QL MECHANISM SIMPLIFIES QUICK LOADING
CANON has designed and developed a simplified Quick-Loading mechanism This mechanism has been incorporated into the CANON FT QL. Only three steps are required when loading new film.
Most models that came with a "XXX QL" means it was employed with such similar system for quick and responsive film loading. The Pellix QL mentioned earlier was using such similar mechanism.
1. Open the back of the camera.
2. Place the film leader onto the specially designed take~up mechanism
3. Close the back of the camera. The camera is now loaded and ready for use. The Quick-Loading mechanism will take any type of 35mm film, color or black and white, from any part of the world. There is no waste and no possibility of incorrect threading. What is more, the QL mechanism enables the photographer to load the camera under poor lighting conditions such as the times when the CANON BOOSTER is being used.
The Canon FT QL may look like an stone age product to many high tech Autofocus users now, but it represents the result of years of research in the field of camera design and manufacturing. It was easily one of the fine range of Canon cameras with the most advanced Through-The-Lens exposure system employing a quick return mirror available during the mid sixties to early seventies.
Innovations such as their exclusive new Quick-Loading mechanism, an ultra-sensitive CdS exposure meter ensures accurate exposure, and each model comes with the durable and rugged construction that virtual trouble-free service that results from their accumulated precision engineering, searching inspection and faithful adherence to quality. The FT QL and Pellix QL are still available today and actively traded in the used market, most are still functional and it proves to be an extremely well made SLR from Canon.
You cannot skip the lenses when you mentioned a camera body. Every conceivable type of photography becomes possible when different lenses are employed. The Canon FT QL accepts as many as 22 different types of lenses. For instance, the FL 19mm F3.5R, a super wide-angle lens which can be mounted on the camera without lifting and locking the mirror. The Macro FL 50mm F3.5 lens has ultra-high resolving power admirably suited to microphotography The FL 55mm-135mm F3.5 and FL 85mm-300mm F5 are high-performance zoom lenses with automatic, preset aperture diaphragms and were especially designed for CANON cameras. Super telephotography is possible with the use of the FL 1000mm F11 lens. The possibilities are unlimited and, by adding interchangeable lenses to your equipment as the need arises, it will be possible to shoot any subject be it technical, scenic, portraiture, sport or news.
Also a host of attachments are available - Bellows FL, Extension Tube FL, Slide Duplicator and many other accessories.
Note: A simplified and cheaper version of the FT QL was introduced in 1968 and was referred as 'TL', this camera was for the overseas mass market. The maximum shutter speed was only 1/500 sec. The camera was without a self-timer and QL feature, but it retained stop-down TTL metering. Although most TL cameras did not have QL feature, but there was known to have a small quantity which possessed within this QL feature. Source: Canon Marketing.
