Canon EOS Rebel T4i/650D Specs [CR2.5]

Yay! No More Megapixels

Sony is keeping a 16 mp sensor in their new Nex-F3 and A37. Perhaps both have determined that the marketing benefit of ever-higher megapixels has reached the point of diminishing returns.

I think this has more to do with economics than it does anything else.

so out with the swivel LCD and in with the touch screen? replacing one gimmick by another

Somebody better tell Apple that their iPad is one big touch screen gimmick.  You may not have noticed, but the world is going touch screen, including Windows 8.  My Sony camcorder from 2004 has a swivel LCD with a touch screen.  This is not new technology and it is far more intuitive than trying to navigate around with buttons which is like using your keyboard when your mouse dies on your computer.

As far as the swivel being a gimmick, I use a T3i at work to photograph industrial equipment and I use one for personal use. I find the gimmick rather useful, enough so that I specifically chose the T3i over the T2i for that reason.  You may not use it all the time, but when you are taking photos high or low or if the tripod is backed into a corner where you can't get behind the camera, the swivel is very useful.  Adding the touch screen will add to this because when the camera is in a position that makes the swivel convenient, it means the back of the camera is at an odd angle that is hard to operate where the screen would be facing the operator.

Touch screens are fine - except for those with big fingers and poor sighted. My father takes pictures with his P&S happily as he is longsighted (it has optical viewfinder) , but has memorized the position and meaning of the buttons.

and big noses....

I'm sorry but I've never seen an explanation of the benefit of Cross Type AF points could someone quickly explain?

Try focussing on venetian blinds w/o cross type af and it'll explain itsself... it's about pattern detection.

Yay! No More Megapixels

We should do a lottery - my bet it'll be the same 18mp sensor, and this would be no reason to cheer. When they introduce new tech, it'll in more expensive bodies, and then they'll at least do 19-20mp just for marketing reasons.

I agree 1000% this year they offer the cross type auto focus with Digic 5 as an improvement in a few months when 7D2 is announced with new sensor etc etc making it king of the APC hill they can then trickle down that sensor in another year or so like they did with T3i ETC.....    call the T4i this current generation of apc-s sensor's swan song.

What is the advantage of crosstype AF points?

One of the reasons I'm not using the Kindle Fire (was given to me as a gift) is the touch screen. As example, it appears whomever designed the device didn't think of people with fingers as big as mine, so I can't type a short URL without fixing it at least three times.

As of Apple, the success of their products is no indication of quality, e.g. the brick with tiny B&W screen sold as a portable computer is a good example. If Apple put it's logo on it, the fanboys would buy petrified dog S___ as a premium air freshener.

Continuous AF in LiveView & Video Recording in 650D is nice.
Now Canon just need to put it into the hopefully coming 7D II together with a new 18MP sensor with better ISO performance,  60fps 1080p movie, CF AND SD with possibility to use Eye-Fi SD, weather sealing.
And this needs off cause one or two Digic %+ processors.
And  possibility to decide the name on the pictures (IMG_9999 is not enough, would like IMG_2011_xxxx or IMG_xxxxxx)
If Canon is going to put in Touch screen, it shoul be OLED, otherwise you can’t read it in the sun shine.
The 7D II must also inherits the autofocus from the 5D III

18MP again?. Boring.

18MP again?. Boring.

But sufficient for many uses, esp those of xxxD series owners.

Just that they have it doesn't say how it performs, it's Canon's first try, but maybe the processing power of the digic5 makes it possible.

Indeed, and Canon just wouldn't put a sensor into the 650d that can outgun the more expensive aps-c bodies. That's why they called it "650d", there will be a 70d with a sensor upgrade and *then* they'll put into a "700d".

[Lee Jay]

I hope they up the pixel count on the 70D/7DII, partly for the lower noise benefits (despite popular belief, smaller pixels yield lower noise overall images with the same detail), and partly for the greater resolving power when focal length limited.

[whatta]

well, I would not mind even less than 18 MP, but would certainly prefer a new sensor (not the same as in 7d, 550d, 600d, 60d).

if the rumor is becoming true, it seems finally the AF sys is coming down again after the 30d (into 400d); 40d AF in the 650d then? so the 70d should get the one from the 7d.. and digic 5 of course.

what about the 240fps video in the S100? why is it not in the 5D3 and not rumored for 650d?

I would be interested in integrated wifi though (to share quickly and easily).

oh yes, and a bigger viewfinder would be always welcome.

18MP again?. Boring.

I think this summarizes the reason why the MP wars are waged in the consumer crop body space.  Generally, people perceive it is not a better camera unless this number goes up.  for that reason yes it would be boring to enter an updated 18mp camera into a MP war.  My hope is that they introduce a  new sensor and bump up the MPs by some small amount, for example, 21MP (15%) just to maintain excitment, and keep the MP wars where they belong -- in the Rebels.  Higher MPs in such a Rebel, along with a small (or even zero) improvement in ISO/DR, will leave room for further improvments in the same technology life cycle for the 7D2 -- for example, game changing ISO/DR, and 10 fps with Dual Digic 5 and a larger frame buffer.

Not if the increase in pixels is overcompensated by the increase in nose, then even say 24mp downsized to the current 18mp will look worse. And what's more mp good for if the dynamic range drops? If you want that, it's time to get a high-mp mobile phone... I would like a moderate increase in mp, too, say 22-24, but not no matter what.

It isn't clear if the 650d will have sensitive af points for f2.8+ like in the 7d & 60d...

Compare 36 MP D800 to 12 MP D700. There was a massive 2 stop increase in dynamic range and a massive improvement in high ISO performance as well.

It isn't clear if the 650d will have sensitive af points for f2.8+ like in the 7d & 60d...

The current 600D already has the extra-precise AF point in the center for f/2.8 and faster lenses.
