For full ergonomic focus control, order this O-Focus DM Cine Lens Pro Kit from OConnor. By connecting a rotating dial to your focus ring, it allows you to easily and comfortably adjust your focus while you film. Precision is key and that was considered in this follow focus’ design with a rotation ratio of 1:0.75 and therefore a 1:1.4 rotation ratio with the included cine Studio Handwheel. This follow focus system is discrete and versatile, capable of attaching to a cine lens of any diameter. Additionally, the handwheel can be moved around its off-set axis to reveal lens markings or lift off the ground when your camera is set down. The handwheel can be attached and used on either side of the bridge rod - left or right of your camera. Order now and discover the highest level of follow focus quality.
