Can some one please explain to me what the following numbers mean on the side of my lens?

1,8 / 5,4 - 54

Thanks.

1,8 = the maximum aperture value is f/1.8 at full wide angle.

5,4 - 54 = the focal length of the lens is 5.4mm at full wide angle and 54mm at full telephoto (or in other words, it has a 10x zoom range). Hope this helps,
