The Sony FE PZ 28-135mm f/4 G OSS Lens is a wide-ranging zoom lens that covers wide-angle to telephoto perspectives while adding many features for your full-frame, APS-C, or E-mount camcorder or still photography camera system. The lens features a powered zoom control with a variable speed and zoom rotation direction reversal capability. Powering the zoom function is an SSM (Super Sonic wave Motor) drive that allows precision and quiet operation. Focus noise is also minimized through weight reduction of the focus element group and use of a linear motor.Angle of view variations while focusing (breathing) and axial displacement while zooming have been reduced while five aspherical elements and three ED elements work with advanced multi-coating technology to minimize distortion and chromatic aberrations while also contributing to sharper overall imagery with enhanced contrast and clarity. All three control rings have been engineered to provide the right amount of torque for comfortable, responsive operation and the pitch of the scalloping on the rings has been designed for comfortable, slip-free control.Features Sony's original Nano AR Coating technology designed to effectively suppress reflections that can cause flare and ghosting. The precisely defined regular nano-structure allows accurate light transmission, contributing to high-quality images, even more so than lenses with coatings that use an irregular nano-structure.The focus mode can be switched from auto to manual simply by sliding the focus ring forward so control is maintained at all times.
