I have run a few "tests" on these images and I think the magenta areas are all blown highlights (as suggested by Rook. I used the removal tools to eliminate the magenta to see what was underneath, and in every case the underlying area was over exposed. There are very few signs of CA in other parts of the images.

When you get the camera I would suggest a reset, remove any filters from the lens, then few shots in a shady area. Do not use any scene modes, use base ISO, auto WB or cloudy. Follow that with bright area, and if possible with a change of lens.

Compare those shots with deliberate over exposure shots.

If the magenta recurs, then possibly either the sensor or the processor is on the blink.

Also check the lens mount - unlikely but any looseness?

Many thanks all who have contributed your inputs. @Searcher and @ Rook2C4 your inputs are most appreciative. While I have not been able to get the "physical camera" as yet from her, I was able to open the RAW Data from one of the images in Photoshop. IMG_6318.jpg (Woman with Rebel shirt) - re-uploaded with "StoreOriginal" flag selected.
I am no expert by any means and only just barely understand what I am looking at; however judging by what I see and her comments of using "AUTO" mode, my guess is it may be as you say, an issue with the sensor. If one of you finds something else that I am not seeing, many thanks in advance for your pointing it out (so that I too may learn).
If indeed it is a "sensor" issue, do you guys recommend a "fix" or would she be better off with replacement (in your humble opinions of course).
Again many thanks to all!! and many blessings. While not an active "commentator" on the forums until just now, I have enjoyed the many threads and comments I have read over the past year or so since finding the site. ~erik

thanks tradio... I was trying to determine if anyone has seen this occur as a result of a "physical defect" with the camera as they are straight from the camera. She is going to bring me the camera to look at (you know how friends think just because you can fix computers and such at work, you must be able to build their new home - LOL). She is a sweet older lady so I told her I'd take a look and not knowing a whole lot, figured I'd start with the basic question to guide me in the direction(s) to look for answers.
Thanks for your initial insights and please feel free to let me know if you know of any "causes" that might be specific to a setting or malfunction that requires professional repair.
Cheers, many thanks and appreciations, ~erik

A friend of mine has a Cannon Rebel XTI and recently started getting these weird magenta blowouts in her images. Has anyone ever experienced this or know what causes it?
