-tier FF-model, less resolutuon, features scaled back: USD/€ 1,500-1,700  2,000

Canon has failed to adequately repond to this and will undoubtedly pay the price in market share.

My thoughts exactly - except that the D600 will be USD/€ 2,000.

I also think that Canon is failing to respond adequately to the current market trends .. for now.
They will have to, though.

Canon won't get much help from the film/video crowd this time around.
So, they will have no option but to drop the 5DIII price in order to make it attractive to photo-enthusiasts.

Patience, padawan, patience  8).
