Manufacturer description

The extra-low-dispersion optical element used in this lens reduces chromatic aberration, for performance levels not possible with conventional optical glass. The rear focus system features a rear elements group that moves inside the barrel. This allows a far more compact lens design, as well as better balanced, smoother and faster focusing. The focal length is ideal for most long-distance applications.
