FieldMonitor gives you wireless monitoring & control for Canons, Panasonics, Sonys, and Teradeks. IMPORTANT: DO NOT buy FieldMonitor without reading this ENTIRE description! Test your camera with its native Wi-Fi app to make sure your workflow and recording formats are supported BEFORE buying FieldMonitor. Make sure you have the controls you need with the native app, and that image quality and lag are acceptable. Contact me if you have any questions. • FieldMonitor has the same latency, resolution, and reliability as your camera’s native app. • If a camera control or feature does not work with the native app, it won’t work with FieldMonitor. • FieldMonitor has NO playback, review or download capability. • In areas with busy Wi-Fi networks and/or sources of radio interference, performance cannot be guaranteed, whether using FieldMonitor or your camera’s native app. WHAT IT DOES: FieldMonitor™ lets you monitor picture, exposure, and color on supported Canon™, Panasonic™, and Sony™ cameras, and Teradek™ H.264/HEVC transmitters. FieldMonitor runs on iPhone, iPad, iPod touch, and Apple Silicon (M1) Mac. Use markers to show safe areas, aspect ratios, and framing grids. Desqueeze anamorphic images, cropped to your final aspect ratio. Flip the image on either axis. Focus Assist helps you nail focus. Use a waveform monitor, vectorscope, histogram, false color, and 3D LUTs. With iPhone 5S or later, iPod touch 6G or later, iPad Air or later, iPad mini 2 or later, and iPad Pro, you can see a false-color picture with adjustable levels. With a supported camera and lens you can start/stop recording, control exposure and color settings, and zoom or focus remotely. Controls are designed for fast, realtime adjustments. See the FieldMonitor website for details.
