Mike

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.

Why would you sell it on buy and sell vs. sending it back to the vendor for refund?

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.

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.

UCSB,

process the RAW files with Canon's Digital Photo Professional and see if you get the same skin tones. I suspect you will not.

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

among various threads on FM try starting about halfway down here:
http://www.fredmiranda.com/forum/topic/809801/120

(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)

This image is copyrighted by the owner

and 20D ACR for reference:

all are ISO100
)

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.

It's the infamous Canon QC at work here. While I am not plaqued by mazing, banding or other sensor artifact issues, I have an even more serious problem: horrible AF even in centre spot AF. Leaves me fuming.

Its just my own observations. Just check the for sale forums, I think there are 3 on there right now. Plus a couple over at POTN. And that is what is available right now...plus they aren't selling as fast as they were when I sold mine. People are having to drop their price in order to unload these things.

The noise (or mazing) is terrible at low ISO's on a LOT of these cameras. While DPP does handle the files better than LR3 or CR Beta, the artifacts are still there. For me, thats not good since DPP is made to work with these cameras.

Are you absolutely sure that you don't having the mazing effect? What did you do to test for it? I was initially pretty sure that my camera was OK, but after some more careful looking and learning how to see it, I found that it does, just like I believe every other 7D that has been analyzed by Emil. As skibum5 has commented, there's no way at this point of knowing if this is designed in or not or whether it will be properly tamed in ACR or CR1. I really like the camera, but noise in skies at ISO 100 is not cool.

Well if the price difference between new and used is not a lot why buy used ?. With Microsoft cashback or ebay, it's way "cheaper" buying new.

I just want to go on the record and say, I NEVER had these issues when I shot Nikon! Nikon comes out with a new camera every year, I have owned the D200, D300, D3 & D700 and I bought them all when they were almost new and NONE of them had issues that we are experiencing with Canon. 1D Mark III and its focusing issue, 5D and the mirror falling out 5D Mark II black dots and now the 7D.

Nikon has no issues ? C'mon.....Not sure why you are using Canon now ?...and on the same token people have never had problem with their Canon equipments.

Obviously you are just a fan-boy and don't know when to admit that Canon hasn't created a problem free camera in years! I shoot Canon because it is less expensive, they have a better selection of primes and I am one of the few that prefer the AF of Canon.

I don't recall a single issue with the D300, D3 or D700...not a single issue. And reports from the D3x and D3s show the same pattern. For Canon, lets go back to 2005 when they created the 5D & 30D. The 30D seems like a solid camera only had one new one malfunction and the mirror locked up in the first 80 frames. But that was just a fluke.

The 5D has had a major issue with the mirror falling out and not til they stopped making the 5D did Canon decide to do a free fix for owners.

Then they came out with the 1D/1Ds Mark III. Don't get me started on that camera. It took them three years to the get the AF right. Haven't heard much about the 40D or 50D except maybe the IQ or noise not being as good as previous models but I guess we can say that the 40D & 50D weren't really bad cameras. I mean, I have a 40D and no real complaints there.

5D Mark II - black dots and I believe there was something else too, just can't remember when I had mine.

7D...where do I begin!

For me, I have owned a ton of cameras, 10D, 20D, 30D, 40D, 1D Mark III, 5D, 5D Mark II and D100, D200, D300, D3, D700. I have had multiple copies of each except the D3/D700, which I only owned one of. I had one D300 that had some dead pixels, other than that, NEVER had an issue with Nikon. As for Canon. 10D metering went out, 30D mirror locked up, 5D Mark II would not recognize lens after using for 20 mins (display f0 in the top lcd) and a 1D Mark III that gave me an error on my first shoot with it (self cleaning sensor malfunction).

Its all personal experience, believe me, I am a huge fan of Canon but I also know when to say that something is really wrong with them lately.
