Lens Simulator: Prospekt app analytics for October 9

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.
