On the one hand it is amazing that someone actually started working on such project.

On the other hand concerning handling it is rather a 16mm camera loaded with a Super 8 cassette so to say.
I have no problem mounting and handling one of my S-8 cameras in a very elaborated way so that in the end only the economics of film format would make a difference.

However a great part of the charme of S-8 lies in the compactness and handling of the camera. That does not take away that I often wanted other or more features on my S-8 cameras and thought of modifications.
