Lumen

Lumen is a camera that doesn't hide its values.

EV, ISO, shutter, focus and white balance are on screen as numbers, always —
and one tap locks all of them. Recompose without your exposure drifting.

■ Precise colour — free
Temperature in Kelvin and green↔magenta tint, together, on one two-axis pad.
A precision the competition doesn't offer. In Lumen it's free.

■ It won't die at the decisive moment
Survives incoming calls and thermal throttling.
Shoots from the volume button. Launches straight from the Lock Screen.
All of that is free too.

■ Free, forever
