I am executing a 3-minute unbroken tracking shot for a music video using a Canon 5D Mark III and a MoVI M5 house with a ring handle. The music video takes place at a house party moving from interior to exterior. Plenty of choreography in each frame and following two main characters. I want depth of field but with soft focus so as to limit the use of pull-focus. Does anybody have an specific suggestions as to what lens would be best for this criteria? I'm thinking a fixed lens like a 35mm f/1.4 Zeiss or a Sigma 30mm f/1.4 but those are my only leads. NEED HELP. Thanks.
