If you’ve ever wanted a professional monitor without all the extra gear, there’s a super handy app called Monitor Plus. It works with Sony cameras and basically turns your smartphone into a full-fledged monitor—wirelessly. No cables, no extra transmitters, just your phone.
The app is available on both Apple App Store and Google Play, and the free version gives you live view plus basic camera controls. If you upgrade to the pro version, you get full pro-level monitoring features. Right now, it supports cameras like the Sony a7R IV, A9 Mark II, a7C, a7S III, A1, FX3, CV1, CVE 10, and a74. Not all models are supported yet, but hopefully more will be added soon.
With the app, you can control things like shutter speed, aperture, ISO, white balance, autofocus, and even start/stop recording. It also shows SD card memory, autofocus areas, picture profiles, and more. The pro version adds advanced tools like zebras, false colors, RGB waveforms, grids, focus pulling, and even a chroma key function for green screen work.
One of the coolest features? You can use your phone to track focus and mirror images, plus add custom LUTs or overlays for your footage. Basically, your smartphone becomes a surprisingly powerful and portable monitor, perfect if you don’t want to carry a separate, heavy setup.
Whether you stick with the free version for basic monitoring or go pro for full control, this app is a game-changer for anyone with a compatible Sony camera.
