Olympus E-1

The Olympus E-1 introduced in 2003 was the first DSLR designed from the ground up for digital photography. This contrasts with its contemporaries which offered systems based on reused parts from previous 135 film systems, modified to fit with a sensor size of APS-C.It uses the Four Thirds System lens mount and imaging system. This design choice means that because the CCD is smaller than a 35 mm negative, Four Thirds lenses and camera bodies can be made smaller and lighter than those of preceding SLRs.Characteristics:Lighter/more compact than contemporary DSLR bodies5 megapixel CCDGood dynamic range and exposureMagnesium-alloy bodyEnvironmental sealing (splash proof)"Supersonic Wave Filter" dust reduction system cleans CCD at each camera start-up (dust is shaken off the CCD)USB 2.0 and Firewire connectivityContinuous shooting 3 frames per second up to 12 framesHybrid white balance sensor (on external surface of camera and using CCD)User upgradeable firmware
