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

Magic Sonic ViewFinder presents you a precise framing preview for the real camera/lens combination you'll be shooting with, right where you stand with your iPhone / iPad. It simulates the field of view of digital cameras and can help thousands of professionals in filmmaking at the preproduction. PLEASE READ: this app does not turn your Apple device into an external monitor, but operates as a stand-alone director's viewfinder. The app contains ad banners, which can be turned off with additional in-app purchase. The app is a digital directors viewfinder -- it helps you see the field of view for your future shot. Select the camera from the menu and rotate the wheel to select the focal length of the lens. Supported cameras: - Alpha a99 II, 7RIII, 7RII - Alpha 7III, 7S II, 7R - Alpha a77, a6500, a6300, a5100 - FS100 / FS 700 - F3 / FS5 / FS7 - FX9 FF 6K / FF crop 5K / S35 4K - RX100 (1" sensor) - Venice 6K / 4K / 3.8K Magic ViewFinder simulates using tele adapters or anamorphic optics on your camera (see menu). From the menu you can also select the aspect ratio of the frame guide overlaying your image. Magic ViewFinder also lets you apply some commonly used color presets (also known as LUTs)to the live picture, which brings you even closer to the final shot. When you have found the right view, you may save it for future reference, with additional data like the focal length, date and time and camera / lens information. While taking a photo, you may lock exposure and turn on and off the auto focus to better control the captured picture. You can set camera to work in constant auto-focus mode, or lock the focus temporarily. You can also tap the live screen to focus on particular objects (which turns on the focus-locked mode). White balance may work in Auto, Locked or Manual mode. If the field of view of your real camera is wider than your in-device camera, the app adds 'padding' around the image, since the device cannot 'see' what is beyond. It is the best solution that we developed first amongst other viewfinder apps. Please note that position of your iPhone or iPad should correspond to the 'nodal point' of your real lens, which is somewhere in the middle of the lens. This point is, so to speak, the weighted center of the optics. Ad policy: Ads can be turned off (see below).
