I have brand loyalty...one reason I bought an S95 is that I already had a 7D and a 5DII. That's what Canon had in mind, right?!?

As for moonlighting, "This new Rebel camera is a great choice - just came out and has LOTS of megapixels. You should also get this great second lens with a BIG zoom.  You'll need these Promaster protection filters, has 'pro' in the name 'cuz they're what the pros use. Oh, and you really need to get the great extended warranty we offer - it covers everything, no fine print, honest!"

Well, let me see here.

I have a 20D, and my longest lens (aside from my telescope) is my 70-200/2.8L IS Mark I with stacked 1.4x teleconverters.  That combo performs very well at it's optical peak of f/9.

Just a couple of days ago, B&H has the 70-200/2.8L IS Mark II for $1,974.  I thought very seriously about jumping on it, primarily for it's ability to perform well with stacked 1.4x and 2x teleconverters on an 18MP 1.6-crop sensor.  I didn't, however, because no Canon body with that sensor could AF with that combination.

My goal is basically 2x more real resolving power than I have now, with the same handholdability and while retaining fast AF (basically, near diffraction-limited with AF).  I have 8.2MP and 400mm, so 16.4MP and 560mm would do it, or 32.8MP and 400mm would do it (assuming sufficient optical quality in both cases).  Well, with the loss of f/8 AF sensors on the 1D line, it seems like the only hope is for a ton of pixel density.  24MP and 400mm would get me about 70% more real resolution than I have now, and maybe that would be enough to make me spend all those thousands of dollars, maybe not, by 18MP and 400mm wasn't, even with the $400 off a couple of days ago.

So, yes, bring on the pixel density, and bring on the flexible video crop options - they're handy with astrophotography and in other special cases.

I know that the specs aren't out yet, but I figured the new kiss x6 would at least have the digic 5 processor in it.  But what I wanted to ask, if I was looking for improved ISO performance, would it be worth the upgrade from a kiss x4 to the x5?  Or should I just wait and get the 70D when it comes out? 

Side note, I hope that they at least put two mics on the new kiss coming out, does wonders for audio fidelity.

650d, likely the moment that I'll change my 400d. I have been waiting for digic 5. better iso and video is almost certain, (H)DR would be nice.
I hope for finally a better af (micro adjust?) then the 30d/400d, better viewfinder and no more or even less (than 18) MP :P

I don't think we'll ever see AMFA on a Rebel/xxxD body.  They excluded that feature from the 60D intentionally, and so I doub;t they'll add it back to the xxD line, either - it will remain a feature of xD bodies only, the 50D being the sole exception.

Can't have been enough positive feedback from customers about it (if they even discovered/used it.)

Big Mega pixel counts for those that don't know any better, and bigger pixel sites for those that do.

Will that allow some kind of natural product split where i have to "downgrade" MP to upgrade dynamic range.

Wouldn't it be ironic if the 700D had 24 mpix and the 7D2 had 12 mpix.

Higher-end cam: fewer mpix, less noise, better colors.

Thanks for the info.  Any word on whether these cameras will have phase detection af and if they will match the new Sony's in video? 

Holding off on purchasing, but will pull the trigger once Canon makes this info known.

It doesn't seem plausible to me that Canon would release a 24mp APS-C sensor. According to Canon themselves, their BEST L-series lenses are only capable of resolving about 45mp of detail in a Full-Frame image circle. The current generation of Canon's 18mp APS-C sensors have exactly the same density as a 46.7mp full frame sensor, which would mean that a 24mp APS-C sensor would far outresolve any lens Canon has on the market right now, and probably for several years to come at least.

I think it would be far more beneficial to Canon to work on the IQ of their current 18mp APS-C sensors than to try and boost megapixels any farther. The only area where more megapixels makes sense is in larger sensors, and given they have dropped APS-H (or seemingly so), that means full-frame sensors.

<strong>The next Rebel

</strong>I received some early specs about the coming update to the T3i. We’re told to expect it before CP+ in February.</p>
<p>The camera will probably be a new 24mp APS-C sensor and run a DIGIC 5 processor. The DIGIC 5+ won’t be used.</p>
<p>Expect some standard upgrades in ISO performance, HD movie modes and some creative control updates. The final spec list is not yet finalized.</p>
<p>It was mentioned that Canon may keep the new sensor for a 60D upgrade, with the next Rebel sticking at 18mp.</p>

Is "the next Rebel" the next entry-class Rebel after the T4i, i.e. a T4?  Because, obviously, the T4i could be "the next Rebel" we are likely to see.  This has been confusing me ever since the post went up.

The same Rebel, I think.  In other words, the T4i will probably have a new 24MP sensor, but Canon may use that new 24MP sensor in the 70D and keep the T4i at 18MP.  At least, that's how I read it.

According to Canon themselves, their BEST L-series lenses are only capable of resolving about 45mp of detail in a Full-Frame image circle.

If Canon ever said that, whoever said it was about as clueless as clueless can get.  A 1.4x TC is about the same as doubling pixel count.  Do you seriously believe that a 400/2.8 can only support a single 1.4x teleconverter on a 5D II?  If so, look at this:

http://forums.dpreview.com/forums/read.asp?forum=1029&message=37493247

That's 4x worth of TCs on a 400/2.8 on a 7D!  That's the equivalent of 737MP on a full-frame sensor.

I routinely use a 2x on my old 70-200/2.8 on a 20D - the equivalent of 32MP on 1.6-crop or 84MP on full-frame - and get pixel-sharp shots (which shows I'm still undersampling).  The new 70-200 is much better than the old one, and has been shown to support stacked 2x and 1.4x on the 7D (the equivalent of 144MP on 1.6-crop or 369MP on full-frame).  The best primes are better.
