CineLoupe
Director's viewfinder for pros
$5.99
CineLoupe is a cinematographer's viewfinder that reproduces cinema camera sensor modes and lenses on your iPhone — including the bokeh.
BOKEH YOU CAN SEE
Using the iPhone's LiDAR (or stereo) depth, CineLoupe computes depth of field from the chosen focal length, T-stop and focus distance and blurs the live image accordingly. Tap to focus. Anamorphic lenses render with the correct squeeze and oval bokeh.
SENSOR MODES, NOT JUST CAMERAS
Crop by the actual imaging area of each recording mode — ALEXA 35 4.6K 3:2 Open Gate vs 4K 16:9, VENICE 2 8.6K 3:2 vs 5.8K 6:5 anamorphic — for ARRI, SONY, RED, Canon, Blackmagic, Nikon, DJI, FUJIFILM and more.
A LENS LIBRARY THAT MATCHES THE RENTAL FLOOR
165 series and 1,400+ lenses: ARRI Signature / Master / Ultra Prime, ZEISS Supreme, Cooke S4/S7/S8, Leitz, Angenieux Optimo, FUJINON Premista, Canon Sumire, SIGMA, DZOFILM, LAOWA, Tokina Vista and many more. Browse prime / zoom → mount → series → focal length, or type any focal length and T-stop manually.
FRAME LINES, AS MANY AS YOU NEED
Overlay 16:9, 2.39, 9:16 or any ratio and percentage on the open gate at once, with optional outside shading and burn-in.
TAKES THAT BECOME THE SCOUT REPORT
Stills (HEIC) and video (HEVC / H.264 / ProRes, 1080p / UHD, Apple Log) with camera, mode, lens, focal length, T-stop, focus distance, time, GPS, heading and scene/take burnt in. Mark OK takes and export a PDF with maps, shooting order, sun position and a location checklist. Optional auto-upload to your own Google Drive or Dropbox.
RE-SIMULATE LATER
Stills keep the raw frame and depth map, so you can revisit a take with a different camera, lens, T-stop or focus and save it as a new take.
SUN POSITION
Sun azimuth and elevation overlaid on the finder, scrubbable through the day, with sunrise, sunset and golden hour.
Requires iPhone 12 or later. LiDAR (Pro models) gives the best depth; the ultra-wide camera extends the wide end.
Simulations are optical approximations and do not reproduce distortion, vignetting, cat's-eye bokeh, breathing or color of real lenses. Camera and lens names are trademarks of their respective owners; CineLoupe is not affiliated with any manufacturer.
Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
• The storyboard now plays back in cut order. A clip runs only the part you trimmed; a still holds for the seconds you set.
• A camera and lens can be saved together as a rig and recalled from the gear list in one tap.
• Text size is now adjustable from S to 2XL — the finder, the panels and the burn-in strip all follow.
• After an update, the app shows what changed on first launch.
