CBQer posted:One of the things about buying s DSLR is the fact that so many of the "kits" both Nikon and and Canon offer the the 18-55 selection. That always struck me as an odd combo for a zoom. It requires that you have the big tele readily available for the longer shots that we so often have to take. With the higher focal length available such as a 125mm I have some telephoto ability.

Most kits from both Nikon and Canon come with cameras that have crop sensors (DX sensors). More expensive DLSRs have full frame sensors (FX sensors). An 18-55mm lens on a camera with a crop sensor is roughly equivalent to a 28-80mm lens on a full frame or traditional 35mm film camera. IMHO a 28-80mm lens is kind of the standard for an indoor or close quarters zoom. I have one for my 40 year old film camera.
Canon's crop sensor uses a 1.6 multiplier and Nikon uses a 1.5 multiplier. So the math works out like this:
Canon 18-55mm = 28.8-88mm and Nikon 18-55 = 27-82.5mm
Now the "roughly equivalent" statement also includes depth of field. Even though these combinations yield focal lengths around the classic 28-80mm lens, the depth of field remains the same as the actual focal length of 18-55mm. But with that said, I've only ever herd 1 pro photographer complain about the depth of field difference. A crop sensor with any lens gives you a little more room if you screw up.
The photo in the link was shot with a Nikon D80 (DX sensor) and a Tamron 18-50mm lens back in 2007.
