Those who would like to deal with macro photography, but there is no Lens will make up from about EUR 250,00, accesses a retro adapter. This product is made in China. This means that the black coating of the adapter (aluminum) dissolves after the first two days of use in many places from. The product quality based on the coating is very modest as it were sobering up. However, the possible with the adapter extensions are great. And offer much better (more extreme) options, such as with the use of Lens adapters or extension rings. I am satisfied with the results of the photos to very satisfied.
