You guys will probably think I'm weird, but depending on how improved the 70D sensor turns out, I'm thinking about selling my 6D and going to two or three crop bodies. (Downgrading from FF to crop? zomg!)

I love the sensor in the 6D, but it looks like everything else about the 70D is shaping up to be better than it's bigger FF brother. Faster flash sync, better autofocus, higher fps, articulated screen, built-in flash... I can't think of anything on the 6D that is better besides the sensor (don't use GPS). Switching back to APS-C also means cheaper bodies and lenses, which means I can afford more bodies and lenses! (f/1.8 Sigma zoom anybody?)

I would trade some sensor performance for a bit of everything else. It looks like the 70D is going to offer a lot of everything else.

Just don't underestimate the IQ value of those big pixels. You won't get that kind of IQ in a crop body. Even if Canon has made some improvements, and I certainly hope they have (otherwise the 70D IQ will be worse than the 7D IQ), it is unlikely that their 20.2mp APS-C sensor will beat the 6D in terms of IQ. That holds true especially if they have not moved to a new fabrication process...if they stuck with 500nm, then the photodiode area for these pixels will be REALLY SMALL. It would have to be a BSI design in order to make it perform better than the 7D with 500nm transistors (which isn't out of the realm of possibility...just still too early to make the decision to sell a 6D and jump the FF ship just yet, IMO.)

That is exactly where my question earlier in this thread pointed at: does "new sensor" also apply to new tech? If things remain as described here, we are still far off from improved high ISO IQ. So the crucial changes will have to be here. As I have a 5D3 I am very interested how Canon will progress in this during the 5D3's "product cycle". Although it is an excellent camera, I am still keen to see better high ISOs. And what I can guess based on the tech centered threads here a lot of it depends on sensor tech AND processing power via DIGIC upgrades.

Better HIGH ISO's aren't the problem, at least not in your 5D3.

@bdunbar: of course you are right! as you know me from other threads, I am always dreaming of better high ISOs, but I am absolutely happy for the moment with anything what my 5D3 delievers! It's a great cam. So, once Canon turns its next page in sensor tech as mentioned above, it will get much more exciting as I am looking forward to an overnext 5D body... :D

Yes, Sir!  8) Today I was at a wedding. A weddingtog was shooting an 1Dx with battery grip, looks cool.

Hard to shoot a 1D X without the battery grip.  I suppose a hacksaw could be used, but I won't vouch for functionality after removal...   :o

@neuro: As I do only know the 1Dx by the posts about it and never held one in my hand, is there an extra battery power unit (battery grip) by design? that's great of course and necessary. I feel like a fool by mentioning it the way I did it... :-[

The grip is integrated - part of the body, all one piece.  The 1-series bodies are similar in size to other bodies with an accessory battery grip. The 1-series also use a larger, more powerful battery.

I've been looking for a replacement for my T1i for some time.  I wanted to wait and see what the 70D offered.  Right now my budget (based on some assumptions) will allow for either the 6D, 5DMII or a 70D.

I'm going to wait and see what the more educated say about real world results on the 70D.  Particularly, I'm interested in low light (noise) handling.  Of course I'm interested in dipping my toes into the FF world, but that option will trigger the sale of my EF-S 17-55 and the acquisition of something like a 24-70 or the 24-105 (more realistic).   I can't imagine that both the 70D or the 6D aren't worlds better with AF than my current camera.

It's good to see the 70D look like a step forward instead of the sidestep that the T5i looks like.  It sure makes next year's rebel and the 7D upgrade seem a whole lot more interesting.

I am surprised that nobody so far has asked the big question about the 70D..... Does the mode dial go all the way around?

Don't laugh! That was one of the best things about moving from t2i -> 60D. It was pretty easy to inadvertently move the t2i dial when taking it in/out of a camera bag.

I hadn't thought about the possibility they WOULDN'T have that, but I agree, the photo looks like it has the center release button on the mode dial.

Hi all, I'm new here, It's my first post.

Welcome to the forum :-)

With the 70D, I would like the return of the double fontions on the buttons of the top, near the LCD.

Won't happen, Canon nowadays reserves the double button layout for the "pro" bodies 7d/5d while for us cheap Joe Sixpacks with a 70d/6d it's much too confusing :-p

Although it is an excellent camera, I am still keen to see better high ISOs. And what I can guess based on the tech centered threads here a lot of it depends on sensor tech AND processing power via DIGIC upgrades.

Well, new sensor is new tech regardless. It had to be redesigned to achieve the extra 2.2mp, so it IS new technology. New technology does not inherently always mean new fabrication process...which is what a move to 180nm or 90nm would be. I believe the sensor is "new tech", and I believe it will perform well. The big question is will it be competitive...i.e. performing as well as the top competitor chips. If Canon has not moved to a new fabrication process, and has instead chosen to stay with 500nm, then I do not believe this sensor will perform well relative to the competition. It may be only marginally better than the 7D, assuming the weaker CFA of the 1DX/5DIII is applied.

I don't think Canon can remain competitive in the long term if they continue to rely on an ancient fabrication process. I think the 70D will be EXTREMELY telling in that respect, and could provide hints as to the 7D II and "Big Megapixel" camera due next year. If Canon does stick with a 500nm process, then I'll get a 5D III (as it is definitely better than my 7D at this point) and be done with it. If they finally move to 180nm and Cu interconnects, then I'll wait and see what they do with the 7D II.

Let's get (even more) speculative. The leaflet claims HDR and "continuous images" for a time-lapse effect. Can we assume we'll be able to take more than 3-bracketed pictures, or that we'll finally have a software intervalometer? (other than ML, when/if it's ported)
