Значит опять не дошло. Третий раз пробовать не буду.
Слава богу. Уж лучше никак не объяснять, чем объяснять так. Ощущения бреда меньше.

he diagonal size of the 4/3-type image sensor is about half that of a 35mm film sensor. This means that the focal distance required to obtain a given angle of view is half that needed for a 35mm film camera. As a result, the optical system can be made much smaller. Moreover, because the effective aperture can be reduced without reducing brightness, the Four Thirds system makes it possible to design much brighter lenses.
For example, a Four Thirds telescopic lens equivalent to a 35mm 300mm lens can be implemented with a focal length of 150mm, and it can also offer wide aperture and high brightness corresponding to f2.0 while the maximum brightness available with a traditional lens was f2.8.
Понимаю, что оффсайт системы 4/3 для Вас - не авторитет и маркетинговый бред, на который повелись бедные ЧКФР вроде меня, но почитать почитайте.
