Canon made two fast lenses, the FL 50mm 1:1.4 and the FL 58mm 1:1.2, in order to compensate for the light loss. As the shutter curtain is permanently exposed to light without being protected by a moving mirror, a metal, rather than fabric curtain is used, which prevents the possibility of burning by being accidentally pointed at the sun, with ...
Canon TLb. Canon TLb. The Canon TLb is a 35 mm single-lens reflex camera introduced by Canon in September 1974. [1] [2] It features a Canon FD lens mount, and is also compatible with Canon's earlier FL-mount lenses in stop-down metering mode. The TLb was a cheaper version of the Canon FTb for the export market, as was the slightly later TX.
The Canon AL-1 was an FD mount, 35mm single-lens reflex camera introduced in March 1982. Its main feature was the "Quick Focus" focus-assist system that was aimed at those who had trouble focusing through the viewfinder—either novices, or those with poor eyesight—and was intended to head off competition from the first full-autofocus cameras from other manufacturers, such as the Pentax ME F.

Pitch correction. Pitch correction is an electronic effects unit or audio software that changes the intonation (highness or lowness in pitch) of an audio signal so that all pitches will be notes from the equally tempered system (i.e., like the pitches on a piano ). Pitch correction devices do this without affecting other aspects of its sound.
It uses an electronically controlled, electromagnet horizontal cloth focal plane shutter, with a speed range of 2 to 1/1000 second plus Bulb and flash X-sync of 1/60 second. The camera body is 87 mm tall, 141 mm wide, and 48 mm deep; it weighs 590 g. Most are black with chrome trim, but some are all black. The AE-1 is a historically significant ...
Time base correction (TBC) is a technique to reduce or eliminate errors caused by mechanical instability present in analog recordings on mechanical media.. Without time base correction, a signal from a videotape recorder (VTR) or videocassette recorder (VCR), cannot be mixed with other, more time-stable devices found in television studios and post-production facilities.
The Bonferroni correction compensates for that increase by testing each individual hypothesis at a significance level of , where is the desired overall alpha level and is the number of hypotheses. [4] For example, if a trial is testing hypotheses with a desired overall , then the Bonferroni correction would test each individual hypothesis at .
