Wi-Fi WFM

FieldMonitor
turns your iPhone®, iPad®, or iPod touch® into a wireless picture monitor / waveform monitor / vectorscope / histogram. See exactly what your camera is doing, without tethering your camera — or yourself — to a hardwired monitor and set of ’scopes.

FieldMonitor works with compatible Canon™, Panasonic™and Sony™ cameras, and with Teradek™ H.264 transmitters (Teradek monitoring requires iOS 10 or later).
  • Full-screen monitoring of your signal, with or without engineering ’scopes.
  • Onscreen markers: frameline and mask with adjustable safe areas and aspect ratios; several grids, center markers, and a customizable crosshair.
  • Focus Assist with variable sensitivity and four peaking modes (for camera sources only, not Teradeks. On iOS 11, focus assist requires iOS 11.2 or later).
  • 3D LUTs to view camera images: use the built-in LUTs or import your own .cube LUTs (camera sources only).
  • On modern iDevices, you can also see a fully-adjustable false-color overlay for direct exposure verification.
  • H and V Image Flip.
  • Anamorphic desqueeze for 1.33x, 1.5x, 1.8x, and 2.0x lenses.
  • With a compatible camera you also get start/stop, exposure, color balance, and focus controls, so you can maintain essential control even while recording (FieldMonitor provides a limited set of controls intended to supplement or replace on-camera adjustments while recording under Wi-Fi control. It does not replace Canon’s Camera Connect, Panasonic’s Image App or Lumix Sync, or Sony’s Imaging Edge Mobile for more comprehensive control, configuration, playback, and image transfer).

Before buying FieldMonitor, test with your camera’s native Wi-Fi app: FieldMonitor can’t make your camera do anything that the camera’s native app can’t make it do! If you're not happy with how your camera’s native app performs or the camera control it allows, you won't be happy with FieldMonitor either.

  • If your camera can’t shoot video using its native app, it won’t be able to shoot video using FieldMonitor.
  • FieldMonitor talks to your camera the same way your camera’s native app does. It will have the same range, resolution, reliability, and latency as the native app. If the native app performs poorly, then FieldMonitor will, too.
  • FieldMonitor only provides the same camera controls as the native app does. For example, if the native app doesn’t allow tap-to-focus, manual focus, face detection, in-camera peaking, or image mag with your camera, then FieldMonitor won't either. If you can’t set the focus point with the native app, you won’t be able to set it with FieldMonitor. If your camera won’t allow log shooting or Picture Profiles with the native app, it won’t allow log shooting or Picture Profiles with FieldMonitor.

FieldMonitor does not provide playback functions, menu controls, or image download capability, even if your camera’s native app does.

FieldMonitor does not control or monitor other iDevices. If you are using an iPhone, iPad, or iPod touch as your camera, look at FiLMiC Pro and FiLMiC Remote instead.

FieldMonitor is designed primarily for video production. If you are taking still photos, you might prefer something like Cascable instead.

