Yep you’re right this is not an issue. The shot is a clean, crisp, staged office shot. Using a tiny bit of window light and soft boxes. It was more of a studio set-up, I’m hardly pushing the camera to the brink, woo 200 ASA, 60th @ F11. I’m baffled by this problem and even more surprised by Canons response.

cpi: I recall your issue with images taken under indoor fluorescent light, but at 1/60th, it shouldn’t be an issue.

Has anyone had this problem???? On viewing an image more closely only at 50% I noticed a random block of brown color against what was a plain cream wall. I’ve been on the internet all day trying to find this problem. Having no joy I’ve just called Canon, who for some reason don’t even want to see the image I’ve taken, they are going to try to recreate the fault by using my settings (200ASA,60th, F11, like that’s really pushing it) and will get back to me. Feels like a brush off, anyone had this problem?

Noel Carboni of ProDigital Software has made an PS action that will eliminate the Black Spots until Canon gets it sorted.

Anyone else having the auto-off problem? My unit turns off and does not turn back on unless I remove the batteries.

Daniel, I think it would have been fair to ask for permission before you use any of my photos. I don’t even see credits anywhere. My original photos have a clear watermark showing my copyright information. You used a crop out of these photos.

I was able to reproduce the problem with mine, even with those settings turned off. You can see some samples here:

anyone have another example with a pic that isn’t horrible? looked on the FM forums (haven’t had time to go through the rest), that sample is pretty miserable. would be interested if it’s the overexposure, just high ISO, or combo of the 2… thinking about upgrading here, but might wait till tax refund time (then again, availability may dictate that anyway, can’t seem to find anyone with one in stock)

James,
Are you referring to blooming edges??? Take a look again, none of Chromatic Aberration (lens induced) and Purple Fringing (much-sensor induced) ever suffer “Black” pixel Chromatic distortion.

This is absolutely in consequential!!! Every digital camera ever made using Bayer pattern sensors suffers from some type of one to two pixel wide chromatic distortion at the boundary of blown highlights. This is because the Bayer filters use combinations of three red-green-blue receptors to interpolate color, and the three colors all saturate at slightly different light intensities. It physics!! If you want to eliminate this entirely, you’ll have to find a new sensor technology.

Keepin’ an eye out for this however not a major issue since I’m not a pixel-peeper.

Had mine for a couple of days now and love it.
