Canon FL lens mount

When Canon FL -mount it was the second generation of the Canon R- bayonet, a lens mount for small format SLR cameras. It added a transmission element, which enabled the automatic diaphragm.

FL Bayonet

Period of time

The FL- bayonet was released in May 1964 and was replaced by the 1971 published FD bayonet. Some lenses but remained for a time in the program. The FL 1200 mm, f/11 even appeared only in June 1972 and remained until the late 1970s in the program.

Construction

The FL- bayonet attached to the R- bayonet added a lever to dim, who was with lens attached below the mirror. This automatic diaphragm allowed despite already a Set Aperture bright viewfinder image, because the lens only dimmed when triggered. For the TTL metering, stopping down was also required, what happened to press the exposure lever. The aperture priority could be switched off to run FL lenses to the R - bayonet cameras, at the uncoupled intermediate rings, bellows or in reverse position. For this, the iris diaphragm lever on the lens by hand had to be pushed so far until he einrastete, or a specially existing levers are allocated on some lenses.

Comparison with the super - Canomatic

In the super- Canomatic that occurred on lenses for the R- bayonet could be dimmed only once per shot. Then, the system had to be brought up with the film transport only again. This made it unsuitable for TTL metering, because this was only for the exposure and then dimmed again for recording.

Cameras

For the FL- system offered the following Canon cameras, which all had a tracking metering, the FX with CdS photocell on the housing cover, the other cameras with TTL metering:

Dissemination

The FL bayonet obsolete very quickly as beginning with the Topcon RE, which also appeared in 1964, more and more cameras with aperture metering came out. In particular, the successful Minolta SR- T 101 Canon could be challenged on anything. Thus, the FL- bayonet was only a moderate distribution. This changed with the subsequent FD system.

FL lenses

Special lenses

FL 19mm f/3.5

The rear lens of the Canon FL 19 mm was located very close to the film plane, as a result, it towered far into the mirror box. It could only be used on cameras with at Spiegelarretierung folded mirror. To the lens was a seeker, who was placed on the hot shoe. In contrast, had the R in the name of the FL 19mm f/3.5 on hi R, that it is a retro-focus construction acted ( distance between the rear lens of the image plane is greater than the focal length ). This objective could be stated as usual.

FLP 38mm, f/2.8

The rear lens of the FLP 38mm f/2.8 sticking further than usual in the mirror box inside. Therefore, it could be recognized only to the Canon Pellix whose mirror required less space, because he was certain, and consequently not the orbit had to be kept free, which described the movable mirror when lifting.

Fluoritobjektive

With the FL lenses Canon also began to construct high-performance telephoto lenses. The first construction of this type came in the spring of 1969, the FL -F 300mm, f / 5,6 and FL -F out 500 mm, f / 5.6. They had a lens made of fluorite ( fluorspar from an artificially grown crystal). In early 1974, followed then the FL 300 mm, f / 2.8 SSC Fluorite.

Macro lenses

The lenses FLM 50 mm, f / 3,5 and FLM 100 mm, f / 4 were corrected as Nahobjektive for close range and had a special long auger, with which it from infinity to a scale of 1: 2 were able to focus. Using an extension tube of 25 mm or 50 they reached the scale of 1: 1
