I think it may be a new canon mirrorless announcement :)
and I think it may be a 7d2 that shoots 12fps, has 1dIV level weather sealing, 82pt-AF, APS-H with 5d3-like ISO noise, for $1800.  ::)

I get the sense that you are new to the details of photography, so here are a few basic points.

Your prior camera, the 600D, was a crop-sensor camera using the EF-S mount.  This sensor was smaller than the full-frame sensor in the 5D series cameras (and the 6D and 1D), using the EF mount.  So, the 18mm wide end of your EF-S zoom lens on the 600D is actually equivalent to a 28mm EF lens on a full-frame camera.   

There are a number of EF lenses that cover this range.  For primes, you could look at any of the 28mm lenses.  If you are shooting handheld from a ladder, you might consider the new 28mm f/2.8 IS lens, with image stablization that will help with any blur from handholding.  There is also a 20mm f/2.8 lens with a wider field of view that is inexpensive.  For zooms, there is a 17-40 f/4 and a 16-35 f/2.8 that would probably work as well.  Zooms generally have smaller apertures, so they require more light, but that should not be a problem with a 5d mark 3 or 6D (although the 5d mark 2 it may be).  For wider apertures (1.8, 1.4, 1.2), note that the field of view, or the area in focus, is very narrow.  For more detail, you want smaller apertures (larger numbers, like 5.6, 8, 11, etc). 

The TS-E lenses are manual focus, and would require you use a tripod and spend lots of time with them.  The "stitching" of images is also more time spent on the computer afterwards.  It does not sound like that is what you are looking for. 

However, changing lenses is not hard or time consuming, and you could also get a 100mm f/2.8 macro lens (the version with the IS if you are shooting handheld) to take your detail shots right after you take your wide shots.  Or you could get the EF-S 60mm macro lens and put it on your old 600D for your macro shots, but note that this lens will not work on your new full frame 5D.

Also, you should look into the 6D camera.  Its built-in wifi might be useful in your working environment, and the autofocus will be plenty for photographing stationary carpets.  The images should look just about as good as the 5d Mark 3, and maybe even better than the 5d mark 2.  (This is the kind of thing that people on the internet argue about a lot, though).

I hope this helps.

Pulling two little details out of this for emphasis: 17-40 would be significantly wider on FF than 18mm was on the 600d. So it might be wider than you need, but might also mean not having to go as high up the ladder, which I'd think would be nice. Plus, it's got great optics, is very reasonably priced (available as a refurb from canon for $571 right now), etc etc. I'd say that would be a great lens choice... Second, the 6d is also available pretty inexpensively right now, and has very good IQ, and is definitely worth considering. You'll notice a huge increase in image quality with that combo over what you were using previously.

I wanted to get the IS II but it looks like budget will be an issue.   :'(  If I get this lens, this is the only lens I would be able to get and I wont be able to afford a wide lens before the season starts.  I'll go ahead and get the f/2.8 non IS version and get it before the end of May.  I can shoot video with the wide lens or use a monopod or tripod, if I have the 70-200mm attached.  Then I try to get a wide lens by August.  I could really use the $900-$1000 extra dollars towards another lens.

Maybe next year, I can get the IS II.

keep an eye on the refurbs- the 70-200 2.8 non-IS had been in stock for a while, apparently now is sold out, but it may come back before May. Great way to stretch your budget a little further. 10-22 and 17-55 IS are both in stock if you want to get a wide lens now...

Just like WiFi was first on the 1DX :)

Just to nitpick for the sake of nitpicking (I agree with what you are saying in general): Wifi is hardly new technology anymore... ::)

Also, since this thread has already deteriorated like dozens before it, I guess I'll share this observation here. Canon may be a market leader in terms of sales, profit, whatever, but in at least one market, they're WAY behind. I was in Washington, DC this week for a conference at a hotel right across from the national zoo. I would go for a walk in the zoo on lunch break, because the weather was nice and it was outdoors. I saw dozens of small Nikon SLRs, and in 3 days of walking around, only two other Canon SLRs: one CPS member with a 1Dx+300 2.8 II, and a 7D+70-200 IS II. Not that this was conclusive in any way, it was just an unexpected observation I made...

