MovieTube ST Lens Adapter.

It’s all about the glass.
Stick your DV / DVCam / HDV on the back and what ever 35mm glass you can get hold of on the front. Presto. Depth of field. There’s no moving parts, so no noise and no spinning grain structure. (NB : Lens Adapters required)

It provides the same depth of field and viewing angle as the 35mm format.
