Read full description

Free tools Quick Diopter is the on-set close focus tool. Enter marked focus and target distance to get ideal diopter power, the nearest standard glass (+1/8, +1/4, +1/2, +1, +2, +3), a comparison table of resulting focus distances, and a BEST FIT highlight for the strength to pull from the kit. Results update as you type or tap +/-. Meters or feet. Diopter Result is for kit check. Enter marked focus and a known diopter strength to see the resulting subject distance. Depth of Field shows near, far, and total DOF for a focus mark using the format circle of confusion, plus how much sits in front of the mark and how much sits behind. Built for focus pulls and stop decisions. Hyperfocal gives hyperfocal distance and near limit for near-to-infinity coverage. ACam Pro (lifetime unlock) One non-consumable purchase. Restore on any iPhone or iPad. Precision Mode is offset-aware diopter planning with DOF context. Formats include Super 35, ARRI ALEXA 35 Open Gate, Full Frame, and Large Format / VistaVision.

Split Focus returns the focus mark and stop that hold two subject distances. Viewfinder and Split is composition planning: horizontal and vertical FOV, frame width and height at subject distance, and a place-and-rotate split-diopter line for staging notes.
