Lens perspective is often given in millimeters ("mm") on the lens of a camera.
The smaller the number the wider the field of view (and the smaller things appear). The higher the number the smaller the field of view (and the larger things appear).
Most landscape shots are done around 28mm with a broad field of view (like a mountain or seascape). The human eye is equivalent to 50mm (that's often why you see most SLR/dSLR camera offer a 50mm equivalent).
If you go to a portrait studio most of the camera will have a 100-105mm lens on them as it offers a good field of view and allows the photographer to be a comfortable distance away (no one likes a lens sticking in their face).
At 280mm you really begin to magnify you subject. If you like to shoot nature shots or sporting events, chances are you will be shooting at this length.
Most digital camera makers would advertise this camera as a "28MM lens with 10x Zoom". The 10x is a multiplier of how many times you can increase that 28mm focal length (in this case 28mm x 10 = 280mm).
If you're looking at point and shoot cameras go for one that offers true optical zoom vs. digital zoom. The difference in quality between optical and digital zoom is significant and the results you get with optical zoom are far more pleasing.
Happy shooting!

they mean that if you were using a film camera, it would have a focal range of 28 to 280 mm, 10x optical zoom. 28mm is the minimum opening, and 280 is the max. Because it's digital, they use "equivalent." If you recall film cameras, they had 10mm, 26mm, 35mm, etc.

the larger 2nd number show how far your lens could zoom. let's say you have a 200mm and a 280 mm , a 280 mm could let you zoom in object from further distance. a lens that could zoom very far normally sacrifice the nearer distance.
let's say you have a lense starting with 28mm and 1 starting with 40mm shooting at same object at a same distance, a lense starting with 40mm bring you nearer to the object while a 28mm will have a wider picture with the object and the background.

It relates to 35mm photography. Since most amateur photography was done on 35mm prior to the digital explosion, it gives people familiar with 35mm film cameras a frame of reference.
