App Description This app comes with three sample camera formats pre-installed, allowing you to try all of the features. If you are satisfied with the functionality, you can purchase “All Camera Formats” via in-app purchase. “All Camera Formats” includes about 1,000 presets as well as unlimited custom formats that you can create yourself. Details of the preset camera formats are listed on the in-app purchase screen, so please check there. The app works on both iPhone and iPad. However, the iPad version is for previewing data captured on iPhone and does not support shooting with the iPad’s camera. What this app does This application is designed to support lens selection during shooting, location scouting, and meetings. It helps you determine the focal length of the lens you need. The app features three main modes: • Live View Mode • Capture View Mode • Distance Conversion Mode Each mode also offers two drive options: • Zoom Lens Drive Mode • Prime Lens Drive Mode Mode Details Live View Mode View the live feed from the built-in camera and use the on-screen slider (in Zoom Lens Mode) or buttons (in Prime Lens Mode) to zoom, which allows you to calculate the focal length you need. This works much like an analog angle finder. Capture View Mode Take a snapshot in Live View Mode and then adjust it. Since Capture View Mode displays the full-resolution image, it offers far higher clarity than Live View Mode, and because the image is fixed, there is no blur — making it suitable for checking angles even in the telephoto range. Distance Conversion Mode This mode does not use the camera image. Instead, you input the distance to the subject, and the required focal length is calculated. To make it visually intuitive, a CG figure scales accordingly. This is particularly useful during discussions or planning. Other Features • Save captured images to review framing later. • Record and save orientation and location information. • Supports both metric (meters) and imperial (feet) units. • Includes an editable lens list that you can freely add to, delete, or rearrange for reference. Subscription Details • “All Camera Formats” is available as an annual subscription, which automatically renews each year unless canceled. • Payment will be charged to your iTunes account at the time of purchase confirmation. • Subscriptions can be restored on all iOS devices using the restore function in the settings page. • Unless auto-renewal is turned off at least 24 hours before the end of the current period, the subscription will automatically renew. • Your account will be charged for renewal within 24 hours prior to the end of the current period, and the cost of renewal will be specified. • Subscriptions can be managed by the user, and auto-renewal can be turned off in the account settings after purchase. • Any unused portion of a free trial period will be forfeited when the user purchases a subscription. ○Privacy Policy http://anitya.link/privacy-policy_en.html ○Licence Agreement http://anitya.link/license-agreement_en.html ○Developer Website http://anitya.link/lensagent_en.html
