This early reflex camera was based on the body of the Universal series, when introduced it was known as the Self-Focusing Reflex or simply the N&G Reflex. With the introduction of the Square Reflector it became the Long Focus Reflex and remained on sale for a few more years.

The focusing screen was the same size as the plate and so showed a landscape format, for vertical exposures the camera was held as for landscapes to focus and then turned on its side where the picture would be composed with the aid of a view-finder. N&G portrayed this as a benefit in that a revolving back need not be operated by the photographer. The mirror and shutter were inter-linked to prevent the shutter being set without the mirror being lowered, this prevented light reaching the plate. A rear focusing screen could be used for tripod work, the mirror could be locked in the up position when in this mode.
