It weighs a lot less. My pinky hurts and 99% of my photos are selfies, so I’d rather have less mass than more camera; I’ll rent a Leica if I want truly excellent photographs. Also my purse is hella full all the time so every less millimeter of phone makes it easier to get stuff out of the pockets, get phone out of purse, etc. Also it’ll fit with less bulge into my side-thigh pockets and pull less on the waistband, which is handy for my skirts and leggings and undershorts that all that have that.
