LiveMM vs Lens Simulator

--- Know your focal length. Every shot. LiveMM displays your real-time 35mm equivalent focal length and angle of view directly on the viewfinder — so you always know exactly what you're shooting. Whether you're a film photographer trying to match a composition on your phone, or someone who wants to develop a sharper eye for perspective, LiveMM speaks the language of real cameras. --- REAL-TIME FOCAL LENGTH OVERLAY As you zoom in or out, LiveMM instantly shows the 35mm equivalent focal length (e.g. 26mm) and angle of view (e.g. 77°) on screen. No lag. No guessing. HARDWARE-ACCURATE READINGS LiveMM reads the field of view directly from your iPhone's physical camera hardware using AVFoundation. The focal length you see is calculated from the actual optics of your device — not a rough estimate. LENS PRESET BUTTONS Instantly switch between your phone's physical lenses — 0.5×, 1×, 2×, and 3× — with a single tap. LiveMM automatically detects which lenses your device has at startup, so it works correctly on any iPhone without a device database. PINCH TO ZOOM Use standard pinch-to-zoom gestures for continuous zoom between lens presets. The overlay updates in real time throughout the entire zoom range, including digital zoom. PHOTO CAPTURE WITH EXIF DATA Capture photos directly in the app. The 35mm equivalent focal length is written into the photo's EXIF metadata, so your camera roll tells the full story of every shot. --- PERFECT FOR · Film and mirrorless camera photographers shooting with an iPhone · Photography students learning to see in focal lengths · Anyone who wants to understand what their phone's lenses actually see REQUIREMENTS · iPhone 12 or later · iOS 16.0 or later · Physical device required (camera features are not available in 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. 50+ CAMERA BODIES Canon: R5 II, R6 III, R7, R10, R50, EOS R, 5D IV Sony: A1, A9 III, A7R V, A7 IV, A6700, ZV-E10 II Nikon: Z9, Z8, Z6 III, Zf, Z50 II Fujifilm: GFX 100 II, X-T5, X-H2S, X-S20 Panasonic: S5 IIX, GH7, G9 II OM System: OM-1 II, OM-5 Leica: M11, SL3, Q3 Hasselblad: X2D, 907X Pentax: K-1 III, K-3 III Sigma: fp L Every major sensor format: Full Frame, APS-C (1.5x & 1.6x), Micro Four Thirds, and Medium Format.
