Best optical Performance for high-quality images

This super telephoto lens includes two ED (Extra-low Dispersion) optical elements. The second and fifth lenses use ED glass, to effectively minimize spherical and chromatic aberrations, while delivering high-resolution, fine-detailed images with rich contrast from the image’s center to its edges and minimal color bleeding at any focal length setting.

The optical system uses an inner focus construction, which is supporting the high demand to the image quality and also allows a significantly more compact design.
