Designed to meet 4K production requirements, Sony's OSS FE PZ 28-135 mm f/4 G lens is a powerful zoom lens that covers from wide-angle to telephoto perspectives while adding many functions for your full frame, APS-C or camcorder system or still camera. the lens features a motorized zoom control with a variable speed and the ability to reverse the direction of rotation of the zoom. powering the zoom function is an SSM (Super Sonic Wave Motor) variator that allows an operation that allows an SSM (Super Sonic Wave Motor) operation. the zoom function is powered by an SSM (Super Sonic Wave Motor) that allows an SSM (Super Sonic Wave Motor) operation.
Variations in the angle of view when focusing (breathing) and axial displacement when zooming have been reduced, while five aspherical elements and three ED elements work with advanced multiple coating technology to minimize distortion and chromatic aberrations, while contributing to a sharper overall image with greater contrast and clarity.
Independent control rings are provided for zoom, focus and diaphragm (aperture) and the focus mode can be changed from automatic to manual by sliding the focus ring forward to maintain control at all times. three control rings have been designed to provide the proper torque for comfortable, responsive operation, and the scallop step in the rings has been designed for comfortable, non-slip control.
A constant maximum aperture of f/4 offers consistent performance over the entire zoom range and is especially useful when working with higher zoom magnifications in low-light conditions. Also benefiting from working in dim light or at the long end of the zoom range is Optical SteadyShot image stabilization, which minimizes the appearance of camera shake in up to four shutter speed steps.
