The Minolta Portrayer is not your average diffusion filter: it provides some glow and softness, but preserves a lot of the sharpness that's lost with most diffusion or soft focus filters. Minolta claims that this is because it uses "state of the art technology in wave optics," and why not? Sounds about right. This is a complete set of two filters, marked S1 and S2, in a fancy carrying case. In excellent condition. These filters are designed to fit lenses with a thread diameter of 55mm.
