Zoner Lite

Zoner is an easy to use zone focusing app for photographers, behaving like an actual lens where you turn (swipe) to focus and set aperture. Most film/sensor types are supported, from small 2/3" digital sensors to 8x10 view cameras.

Zoner Lite supports APS-C (1.5x crop) and full frame/35mm camera formats, and two lenses: 50mm and 85mm. Upgrade to Zoner Pro which supports formats from small cameras with 2/3" sensors to 8x10 view cameras, and lenses from 6mm to 800mm.
