Helios lens is incredible

Helios have a sort of wonderful "lens defect" that causes the background (bokeh) to be swirtly.. to some it is an incredible effect that is not found on any other lenses in the market.. the 85mm is a very heavy lens as it has a metal body and glass lenses.. to be used primarily for portrait with high contrast to be able to maximize its effect.. a very recommended manual lens for both hobbyist and pro photographer..
