## What is Lens Simulator?

Wondering what 85mm looks like on your Canon R7? Or how wide 24mm
feels on a Fujifilm X-T5? Point your phone and see — instantly.
Prospekt simulates any focal length on any camera body, live.

HOW IT WORKS

Choose a focal length from 14mm to 300mm, pick your camera body,
and see exactly what that lens sees — in real time, through your
iPhone. The field of view is 100% mathematically accurate.

Your iPhone automatically switches between its ultra-wide, wide,
and telephoto cameras to give you the best image quality at every
focal length. No guesswork. No approximations.
