Canon Demi EE171966

History

Canon launched the original Demi in 1963 as a compact half-frame aimed at the amateur market, competing with the Olympus Pen series. The EE17 arrived in 1966 as the premium variant with a faster f/1.7 lens and improved AE system. "EE" stood for "Electric Eye" — Canon's marketing term for automatic exposure. Canon produced the Demi series through the early 1970s, when compact full-frame cameras began to displace half-frame in consumer preference. The EE17 is the most desirable Demi because of its lens speed; clean examples are harder to find than the standard Demi or EE models.

Why It Matters

Half-frame cameras offer a peculiar trade-off: half the resolution of standard 35mm per frame, but twice the shots and a naturally vertical default orientation (the camera shoots landscape but the negative is portrait). The EE17's f/1.7 lens is remarkably fast for a half-frame — the Yashica Half 17 was the first with this aperture (also f/1.7), but the Canon EE17 matched it. In practical terms, f/1.7 on a half-frame is approximately the same as f/2.4 on full frame for depth-of-field purposes, so the background blur is limited but the low-light performance is genuine.

Canon's build quality on the Demi EE17 is a step above most half-frame cameras. The finder is clean, the zone-focus ring is positive, and the AE system is well-calibrated on working examples. Used prices have risen with the film revival: expect $40–150 for a working body.
