Its my observation most entry level DSLR cameras have cropped sensors. Greater zoom is a consequence of cropped sensors. As I recall back in days of film photography wide angle was 24mm, normal angle was 50mm and telephoto was 300mm. Again I'm oversimplifying but this is not a math or science journal, its a nature photography journal. That said if you had these three lens focal lenghts you could shoot most anything in nature, landscapes, scenery and close up wildlife 24mm, 50mm and 300mm respecctively.
Know that when cropped sensors are 2/3 the size of 35mm film, the sensor size reduction results in focal lengths 1.5 times greater than film. Its pretty cool that an old 300mm lens now has an effective 450mm reach. Much better zoom for a relatively inexpensive price.
My first thought was that longer reach would only result in camera shake and motion blur. In my mind there was no way I could shoot anything with the zoom lens, multiply by 1.5 and get good results. Well they fixed that problem too. Lens stabilization is the solution.
Depending upon the brand of camera everyone has a different name: vibration control, vibration reduction or lens stabilization. What ever its named does not matter. I don't know how it works and I don't care. Its simply something that works. Effectively has made using my tripod less and less important. You can reasonably shoot a 300mm lens at 1/60 of a second and get good clear shots. Anything slowwer and you begin to blur. But its real magic as in the past anything under 1/250 second would blur on film.
Short story is you can now shoot much more freehand plus have greater ablity to zoom. Just be sure your lens has stabliztion turned on. I'm sure there is something that is traded off somewhere but I can't figure out what it is.
