top left-hand side of the camera (from the photographer's perspective). This switch also selected self-timer mode and had a Lock position. Exposure modes The T70 supported eight different exposure modes. These were: Program AE (autoexposure). In this standard mode, the camera judges the shutter speed and aperture for average photographic scenes. Wide Program AE. Here, the camera is biased towards choosing narrow apertures for greater depth of field, most often useful with wide-angle lenses. Tele Program AE. Here, the camera is biased towards choosing wider apertures for narrow depth of field and fast shutter speeds, most useful with telephoto lenses. Shutter-priority AE. Here, the user selects the shutter speed and the camera chooses the correct aperture. Programmed flash AE. This is designed to work with the Speedlite 277T dedicated flash unit. Electronic flash AE. For flash exposures with non-dedicated flash units. Manual. Here, the photographer chooses both aperture and shutter speed. Stopped-down AE. For use with older FL-mount lenses that do not support open-aperture metering. Also for use with macro photography attachments such as extension tubes and bellows, and for using non-Canon lenses with an adaptor. Cannot be selected with an FD lens attached. Data back A dedicated Command Back 70 supported date and data imprinting as well as time exposures, to take a photograph at a programmed time, and to take time-lapse photos at programmed intervals. The shutter of the T70 was not battery dependent during bulb exposures, and was one reason why the command back could support timed exposures of several hours duration. Reception When it was introduced, the Canon T70 was considered technologically advanced compared to other SLR cameras. Reviewing the camera in Popular Science, Everett Ortner said that the T70 "could be...too good for amateurs. It is certainly far removed from those other technological wonders designed for amateurs". He praised the high degree of control, coupled with automation, that the T70 allows photographers to use, reducing "the role of the camera from that of master to servant."
