On another topic, whilst I am pleased with my 7D so far, has anyone else found that they have accidentally turned the mode dial whilst operating the newly positioned ON/OFF switch? I recently found that I was taking pictures in P instead of AV/TV mode and am pretty sure I turned the dial when using the new switch.
I think I prefered the old switch position.
Yeah I find that I tend to accidentally turn the mode wheel allot on the 7D. I think the mode wheel is also a bit to sensitive and is easily moved. I don't like the position of the new on/off switch, I would have preferred it where it use to be, or Canon should have relocated the switch around the shutter button just like Nikon, and it would also mean you don't need two hands to switch the camera on/off. I liked the switch design and position on the 500D!

So, bronxbombers or skibum5: having read your never-ending bashing of the 7D sensor on your camera, do you plan to dump the 7D?
My copy has a great sensor (little low ISO banding, no mazing, excellent high ISO performance). But the AF sensor on it doesn't work reliably. Have you faced problems in this regard?
Some cameras have great imaging sensor but horrendous AF sensors, while others are just the opposite. Sogh
i don't see where i was bashing it there, i said i hadn't seen video banding myself yet (as for tons of noise at H1 video, that wasn't a bash but a comment, it has somewhat more noise there than the 5D2 but far, far less than any regular video camera)
not sure about keeping it or not, i have to see how the mazing plays out and how the AI Servo does at a top level sporting event (and more real world wildlife results)
so far the one shot af does about the same with center as the 5D2 (somewhat better than 50D) and the outer points work a lot faster and don't hunt as much, both cameras certainly can miss though, semi-regularly with very tricky subjects, not sure if say a D700 or 1D3 is any better, never used those two.
but they both (5D2/7D) seem to do center-point AF somewhat more reliably than my 20D/40D/50D did, which sounds better than your results.

I don't think that digital DR is any worse than that of slide film (and probably a bit better), but it would be nice to have a couple of stops more latitude to accommodate extreme DR conditions.
Are you serious Tom, are you really of the belief digital DR is only 4 stops or a bit better. I'm sorry but I find that beyond belief. The highlight DR is probably 0.5-1 stop better in RAW, but the shadow DR is 2-3 stops better with real detail. Slide would immediately block up at more than 2EV under mid tone, pure black, that's it. With most tests showing digital DR is around 9-11 stops (RAW), and lets take off a few for good measure so we are really getting shadow detail and not noise, and say DR is 7-9 stops depending on model and ISO. It's still not enough, but compared to what I could do with slide, it's vastly superior IMO.
I never found much latitude on slides and that is mostly all I shot unless a client wanted negatives and I shot negatives for PR, weddings and work like that but slide, well I liked them but you had to be spot on or forget it. You can't pull stuff out of the shadows that isn't there and try and get detail from a clear section of film from blown highlights. Then there is the ASA of 100 max for anything decent.
Funny how many people have sold or are selling their 7D's. I think Canon is about to lose a lot more of the market now. The 1D4 better be amazing but as far as I see it, I would rather have a D3s for the FX sensor.
You would have to pry the 7D from my cold dead hands.
The 7D is an excellent camera. Great performance for for the $1699 price.
Yes, I suspect the 1D Mark IV will be an excellent professional level camera.

Great info/rumor Mike, and here I am using my 7D to make some good images. One just won an Editor's Pick for a BIF... , maybe they are crazy, this camera and the photographer both suck.

Check the for sale forums...a lot, like me sell theirs within 24 hrs!
It seems to me that it might take more than 24 hours to determine whether I like a camera or not. It took me a week or so of vigorous testing to determine that my 1D3 had an autofocus problem. And when I had repeatable evidence of that problem, I returned it to the vendor.
My 7D won't be leaving me any time soon - I like the camera.
I really like the 7D ... but, I need to figure this problem out.
I just shot some snapshots of my daughter to test skin tones. Images are ruined with maze effect in skin tones on Capture One v5 (view at 200% to see patterns) ... effect is present in ACR ... effect is NOT visible in DPP. What gives?
Has anyone else noticed this patterned noise in their skin tone conversions from RAW? These images are junk compared to my 5DII.
I'm trying to decide whether to return the 7D, get another copy of the 7D or wait and hope the software is fixed.

If your seeing in ACR and Capture One but not DPP then it is the software.
It has been my experience that most 3rd party Raw converters take at least 6 months of tuning by their respective manufacturers to reverse engineer Canon's files properly.
The RAW data seems to have some serious column gain fluctuation problems, which DPP seems to be correcting for but other converters as yet do not. It is not yet clear whether Canon intends to have this banding, or whether the initial batch of cameras is flawed.
I realize that my post may have been a little confusing. Here is one of my test images. This was shot at ISO 400 right after the sun had set. My daughter was washing her car and stop for a moment to let me take this test shot.
I'm not worried about skin tone, white balance or anything that I can adjust in post processing. But, I am worried about the artifacts in this and all the rest of the images from the shoot. Jim, I understand the tuning and tweaking of the RAW converters, but these files just seem to go way beyond any problems I've seen in the past. AFAIK, the C1 software is production software. ARC, as we know is a beta and complete junk. DPP does not exhibit the problem, but the images seems softer than I would expect (I was wondering if they are processing the files to work around a problem). Anyway, the artifacts just ruin the non-DPP images. I wasn't concerned about ARC until I saw the problems in production C1 software.
The smaller images on the right side are 100% crops from the different conversions.

yeah there have been long threads about this
sadly it does seem i was correct that it is very widespread, i think even far moreso than I had first though actually
even DPP can show hints of it if you really try and even when not really evident it still leaves some extra patterened dots and noise
so far the one very unfortunate thing I have found wrong with the 7D
still not sure if for some reason they made them like this on purpose or their have very, very poor QC with these, a few signs pointing each way
(to repeat it here one post was:
7D mazing, ACR vs. DPP (the way DPP tends toward zipper artifacts seems to help break it up into dotted lines a bit and it also appears to do something or other to smooth out smooth areas of the photos to help hide it, but it still looks odd compared to say from a 20D, so i'm not sure it is really trying to perfectly adjust for different gains before doing demosaic, there is clearly noise lined up along straight lines in a pretty patterned way even with DPP)
and DPR has a number of threads with mazing or maze in the title if you want to search there
it's a shame since so much about the 7D sensor is so much better than the 20D 50D or 40D sensors but look above and see how smooth things are at low ISO in upper midtones with a 20D compared to a 7D.
maybe canon did do this on purpose but i don't know why they would and you can see it show through even with their own DPP in the worst cases, directly, as maze, not sure if they are directly fighting it or applying some NR in smooth areas combined with their zig-zag demosaic that makes it less apparent.
