Lens Review: Sony 28-75mm F2.8 SAM
The Sony 28-75mm F2.8 SAM is a versatile standard zoom lens designed for full-frame Sony A-mount cameras. Its constant f/2.8 maximum aperture allows for consistent exposure and depth of field control throughout the zoom range, making it suitable for various photography genres, including portraits and events. The lens features a Smooth Autofocus Motor (SAM) for responsive and quiet autofocus performance. Its optical design includes four aspherical elements and three Extra-low Dispersion (ED) glass elements to minimize aberrations and enhance image quality. The circular 7-blade aperture contributes to pleasing background defocus effects.
