The SELP28135G is a powered zoom lens that has been created to satisfy professional optical and operational requirements for high-quality movie imagery, including 4K, when matched with a 35mm full frame format camera such as the α7S or a Super 35 format camcorder such as the PXW-FS7*. Focus breathing and zoom image shift have been reduced to an absolute minimum, while aspherical elements and advanced multi-coating technology effectively suppress aberration. Quiet operation is also a priority, so an SSM (Super Sonic wave Motor) drive system has been employed for precise, quiet zooming. Independent control rings for zoom, focus, and iris using physical stops are provided for the first time into an E-Mount an lens. Built-in Optical SteadyShot image stabilization adds to the extraordinary performance of this outstanding lens which is supporting a constant F4.
Superb 35mm full frame imagery. This top-quality powered zoom lens for 35mm full frame format cameras has been created to satisfy professional moviemaking requirements, including the high resolution 4K format. Angle of view variations while focusing (breathing) and axial displacement while zooming have been reduced to an absolute minimum, and aspherical elements work with advanced multi-coating technology to effectively suppress all types of aberration.
Three independent control rings. Independent control rings for zoom, focus, and iris (aperture) are provided for the first time in an α lens, and the focus mode can be switched from auto to manual simply by sliding the focus ring forward so control is maintained at all times. Zoom speed can be precisely controlled over a wide range, with zoom rotation direction reversal capability. All three control rings have been engineered to provide ideal torque for comfortable, responsive operation. Even the pitch of the scalloping on the rings has been painstakingly designed for comfortable, slip-free control.
Quiet operation. An SSM (Super Sonic wave Motor) drive system has been employed for precise, quiet zooming. Focus noise has been minimised by reducing the weight of the focus element group and driving it with a responsive linear motor. Smooth, quiet iris operation also contributes to enhanced usability.