Oh well basically the same sensor again.
Yeah but we knew that... They don't want to undermine the 7d2.

I fully expect the 70D will be a refreshed 7D: "new" sensor with on-chip AF, built on the same process. Better sealing than 60D, somewhere in the 6-8fps range, and decent (maybe 7D) AF. Given that 7Ds now go for 1300ish new, I'd think that 7d specs would put the 70d right where they want it in the lineup. That sets them up well for a 7d2 to be a better camera, that they can charge accordingly for.

Thanks all for the replies!

Lets see if I can answer all these questions:
-I do not use ML; not that crazy a question, I've considered it, but no, I'm using factory firmware.
-Longer version of the anecdote: she said she was manual focusing because the camera wasn't focusing, but she thought it was fine at the beginning. Looking at her shots, she nailed some running dogs, so I'm pretty sure it was fine when she got it, and died during that day.
-I have not really tested any of the batteries, since I usually recharge at the end of a day of shooting. But I have fired off 2k frames in one day of ski racing, and not had to change battery. Unfortunately don't remember which battery that was... Statistically speaking, twice as likely to be a third-party one, right? ;)
-battery terminals look clean to me
-both third party batteries AF right down to one bar.
-this OEM battery is ~5months old, can't have more than half a dozen load-cycles. Came with my 7d when I got it, refurb. Makes me less likely to bother returning it... If it is a faulty battery it seems more worth my time to recycle it and get another $15 wasabi power one... They've been great in my gopro for 2 years, and so far so good in this context as well.

Edit: because I got it from canon direct, I'm inclined to think its genuine. Now, it may be refurbed and already have a ton of load cycles, but I think it was in retail packaging...

EOS Bodies - For Stills / Batteries and AF

Question for all of the collective wisdom here:

The other day, I let my sister borrow my 7d. She's used to my dad's 60D, and probably getting a rebel of her own, so I wasn't too concerned about her messing anything up. When she gave it back to me, it wasn't AFing- with any lens, regular or live view, nothing. When I MFd in one-shot mode, I got a focus recognition beep. Checked all the connectors, they were all clean. Finally, I looked at a pin diagram, and seeing that a pin provides 6v for the lens AF motor (something I logically knew, that was just the inspiration) I popped in a fresh battery. Suddenly, AF worked again!

My questions:
Has anyone ever observed behavior, where a battery shows 2 bars of remaining charge on the top LCD, and the camera takes shots, but doesn't have power to AF?
The battery I had in was OEM. I swapped in a Wasabi power LP-E6 clone- any OEM/3rd party compatibility issues? I'm inclined to think no, since the OEM was the one that caused the problem.
Should I do anything? At this point, this is purely an exercise in intellectual curiosity- that wasabi power LP-E6 has now taken 1,000 shots without issue, so I'm curious more than concerned.

Thanks!
Brian

I agree with what's been said. I subscribe personally, but I also use dreamweaver for a bunch of websites, illustrator for graphics (a lot of which I use for work presentations), and I like to play with new toys, so I'm teaching myself after effects. I doubt I'd feel I was getting my money's worth if I only used PS and LR.

Try AF expansion. Avoid single point AF in extremely low light and Its worked good for me.
Hopefully upcoming firmware fixes all of this, though...

Are you trying to compensate for something????
sounds like buyer's remorse to me...  ::)

This neuro, is why I'm taking handfuls of antacid tablets right now...

If you let the trolls give you indigestion, you're going to need something stronger than an antacid tablet around here.  :P

Dare I ask your medication of choice? As a neuroanatomist you must have access to something stronger... ;-)

Regarding fps:

10fps on 7D2 or for that matter 70D is just plain silly...it ain't gonna happen.

