Open your Waveform and Vectorscope. Do not rely solely on your monitor. Use the scopes to verify exactly how many stops of shadow detail remain visible above 0 IRE.

: Check noise levels at ISO 800 versus ISO 12,800.

The FX6 features a base ISO of 800 and a high-base ISO of 12,800. Analyze test clips shot at ISO 12,800 in dim environments. Pay close attention to the shadow areas; look for chroma noise (color splotches) versus luma noise (fine grain). The FX6 is renowned for keeping low-light grain remarkably clean and film-like. Codec Performance: XAVC-I vs. XAVC-L

Apply a standard Sony S-Log3 to LC-709A LUT. Push the exposure slider up and down by two to three stops. Observe how well the colors hold together in the skin tones and check if the shadows break down into blocky digital noise. Test 2: Playback Performance
