The X7 relies on a dedicated mount system built for carrying prime lenses. You have choices of 16mm, 24mm, 35mm and 50mm lenses, all of which have a maximum f/2.8 aperture. You should get a shallow, film-like depth of field for closer shots regardless of which lens you use. The 16mm lens has an ND 4 filter, while all the other lenses tout mechanical shutters.
Software may play as much of a role as the optics themselves. There’s a Cinema Color System to offer more flexibility in the editing booth, and a new mode imitates the behavior of film cameras to help preserve info.
To no one’s surprise, airborne cinematography won’t come cheap. The base Zenmuse X7 costs $2,699 by itself, while every lens save for the 50mm costs $1,299 (the long-ranged lens costs $100 less). Completists will probably want to buy a four-lens bundle at $4,299. At least you won’t have long to wait before you can start on your aerial magnum opus, as the X7 and its lenses start shipping in early November.
