Xiaomi 17 Ultra

HPE (1/1.4", 200MP) periscope and new lens group

Engineering prototype with a minimum aperture of F3.0± and a maximum aperture of F2.3± within the variable focal length range

Let's analyze based on the available information

The Xiaomi 15 Ultra uses a 1/1.4" HP9 sensor at 100 mm (4.3×) with f/2.6. Since the Xiaomi 17 Ultra will use the same-sized 1/1.4" HPE sensor, we can use the 15 Ultra’s f/2.6 at 100mm as a reference—aperture scales proportionally with focal length

The ratio between f/3.0 and f/2.6 is 3 ÷ 2.6 ≈ 1.15
New focal length: 100 mm × 1.15 = 115 mm
Xiaomi 15 Ultra: f/2.6 @ 100 mm
Xiaomi 17 Ultra (long end): f/3.0 at 115 mm

The ratio between f/3.0 and f/2.3 is 3 ÷ 2.3 ≈ 1.30
Short end focal length: 115 mm ÷ 1.30 ≈ 88 mm (DCS gave approximate f-numbers, so round to 85 mm)

Thus, the Xiaomi 17 Ultra periscope should span roughly 85mm (3.7x) with f/2.3 to 115mm (5x) with f/3.0 using continuous optical zoom
