What is the definition zoom Slr Camera?

I've been working with Compact Digital cameras this year (mostly from the Powershot Canon S3 IS), and just made the switch to Slr Cameras. The lens that came with my new camera is satisfactory for my purposes (Portrait of problems), but I do not feel I'd like to zoom. It is an EF-S 18-55mm f/3.5-5.6 IS Lens. What I wonder is how do you tell how much zoom SLR camera has in relation to Digital Cameras' optical zoom?

Zoom is actually a fairly useless. Zoom is only the relationship between the distance focal highest to lowest. The 18-55mm lens is about a 3x zoom (55/18 = ~ 3), but a target of 100-300mm is a 3x zoom. The reason for this term point and shoot works is that everyone has the same focal length wider, so you are comparing apples to apples. For SLR will have to learn to think in terms focal length (a physical measurement of one aspect of the lens). The human eye is almost the same as a 50mm lens on a full frame or Film Camera. Any length broader focus less than 50 mm show a broader view. Above shows a closer view. A complicating factor is that not all cameras are full frame. To make a meaningful comparison you need to turn your lens focal length of the full effect within the focal length. Virtually All Digital Slr that cost less than $ 3,000 are not full frame. To find the effective focal length of a lens in these cameras, multiplies it by 1.5 times for Nikon cameras and 1.6 times for Canon cameras.
