Features

What it does.

Live readouts

Aperture, shutter speed, ISO, white balance in Kelvin and scene EV, always on screen. Exposure stays automatic.

Exposure compensation

About -3 to +3 EV. Long-press the preview and drag up to brighten or down to darken, with an orange line showing the bias.

Real lenses

Choose 0.5x (about 13 mm), 1x (about 24 mm) or 4x (about 100 mm). These are the physical cameras, not a crop of the main sensor, and a haptic tap confirms the switch.

Full-resolution ProRAW

Shoots DNG at the largest size the lens supports, up to the 48 MP class. Files open in Lightroom, Capture One and any RAW editor.

Histogram and waveform

Switch between a live histogram and a luminance waveform with shadows, midtones and highlights zones. A clipping pill tells you at once if shadows or highlights are lost.

Focus and face lock

Tap to focus with clear corner brackets, enlarge them for precision, or tap a detected face to lock follow-focus on that person.

Monochrome preview

An optional black-and-white view for judging exposure and tone, with contrast and black point controls. It does not change your ProRAW file.

Immersive mode

Tap the eye icon to hide most controls and keep only the grid, focus, EV strip and shutter. Tap-to-focus and EV still work.

Built-in guide

A full guide sits inside the app, so the manual is always with you.
