Combined with advanced manufacturing techniques, the result is a lens with very sharp picture
quality with less color abberation which is considered the most harmful factor in the field of
telephoto photography.

This lens is a highly complex, precision-made, optical instrument it is also compact and lightweight.
It is ideally suited for wildlife and sports photography. It has a fixed aperture of f8. It comes with
a soft pouch and three (3) rear mounted 30.5mm filters - ND2, ND4 and Skylight.

Can't get sharp shot
By Valeriy Tolkov
I've installed it on tripod and tried to make sharp image of something not so far, like tree flower. It comes with strong glow. Relly strong. I am not sure, if its supposed to be like that for mirror lenses or it is a refraction of some sort in my particular one, but the results are just bad. And no stabilisation, no autofocus, no light control. And no way you can use it for "sport and nature photography". So, I played a little and returned it.