Notes
Canon EOS DSLR and mirrorless cameras 512x288 Yes Yes Canons can’t output a clean HDMI feed when Wi-Fi remote control is active, so only internal recording can be used. No peaking display. Latency: 5–7 frames @ 24fps typical.
Panasonic Lumix cameras using Image App or Lumix Sync remote control (S1-series compatibility requires iOS 9 or later)
640x360
320x180
Yes Yes GH4s can’t record 10-bit when in Wi-Fi remote mode. Some cameras only transmit 320x180 images. Camera’s peaking display may not available while recording. Latency: 4 frames @ 24fps typical.
Sony “Smart Remote” cameras (A6300, A6500, A7Sii, A7Rii, etc.)
1024x576
640x360
Yes Yes “Smart Remote” Sonys disable Picture Profiles and other features in Wi-Fi remote mode: no S-Log, no S&Q motion! No tap-to-focus control in movie mode. No focus mag or peaking. Latency: 5–6 frames @ 24fps typical.
Sony “Ctrl w/ Smartphone” cameras (A6400, A6600, A7iii, A7Riii, A9, A99ii, etc.)
640x360 Yes Yes S-Log works, S&Q motion works. No focus-area display or tap-to-focus control; no battery or storage display. No focus mag or peaking. Latency: 5–6 frames @ 24fps typical.
Sony* “Ctrl w/ Smartphone” cameras (cameras with * after their name in FieldMonitor: A1, A7Siii, A7Riv, A9 version 5+,  etc.)
1024x576
640x360
Yes Yes S-Log works, S&Q motion works. No focus-area display. Tap-to-focus control only on A1 &A7Siii in movie mode. No focus mag or peaking. Latency: 3 frames @ 24fps typical. 1024x576 in “PC Remote” mode only.
Teradek H.264 transmitters depends on Teradek settings;
480i to 1080p
No No Requires iOS 10+. H.264 streams only. Latency: 4+ frames @24fps depending on encoder settings.
Fujifilm X-T3 and X-T100 cameras only: Fujifilm video functionality when using wi-fi remote control is very poor and FieldMonitor cannot improve it. Using a Fujifilm for video with wi-fi control is not recommended; FieldMonitor’s Fujifilm support is being maintained for existing customers and no further development is planned. 640x360 Yes Yes X-T3 only records 1080p/29.97. X-T100 only records 720p/24. No on-camera controls or displays; the camera body goes dead. No manual focus with focus-by-wire-lenses. No HDMI monitoring or recording. No tap-to-focus control in movie mode. No focus mag or peaking. See “Fujifilm issues” for full details. Latency: 2–3 frames @ 24fps typical.

  • Audio monitoring is not possible with camera sources, only with Teradeks.
  • If your camera lacks a mode dial or switch to choose between stills and movies, you won't be able to switch modes using FieldMonitor.
  • FieldMonitor (like any other live monitoring and control Wi-Fi app) depends on having a clear Wi-Fi channel for communication. In areas with many busy Wi-Fi networks and/or sources of radio interference, performance cannot be guaranteed. Test for adequate performance using your camera’s native app before buying FieldMonitor!



Screenshots and Videos

Not all features and functions shown are available with every camera, in every mode, regardless of the iDevice being used.
  • Panasonics in manual-focus mode provide the richest set of Wi-Fi controls and functions.
  • Panasonics in AF mode and Sonys show fewer focusing controls. You can’t set the focus point on most Sonys in movie mode.
  • Many “Ctrl w/ Smartphone” Sonys do not display focus area, battery level, or storage space.
  • Teradeks have no camera controls, LUT capability, or Focus Assist.
  • Older iDevices with A6 or earlier processors can’t show false color.

Full screen monitoring: camera controls at the edges, plus a focus-area rectangle when the camera provides it (Panasonics and Smart Remote Sonys only, and only in certain focusing modes).

Typical Panasonic controls in manual-focus mode
Typical Panasonic controls in manual-focus mode. Panasonics send storage and battery-level information. Camera battery level shown with PWR: label, iDevice battery shown with the i: label.

Typical Sony controls in manual-focus mode
Typical Sony controls in manual-focus mode. This Sony does not send storage or battery information, and the AF button only works in AF mode. iDevice battery shown with iPWR: label.

Display one or three ’scopes and set up how they should appear. There are frameline, mask, grid, center, and custom markers, too. You can hide or show camera controls, ’scopes, markers, and other embellishments as you see fit, simply by tapping the screen.

False-color display allows setting each of the color levels (false color requires iDevices with A7 or later processors).

Focus Assist gives you fully adjustable in-app sharpening, like an analog peaking control (Focus Assist is only available for camera sources, not for Teradeks).

Focus Assist’s Edge Mode really emphasizes where focus is placed.

Many Panasonic cameras offer a peaking control in manual-focus mode (in STBY only for most cameras, though the GH5 displays it while recording).