I lean toward Canon keeping the same 8 fps, may be 1 more up to 9fps to throw the fanboys a bone. Canon will be thinking about their bottom line, not the unrealistic "needs" of fanboys who want the whole shop for little money.

Something tells me the shutter mechanism is not the most expensive part to produce. If it was, that would be a different story. But they've already done the R&D: the 1dx shutter mechanism can move a full-frame mirror at 12fps, rated for 400,000 cycles. You really think an APS-C mirror, at 10fps, with a 150,000 cycle rating is that unrealistic? Sounds like a piece of cake to me... I'm not saying they will put 10fps in it, just that I don't see why it's so far fetched. Especially when you say they'd do 9 to "throw the fanboys a bone". If it's that easy to add 1 fps, why not two?

It is not about the value, wheather they already have the technology, or how easy it is to just put it in... it is about how a company "grades" and markets its products at different price-points and "ascribes" a persumed value.... note, I purposefully did not say "actual" value. Some of persumed value has to do with the inherent value of the product, but what differentiates a successful company from a mediocre one is how they mold and stratify and add to this inherent value.

While it is true that no amount of smart marketing or PR will be able to market a grandma as a supermodel...ie, she has a certain street value that is inherent...what a good marketing team can do is take a young, average looking girl, and depending on their ability, get her enough clients. While a much better looking model, with a different marketing team, is sitting at home near the phone waiting for a call that ain't coming.

As unfair as it sounds, fps is fps...weather it is on a APS-C or FF...logical reasonings have little effect on the basic marketing priorities. How the fps are stratified between their 1 series, mid series, and lower-end models will be a an easy call for Canon.   

So they will continue to follow their marketing strategy that is working based on revenues...not what is logical.

so, in a nutshell, you think they'd do 9 but not 10, just because double-digits are reserved for the 1 series?

I really do hate marketing teams...

An APS-C shutter is smaller and lighter than a FF shutter.... and you have less distance to move it. Shutter mechanics is NOT the limiting factor.
This was the basis of my point- the discussion now seems to be product differentiation vs. halo-APS-C-cam, which was my misunderstanding of what RS2021 was trying to say.

I doubt we'll see the 7D AF in the xxD anytime soon.

I don't see why not... It's a very good system, but they could absolutely improve it for the 7D2. I think putting 7D AF in a 70D would be a huge step up from the 60D AF, and putting the 1Dx/5D3 AF in the 7D2- even if they remove some points so it's 48 (or whatever) instead of 61- would also be a huge step up. Granted, we'd be charged accordingly, but it seems to fit the bill for who these cameras are marketed to- enthusiast (xxD) and pro APS-C (7D)

It seems to me that if you believe the 7DII sensor will be cut from the same wafer as the rumored "big megapixel" camera, then I'd say 21 MP is too low.

21x1.6=33.6, and I would be very surprised if the FF biggie came in at only 33.6 MP, less than the D800's 36 MP.

Of course this assumes the two camera sensors would be sharing the same sensor design, but that seems to be what a lot of people are thinking around here. So.... :-\ :-\ :-\

1.6 is the crop factor, not the difference in area of the sensor. I think 1.6 comes from the diagonal, if I'm right?
Not feeling up to doing much math this morning, but that's what google is for, right? I've heard people say FF has a 1 1/3 stop advantage in light gathering, which I assume means more than twice the area (really 2 ^ 1.3333 times the area), which means 52.9mp.

I do like the 21mp number better than 24 for APS-C... I personally have no problem with 18, but I'd be OK with 21. I'd certainly take 21+less noise over 24+more... I'm not trying to print 48" wide.

Splitting hairs a bit aren't you? Personally, I'd like exactly 20.85MP ;)  The difference in file size between 21MP and 24MP is pretty small (though not the files themselves!).  It sounds like you are falling for the "fewer megapixels equals lower noise" myth.

OK, I see your point, and it does sound like that. I'm more in the camp of "I highly doubt canon will give us 24 mp AND much-reduced noise, because that would be too much camera and they can milk us for more money by not putting them in the same camera".
