B-roll slow motion (4K120)

The constraint is smooth slow motion, which means a high frame rate and the light to feed it. Shoot 4K120 and it plays back at a fifth of real speed — gorgeous for pouring liquid, blowing leaves, a passing subject. Keep the 180° rule with a 1/250 shutter, open to f/4, and let Auto ISO cope. Because 120p needs more light, shoot in bright conditions and expose carefully; motion that would look ordinary at 24p becomes hypnotic slowed down.

Watch out for the 1.58× crop that 4K120 adds on top of the sensor’s own. Your 10mm frames like roughly a 24mm equivalent, so even the widest lens is no longer wide — plan the framing for that reach and step back to compensate. In sun the 1/250 shutter can still be too bright, so keep an ND handy, and remember autofocus and some features are more limited in high-speed mode, so keep the shot simple.
