Photography + Computer The computer age was invitably found an in-route into SLR camera design - apart from affecting life-styles and the world we live in. And Canon foresees that as early as 1976 when the Canon AE-1 was introduced to the world. In 1984, a revolutionary new Canon camera was launched and it was changing the way we look at camera and photography. That camera was the Canon T70 model.
 |
Like today's computers, the second model of the Canon T series was designed to perform a multitude of tasks with split-second response and unfailing accuracy. |
Data input into the T70's microprocessor
brain give not one but three daylight programmed exposure modes. These select
the most appropriate aperture/shutter speed combination for the lighting and the
lens in use: wide-angle, standard or telephoto. Flash photography is also
fully programmed. For fast-paced action, there's Shutter-Priority AE and when
the situation demands, Manual override.

Another feature that makes the T70 really two cameras in one was its dual metering. Flick a switch to select either Centerweighted average or Selective Area metering. |
Although the T70 was a quantum advance in camera technology than the first T-series model, the all programmed-AE-only T-50, the basic concept of the T series model remains - advanced doesn't mean complicated, simplicity in control and operation are the order of the day. The T70 was delightfully simple to use. With a streamlined compact design.

Gone was the tradittional shutter
speed dial where the selection has been replaced with push button operations, no
more manual film advance lever which was replaced with a built-in integral motor
for automatic film advance and even rewind. And in another departure from
the conventional, a large LCD panel displays all essential information. LCD
(Liquid Crystal Display) was used because it is highly power efficient than LEDs,
consumes only 1/10000 power of equivalent of LEDs. Only two AA-size alkaline manganese
batteries are required to power all the camera's automatic functions.
Another significant breakthrough with the T-series was a new dedicated accessory,
the Command Back 70, which performs like a command centre, like recording
data on the film automatically and it will even instruct the camera to take pictures
- regular shots and timed exposures - at set intervals. It was a vast improvement
over the earlier T50 which was not designed to accept a databack. Naturally, the
T70 also accepts the full line of FD lenses and accessories. The T70 was designed
and aimed more directly at serious amateurs and professionals alike.

Other interesting features like
a sleek profile, superb balance and handling. Power-saving design. Reliability-enhancing
features. System accessories including multipurpose Command Back 70 and programmed
Speedlite 277T. Programmed Versatility The T70 is programmed for every conceivable
photographic situation. The Program AE was a great improvement over the earlier versions
used in the multimode Canon A-1
or the simpler AE-1 Program,
as it has more options to fine tune exposures.
 |
Using the T70 and its companion Speedlite 277T is far more flexible than any Canon A-Series cameras. While its built-in film winding rate is not as fast as the Canon A-1 or AE-1 Program fitted with Motor Drive MA, you get a lighter package despite the more advanced technology the T70 has. All three programs can be used with any lens Programmed Flash and Electronic Flash AE are provide with dedicated flash units. |
Warning: The T-70 featured here (for that matter, all the A and T series models) uses the previous manual focus FD mount and thus are not compatible with the many current autofocus EOS mount optics or accessories. If you have already owned a SLR system, I don't actually recommend a buy - unless for some specific personal reasons like it comes in really cheap or may be if you have already built-up a FD system over the years and you don't want to abandon them (Because it doesn't make sense, an entry EOS model will be more logical if the price is the same). I don't like to mis-led anyone who comes into my site, please make note of that before any decision is made.
