Well, two months ago I bought my wife a used Canon EOS 1100D to allow her express her photographer taler she showed some months ago, during a training Ju-Jitsu session for our daughters with a Japanese elder teacher (教師?) when someone put in her hand the DSLR of the Italian head of Ju-Jitsu dojos.
I chose it among the other because it allowed to install Magic Lantern
Magic Lantern is a free firmware addon for Canon EOS DSLR cameras that adds a host of features to assist photographers and videographers. Unlock your Canon DSLR.
Now I hesitate to install it. I don’t want to ruin her experience with a piece of experimental software. Had it been mine I would have installed it.
But it’s not mine anymore. I chose it, I bought it. But I donated it to her. It’s not “mine” anymore even thought everything mine is her and everything her is mine. True, it is but for higher goods.
Installing Magic Lantern would be plainly a whim of mine, an act of sheer selfishness.
So, no; I’ll leave her DSLR pristine, as I bought it.
