As DPs, we often decide whether our project should be shot with primes or zooms based on the desired look and logistics of the shoot. However, there are plenty of times when we need to use both. Maybe we are handheld, shooting outside for some scenes, so zooms make the most logistical sense. Yet for other portions, we are shooting portraits or interviews, and we want the added optical quality, control, and stop of a prime. Then, our main objective becomes making sure the lenses match and will cut together cohesively.
