FL Lenses by Date

A List of the FL Lenses by Date of Issue

When Canon brought out its first SLR in in 1959 the era of communication between lens and camera began. Initially there was no through the lens metering but manual focusing required the lens to remain open at maximum aperture so that maximum light was available for focusing.

To accomplish this the photographer selected his aperture on the Aperture Selection Ring but only when the shutter was pressed did the lens stop down to the selected setting. Once the picture was exposed, the lens returned to the open position. The lens worked with the body and they communicated information back and forth. The complexity of this information flow increased with time which in turn drove lens development and a successive series of lens mounts.

The original SLR’s came out with the “R” series of lens mounts. These gave way in April of 1964 to the “FL” lens mount on the Canon FX camera. However, as through the lens metering developed and auto exposure became a reality more data had to be transferred between lens and body and the FL system was not sufficient. In March of 1971 it was replaced with the “FD” series of lenses. FL and FD apparently have no particular meaning and I have not seen any explanation of why they were chosen.
