DSLR camera lens question?
Im just curious what the 15mm-55mm what that means when looking at lenses? Other numbers too but still.
Also im interested in a cam but it is only a 3x zoom but if you buy the lenses does that add zoom????
Thanks, im new to the SLR cameras.
Update:It was a sony dslr.... with a 15mm 55mm lense.

its the focal lenght of the lens.
15mm is the distance between the
the image sensor, or film, and the
lens glass. the lower the number,
the wider the lens and the higher
the number, longer the focal lenght
thus the more zoom. if you divide
the 2 numbers you get the zoom
number. 55÷15=3.6 meaning 3x zoom
power. a 18mm-200mm lens has a zoom
power of 11x
15mm-55mm means it is a zoom lens that covers everything from the 15mm to 55mm focal length.
If the camera you are looking at says it is a 3x zoom, then it is not a DSLR.
You really need to read a couple good books about basic DSLR photography before you spend any money. If you don't even understand really basic stuff like the focal length of a lens, then you will end up wasting your money on an expensive camera you don't know how to use.
If the camera you are looking at says 3X optical zoom, that's what you have. It's a point and shoot, not a DSLR. You can't add different lenses to a point and shoot. Borrow a book from local library on the Basics of Photography.
