What f2.7 - f3.5/f8 mean?
F-stop numbers represent the size of the aperture. The bigger the f-stop number, the smaller the aperture. Conversely, the smaller the f-stop number, the wider the aperture.
Indicators like f2.7 - f3.5/f8 refers to the range of openings of which a zoom lens can operate within.
In this case, read the indicator as f2.7 - f8 when the camera is most zoomed out (Wide-angle.) Read the indicator as f3.5 - f8 when the camera is most zoomed in (Telephoto.) That is what f2.7 - f3.5/f8 means.
(I still can't figure out something. In this case, f2.7 is at it's wide-angle, because a larger aperture size give rise to a wider viewer range? While at f3.5 is at it's telephoto, because a smaller aperture size means a smaller viewer range?)
