The E-5 is the flagship model of the Olympus E-series digital SLR camera lineup. The E-5 incorporates an array of impressive the features such as the multiple exposure, electronic level gauge and imager AF first introduced on the E-30, the advanced image processing engine popularized by the Olympus PEN series, plus art filter and HD movie functions. Like the E-3, the E-5 features a dust- and splash-proof body that makes extensive use of seals and is made of lightweight but rigid magnesium alloy. Any dust that does manage to penetrate to the image sensor is quickly removed by Olympus's industry-leading dust reduction system.
