35mm Depth of field Adapters

These adapters enable movie or stills lenses to be used on video cameras, by having the video camera record an image focused on to (usually) a ground glass screen similar in size to the lenses coverage at the film plane (film camera's gate area). This then keeps the focal length and depth of field of the lenes as it would be on the movie/stills camera it was designed for. Also, on the ground glass at least, there is no chromatic aberation introduced. The downside is the ground glass introduces a loss of light and sharpness depending on the quality of components and design.
The simpler designs also invert the image (much as a film camera does!) and this has to be inverted again in editing.

in no particular order:

probably the best of the image flip adapters (and most expensive)
though I used one recently and dust on the prism was visible in the viewfinder and final footage (Z1).
