The LUMIX S PRO 16-35mm F4 extends the Panasonic S focal length range in the wide-angle segment. The versatile zoom ranges from super wide-angle to classic reportage focal lengths. Both photos and videos benefit equally from its high imaging performance over the entire focal length range. Despite its compact design, a very powerful linear motor with two magnets drives the AF focusing element. High-speed focus control on the sensor takes place at a maximum of 480 fps in order to accurately track even fast subjects. Fast switching between AF/MF and precise manual focusing is possible at any time thanks to the FocusClutch function. During video recording, a mechanism suppresses any pumping during focusing, which can be annoying with interchangeable lenses designed for purely photographic use. The robust, dust and splash-proof*4 construction can withstand tough use even in difficult conditions down to 10 degrees below zero. The filter size is 77 mm.
