Short description:

Autofocus telephoto lens with a minimum distance to the shooting object of 3 m. The use of optical elements with extra low dispersion in the design provides high-quality images with high resolution and contrast and minimal chromatic aberrations. Lenses are made of expensive optical glass of special grades with unique characteristics and properties. The internal focus mechanism eliminates the redistribution of weight during focus and speeds up the autofocus process. The included lens hood protects the front lens and reduces flare and flare in side lighting.
