Pentax has launched a consumer-level standard zoom lens for its range of digital SLRs: the slightly unwieldily named smc PENTAX-DA 17-70mmF4AL[IF] SDM. The lens offers the useful equivalent zoom range of 26-107mm combined with a maximum aperture of F4.0 and Pentax' SDM system which uses a supersonic motor for focusing. The latter is only compatible with Pentax' latest DSLR offerings - the K20D, K200D, K100D Super and K10D. On all other bodies focus mode will default to manual focus.
