Change the plane of focus to direct more attention to the subject and adjust depth-of-field as you see it, with no need for computers.
Precise movements allow a ± 10° Tilt and a ±12mm Shift with a rotation of the shift/tilt functions +/-90° in any direction for superb perspective control.
A macro focus capability of 39cm means 1:2 life size images can be delicately focused with added control over perspective and depth-of-field.
Aspherical and UD lens elements minimise chromatic aberration while Air Sphere Coating minimises ghosting and flare.
A 90mm focal length gives a flattering compression for portraits with the added benefit of perspective control to correct verticals and maximise depth-of-field.
