They cleared the CMOS on the 1d3 to get 10fps. That's 2 frames faster.

I'm worried for Canon, not myself. I don't own a 7D so I don't care. :lol:

The 1D3's 10fps doesn't nullify my point, because they're different sensors. Like I said in my previous post, if the 7D's CMOS is already clearing optimally, how is a firmware going to help? A recall of the 7D for this reason would be the worst possible kind, because it's related to the sensor, the most expensive part of the camera.

Slow it down. It already does when shooting sequences in low light.

ouch...
I have taken similar shots.
I wonder what specific events bring this about?
OK, fast fps...but anything else?

Electronic shutter problem? Looks like an easy fix.

The Canon description of the problem says it does not occur in "properly exposed shots" but may become visible if "levels" are adjusted...

All I know is that I haven't seen it on mine and that there's an awful lot of other people's shots that don't show it either. I want Canon to fix it but for now it seems like a non-issue for me personally.

I'm guessing an issue with a buffer not being cleared correctly.

Or maybe Canon had intended to finally include the ability to do a multi-exposure shot and didn't fully delete the functions before releasing to the public?

Maybe it they did not control everything so tightly in testing this kind of thing might be found out prior to release.

Also, I continually try to talk myself out of thought that there are lots of "bad copies" out there, and I know that what some think is a bad lens is actually operator error, but items like this dont help.

Is it really a sensor issue or the digic processor issue with how they are mapping sensor readings into memory to create the files during a burst? Like others said, let's give Canon time, I am about 95% sure it could be fixed with firmware.

There is no defense for this. It shouldn't be there at all, period, in my humble opinion.

It's official in the US too:

Service Notice: EOS 7D: Residual Image in Picture

Thank you for using Canon products.

We have confirmed that in certain camera settings and shooting conditions, the phenomenon described below may occur in images captured by the EOS 7D Digital SLR camera.

Canon is currently investigating and analyzing the cause of this phenomenon, and we are planning to release a firmware update to address this issue.

Once the support measures have been established, we will post the relevant information on our Web site.

We offer our most sincere apologies to customers using this product who have been inconvenienced by this issue. Going forward, we will spare no effort in our quality management to make sure our customers can use our products with confidence. We hope our efforts will earn your understanding.

Phenomenon
In images captured by continuous shooting, and under certain conditions, barely noticeable traces of the immediately preceding frame may be visible. This phenomenon is not noticeable in an image with optimal exposure. The phenomenon may become more noticeable if a retouching process such as level compensation is applied to emphasize the image.

Affected Product
EOS 7D Digital SLR

Got my 7D last week. Went back and checked my 1st 1000 shots (all sports) and could not find any "ghosting" in them.

In my experience as a software engineer, IF they can reproduce the problem, they WILL be able to fix it easily. Kudos to Canon for coming out and admitting they have a problem.
