Photos: Prototypes show Sony SLR lens plans

Sony showed three other lenses for its mainstream SLRs: a 50mm f1.8 model, an 18-55mm f3.5-5.6 model, and a 55-200mm f4-5.6 model.

The "fast fifty" lens is an ages-old design for the SLR market offering a wide aperture for low-light shots but no zoom range. The others are common as "kit" lenses bundled with the initial purchase of an SLR.
