focus on k-x

question where on the k-x can you see what focal length you are in without having to look at the lens because i see picture post where it says
lens: 18-55 @57mm how is that so if the lens only goes to 55mm

i am am only about a month in with this k-x (my first dslr ever) im just trying to understand lens and what it takes to take a clear picture & stuff

The 18-55 can't do 57mm. It can't even really do 55mm. The only way to know what focal length you're at is to look at the lens. Also, you can see what focal length a picture was taken at by looking at the embedded EXIF information, or just by reviewing it on your camera and pressing the Info button until all the details are shown.

The only way I can think someone could claim 57mm focal length on an 18-55mm is if he/she was giving the equivalent focal length on a film camera.

On other Pentax cameras, you can hit the Info button to see wha focal length the lens is currently reporting. The display doens't update as you zoom. Note "focal length" and "focus" (the titleof this thread) have nothing in particular to do with each other...
