Re: Newbie: Will I notice the difference with a prime lense?

FF (full frame) means the camera's sensor is the same size a a 35mm frame, around 36x24mm, while an APS-C sensor is around 24x16mm. The actual focal length of lenses remains the same for both systems, but APS-C appears to have a 1.5x magnification compared to FF. So your 18-55mm lens has the about the same field of view of a 28-80mm FF lens. For your A57 this means that you gain reach on the telephoto end, but lose on the wide angle lens.

As other people have stated, the 35mm f1.8 is a great lens and will give better quality images than the kit lens. The    wider aperture will allow you to have more control over the depth of field in you photos.
