This test report belongs to a different type: 16-300mm F3,5-6,7 DC OS | Contemporary (Sony-E) (Sony E, APS-C / DX)
The lens is designed for use on cameras with the Canon RF bayonet mount.
The 16-300 mm focal length range covers everything from wide-angle shots to powerful telephoto photography.
The maximum aperture of F3.5-6.7 is relatively small in the telephoto range, which limits light collection in dark environments.
