The Atomos Ninja V and Ninja V+ are two very popular field monitors and recorders that are often used to boost the performance of your camera. For instance, the LUMIX GH5S can be paired with either of these monitors for ProResRAW.
The GH5S initially made news when it was introduced in 2018 with support for a micro four thirds format. and has now been updated to support ProResRAW with the Ninja V or the new Ninja V+.
This workflow makes for a manageable, light weight system to produce high quality video in the field. The GH5S is a light weight camera geared for recording and low-light performance. Pair that with these five inch, high nit monitors and you have an excellent cinematography solution.
