Well, the 13 Ultra also had the f/1.8 aperture on both the ultrawide and the 3.2x telephoto modules.
Let's recap some things from the teasers:
Main:
- Updated LYT900 sensor
- Increased f/1.63 aperture
- Stepless vario aperture
Ultrawide:
- Nothing known yet
3.2x telephoto:
- Free floating lenses for macro shots
5x telephoto:
- Increased f/2.5 aperture
- 6P lens like the 3.2x camera (compared to the 5P lens from last year)
- Free floating lenses for macro shots.
Aside from the main camera, the 14 Ultra is more of a refresh rather than an upgrade.
