- The Mirror Box (1957) screws into the body's 39 mm thread and holds a mirror that flips up on a double cable release; its lenses focus by their own helicoid or by a bellows. The Mirror Box 2 (1958 per lens-db and the museum's M-lens dates; 1961 per Leica Copies Japan) clips onto the Canon 7's outer bayonet and takes its own three-lug lenses — the M135 and M200 — and the 400 to 1000 mm heads through an intermediate tube and Bellows R. The two boxes' lens mounts do not interchange (Leica Copies Japan).

History
The longest lens in the system, both versions marketed in January 1960 at about ¥155,000: a doublet head of 1,800 grams that focuses no closer than 17 metres on the first box’s bellows and 21 on the second’s. It is the end of the mirror-box line and of Canon’s rangefinder ambitions at this length; the Canonflex took the heads over the same month.
A collector’s completion piece.
