This lens combines the advantages of a normal, portrait, telephoto and long telephoto focal lengths, and comes with a reasonable speed for its zoom range. Although in films or on television, lenses with zoom ratios of 10 or more are used to create impressive zoom effects. But an increase in the zoom ratio means loss of brightness and a deterioration of image quality.
Focal length: 50-300 mm f4.5 L
Aperture ratio: 1:4.5
