I think that you will have another starter lens to add to your collection. It is a simple 4 element design in three groups. Although it is capable of producing good enlargements, considering the low cost of excellent lenses these days; I would invest in one of the following: Rodagon, Apo Rodagon, El Nikkor, Componon, Componon S and others. Choose a 6 element design as these are generally sharper.
