1. There is a special mode where you can adjust anything (ie not accidentally changed elementary settings, if you accidentally press a key.)
2. Important also the IS mode - for the elderly usually mandatory.
3. She had only 2 buttons "learn": the power button and the shutter button (- harder than you might think).
4. Also the viewfinder is a must, because otherwise there is a permanent eyewear Hin-and-forth, because the display can not be detected.
Result: It makes good pictures! With a great technology, but also "foolproof" can be set.
Maybe for some a suggestion, this camera similar use - to give older relatives.
