The Canon Vt was introduced in 1956 as a successor to the Canon III and IV series of cameras. The "V' is the Roman numeral for five, while the "t" stands for trigger. Canon introduced a camera that was vastly redesigned over previous models of Canon rangefinders, and the Vt was meant to better compete with the Leica M3 that had been unveiled in 1954.
For example, the Vt has a combined rangefinder and viewfinder. The viewfinder uses a rotating prism that allows the user to change viewfinder magnification between three settings: 35mm (wider than even the Leica M3), 50mm and "RF" which is meant for magnified, critical focusing but may also serve as a stand-in for 135mm lenses.
The Vt also moved to a hinged back door as opposed to the removable base plate. The "trigger" referenced in the camera's name comes from the built-in rapid advance lever in the base of the camera. The Vt removed the old-style advance knob and replaced it with this base trigger, which allowed for extremely fast film winding but could be more cumbersome if the camera was mounted to a tripod, used in portrait orientation, or had a long telephoto lens mounted.
The Canon Vt still makes use of the M39 threaded lens mount, keeping it compatible with the large inventory of lenses that previous Canon (and Leica) cameras use.

Canon Vt
When we consign cameras, we generally sell bodies and lenses separately. We do this because equipment sold apart is, generally, more flexible in terms of potential customers: someone wants a lens but already has a camera, or wants a camera but with a different lens. That sort of thing. Also, as cameras and lenses get kitted up, their combined price becomes higher, sometimes making them less accessible to buyers. There are, however, some occasions where we keep a camera together with a particular lens because they belong together. As much as we would love to see this Canon 50mm f1.2 M39 lens available for sale separately, it belongs with this Canon VT; in no small part, because of the addition of the Auto-Up close up adapter. These three things together are a family and we just didn't have the heart to split them up. Look how beautifully they go together.
