Huawei P10 Lite: Crop Factor, NPF Rule & Hyperfocal Chart

Name: Huawei P10 Lite
Brand: Huawei

The Huawei P10 Lite uses the built-in lens (fixed-lens camera) with a 6.88× crop factor (about 5.2 × 3.5 mm sensor). Below: equivalent focal lengths, maximum shutter speeds for sharp stars, a hyperfocal distance chart and how to check the shutter count.

Equivalent focal length & field of view

Lens focal length	Full-frame equivalent	Diagonal FOV	Horizontal FOV
8 mm	55 mm	42.8°	36.0°
10 mm	69 mm	34.8°	29.1°
12 mm	83 mm	29.3°	24.5°
14 mm	96 mm	25.2°	21.0°
16 mm	110 mm	22.2°	18.5°
18 mm	124 mm	19.8°	16.4°
20 mm	138 mm	17.8°	14.8°
24 mm	165 mm	14.9°	12.4°
28 mm	193 mm	12.8°	10.6°
35 mm	241 mm	10.2°	8.5°
50 mm	344 mm	7.2°	6.0°
85 mm	585 mm	4.2°	3.5°

Multiply by the 6.88× crop factor for the full-frame equivalent field of view.

Milky Way exposure: NPF and 500 rule

Focal length	NPF @ f/1.8	NPF @ f/2.8	Strict NPF @ f/2.8	500 rule
8 mm	16.9 s	21.2 s	11.6 s	9.1 s
10 mm	13.5 s	17.0 s	9.3 s	7.3 s

NPF = (35 × f-number + 30 × pixel pitch) ÷ focal length, with a pixel pitch of 2.4 µm (typical for this format — exact resolution not in our database). The strict version (Michaud's detailed NPF for the galactic core) gives pin-point stars at 100% view; the 500 rule is a loose rule of thumb that shows trailing on modern sensors.

Hyperfocal distance chart

Focal length	f/2.8	f/5.6	f/8	f/11	f/16
10 mm	8.1 m	4.1 m	2.9 m	2.1 m	1.4 m

Focus at the hyperfocal distance and everything from half that distance to infinity is acceptably sharp (circle of confusion 0.0044 mm). Use the hyperfocal calculator for other settings.

How to check the Huawei P10 Lite shutter count

Not every maker writes a shutter count into image files. Try `exiftool -a -G1 -s image` on an unedited original and look for a tag containing "Shutter" or "Count".

ExifTool tag: (varies). Always test an original, unedited file straight from the card.

FAQ

What is the crop factor of the Huawei P10 Lite?

6.88×. A 24 mm lens frames like a 165 mm lens on full frame.

What shutter speed should I use for the Milky Way with the Huawei P10 Lite?

With a 8 mm lens at f/2.8, about 21 seconds keeps stars sharp (NPF rule).

How do I check the shutter count on the Huawei P10 Lite?
