Built specifically for 35mm film cameras — from the iconic Rollei 35 to Leica M-series, Nikon FM, Olympus OM, and any vintage manual 135 camera. Lux & Reach gives you instant exposure and focus data using only the iPhone in your pocket. METERING Three modes calibrated against industry standards. Spot for pinpoint exposure, ideal for zone-system shooters. Center-weighted with classic 60% center bias, mimicking analog SLR meters. Matrix multi-zone evaluative metering for high contrast scenes. EXPOSURE TRIANGLE Aperture, shutter speed, and ISO are linked through the classic exposure formula. Lock any two and the third updates automatically. Supports full, half, and third stops. ISO 6 to 6400. Aperture f/0.95 to f/64. Shutter 1/8000 to 30 minutes. Bulb mode reference. LIDAR RANGEFINDER (Pro / Pro Max only) Tap to read distance from the LiDAR sensor. Designed specifically for the Rollei 35 — the legendary compact 35mm camera with no built-in rangefinder, where every shot depends on guessing distance. Also perfect for any scale-focus or zone-focus manual lens, studio lighting setups, and cinematography focus marks. FOCAL LENGTH PREVIEW Preview the field of view at 21, 28, 35, 50, 75, 90, and 135mm. Scout compositions without changing lenses. HISTORY Every meter reading and distance measurement is logged automatically with timestamp. DESIGNED FOR THE FIELD 100% offline. No account, no internet, no telemetry.
