Do people really like that aliased look? Every picture has very obvious aliasing. It's the first thing I noticed, within less than a second. And aliasing is an especially bad artifact because image processing algorithms assume band-limited data. There's no way to get something natural looking from those images.
It seems almost unbelievable to me that a camera supposedly focused on quality would do this, so I wonder if DXOMark, despite claiming to be "The reference for image quality", actually destroyed image quality with terrible downscaling. I know people like sharpness, but if you insist on pushing it this far, ringing is far less objectionable than aliasing.
- jrockway 10y agoPeople seem to like the aliasing, paying more to have the lowpass filter removed from their DSLR's sensors, despite the fact that there is no way to fix the aliasing in post-processing. "It won't happen to me," I guess is the attitude. Reviewers that check for MTF and end it there are also problematic. There is more to photography than line pairs per millimeter.

- sp332 10y agoCan you fix ringing in post? And personally, if I'm going to be stuck with one or the other, I'd much rather have aliasing than ringing.
