Canon Demi
Posted: Sat Jul 12, 2014 4:41 pm
Canon made quite a few Half Frame cameras, from the first Demi in 1963 to the Sureshot MultiTele in 1988. The first Demi, pictured below, is a handsome and efficient camera that produces fine results. It is pictured with a Series V sunshade and the Flash Coupler which substitutes for a flash shoe-- it might take some perseverance to find that accessory.
Like the Fujica Half, the Demi has a five element f/2.8 lens; it is threaded for 27mm screw-in filters or a Series Adapter --Series V is about the right size and Kodak made an adapter that fits (No. 56). An exposure program sets apertures from 2.8 to 22 against shutter speeds from 1/30 to 1/250 ; there is no choice of speed and aperture except by setting the shutter to Flash and accepting the 1/30 speed. Time exposures are possible with setting “B” and the Demi accepts a cable release. Two marks on the lens read-out ring adjust the program up to +1.5 stops for filters or backlighting. Though the viewfinder has no frame lines, it is pleasant to look through and accurate. Focus is set by zone symbols on the lens ring which are converted to feet and meters by a permanent chart on the camera’s back. A lever film advance, a shutter release that benefits from a soft touch accessory, and a non-intuitive ASA/ISO setting complete the mechanics of the Demi. Unfortunately the selenium meter is the heart of the Demi’s picture taking and if it doesn’t work, the user has few choices except for the constant 1/30 speed and manual aperture setting mentioned above or to estimate the aperture that accompanies each shutter speed on the program (this has been figured out in an old Half Framer article copied below--though I can‘t guarantee it, it sounds about right). The meter on my unit works so I still use the Demi with the program. I remedy the lack of strap lugs by a handstrap screwed into the tripod mount.
The photos below were made with the Demi on Ilford Delta 400 a while ago, developed in D76, 1:1, and scanned at home. They come from Port Costa, California. The first one is a dyptych which some folks find to be a big plus for the HF format; I don’t have much luck with dyptychs , but, in this case, it is a good introduction to the other photos.
