I think it is number three in the market or I could be making that up. Could well be right. Not my church, so I'm not sure. [grin]
I basically let the camera do the work too, but I like to know what some of the numbers actually mean. Most kit and standard zoom lenses have minimum apertures of about f/3.5 to 5.6, which are viewed as reasonable. Fast zoom lenses tend to open down to f/2.8, and prime (non-zoom) lenses can go down to around f/1.2 for what reddragdiva has been known to refer to as "honking light-buckets".
The number after the f/ is the second half of a ratio, indicating how much of the lens is actually letting light in. So something taken at f/2.8 means that the aperture opening is 1:2.8 of the lens (or 1/2.8, for fractional people) - about a third. If it's taken at f/10, then it's about a tenth.
