The 330 has a range of in-built features that are usually only found on higher-end SLR cameras (such as double exposure mode); in terms of Olympus' product line, it would sit below the otherwise similarly featured L series as it is not an SLR. With a 38-105mm zoom lens, the 330 follows on from the 300 with a viewfinder that is coupled to the lens zoom - while it is not an SLR, the viewfinder zooms to represent the lens's view (the 300 was reportedly the first camera to feature this functionality).
