Sony FE 28-70mm f/2 GM - Sony E-mount

The FE 28-70mm f/2 GM is a large-aperture standard zoom that offers a constant f/2 brightness throughout its range, rivalling the performance of prime lenses. It uses advanced optical elements to control spherical aberration and four XD linear motors to drive the heavy glass elements quickly. It is designed for photographers and videographers who require the versatility of a zoom without sacrificing the light-gathering capabilities of a fast prime. Due to the size and weight of the internal glass, it is important to check the zoom mechanism for any stiffness or uneven resistance. SDS inspects the lens for optical centring and ensures the XD linear motors are operating quietly. We also check the zoom smoothness switch and verify that the weather sealing remains intact, particularly around the extending lens barrel.
