F-number For the numbers, a sequence of numbers which use the square root as the common ratio based on 1 (one) is used. The aperture scale consists of approximate values which are two times as great as or half of the basic number of the amount of light that passes the lens by each step (1.0, 1.4, 2, 2.8 and so on). However, the maximum F-number may not be appropriate to this sequence of numbers.
Cleaning of Camera, Lens and Video Products For the purpose of helping to sanitize your Canon Camera, Lens and Video products, it is recommended that you clean parts touched with the hands such as camera grips, dials and lens exteriors.
